10. Behavioral Changes – The Unpredictable Element of PDD
Behavioral changes in PDD, though challenging, are a crucial symptom of the disorder. These can include agitation, impulse control disorders, and even psychosis in severe cases. These changes may be related to disease progression, cognitive impairment, and, in some instances, side effects of medications used in Parkinson’s disease.
Agitation in PDD can present as restlessness, frustration, or emotional outbursts. Impulse control disorders can involve behaviors such as compulsive shopping, gambling, or eating. In more severe cases, psychosis can occur, characterized by delusions or paranoid thoughts.
These behavioral changes can have profound effects on the lives of both the individuals with PDD and their caregivers. They can lead to social isolation, family conflict, and caregiver stress. (10)
