Epilepsy is a neurological condition where a person can experience seizures that are a result of activity in the brain. It can develop at any time following a traumatic brain injury but most commonly does so within a year following the event. The possibility of this happening depends on various factors, including the type of injury and the location and extent of the damage.
Epileptic seizures occur when the normal activity of the brain is disrupted suddenly. This disrupted or epileptic activity may be localised to one particular area of the brain or it may involve all parts of the brain. The seizure that is witnessed as an outward sign of this activity will vary depending on the part or parts of the brain in which the activity is occurring.
Seizures can occur without warning and vary in length. However, most last for a specific time related to each person and do stop naturally. Many people with epilepsy take antiepileptic drugs. Although such drugs do not cure epilepsy, they do stop the seizures from occurring in up to 80 per cent of cases and may be prescribed as a preventative measure following a severe brain injury.
Seizures are most often classified according to where the seizure activity begins and fall into three main types: partial, secondarily-generalised and generalised.
