Focal seizures are diagnosed when the history, clinical presentation, and EEG findings support the localization of abnormal electrical neuronal discharges to one hemisphere of the brain. There are two major types of seizure: partial and generalized. If you observe postictal behavior or symptoms that are not typical for that person, get immediate medical help. The change in salt concentration conducts the impulse from one end of the nerve cell to the other. Make sure the area around their body is clear of objects that could hurt them. The person loses consciousness right from the beginning of the seizure. Do not insert anything in the mouth. It may also have a localizing value.

A seizure often has three distinct phases: aura, ictus, and postictal state. The first phase involves alterations in smell, taste, visual perception. The phases of seizures are: aura, ictus, and postictal.

What is a Seizure? Tonic-clonic seizures, formerly known as grand mal seizures, comprise two stages: a tonic phase and a clonic phase.

Tonic-clonic seizure: The classic type of epileptic seizure consisting of two phases to a tonic-clonic seizure -- the tonic phase and the clonic phase. In the tonic. A generalized tonic–clonic seizure, commonly known as a grand mal seizure or GTCS, is a type A tonic–clonic seizure comprises three phases: the tonic phase, clonic phase and postictal phase.
Tonic phase This phase is longer than the tonic phase with the total ictal period usually lasting no longer than 1 min. Skeletal.
Todd paresis may take up to 1 to 2 days for resolution.
The postictal period occurs after the active phase of seizure and is characterized by confusion, altered mental status, and somnolence.
Tonic, clonic and tonicclonic seizures
Sometimes, though, the slower activity occurs in both the ictal and postictal phases, making it difficult to distinguish between the phases on EEG. Jerking movements affect the face, arms and legs, becoming intense and rapid. The postictal phase can last for seconds, minutes, hours, and sometimes even days. Time interval required for return to baseline of the background rhythm on electroencephalogram after recorded electrographic seizures.

There are two broad categories of seizures; generalized and focal. If the person inadvertently bites their tongue or cheek, blood may be visible in the saliva. A retrospective study showed that the average time for EEG to return to baseline was minutes, with a maximum of minutes in adults.
