Of 12 consecutive patients with bipolar mood disorders satisfying DSM-
III criteria, six were discovered to have five or more psychomotor
epileptic symptoms. All of the six had olfactory hallucinations,
metamorphopsias, and multiple deja vu or mystical experiences. Each of them
responded to lithium carbonate and had a first-degree relative with a
bipolar disorder. The authors suggest that psychomotor symptoms may be more
prevalent in bipolar patients than has hitherto been recognized.
