Reactions 1704, p225 - 2 Jun 2018 Psychosis: case report A 73-year-old woman developed psychosis during treatment with levodopa/carbidopa [route and dosage not stated and time to reaction onset not clearly stated]. The woman had a two year history of parkinsonism and dementia which was treated with levodopa/carbidopa. She was admitted with catatonia/unresponsiveness. A month before admission, she was using a walker to get food in a buffet line. A few days later, she started experiencing hallucinations and depression. She was treated with citalopram and quetiapine. On next morning, she woke up but was unable to move. She was transferred to the psychiatric unit and was discharged to a skilled nursing facility on primavanserin and olanzapine treatment after 8 days. Despite this, she continued to experience "unresponsive" or "trance- like" episodes every other day. Extensive workup including autoimmune studies revealed presence of anti-TPO was positive. She underwent IV immune globulin treatment for concerns of Hashimoto’s encephalopathy, but without any improvement. Stopping the rivastigmine and antipsychotics improved cognition. The woman’s levodopa/carbidopa treatment was restarted as the cessation worsened parkinsonism features. Author comment: "The most important cause of psychosis in [Parkinson’s disease] is probably the dopamine agonists used to treat it." Ahmad S.
