title: Idiopathic basal ganglia calcification presenting as schizophrenia-like psychosis and obsessive-compulsive symptoms: A case report.
abstract: Idiopathic basal ganglia calcification (IBGC) is a rare neurodegenerative disorder characterized by the deposition of calcium in the brain and variable combinations of movement disorders, gait impairment and neuropsychiatric symptoms. Few reports have described psychiatric manifestations as early symptoms of IBGC. The present study reports the case of a middle-aged man with schizophrenia-like psychosis and obsessive-compulsive symptoms as the first manifestations of IBGC. The response of the patient to olanzapine and fluoxetine suggests that low-dose olanzapine is effective and should be increased cautiously to avoid worsening parkinsonism and that fluoxetine is an effective drug for the treatment of obsessive-compulsive symptoms in IBGC.
