title: Consultation Dilemma Catatonia in a Patient with Prior TBI: MentaI or Medical Disorder?
abstract: Mr. R, a 27 year old Hispanic male with history of traumatic brain injury (TBI) over ten years prior but no psychiatric history, presents to the psychiatric consultation service with recent onset of mutism, psychotic behavior and new diagnosis of epilepsy. The differential diagnosis is broad and includes both medical and psychiatric causes: post-ictal state, non-convulsive status epilepticus, delirium due to metabolic conditions, drugs, catatonia, conversion disorder, major depression with psychotic features, new onset schizophrenia or a combination of these possible diagnoses. We explore different medical causes that can present with symptoms of catatonia, as it is crucial to rule out a possible treatable medical cause.
