Epilepsy

Epilepsy: Introduction

Epilepsy is a neurological disorder in which the nerves in the brain communicate abnormally with each other. This results in a variety of types of recurring seizures. Epilepsy, also called a seizure disorder, is a common condition, affecting about three million people in the U.S., according to the Epilepsy Foundation.

Epilepsy occurs when a surge of electrical signals from one cluster of nerve cells, called neurons, temporarily overwhelm other neurons in the brain. This results in different types of epilepsy and a wide variety of symptoms, depending on the area of the brain affected and how much of the brain is affected.

The there are many types and sub types of epilepsy. These include grand mal seizures, petit mal seizures, simple partial seizures, and complex partial seizures. There is also a type of disorder called nonepileptic seizures, in which there is no abnormal brain activity.

The cause of epilepsy is unknown in about half of the people with the disorder. Identifiable causes include head injuries, dementia, and medical conditions and diseases that can cause brain damage, such as stroke, meningitis, cerebral palsy, and autism. There is also a hereditary link to some forms of epilepsy.

The symptoms of epilepsy vary greatly depending on the type of seizure, the individual person, and other factors. The symptom of jerking, convulsive seizures is not present in all types of epilepsy. Symptoms may also include loss of consciousness or unusual emotions, sensations, and behaviors. For more information on symptoms, refer to symptoms of epilepsy.

Epilepsy can lead to potentially serious complications, especially if it is left untreated or not managed consistently. These include injuries to the head and body from falling and convulsive seizure activity or from car accidents caused by a seizure. They also include drowning during a seizure. Epilepsy can also endanger a pregnancy and the mother as well. In addition, taking certain anti-epileptic medications may cause birth defects.

It is also not unusual for people with epilepsy to develop behavioral, emotional, or social problems due to the stigma associated with the conditions and the potentially embarrassing seizures.

Life threatening complications of epilepsy include status epilepticus, which increases the risk of permanent brain damage and death, and sudden unexplained death in epilepsy. Regular medical care and good control of seizures decrease the risk of developing these complications.

Making a diagnosis of epilepsy begins with taking a thorough personal and family medical history, including symptoms, and completing a physical and neurological examination. It also includes electroencephalogram, which examines the brain's electrical activity. Imaging test may include CT scan, MRI, and a lumbar puncture, which can help to identify or rule-out certain causes of epilepsy.

A diagnosis of some types of epilepsy can easily be missed or delayed because some symptoms are so subtle and can be easily overlooked. For information on misdiagnosis, refer to misdiagnosis of epilepsy.

There is no cure for epilepsy, although some children may grow out of some forms of the disorders. Most people with epilepsy can be effectively treated and enjoy living normal, productive lives. Treatment generally involves anti-epileptic medications, treating underlying conditions, and other therapies. For more information on treatment, refer to treatment of epilepsy. ...more »

Article Excerpts about Epilepsy

Epilepsy is a brain disorder in which clusters of nerve cells, or neurons, in the brain sometimes signal abnormally. In epilepsy, the normal pattern of neuronal activity becomes disturbed, causing strange sensations, emotions, and behavior or sometimes convulsions, muscle spasms, and loss of consciousness.
