An electroencephalograph (EEG) of partial seizure
Partial seizures do not affect the whole brain and are often caused by localised cerebral lesions. In this type of seizure, the abnormal electrical discharge in the brain is localised in the temporal, frontal or occipital site. These discharges produce mild symptoms, with no loss of consciousness. The incidence partial seizures increases with age.
