[Autochronometry in patients with focal epilepsy]

A study included 163 patients with focal cryptogenic and symptomatic forms of epilepsy and 47 sex- and age-matched controls. Disturbances of autochronometry in epileptic patients were studied with regard to character, duration, severity, seasonality of seizures and localization of pathological activity in EEG. The elongation of internal count of chronominutes and the ratio of individual chronominute to duration of daylight hours suggest either the approach of a seizure or the early post seizure period, the effect of the completed seizure. The right hemisphere lesion mostly impacts on the patient's perception of time making it longer.
