B

Specifiers

Catatonia associated with another mental disorder: Occurs in the context of mood, schizophrenia spectrum, or other psychiatric conditions.
Catatonic disorder due to another medical condition: Attributable to an underlying medical or neurological illness.
Unspecified catatonia: Catatonic features present but the underlying condition is unclear.
With stupor: Predominant immobility and unresponsiveness.
With excitement: Marked excessive and purposeless motor activity.
Severity (Mild / Moderate / Severe): Based on number and intensity of catatonic signs and degree of functional compromise.

Documentation support

Consistent with [Catatonia] [specifier(s)]. During the current episode, there have been stupor; catalepsy; waxy flexibility; mutism; negativism; posturing; mannerisms; stereotypy; agitation not influenced by external stimuli; grimacing; echolalia; echopraxia, forming a pattern meeting the threshold of at least three catatonic symptoms. The presentation is further characterised by marked psychomotor disturbance that may occur in the context of a primary psychiatric disorder, a medical condition, or may be unspecified when the underlying cause is unclear. These symptoms have resulted in clinically significant impairment in functioning or require urgent medical/psychiatric intervention, and the disturbance is not better explained by delirium, substance/medication effects, or neurological conditions such as non-convulsive status epilepticus.
