Partial seizures

Partial seizures are also called focal seizures. The initial clinical and electroencephalographic changes suggest that neurons in a certain part of the cerebral hemisphere are activated first, and then a synchronized rapid discharge occurs, which quickly moves to the surrounding normal brain area. Diffusion produces a series of electrophysiological and neurochemical changes, until the neuron's energy is depleted and the metabolism is reduced, the onset is terminated automatically. According to whether the seizure process is accompanied by a disturbance of consciousness, it is divided into simple partial seizures (unconscious disturbances during the seizure) and complex partial seizures (with different degrees of conscious disturbance).
