Carer burden in apathy and impulse control disorders in Parkinson's disease

The neuropsychiatric complications of Parkinson's disease (PD), which include behaviour disturbances such as apathy and the impulse control disorders (ICDs), may have a significant effect on patients with PD and their carers. The contribution of these behaviour disorders to carer burden is less understood. Therefore, the aim of this study was to explore the relationship that apathy and ICDs have with carer burden.
