Comorbidity of parkinsonism and schizophrenia in a patient treated with clozapine.
Clozapine is the least likely anti-psychotic to induce extrapyramidal symptoms (EPS). We present a surprising case of a woman schizophrenic patient treated with clozapine suffering from EPS. Single photon emission computed tomography (SPECT) revealed a low density of presynaptic dopamine transporters in our patient's brain. A comorbid diagnosis of Parkinson's disease in schizophrenia was confirmed in this way. This helped us to find a proper therapeutic strategy for our patient.
