Core Tip
Core Tip: Cases of delusional parasitosis during medication, such as dopamine agonists, in Parkinson’s disease have been reported. However, this case report shows that delusional parasitosis occurred before the diagnosis of Parkinson’s disease. In addition, unlike in other treatments for delusional disorders, the patient’s delusions improved quickly. After delusional parasitosis improved, the motor symptoms of Parkinson’s disease were observed, and Parkinson’s disease was diagnosed. The sudden onset of delusional parasitosis in elderly without a psychiatric history could be associated with the premotor or non-motor symptoms of Parkinson’s disease. Therefore, an evaluation of Parkinson’s disease should be considered for elderly with delusional parasitosis.
