![]() Formerly called secondarily generalised seizures, bilaterally convulsive seizures look like generalised tonic-clonic seizures. The person has no memory of what occurred during the complex partial phase of the seizure and often needs to sleep.įocal seizures becoming bilaterally convulsiveįocal seizures may progress due to spread of epileptic activity over one or both sides of the brain. Colour change, wetting and vomiting can occur in complex partial seizures.įollowing the seizure the person may remain confused for a prolonged period and may not be able to speak, see, or hear if these parts of the brain were involved. picking at clothing, picking up objects, chewing and swallowing, trying to stand or run, appearing afraid and struggling with restraint. Behaviour may be confused and they may exhibit automatic movements and behaviours e.g. Often the person's actions are clumsy and they will not respond normally to questions and commands. Behaviour during a complex partial seizure relates to the site of origin and spread of the seizure. Sometimes the person experiences a warning sensation or 'aura' before they lose awareness, essentially the simple partial phase of the seizure. Consciousness is lost and the person may appear dazed or unaware of their surroundings. ![]() Young children might have difficulty describing such sensations or may be frightened by these Focal seizures with impaired consciousnessįormerly called complex partial seizures, these arise in parts of the brain responsible for maintaining awareness, responsiveness and memory, typically parts of the temporal and frontal lobes. If sensory areas of the brain are involved the person may report experiences such as tingling or numbness, changes to what they see, hear or smell, or very unusual feelings that may be hard to describe. If the site of origin is the motor area of the brain, bodily movements may be abnormal (e.g. Consciousness is NOT impaired and the effects of the seizure relate to the part of the brain involved. Focal seizures without impaired consciousnessįormerly called simple partial seizures, these arise in parts of the brain not responsible for maintaining consciousness, typically the movement or sensory areas. The manifestations of a focal seizure depend on the part of the brain involved with the abnormal brain cell activity. Focal seizures used to be classified according to whether there is impairment of consciousness or not. Consciousness may or may not be impaired. Focal seizures used to be called partial seizures. Focal seizuresįocal seizures occur when the seizure arises in a localised part of the brain, usually on one side. There are many different types of seizures, but the major distinction that doctors try to make is between focal seizures, where the seizure arises in one part of the brain (usually on one side of the brain) and generalised seizures, where epileptic activity begins all over the brain (on both sides of the brain) simultaneously. What happens during a seizure reflects what parts of the brain are involved. This may create a temporary disturbance in the way the brain controls awareness and responsiveness and may cause unusual sensations or abnormal movements and postures. Seizures occur when there is a momentary 'imbalance' within electrical and chemical circuits in the brain, such that groups of brain cells act in an excessive fashion. Some epilepsies are due to an underlying abnormality of the brain structure or chemistry (formerly called symptomatic or secondary epilepsies). Genetic epilepsies (formerly called idiopathic or primary epilepsies) occur in an otherwise normal person and are due to a genetic predisposition to seizures. the site of seizure origin in the brain (generalised or focal seizures), or. ![]() Epilepsy can be thought of in terms of either: There are many different types of epilepsy, especially in infancy, childhood and adolescence. About 1 in 200 children (0.5%) have epilepsy, a neurological condition where children have a predisposition to recurrent, unprovoked seizures. 1 in 20 children (5%) will have a seizure of some form during childhood. Many people in the community have seizures.
