Othello syndrome and dopamine dysregulation syndrome

Abstract

Othello syndrome is a paranoid delusional jealousy characterised by false absolute certainty of the infidelity of a partner, leading to preoccupation with a partner's sexual unfaithfulness based on unfounded evidence. Here, we present a case of Othello syndrome comorbid to dopamine dsyregulation syndrome in a patient suffering from juvenile Parkinson's disease. The case investigates the relationship between compulsive levodopa use and delusional jealousy, the serious consequences of these conditions and the difficulty in patient management.
