There are several different types of seizures and its symptoms depend on the type of seizure. In some seizures, people can only shake hands slightly without loss of consciousness whereas in some other type of seizure, the person may become unconscious and experience violent shaking of the entire body.
Seizures can be classified as:
Symptoms of generalised seizures
Generalised seizure causes loss of consciousness and the entire body is affected by it. There are six main types of generalised seizure the symptoms of which depend on the type of seizure. Generalised tonic-clonic seizure is the most common and dramatic type of generalised seizure.
Symptoms of tonic-clonic seizure: In this type of seizure, the person loses consciousness and the body becomes stiff initially and with the arms and legs starting to twitch in the second phase. The initial phase of stiffness is called the "tonic" phase of seizure and lasts 30 to 60 seconds. The second phase of violent jerking is called the "clonic" phase. In this type of seizure, the person loses consciousness and may even pass urine or motion. In most cases, the seizure lasts between one and three minutes, but may often last longer.
Symptoms of absence seizure: The person loses consciousness or awareness for up to 20 seconds. This may happen hundreds of times in a day and occurs most often in children. The child has no memory of the seizure and is therefore, not aware of the seizure.
Symptoms of myoclonic jerks: The arms, legs or upper body may jerk or twitch suddenly as if the person has been given an electric shock. They usually last for a very short time (a fraction of a second). The person is conscious during this time.
Symptoms of Clonic seizure: In this seizure also the person experiences twitching as myoclonic jerks, which are repetitive and rhythmic and involve both sides of the body. The seizures last for up to two minutes and the person may lose consciousness.
Symptoms of Atonic seizure: In this type of seizure, all the muscles relax gradually or suddenly. There is a chance that the person may fall.
Tonic seizure: In this type of seizure, all the muscles become stiff suddenly making the person lose balance and fall over.
Symptoms of partial seizures
Partial seizures can be classified as:
Symptoms suggestive of a simple partial seizure include:
Symptoms of a complex partial seizure include:
In this type of seizure, the person loses consciousness (awareness) and can’t remember what happened during the seizure.
