title: Unrecognized catatonia as a cause for delayed weaning in Intensive Care Unit.
abstract: The cause of altered sensorium in critical care settings includes metabolic derangements, drug and toxin overdose, central nervous system infections, neurodegenerative disorders, vascular events, hypo-perfusion states, and septic encephalopathy. Here, we present a case of an elderly woman who presented to us with altered sensorium with respiratory failure requiring mechanical ventilation. Her metabolic parameters, imaging, and cerebrospinal fluid study were all normal despite that she continued to remain in altered sensorium and had an unrecognized behavioral state that delayed her weaning.
