Significance of abnormal brain perfusion in catatonia: a case report
1Department of Psychiatry and Behavioral Sciences, Finch University of Health Sciences, The Chicago Medical School, Illinois 60064, USA.
Objective:
In this case study, the significance of perfusion abnormalities in catatonia is examined.
Background:
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.
Method:
A catatonic patient was evaluated by clinical interview, behavioral examination, and functional neuroimaging (single photon emission computed tomography) to determine diagnosis and brain perfusion.
Results:
The patient exhibited persistent hypoperfusion of the basal ganglia even after achieving symptomatic remission.
Conclusions:
These findings predict a secondary cause and may predict a chronic course.
