Absence seizures are brief episodes of staring.
During the seizure, awareness and responsiveness are impaired. People who have them usually don't realize when they've had one. There is no warning before a seizure, and the person is completely alert immediately afterward.Simple absence seizures are just stares. Many absence seizures are considered complex absence seizures, which means that they include a change in muscle activity. The most common movements are eye blinks.
Tonic Clonic seizures;
This type is what most people think of when they hear the word "seizure." An older term for them is "grand mal." As implied by the name, they combine the characteristics of tonic seizures and clonic seizures. The tonic phase comes first: All the muscles stiffen. Air being forced past the vocal cords causes a cry or groan. The person loses consciousness and falls to the floor. The tongue or cheek may be bitten, so bloody saliva may come from the mouth. The person may turn a bit blue in the face. After the tonic phase comes the clonic phase: The arms and usually the legs begin to jerk rapidly and rhythmically, bending and relaxing at the elbows, hips, and knees. After a few minutes, the jerking slows and stops. Bladder or bowel control sometimes is lost as the body relaxes. Consciousness returns slowly, and the person may be drowsy, confused, agitated, or depressed.
Myoclonic seizures are brief, shock-like jerks of a muscle or a group of muscles. "Myo" means muscle and "clonus" means rapidly alternating contraction and relaxation—jerking or twitching—of a muscle.
Even people without epilepsy can experience myoclonus in hiccups or in a sudden jerk that may wake you up as you're just falling asleep. These things are normal.
Simple partial seizures;
They are remarkably different from person to person, depending on the part of the brain where they begin.
Doctors often divide simple partial seizures into categories depending on the type of symptoms the person experiences:
Motor seizures:These cause a change in muscle activity. For example, a person may have abnormal movements such as jerking of a finger or stiffening of part of the body.
Sensory seizures:These cause changes in any one of the senses. People with sensory seizures may smell or taste things that aren't there; hear clicking, ringing, or a person's voice when there is no actual sound; or feel a sensation of "pins and needles" or numbness. Seizures may even be painful for some patients. They may feel as if they are floating or spinning in space.
Autonomic seizures:These cause changes in the part of the nervous system that automatically controls bodily functions. These common seizures may include strange or unpleasant sensations in the stomach, chest, or head; changes in the heart rate or breathing; sweating; or goose bumps.
Psychic seizures:These seizures change how people think, feel, or experience things.hey may have problems with memory, garbled speech, an inability to find the right word, or trouble understanding spoken or written language. They may suddenly feel emotions like fear, depression, or happiness with no outside reason.
Complex partial seizures;
These seizures usually start in a small area of the temporal lobe or frontal lobe of the brain. They quickly involve other areas of the brain that affect alertness and awareness. So even though the person's eyes are open and they may make movements that seem to have a purpose, in reality "nobody's home." If the symptoms are subtle, other people may think the person is just daydreaming.
Some people can have seizures of this kind without realizing that anything has happened. Because the seizure can wipe out memories of events just before or after it, however, memory lapses can be a problem.
