Abstract

Mild cognitive impairment (MCI) in Parkinson's disease (PD) includes deficits in theory of mind (ToM). However, associations between ToM and caregiver burden and distress are still unclear. The objective of this pilot study was to preliminarily explore the relation between ToM and caregiver burden and distress in a sample of PD-MCI patients. Twelve PD-MCI patients were evaluated on a ToM task (Faux Pas), whereas their caregivers were assessed on caregiver burden (Zarit Burden Interview-12 items) and distress (Neuropsychiatric Inventory-Distress). Cognitive ToM was significantly associated with caregiver distress, but caregiver burden was associated with the severity of patient psychiatric symptoms.
