A Three reports of the successful use of ECT in the relief of GLT are cited in the ECT Database. Tics are seen in many emotional disorders in addition to GLT, including OCD and catatonia.
Tics are also a manifestation of catatonia.
A 58-year old woman with recurrent depressive illnesses developed prominent tics of coprolalia as a feature of catatonia. Periodically she was also mute, rigid, staring, and negativistic, with coprolalia most prominent when she was disturbed. ECT was prescribed for the depressive mood disorder and catatonia. After the second bilateral ECT, the tics disappeared, and after the fifth ECT, all signs of catatonia, including tics and coprolalia, disappeared.
