Significance of abnormal brain perfusion in catatonia: a case report.
In this case study, the significance of perfusion abnormalities in catatonia is examined.. Recurrent catatonic symptoms are frequently observed in psychiatric disorders, but the predictors of relapse of the catatonic symptoms remain unknown. Perfusion abnormalities have been reported during catatonic states; however, little is known about brain functioning of catatonic patients during remission.. A catatonic patient was evaluated by clinical interview, behavioral examination, and functional neuroimaging (single photon emission computed tomography) to determine diagnosis and brain perfusion.. The patient exhibited persistent hypoperfusion of the basal ganglia even after achieving symptomatic remission.. These findings predict a secondary cause and may predict a chronic course.

ECT treatment and cerebral perfusion in Catatonia.
A 40-yr-old woman with a diagnosis of schizoaffective disorder developed catatonia in the context of a depressive episode. A dramatic decrease in perfusion of the inferior frontal, posterior temporal and parietal lobes bilaterally and in posterior frontal lobes corresponding to the motor cortices was noted on the 99mTc-HMPAO SPECT scan obtained in the acute phase. The most dramatic decreases compared to normal control subjects were observed in the left parietal and left motor cortices. The patient was treated with a five-treatment course of electroconvulsive therapy (ECT), which resulted in a complete resolution of catatonia and some resolution of her symptoms of depression. The repeat HMPAO-SPECT scan showed improved perfusion in all areas. The most dramatic increases occurred in the left parietal and left motor cortices. Decreased perfusion in motor and parietal cortices could be state-specific to catatonia. Thus, SPECT imaging may be a useful method for monitoring catatonia treatment response.
