Agitation is one of the diagnostic features of catatonia in the DSM IV clas
sification, but permanent forms of agitated catatonia have occasionally bee
n described. We report the case of a 43-year-old man who had already suffer
ed from undifferentiated schizophrenia for 7 years, and in whom we diagnose
d agitated catatonia. While our patient was being treated with a neurolepti
c during a second episode of paranoia, a state of agitation was observed wh
ich persisted for a further 8 months. During this period, he was treated wi
th several different neuroleptics and benzodiazepines, either alone or in a
ssociation, without any improvement. No organic cause was found. He was the
n transferred to our electroconvulsive therapy (ECT) unit, with a diagnosis
of schizophrenic agitation resistant to drug therapy. ECT was begun, and h
e was only given droperidol in case of agitation and alimemazine for insomn
ia, neither of which had any effect. In view of his persistent agitation wi
thout any purpose, echolalia and echopraxia, stereotyped movements with man
nerisms and marked mimicking and grimacing, we diagnosed him as having agit
ated catatonia. After the fourth session of ECT, we decided to stop all tre
atment and gave him lorazepam at a dose of 12.5 mg daily. Twenty-four hours
later, all symptoms of agitation had disappeared. In our opinion, permanen
t catatonic agitation is not rare. In our case, the neuroleptic treatment m
aintained and may even have worsened the symptomatology. Lorazepam can be u
sed as a therapeutic test for this type of agitation, especially if it does
not respond to neuroleptics. This also allows the patient to be sedated ra
pidly and effectively, thus preventing him from injuring himself further.
