Abstract

Abstract Cognitive decline is a major non-motor complication in early Parkinson’s disease (PD), but predicting its progression remains challenging. Using data from 193 participants in the Early Parkinson’s Disease Longitudinal Singapore (PALS) cohort, we evaluated whether longitudinal blood biomarkers—neurofilament light chain (NfL) and total tau (t-tau)—could improve prediction of cognitive decline, defined as a one-point annual or sustained two-year drop in Montreal Cognitive Assessment scores. We applied three variable selection methods and five machine learning models across seven feature sets. Overall, 23% of participants experienced cognitive decline over five years. The XGBoost model trained on Random Forest–selected variables achieved the highest performance (AUC = 0.806), a substantial improvement over the baseline-only model (AUC = 0.560). Key predictors included diastolic blood pressure and summaries of t-tau and NfL. Time-varying biomarkers improved predictions over baseline data alone, supporting their integration with machine learning for early cognitive risk assessment in PD.

Health sciences/Biomarkers Health sciences/Neurology Biological sciences/Neuroscience Figures Figure 1 Figure 2 Introduction Parkinson disease (PD) is the second most common neurodegenerative disorder, affecting over 10 million people globally. With aging populations, its prevalence is expected to double by 2040, increasing burdens on healthcare systems and caregivers. Although PD is primarily defined by motor symptoms such as bradykinesia, rigidity, and tremor, non-motor features—particularly cognitive impairment—contribute significantly to morbidity [ 1 – 4 ]. Cognitive decline affects up to 80% of patients, with many progressing from mild cognitive impairment (PD-MCI) to Parkinson’s disease dementia (PDD) within a few years of diagnosis [ 5 – 10 ]. Cognitive deficits in PD have serious clinical and societal impacts, including reduced quality of life, loss of independence, and higher rates of institutionalization. Healthcare costs for patients with PDD are twice those without dementia, and caregivers face increased psychological and financial strain. Predicting cognitive decline remains challenging due to heterogeneous disease progression. Early identification of at-risk patients is crucial for timely intervention, counseling, and improving clinical trial design [ 7 , 11 – 14 ]. Current prognostic tools poorly predict cognitive outcomes in PD. Clinical scales like the Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) focus on motor symptoms and offer limited insight into cognitive decline. While Cerebrospinal fluid (CSF) biomarkers and neuroimaging provide some prognostic value, they are invasive, costly, and impractical for routine use [ 15 , 16 ]. In contrast, blood-based biomarkers are minimally invasive, cost-effective, and feasible for repeated assessments [ 17 , 18 ]. Neurofilament light chain (NfL), a marker of axonal injury, correlates strongly with CSF levels and is linked to disease severity and cognitive decline in PD [ 19 – 23 ]. Similarly, total tau (t-tau) and phosphorylated tau181 (p-tau181) have been associated with cognitive dysfunction [ 24 – 26 ]. Prior studies have reported elevated plasma NfL and t-tau in individuals with PD who exhibit early cognitive deficits, and combinations of plasma α-synuclein, p-tau181, and Aβ-40 have been proposed as potential biomarkers [ 26 – 34 ]. However, the vast majority of these investigations rely on cross-sectional data, limiting their predictive power. Longitudinal biomarker trajectories, such as changes in NfL and t-tau, may better reflect disease progression [ 35 , 36 ], yet few studies have evaluated their predictive utility in early PD or combined them with clinical data to improve prognostic accuracy [ 37 ]. Advances in machine learning (ML) have transformed neurodegeneration research by enabling the analysis of complex, high-dimensional data [ 38 – 40 ]. ML can detect non-linear patterns and interactions often missed by traditional methods[ 41 ]. Prior work using data from the Parkinson’s Progression Markers Initiative (PPMI) has shown that ML models can achieve high accuracy in predicting disease progression by incorporating multimodal data, including motor scores, biospecimens, and patient-reported outcomes [ 42 ]. However, the utility of ML for predicting cognitive decline in early PD using time-varying blood biomarkers remains underexplored. Building on our prior work predicting cognitive decline in early PD using baseline features (AUC = 0.93) [ 43 ], we now examine whether adding longitudinal plasma NfL and t-tau measurements improves prediction. Using data from the Early Parkinson’s Disease Longitudinal Singapore (PALS) cohort, we apply multiple ML algorithms to model cognitive decline over five years. Our objectives are to: (1) assess the added value of longitudinal biomarkers, (2) identify key predictors using advanced feature selection, and (3) develop a clinically relevant risk prediction tool. Methods Study Design, Participants, and Variables This prospective observational study used data from the PALS cohort, which tracks clinical, cognitive, and biological changes in early PD. Participants were enrolled from specialist clinics in Singapore (2014–2018). Inclusion criteria were PD diagnosis within 1 year, symptom onset within 2 years, and meeting the National Institute of Neurological Disorders and Stroke criteria. Participants required at least six years of education. Exclusion criteria included comorbidities likely to confound outcomes or hinder follow-up (e.g., malignancy, unstable cardiovascular disease) [ 44 , 45 ]. Of 214 participants recruited, 193 completed baseline assessments and had at least three years of cognitive follow-up, comprising the final analytic cohort. Informed consent was obtained; the study was approved by the Singapore Health Services Centralized Institutional Review Board. Participants underwent detailed annual evaluations over five years, including clinical, cognitive, and laboratory assessments. Cognitive performance was measured using the Montreal Cognitive Assessment (MoCA). Venous blood samples were collected at baseline, year 3, and year 5. Primary biomarkers—NfL and t-tau—were quantified using ultra-sensitive single-molecule array (Simoa) assays. For these biomarkers, four summary features (minimum, maximum, mean, and standard deviation) were computed across time points to capture both levels and variability. Additional baseline biomarkers included suppression of tumorigenicity 2 (ST2), apolipoprotein E (APOE) genotype, p-tau181, and alpha-synuclein gene promoter repeat length (REP1). The primary outcome was cognitive decline, defined as either a ≥ 1-point annual decrease in MoCA score or a ≥ 1-point drop sustained across two consecutive years during the five-year follow-up. This threshold was selected to reflect subtle but clinically meaningful cognitive changes. Baseline demographic characteristics included age, sex, body mass index (BMI), years of education, smoking history, alcohol use, and consumption of coffee and tea. Clinical features comprised Hoehn and Yahr stage (HY), baseline MoCA score, MDS-UPDRS Part III score, systolic and diastolic blood pressure (SBP and DBP) measured in both lying and standing positions, and comorbidities including hypertension, diabetes mellitus, hypertension and hyperlipidemia. Statistical Analysis Missing data were addressed using a random forest (RF)–based imputation method [ 46 ]. All continuous variables were examined for clinical interpretability, and when appropriate, were dichotomized using clinically relevant thresholds. In the absence of established cutoffs, the Youden index was used to derive optimal cut-points from ROC curves to maximize sensitivity and specificity [ 47 ]. Descriptive statistics were used to summarize all variables. Continuous variables were presented as mean (standard deviation) or median (interquartile range), and categorical variables as counts and percentages. Associations between individual predictors and cognitive decline were assessed using univariate logistic regression, reporting odds ratios (ORs) with 95% confidence intervals (CIs). To identify the most informative predictors, we applied three complementary variable selection methods. First, RF importance scores were used to rank variables by mean decrease in Gini impurity, retaining only those above the average score. Second, the Shapley Variable Importance Cloud (SHAPvIC) method quantified each variable’s contribution using SHAP values; variables with 95% prediction intervals entirely above zero were selected. Third, we applied gain-based feature importance from Extreme Gradient Boosting (XGBoost), keeping variables with scores above the mean. This triangulated approach enhanced both statistical robustness and consistency across methods. For predictive modeling, we trained five supervised ML algorithms: RF, neural network (NN), k-nearest neighbors (KNN), XGBoost, and Light Gradient Boosting Machine (LightGBM). Each algorithm was evaluated across seven different feature sets: time-varying biomarkers alone; baseline variables alone; a combination of both; and subsets derived from each of the three variable selection strategies (including a reduced version of SHAPvIC for parsimony). The dataset was randomly split (80:20) into training and test sets, stratified by cognitive decline status. Hyperparameters were optimized via five-fold cross-validation on the training set. For RF, we tuned the number of trees and number of predictors considered at each split. For XGBoost and LightGBM, we optimized learning rate (0.01–0.1), number of boosting rounds (50–500), maximum tree depth (3–7), and L1/L2 regularization terms (range: 0–1). NN models varied in hidden layer size (1–5) and applied weight decay (0–0.1), while the optimal number of neighbors (k = 1–10) was selected for KNN models. Model performance was assessed on the held-out test set using multiple metrics. Discrimination was evaluated via AUC with 95% CIs from 1,000 bootstrap resamples. Additional metrics included sensitivity, specificity, accuracy, precision, recall, F1 score, and Brier score. The F1 score, the harmonic mean of precision and recall, balances false positives and negatives. The Brier score quantifies the accuracy of probabilistic predictions. Sensitivity and specificity were calculated at the optimal threshold via Youden’s index. Calibration was assessed using decile-based plots comparing observed and predicted event rates across 10 bins. All analyses were performed using R version 4.2.2 (R Foundation for Statistical Computing, Vienna, Austria). Statistical significance was set at a two-sided P Value < 0.05. Results A total of 193 participants with early PD were included. At baseline, the mean age was 63.8 years (SD = 8.9), 58% were male, and the median education duration was 11 years (IQR = 8–15). The mean MoCA score was 25.4 (SD = 2.8). Disease severity was mild to moderate: 62% in HY stage 1, 30% in stage 2, and 8% in stage 3. Over five years, 44 participants (22.8%) experienced cognitive decline (Table 1 ). Higher education (≥ 10 years) was protective (OR = 0.4; 95% CI: 0.2–0.7; P = .0006), while elevated blood pressure increased risk: lying DBP (OR = 2.6; 95% CI: 1.3–5.2; P = .009), standing DBP (OR = 2.1; 95% CI: 1.1–4.3; P = .045), and lying SBP (OR = 2.1; 95% CI: 1.1–4.3; P = .045) (Table 1 ).

To identify the most predictive variables, thirty candidate features were assessed using three feature selection methods. The RF approach identified twelve variables, including years of education, lying and standing DBP, and four summary statistics (minimum, maximum, mean, and standard deviation) for both NfL and t-tau, along with baseline p-tau181 levels (Fig. 1, top row, left). The ShapleyVIC method selected fourteen predictors, which included t-tau (minimum, maximum, mean, and standard deviation), NfL (minimum and mean), as well as baseline MoCA score, hyperlipidemia, coffee and alcohol consumption, lying and standing DBP, p-tau181, and gender (Fig. 1, top row, right). The XGBoost-based method identified eleven key features, including the full set of summary metrics for both NfL and t-tau, lying and standing DBP, and years of education (Fig. 1, bottom row). Notably, eight variables—minimum, maximum, mean, and standard deviation of t-tau; minimum and mean NfL; and lying and standing DBP—were consistently selected across all three methods. ML performance varied across algorithms and feature sets (Table 2). Models using longitudinal biomarker summaries (Model 1) consistently outperformed those using only baseline variables (Model 2), with AUCs ranging from 0.640 to 0.763 vs 0.465 to 0.560, respectively. The XGBoost model using RF-selected variables (Model 4) achieved the highest AUC (0.806; 95% CI, 0.663–0.949) and the best overall performance, with accuracy of 0.730, sensitivity of 0.875, specificity of 0.690, F1 score of 0.583, and a Brier score of 0.140. The LightGBM model using time-varying biomarker summaries (Model 1) performed well (AUC = 0.763; 95% CI, 0.598–0.928), as did both LightGBM and XGBoost models using SHAPvIC-selected variables (Model 5; AUC = 0.698 for both). These models showed comparable sensitivity and specificity to the top-performing XGBoost model, though with slightly lower precision and calibration.

Fig. 2 shows calibration results for Model 4, based on top predictors selected via RF. XGBoost and LightGBM demonstrated the best calibration, with mean absolute errors <0.05 and close alignment to the 45-degree reference line, indicating well-calibrated predictions. The RF model was reasonably calibrated but showed deviation in lower predicted probabilities. In contrast, KNN and NN models were poorly calibrated, underestimating risk in high-risk individuals and overestimating in low-risk cases. In the best-performing model—XGBoost using RF-selected variables—key predictors included years of education, lying and standing DBP, four summary statistics (minimum, maximum, mean, and standard deviation) for both NfL and t-tau, and p-tau181 levels. SHAP visualizations showed that elevated and variable t-tau levels strongly influenced high-risk classification. Supine and upright DBP ≥90 mmHg also contributed substantially. While NfL features were associated with cognitive decline, they were less frequently among the top three predictors. Overall, incorporating longitudinal biomarker summaries—especially dynamic t-tau features—improved predictive performance and enabled more parsimonious models suitable for clinical application. Discussion In this prospective study of early PD, integrating longitudinal blood biomarkers—particularly t-tau and NfL—significantly enhanced cognitive decline prediction using ML. The XGBoost model with RF-selected features achieved the best performance (AUC = 0.806), a substantial improvement over the baseline-only model (AUC = 0.560). Across algorithms, dynamic changes in t-tau and DBP emerged as the most consistent predictors. The consistent identification of t-tau features highlights tau pathology's role in PD-related cognitive decline. Notably, t-tau variability was a strong predictor, indicating temporal fluctuations may reflect meaningful biological processes like axonal damage or inflammation. Although CSF biomarkers are informative, blood-based assays offer minimal invasiveness and increasing reliability with technologies like Simoa. Our results support using serial plasma t-tau as a prognostic tool in PD, enabling longitudinal monitoring of neurodegeneration. Patients with rising or fluctuating t-tau levels could be candidates for further assessment or early intervention. The inclusion of NfL as a predictive biomarker also corroborates prior evidence of its value [48, 49]. NfL reflects axonal injury and has been associated with faster motor and cognitive progression in PD [35, 50-55]. However, its predictive strength in our study was somewhat less robust than that of t-tau, suggesting that while NfL may capture broader neurodegenerative processes, tau-specific mechanisms may be more intimately tied to cognitive trajectories. These distinctions could be important in future therapeutic trials, where stratifying patients by biomarker phenotype may help tailor interventions or identify treatment responders. Beyond molecular biomarkers, our study reinforces the prognostic importance of DBP—both in lying and standing positions—as a consistent clinical predictor of cognitive decline. The association of elevated DBP with two-fold increased risk has significant clinical implications [56-58]. Autonomic dysfunction is common in PD and can lead to labile blood pressure patterns, including supine hypertension and orthostatic hypotension. These fluctuations may impair cerebral autoregulation, reduce perfusion to vulnerable brain regions, and accelerate neurodegeneration. Current PD guidelines focus on motor symptoms, but our findings support routine blood pressure monitoring to identify vascular risk and guide early intervention. Importantly, blood pressure represents a modifiable risk factor. Interventions such as midodrine, fludrocortisone, or domperidone may be used to address hypotension, while antihypertensives including ACE inhibitors or calcium channel blockers could be considered for elevated supine DBP, ideally under close monitoring to avoid worsening orthostatic symptoms. In patients with high DBP and fluctuating tau profiles, a multidisciplinary approach involving neurology, cardiology, and internal medicine may be warranted. Incorporating vascular health into PD management may not only reduce cognitive risk but also improve cardiovascular outcomes in this aging population. Another key finding was the protective effect of education, supporting the cognitive reserve hypothesis. Participants with ≥10 years of formal education had a 58% lower odds of cognitive decline than those with less education. While not modifiable retrospectively, educational attainment may aid in risk stratification. Individuals with limited education could benefit from closer cognitive monitoring, targeted interventions, and referral to neuropsychology. They may also be prioritized for emerging strategies to preserve cognitive function, including lifestyle modification, cognitive training, and digital therapeutics. Our results also point to the potential value of deploying ML-based prediction tools in clinical workflows. By integrating time-varying biomarker data, clinical measures, and demographic factors, ML algorithms can generate individualized risk scores that support early identification and proactive care. For instance, a PD patient with high DBP and rising t-tau levels could be flagged for cognitive rehabilitation or clinical trial referral, while a low-risk individual might focus on motor symptom management. These tools could be embedded in electronic health records (EHRs), providing decision support to clinicians and improving consistency in care delivery. Furthermore, ML-derived insights could enhance patient-provider communication, allowing neurologists to frame prognosis in more concrete terms, support advance care planning, and tailor surveillance strategies. In clinical trial design, predictive models like ours can support enrichment strategies to boost statistical power and reduce sample sizes. Given the heterogeneity of PD progression, selecting high-risk individuals based on longitudinal tau and DBP dynamics may enhance trial efficiency and increase the likelihood of detecting treatment effects. This approach is particularly valuable for emerging disease-modifying therapies, such as anti-tau and anti-synuclein agents, where early intervention is key. Our findings also align with broader evidence suggesting that mixed pathology is common in PD, particularly in those with cognitive impairment [59, 60]. While PD is defined pathologically by Lewy bodies composed of α-synuclein, many patients with dementia show concurrent tau and amyloid pathology on autopsy or PET imaging [61, 62]. The observed importance of tau dynamics in our study supports this concept and may prompt reconsideration of PD as a disease spectrum rather than a single pathology [63]. This perspective opens the door to cross-disease therapeutic strategies and biomarker-guided personalization of care, particularly for those who meet overlapping criteria for PD, dementia with Lewy bodies, or AD [64, 65]. From a mechanistic standpoint, the interplay between vascular dysregulation and tau-driven neurodegeneration is particularly noteworthy. Chronic cerebrovascular dysfunction can disrupt glymphatic clearance of toxic proteins, promote blood-brain barrier breakdown, and create a permissive environment for tau aggregation. Conversely, tau pathology may exacerbate vascular reactivity deficits through endothelial dysfunction or oxidative stress. This bidirectional model suggests that targeting both pathways may offer synergistic benefits. For example, interventions aimed at reducing vascular stiffness or enhancing neurovascular coupling might complement disease-modifying therapies targeting tau aggregation or phosphorylation. Despite its strengths, this study has limitations. While we used rigorous internal validation, external validation in independent cohorts is needed to confirm generalizability. The primarily Asian composition of the PALS cohort may limit applicability to other populations. Biomarkers were measured at only three time points; more frequent sampling could enhance trajectory analysis. Finally, although we focused on interpretable features and avoided overfitting, future studies should assess whether adding biomarkers of synaptic dysfunction, neuroinflammation, or α-synuclein activity improves prediction. Future research should prioritize replication in multiethnic cohorts, integration of imaging biomarkers (e.g., tau PET, diffusion MRI), and development of practical risk calculators for clinical use. Cost-effectiveness studies will be essential to evaluate the feasibility of widespread biomarker monitoring. As high-sensitivity blood assays become more accessible, their implementation will be facilitated by advances in digital health, cloud analytics, and decentralized data sharing. Conclusions This study shows that integrating longitudinal biomarker dynamics, particularly t-tau, with ML significantly enhances prediction of cognitive decline in early PD. These findings support the use of regular biomarker monitoring, vascular risk management, and predictive tools to enable personalized care and improve trial efficiency—marking a key step toward precision neurology in PD.

With aging populations, its prevalence is expected to double by 2040, increasing burdens on healthcare systems and caregivers. Although PD is primarily defined by motor symptoms such as bradykinesia, rigidity, and tremor, non-motor features—particularly cognitive impairment—contribute significantly to morbidity [\u003cspan additionalcitationids=\"CR2 CR3\" citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e–\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e]. Cognitive decline affects up to 80% of patients, with many progressing from mild cognitive impairment (PD-MCI) to Parkinson’s disease dementia (PDD) within a few years of diagnosis [\u003cspan additionalcitationids=\"CR6 CR7 CR8 CR9\" citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e–\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e]. Cognitive deficits in PD have serious clinical and societal impacts, including reduced quality of life, loss of independence, and higher rates of institutionalization. Healthcare costs for patients with PDD are twice those without dementia, and caregivers face increased psychological and financial strain. Predicting cognitive decline remains challenging due to heterogeneous disease progression. Early identification of at-risk patients is crucial for timely intervention, counseling, and improving clinical trial design [\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e, \u003cspan additionalcitationids=\"CR12 CR13\" citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e–\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e].\u003c/p\u003e\u003cp\u003eCurrent prognostic tools poorly predict cognitive outcomes in PD. Clinical scales like the Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) focus on motor symptoms and offer limited insight into cognitive decline. While Cerebrospinal fluid (CSF) biomarkers and neuroimaging provide some prognostic value, they are invasive, costly, and impractical for routine use [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e, \u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e].

Participants were enrolled from specialist clinics in Singapore (2014–2018). Inclusion criteria were PD diagnosis within 1 year, symptom onset within 2 years, and meeting the National Institute of Neurological Disorders and Stroke criteria. Participants required at least six years of education. Exclusion criteria included comorbidities likely to confound outcomes or hinder follow-up (e.g., malignancy, unstable cardiovascular disease) [\u003cspan citationid=\"CR44\" class=\"CitationRef\"\u003e44\u003c/span\u003e, \u003cspan citationid=\"CR45\" class=\"CitationRef\"\u003e45\u003c/span\u003e]. Of 214 participants recruited, 193 completed baseline assessments and had at least three years of cognitive follow-up, comprising the final analytic cohort. Informed consent was obtained; the study was approved by the Singapore Health Services Centralized Institutional Review Board.\u003c/p\u003e\u003cp\u003e Participants underwent detailed annual evaluations over five years, including clinical, cognitive, and laboratory assessments. Cognitive performance was measured using the Montreal Cognitive Assessment (MoCA). Venous blood samples were collected at baseline, year 3, and year 5. Primary biomarkers—NfL and t-tau—were quantified using ultra-sensitive single-molecule array (Simoa) assays. For these biomarkers, four summary features (minimum, maximum, mean, and standard deviation) were computed across time points to capture both levels and variability. Additional baseline biomarkers included suppression of tumorigenicity 2 (ST2), apolipoprotein E (APOE) genotype, p-tau181, and alpha-synuclein gene promoter repeat length (REP1). The primary outcome was cognitive decline, defined as either a ≥ 1-point annual decrease in MoCA score or a ≥ 1-point drop sustained across two consecutive years during the five-year follow-up. This threshold was selected to reflect subtle but clinically meaningful cognitive changes. Baseline demographic characteristics included age, sex, body mass index (BMI), years of education, smoking history, alcohol use, and consumption of coffee and tea. Clinical features comprised Hoehn and Yahr stage (HY), baseline MoCA score, MDS-UPDRS Part III score, systolic and diastolic blood pressure (SBP and DBP) measured in both lying and standing positions, and comorbidities including hypertension, diabetes mellitus, hypertension and hyperlipidemia.\u003c/p\u003e\u003ch2\u003eStatistical Analysis\u003c/h2\u003e\u003cp\u003eMissing data were addressed using a random forest (RF)–based imputation method [\u003cspan citationid=\"CR46\" class=\"CitationRef\"\u003e46\u003c/span\u003e]. All continuous variables were examined for clinical interpretability, and when appropriate, were dichotomized using clinically relevant thresholds. In the absence of established cutoffs, the Youden index was used to derive optimal cut-points from ROC curves to maximize sensitivity and specificity [\u003cspan citationid=\"CR47\" class=\"CitationRef\"\u003e47\u003c/span\u003e]. Descriptive statistics were used to summarize all variables. Continuous variables were presented as mean (standard deviation) or median (interquartile range), and categorical variables as counts and percentages. Associations between individual predictors and cognitive decline were assessed using univariate logistic regression, reporting odds ratios (ORs) with 95% confidence intervals (CIs).\u003c/p\u003e\u003cp\u003eTo identify the most informative predictors, we applied three complementary variable selection methods. First, RF importance scores were used to rank variables by mean decrease in Gini impurity, retaining only those above the average score. Second, the Shapley Variable Importance Cloud (SHAPvIC) method quantified each variable’s contribution using SHAP values; variables with 95% prediction intervals entirely above zero were selected. Third, we applied gain-based feature importance from Extreme Gradient Boosting (XGBoost), keeping variables with scores above the mean. This triangulated approach enhanced both statistical robustness and consistency across methods. For predictive modeling, we trained five supervised ML algorithms: RF, neural network (NN), k-nearest neighbors (KNN), XGBoost, and Light Gradient Boosting Machine (LightGBM). Each algorithm was evaluated across seven different feature sets: time-varying biomarkers alone; baseline variables alone; a combination of both; and subsets derived from each of the three variable selection strategies (including a reduced version of SHAPvIC for parsimony). The dataset was randomly split (80:20) into training and test sets, stratified by cognitive decline status. Hyperparameters were optimized via five-fold cross-validation on the training set. For RF, we tuned the number of trees and number of predictors considered at each split. For XGBoost and LightGBM, we optimized learning rate (0.01–0.1), number of boosting rounds (50–500), maximum tree depth (3–7), and L1/L2 regularization terms (range: 0–1). NN models varied in hidden layer size (1–5) and applied weight decay (0–0.1), while the optimal number of neighbors (k = 1–10) was selected for KNN models. Model performance was assessed on the held-out test set using multiple metrics. Discrimination was evaluated via AUC with 95% CIs from 1,000 bootstrap resamples. Additional metrics included sensitivity, specificity, accuracy, precision, recall, F1 score, and Brier score. The F1 score, the harmonic mean of precision and recall, balances false positives and negatives. The Brier score quantifies the accuracy of probabilistic predictions. Sensitivity and specificity were calculated at the optimal threshold via Youden’s index. Calibration was assessed using decile-based plots comparing observed and predicted event rates across 10 bins. All analyses were performed using R version 4.2.2 (R Foundation for Statistical Computing, Vienna, Austria).

The RF approach identified twelve variables, including years of education, lying and standing DBP, and four summary statistics (minimum, maximum, mean, and standard deviation) for both NfL and t-tau, along with baseline p-tau181 levels (Fig.\u0026nbsp;1, top row, left). The ShapleyVIC method selected fourteen predictors, which included t-tau (minimum, maximum, mean, and standard deviation), NfL (minimum and mean), as well as baseline MoCA score, hyperlipidemia, coffee and alcohol consumption, lying and standing DBP, p-tau181, and gender (Fig.\u0026nbsp;1, top row, right). The XGBoost-based method identified eleven key features, including the full set of summary metrics for both NfL and t-tau, lying and standing DBP, and years of education (Fig.\u0026nbsp;1, bottom row). Notably, eight variables\u0026mdash;minimum, maximum, mean, and standard deviation of t-tau; minimum and mean NfL; and lying and standing DBP\u0026mdash;were consistently selected across all three methods.\u003c/p\u003e\u003cp\u003eML performance varied across algorithms and feature sets (Table\u0026nbsp;2). Models using longitudinal biomarker summaries (Model 1) consistently outperformed those using only baseline variables (Model 2), with AUCs ranging from 0.640 to 0.763 vs 0.465 to 0.560, respectively.\u003c/p\u003e\u003cp\u003eThe XGBoost model using RF-selected variables (Model 4) achieved the highest AUC (0.806; 95% CI, 0.663\u0026ndash;0.949) and the best overall performance, with accuracy of 0.730, sensitivity of 0.875, specificity of 0.690, F1 score of 0.583, and a Brier score of 0.140. The LightGBM model using time-varying biomarker summaries (Model 1) performed well (AUC\u0026thinsp;=\u0026thinsp;0.763; 95% CI, 0.598\u0026ndash;0.928), as did both LightGBM and XGBoost models using SHAPvIC-selected variables (Model 5; AUC\u0026thinsp;=\u0026thinsp;0.698 for both). These models showed comparable sensitivity and specificity to the top-performing XGBoost model, though with slightly lower precision and calibration. Notably, the reduced SHAPvIC subset (Model 6), comprising six variables, achieved the highest specificity (0.862; 95% CI, 0.683\u0026ndash;0.961) with XGBoost, highlighting the utility of parsimonious models in clinical prediction.\u003cdiv class=\"BlockQuote\"\u003e\u003cp\u003e\u003cb\u003eTable\u0026nbsp;2.

XGBoost and LightGBM demonstrated the best calibration, with mean absolute errors \u0026lt;0.05 and close alignment to the 45-degree reference line, indicating well-calibrated predictions. The RF model was reasonably calibrated but showed deviation in lower predicted probabilities. In contrast, KNN and NN models were poorly calibrated, underestimating risk in high-risk individuals and overestimating in low-risk cases.\u003c/p\u003e\n\u003cp\u003eIn the best-performing model\u0026mdash;XGBoost using RF-selected variables\u0026mdash;key predictors included years of education, lying and standing DBP, four summary statistics (minimum, maximum, mean, and standard deviation) for both NfL and t-tau, and p-tau181 levels. SHAP visualizations showed that elevated and variable t-tau levels strongly influenced high-risk classification. Supine and upright DBP \u0026ge;90 mmHg also contributed substantially. While NfL features were associated with cognitive decline, they were less frequently among the top three predictors. Overall, incorporating longitudinal biomarker summaries\u0026mdash;especially dynamic t-tau features\u0026mdash;improved predictive performance and enabled more parsimonious models suitable for clinical application.\u003c/p\u003e"},{"header":"Discussion","content":"\u003cp\u003eIn this prospective study of early PD, integrating longitudinal blood biomarkers\u0026mdash;particularly t-tau and NfL\u0026mdash;significantly enhanced cognitive decline prediction using ML. The XGBoost model with RF-selected features achieved the best performance (AUC = 0.806), a substantial improvement over the baseline-only model (AUC = 0.560). Across algorithms, dynamic changes in t-tau and DBP emerged as the most consistent predictors. The consistent identification of t-tau features highlights tau pathology\u0026apos;s role in PD-related cognitive decline. Notably, t-tau variability was a strong predictor, indicating temporal fluctuations may reflect meaningful biological processes like axonal damage or inflammation.\u003c/p\u003e\n\u003cp\u003eAlthough CSF biomarkers are informative, blood-based assays offer minimal invasiveness and increasing reliability with technologies like Simoa. Our results support using serial plasma t-tau as a prognostic tool in PD, enabling longitudinal monitoring of neurodegeneration. Patients with rising or fluctuating t-tau levels could be candidates for further assessment or early intervention.\u003c/p\u003e\n\u003cp\u003eThe inclusion of NfL as a predictive biomarker also corroborates prior evidence of its value [48, 49]. NfL reflects axonal injury and has been associated with faster motor and cognitive progression in PD \u0026nbsp;[35, 50-55]. However, its predictive strength in our study was somewhat less robust than that of t-tau, suggesting that while NfL may capture broader neurodegenerative processes, tau-specific mechanisms may be more intimately tied to cognitive trajectories. These distinctions could be important in future therapeutic trials, where stratifying patients by biomarker phenotype may help tailor interventions or identify treatment responders.\u003c/p\u003e\n\u003cp\u003eBeyond molecular biomarkers, our study reinforces the prognostic importance of DBP\u0026mdash;both in lying and standing positions\u0026mdash;as a consistent clinical predictor of cognitive decline. The association of elevated DBP with two-fold increased risk has significant clinical implications [56-58]. Autonomic dysfunction is common in PD and can lead to labile blood pressure patterns, including supine hypertension and orthostatic hypotension. These fluctuations may impair cerebral autoregulation, reduce perfusion to vulnerable brain regions, and accelerate neurodegeneration. Current PD guidelines focus on motor symptoms, but our findings support routine blood pressure monitoring to identify vascular risk and guide early intervention.\u003c/p\u003e\n\u003cp\u003eImportantly, blood pressure represents a modifiable risk factor. Interventions such as midodrine, fludrocortisone, or domperidone may be used to address hypotension, while antihypertensives including ACE inhibitors or calcium channel blockers could be considered for elevated supine DBP, ideally under close monitoring to avoid worsening orthostatic symptoms. In patients with high DBP and fluctuating tau profiles, a multidisciplinary approach involving neurology, cardiology, and internal medicine may be warranted. Incorporating vascular health into PD management may not only reduce cognitive risk but also improve cardiovascular outcomes in this aging population.\u003c/p\u003e\n\u003cp\u003eAnother key finding was the protective effect of education, supporting the cognitive reserve hypothesis. Participants with \u0026ge;10 years of formal education had a 58% lower odds of cognitive decline than those with less education. While not modifiable retrospectively, educational attainment may aid in risk stratification. Individuals with limited education could benefit from closer cognitive monitoring, targeted interventions, and referral to neuropsychology. They may also be prioritized for emerging strategies to preserve cognitive function, including lifestyle modification, cognitive training, and digital therapeutics.\u003c/p\u003e\n\u003cp\u003eOur results also point to the potential value of deploying ML-based prediction tools in clinical workflows. By integrating time-varying biomarker data, clinical measures, and demographic factors, ML algorithms can generate individualized risk scores that support early identification and proactive care. For instance, a PD patient with high DBP and rising t-tau levels could be flagged for cognitive rehabilitation or clinical trial referral, while a low-risk individual might focus on motor symptom management. These tools could be embedded in electronic health records (EHRs), providing decision support to clinicians and improving consistency in care delivery. Furthermore, ML-derived insights could enhance patient-provider communication, allowing neurologists to frame prognosis in more concrete terms, support advance care planning, and tailor surveillance strategies.\u003c/p\u003e\n\u003cp\u003eIn clinical trial design, predictive models like ours can support enrichment strategies to boost statistical power and reduce sample sizes. Given the heterogeneity of PD progression, selecting high-risk individuals based on longitudinal tau and DBP dynamics may enhance trial efficiency and increase the likelihood of detecting treatment effects. This approach is particularly valuable for emerging disease-modifying therapies, such as anti-tau and anti-synuclein agents, where early intervention is key.\u003c/p\u003e\n\u003cp\u003eOur findings also align with broader evidence suggesting that mixed pathology is common in PD, particularly in those with cognitive impairment [59, 60]. While PD is defined pathologically by Lewy bodies composed of \u0026alpha;-synuclein, many patients with dementia show concurrent tau and amyloid pathology on autopsy or PET imaging [61, 62]. The observed importance of tau dynamics in our study supports this concept and may prompt reconsideration of PD as a disease spectrum rather than a single pathology [63]. This perspective opens the door to cross-disease therapeutic strategies and biomarker-guided personalization of care, particularly for those who meet overlapping criteria for PD, dementia with Lewy bodies, or AD [64, 65].\u003c/p\u003e\n\u003cp\u003eFrom a mechanistic standpoint, the interplay between vascular dysregulation and tau-driven neurodegeneration is particularly noteworthy. Chronic cerebrovascular dysfunction can disrupt glymphatic clearance of toxic proteins, promote blood-brain barrier breakdown, and create a permissive environment for tau aggregation. Conversely, tau pathology may exacerbate vascular reactivity deficits through endothelial dysfunction or oxidative stress. This bidirectional model suggests that targeting both pathways may offer synergistic benefits. For example, interventions aimed at reducing vascular stiffness or enhancing neurovascular coupling might complement disease-modifying therapies targeting tau aggregation or phosphorylation.\u003c/p\u003e\n\u003cp\u003eDespite its strengths, this study has limitations. While we used rigorous internal validation, external validation in independent cohorts is needed to confirm generalizability. The primarily Asian composition of the PALS cohort may limit applicability to other populations. Biomarkers were measured at only three time points; more frequent sampling could enhance trajectory analysis. Finally, although we focused on interpretable features and avoided overfitting, future studies should assess whether adding biomarkers of synaptic dysfunction, neuroinflammation, or \u0026alpha;-synuclein activity improves prediction. Future research should prioritize replication in multiethnic cohorts, integration of imaging biomarkers (e.g., tau PET, diffusion MRI), and development of practical risk calculators for clinical use. Cost-effectiveness studies will be essential to evaluate the feasibility of widespread biomarker monitoring. As high-sensitivity blood assays become more accessible, their implementation will be facilitated by advances in digital health, cloud analytics, and decentralized data sharing.\u003c/p\u003e"},{"header":"Conclusions","content":"\u003cp\u003eThis study shows that integrating longitudinal biomarker dynamics, particularly t-tau, with ML significantly enhances prediction of cognitive decline in early PD.

Using data from 193 participants in the Early Parkinson\u0026rsquo;s Disease Longitudinal Singapore (PALS) cohort, we evaluated whether longitudinal blood biomarkers\u0026mdash;neurofilament light chain (NfL) and total tau (t-tau)\u0026mdash;could improve prediction of cognitive decline, defined as a one-point annual or sustained two-year drop in Montreal Cognitive Assessment scores. We applied three variable selection methods and five machine learning models across seven feature sets. Overall, 23% of participants experienced cognitive decline over five years. The XGBoost model trained on Random Forest\u0026ndash;selected variables achieved the highest performance (AUC\u0026thinsp;=\u0026thinsp;0.806), a substantial improvement over the baseline-only model (AUC\u0026thinsp;=\u0026thinsp;0.560). Key predictors included diastolic blood pressure and summaries of t-tau and NfL.
