Evoked skin sympathetic potentials and electroencephalography in the differential diagnosis of temporal and frontal epilepsy

An aim of the study was to investigate indices of autonomous regulation (evoked skin sympathetic potentials--ESSP) and EEG in temporal and frontal epilepsy (TE and FE) before and after functional tests (physical, psychoemotional, hyperventilation). The study included 24 patients with TE, 20 patients...

Summary:An aim of the study was to investigate indices of autonomous regulation (evoked skin sympathetic potentials--ESSP) and EEG in temporal and frontal epilepsy (TE and FE) before and after functional tests (physical, psychoemotional, hyperventilation). The study included 24 patients with TE, 20 patients with FE and 20 healthy controls. The enhance of sympathetic component of reaction was seen in FE and that of parasympathetic component--in TE. The sympathetic response to physical load and hyperventilation was insufficient in both forms of epilepsy that manifested itself in the reduced reaction amplitude and its longer duration. In the psychoemotional test, the reduction of sympathetic reaction amplitude and its later development was more characteristic of TE compared to FE. In conclusion, resting ESSP is more significant for differential diagnosis of TE and FE while in the functional test only quantitative differences between these forms were observed.
