Dopamine agonists (DA) are a type of Parkinson's medication that can cause hypersexuality. The word hypersexuality refers to heightened sexual arousal, interest, and behavior than what a person had previously experienced, and causes enough trouble to disrupt a person's life as well as the lives of those around them. Hypersexuality is considered a rare side effect of using DA for Parkinson's treatment, representing only 3.5% of the total users.
