[Trypanosomiasis: determination of groups of patients from clinical and electroencephalographic data]

Data constituted from clinical and waking electroencephalographic signs in 104 patients at meningoencephalitis stage of trypanosomiasis were treated by way of a correspondence analysis in order to determine clinical profiles. Three profiles were identified. The first one, encountered in patients with minor clinical disturbances and slightly modified waking electroencephalographic patterns is suggestive of a cerebral involvement stage onset. The second one, observed in patients with vigilance disturbances, behavioral and motor impairment, and highly abnormal EEG tracing is indicative of a more severe encephalitis stage. The third one, obvious in patients with EEG sharp waves organized in a more or less recurring fashion and accompanied by epileptic seizures is consistent with an acute cerebromeningitis.
