[Dyskinesias in infections of the central nervous system].
Dyskinesia, here, is considered to be synonymous with abnormal involuntary movement (AIM). AIMs are recognized in various infections of the central nervous system, of which Creutzfeldt-Jakob disease (CJD) and subacute sclerosing panencephalitis (SSPE) are thought to be the most important. The two show myoclonus and other similar features in common except age of onset. The myoclonus is classified under the non-stimulus-sensitive and periodic one characterized by a long duration and a relationship to periodic synchronous discharge (PSD) in EEG. The rhythm is, however, somewhat different and quicker in CJD (0.5-2 Hz) than in SSPE (0.05-0.2 Hz). In the acquired immunodeficiency syndrome (AIDS), AIMs, including tremor, myoclonus and some others are also noted.
