Significance of abnormal brain perfusion in catatonia: A case report

Objective: In this case study, the significance of perfusion abnormalities in catatonia is examined. Background: Recurrent catatonic symptoms are freq uently observed in psychiatric disorders, but the predictors of relapse of the catatonic symptoms remain unknown. Perfusion abnormalities have been re ported during catatonic states: however, little is known about brain functi oning of catatonic patients during remission. Method: A catatonic patient w as evaluated by clinical interview. behavioral examination, and functional neuroimaging (single photon emission computed tomography) to determine diag nosis and brain perfusion. Results: The patient exhibited persistent hypope rfusion of the basal ganglia even after achieving symptomatic remission. Co nclusions: These findings predict a secondary cause and may predict a chron ic course.
