: The conversion disorder (CD) or functional neurological symptom disorder is a diagnostic category used in some psychiatric classification systems, which often refers to the patients presenting with neurological symptoms. Parkinson’s disease (PD) essentially affects non-motor and motor functions. The chronic use of levodopa, which is the primary treatment in this regard, has been reported to cause complications such as the wearing-off phenomenon. This problem may also increase the disease symptoms, as well as the patients’ need to receive higher doses of the drug to remain symptom-free for a longer period. This case study aimed to describe a 47-year-old male patient with PD and psychotic features, the symptoms of which had progressed in a conversional setup relating to particular visitation times. According to the examinations, CD was the main problem, which simulated the features of PD.
