Catatonia is a neurological disorder classified as a psychomotor syndrome. The condition affects approximately 10% of patients with acute psychiatric conditions. Most people think of a catatonic state as a total lack of movement or brain activity. However, some people develop excited catatonia, which presents as agitation.
Experts define akinetic catatonia as the inability to move voluntarily, also known as akinesia. This type of catatonia also includes catalepsy, a coma-like state that includes body rigidity and loss of sensation, the inability or refusal to speak, and near-unconsciousness. Tests show that people with this type of catatonia exhibit less activity in the medial prefrontal cortex, which is responsible for social cognition.
