Update on Catatonia
August 01, 2006
Since its initial description by Kahlbaum (1828-1899) over a century ago, catatonia has been associated with psychiatric, neurologic, and medical disorders. Contemporary authors view catatonia as a syndrome of motor signs in association with disorders of mood, behavior, or thought. Some motor features are classic but infrequent (eg, echopraxia, waxy flexibility) while others are common in psychiatric patients (eg, agitation, withdrawal), becoming significant because of their duration and severity.
