Catatonia With Thrombotic

T OT HEEDITOR: We report a case of new-onset catatonia in a patient with a documented history of thrombotic thrombocytopenic purpura but no psychiatric history. This case raises the possibility of a correlation between catatonia and thrombotic thrombocytopenic purpura. The case also highlights the increased sensitivity in patients with thrombotic thrombocytopenic purpura to neuroleptic-induced catatonia.
