apathy in Parkinson's disease

Apathy in Parkinson's disease refers to a lack of interest, motivation, or enthusiasm, often affecting a person's ability to engage in activities they once enjoyed. This may manifest as reduced emotional expression, withdrawal from social interactions, or neglecting daily tasks. Unlike depression, which involves sadness, apathy is characterized by a sense of indifference or lack of initiative. It arises from changes in brain chemistry and function caused by Parkinson's, impacting areas involved in motivation and reward. Understanding apathy is essential for providing appropriate support and treatment for individuals with Parkinson's disease.
