Imaging Approaches to the Epileptic Patient
Seizures are the result of excessive and abnormal electrical discharges from the cortical neurons. Epilepsy, the condition of spontaneously recurring seizures, is quite common, affecting approximately 0.4–1% of the population. The epilepsy syndromes can be categorized into localized, or partial, and generalized. Generalized seizures originate from both cerebral hemispheres simultaneously. Partial seizures are generated from a localized area of the brain. These can be further divided into complex partial, with loss of consciousness, and simple partial, without loss of consciousness. Partial seizures can secondarily generalize by spread from one area to another. Seizure classification has therapeutic and prognostic values that help in the care of patients with epilepsy.
