Everyday functioning of people with Parkinson's disease and impairments in executive function: a qualitative investigation.

Purpose: Executive function is the key area of cognitive impairment in Parkinson's disease. This study investigated how cognitive difficulties impact on everyday life of people with Parkinson's disease and their carers, and whether they explicitly mention executive-type difficulties.

Methods: Semistructured interviews with 11 people with Parkinson's disease and six carers were analyzed thematically.
