Abstract
OBJECTIVE: In addition to the classic motor symptoms of Parkinson's disease (PD), some patients suffer from a variety of non-motor symptoms. Cognitive deficits such as impairments to learning and memory have been noted in PD and pose a clinical concern. However, during early stages of the disease these deficits may be subtle and difficult to diagnose. To date, various methodologies have been used to identify and diagnose these impairments in PD; imaging studies, animal models, and computer simulated learning paradigms being the most popular. This review discusses the advantages and disadvantages of each method in studying cognitive deficits associated with PD. RESULTS: Imaging studies, including PET and magnetic resonance imaging scans, are useful when studying neural correlates of cognitive tasks. In contrast, toxin-induced and transgenic animal models are well suited for modelling physiological and behavioural conditions observed in humans. Computer simulated learning paradigms are used to analyze cognitive functioning when one engages in a cognitive task. CONCLUSION: Based on the level of impairment being studied (i.e. neurobiological, behavioural, cognitive basis, or a combination thereof), the use of these methodologies, individually or in conjunction, is imperative when establishing a complete model of PD and its effect on cognition.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
