Catatonia in elderly psychiatric inpatients is not always associated with intense anxiety: Factor analysis and correlation with psychopathology.

Catatonic patients experienced more anxiety and hyperactivity. A three-factor solution provided best fit for catatonic symptoms. Patients with mania scored highest on Excitement, patients with depression on Inhibition, and patients with schizophrenia on Parakinetic. The main finding in this study was a positive moderate correlation between the Hamilton psychic score and the Inhibition factor score, meaning that not every catatonic dimension is associated to intense anxiety.
