In TS Epilepsy is one of the most common features of Tuberous Sclerosis. It is often the problem which leads to the diagnosis of Tuberous Sclerosis being made. Epilepsy occurs in most but not all people with Tuberous Sclerosis.
Epilepsy is the tendency to have recurrent, unprovoked epileptic seizures.
Unprovoked means that the epileptic seizures occur out of the blue by themselves and have not been provoked by something such as a low blood sugar, flashing lights or an acute brain injury. There are many different types of epileptic seizure and different patterns of epilepsy. The thing that is common to all epileptic seizures is that they are caused by a sudden and excessive burst of the electrical activity of the nerve cells of the brain. These nerve cells send their messages to each other and to other parts of the body by small electrical signals. If this abnormal electrical activity spreads to a large enough group of the nerve cells then it will result in an epileptic seizure.
