A seizure can be caused by various factors, including an injury or a medical condition. Any time a person has an abnormality in the blood vessels in the brain, which could be caused by an injury or by a condition that compromises the flow of blood to the brain, a seizure can result. Some seizures are relatively mild and are called petit mall seizures. A massive seizure, which lasts longer than a mild seizure and is more pronounced, is called a grand mall seizure.

Seizures are sometimes referred to as convulsions. They temporarily alter the function of the brain, according to Neurology.health-cares.net. The alteration occurs because something has short-circuited the electrical activity in the brain cells. This abnormal brain activity results in an involuntary change in the body’s movement and function as well as a person's awareness and behaviour. A seizure occurs when the cells in the brain misfire and prompt an uncontrolled, sudden surge of electrical activity in the brain, according to Epilepsy.com. When a seizure originates from an area in the right half of the brain, which controls the left half of the body, jerking motions will occurs on the left side and vice versa.
A seizure can be brief, lasting only a few seconds, or it can last much longer. If a person is having a grand mall or tonic-clonic seizure he may fall to the ground, experience body rigidity and jerking muscles, cry out and then lose consciousness.
Someone who is having a complex partial seizure may appear dazed and confused and can’t respond to questions or direction. This kind of seizure, a petit mall seizure, can happen unnoticed by others and may consist of the individual staring into space and blinking rapidly. A complex partial seizure can last half a minute up to two minutes. When the seizure is over the individual who experienced it will be confused and tired and may not completely come around for a few hours. This type of seizure can wipe out memories of events that occurred prior to the seizure. The outward symptoms of this type of seizure are very subtle. Other people may not realise that it’s happening and may think the person is day dreaming, according to Epilepsy.com. The seizing person’s eyes will remain open and they may move as if with purpose but the fact is that “nobody’s home” at the moment the seizure is occurring. A complex partial seizures starts in the temporary lobe or frontal lobe of the brain and can involve the parts of the brain that control awareness and alertness.
Petit mall, or a mild seizure, is sometimes referred to as an absence seizure. An absence seizure is described as that which temporarily disturbs brain function, and is the result of abnormal electrical activity in the brain. Such seizures are abrupt and don’t last long. Individuals under the age of 20 are the most common victims of absence seizures.
The reason the petit mall is referred to as an absence seizure is because the victim will be absent for several seconds and may stop speaking in mid sentence or stop walking or whatever they may be doing at the time. Some children have hundreds of these seizures in a day. The seizures can be perceived as the child not paying attention but that is not the case. There is no memory of the seizure afterward.
