Question: What Is Catatonia?
Answer: Catatonia is a condition characterized by psychomotor disturbance, an interruption of normal movement. Catatonic features can occur with major depression, bipolar disorder I and II, schizoaffective disorder and schizophrenia. In some cases, catatonia may also be an extreme side effect of a medication.

Possible Presentations:

  • Stupor - lack of response to external stimuli, e.g., no response to being spoken to or prodded
  • Catalepsy - muscular rigidity, so that the limbs remain in whatever position they are placed.
  • Excessive motor activity with no purpose
  • Extreme negativism - resistance to movement or instruction
  • Mutism - being unable or unwilling to speak
  • Inappropriate postures and grimacing
  • Echolalia - parrot-like repetition of a word or phrase just spoken by another person
  • Echopraxia - repetitive imitation of the movements of another person

Complications caused by this condition:

  • Malnutrition
  • Exhaustion
  • Self-inflicted injury
