Attentional dysfunction and the punding spectrum in Parkinson's disease.

ABSTRACT:

Background

Punding is a complication of Parkinson's disease (PD) treatment and stimulant abuse that features excessive preoccupation with repetitive and/or aimless behaviors. We hypothesized that cognitive impairment and functional limitations influence how punding behaviors manifest in PD.

Methods

We extracted data on punding, hobbyism, and cognition from the Parkinson's Progression Marker Initiative (PPMI). Punding and hobbyism were measured with the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease (QUIP) scale. We determined how cognition predicted punding and hobbyism behaviors-adjusting for levodopa dose, Hoehn & Yahr stage, disease duration, and age-using generalized estimating equation (GEE) logistic regression. Activities of daily living (ADL)
