Abstract

Katherine R Goettsche, Kim Jihye and Dimitry Francois

Catatonia occurs in a range of psychiatric, neurologic, medical, and toxic conditions. Several neurobiological abnormalities predispose individuals to catatonia. Here we present a case of a 57-year-old man with a major depressive disorder with psychotic features and catatonia, whose evaluation was notable for positive serum antibodies against N-type calcium channel, without evidence for malignancy.
