Sometimes she sees a dog in her kitchen and at other times she sees a stranger in her garden, both of which no one else can see. She also reports a lack of motivation to do daily tasks for the past week. Three years ago, she was diagnosed with Parkinson disease and was started on levodopa and carbidopa. Her younger brother has schizophrenia. The patient also takes levothyroxine for hypothyroidism. She used to drink a bottle of wine every day, but she stopped drinking alcohol 2 months ago. Neurologic examination shows a mild resting tremor of the hands and bradykinesia. Her thought process is organized and logical. Which of the following is the most likely underlying cause of this patients symptoms?? A: Adverse effect of medication, B: Alcohol withdrawal, C: Schizophrenia, D: Major depressive disorder, E: Poorly controlled hypothyroidism,  <response>: This is a clinical vignette describing a 72-year-old woman with visual hallucinations, apathy, and a history of Parkinsons disease treated with levodopacarbidopa. The question asks to identify the most likely underlying cause of her symptoms. Key points from the vignette:- Visual hallucinations - seeing things that are not there- Lack of motivationapathy - History of Parkinsons disease on levodopacarbidopa- Family history of schizophrenia- History of alcohol use disorder, quit drinking 2 months ago- Mild parkinsonian signs on exam The choices include medication side effects, alcohol withdrawal, schizophrenia, depression, and hypothyroidism. Visual hallucinations can occur with dopamine agonists used to treat Parkinsons disease. Apathy can also be a side effect. Her symptoms began after starting Parkinsons medications, making this a likely cause. Alcohol withdrawal is less likely 2 months after quitting drinking. Schizophrenia is possible given the family history, but visual hallucinations are more characteristic of Lewy body dementia seen in Parkinsons disease. Depression could cause apathy but not hallucinations. Hypothyroidism is unlikely to cause her symptoms.A: Adverse effect of medication
