Impulse Control Disorders in Parkinson’s Disease
Impulse Control Disorders in Parkinson’s Disease
This chapter focuses on explaining impulse control disorders (ICD) in Parkinson’s disease (PD). A PD patient suffers from ICD when he or she loses control over impulses associated with the performance of certain tasks that are impulsive in nature. The impaired agentic self system resulting from PD aggravates ICD and leads to impulsive decisions on sexual activities, financial matters, and gambling. Reduced doses of certain medicines and enhanced dopaminergic activity cause ICD in certain PD patients. ICDs and the compulsive use of dopaminergic medicines in PD patients are mainly observed in younger males afflicted with the disease. Younger patients are vulnerable to symptoms of involuntary movement and unstable motor activities, and are administered certain medications to control these disorders. Regular and compulsive use of such medications have severe side effects and result in ICDs in a few PD patients.
