What Is Catatonia?
Catatonia is a neuropsychiatric condition marked by significant changes in movement, behaviour, and responsiveness. A person may become extremely still, mute, or unable to initiate voluntary actions, or they may show excessive, purposeless movement. Catatonia can occur in the context of mental health conditions such as schizophrenia, bipolar disorder, or severe depression, as well as medical or neurological illnesses.
