Differential diagnosis of tardive dyskinesia: an overview
RP Granacher Jr
The author states that most psychiatrists should be able easily to
recognize tardive dyskinesia. However, this disorder is a subset of a large
variety of abnormal involuntary movements, some of which may resemble
tardive dyskinesia. Others have serious implications if they are
misdiagnosed as tardive dyskinesia. The author describes the characteristic
features of a wide variety of abnormal involuntary movements, including
parkinsonism, the dystonias, choreas and choreoathetosis, tremors, tics,
stereotypies and mannerisms, oral- facial dyskinesias, and disorders with
varied or complex manifestations. He emphasizes the differential diagnosis
of tardive dyskinesia.
