Description
This dataset contains anonymised data from 103 individuals diagnosed with Parkinson’s Disease (PD), collected as part of a remote study investigating the relationships between cognitive functioning, emotion regulation strategies, and mental health outcomes. Data include demographic and clinical variables (e.g., age, gender, ethnicity, education, age of diagnosis, illness duration, levodopa equivalent daily dose, motor and non-motor aspects of daily living, and global cognition; performance-based cognitive tasks (Trail Making Test, Digit Span, Go/No-Go), self-reported functional cognitive impairment, and validated questionnaires assessing anxiety, depression, mental wellbeing and both cognitive and behavioural emotion regulation strategies. Data were collected via video call and online survey platforms. The dataset has been fully de-identified and stored in .csv format. It may be of interest to researchers studying cognition-emotion interactions, executive functioning, or non-motor symptoms in PD.
