Neurons or nerve cells throughout our central nervous system choreograph our daily function by transmitting electrical and chemical signals to control our every move and thought. In the vast majority of people, these signals and transmissions work in a well-patterned manner, resulting in appropriate movements. For the almost 3 million US adults and children living with epilepsy, these same nerve cells fire their signals abnormally, which results in a seizure. Seizures are sudden, abnormal increases in electrical impulse from nerve cells of the brain.

It is important to remember that not all seizures indicate epilepsy. This is especially true if it is the person’s first seizure or if the seizure is associated with a high-fever illness in children. Many more people may suffer from NES or non-epileptic seizures from various causes.

Epilepsy is often associated only with strobe lighting; however, this is just one of many triggers that can induce a seizure. Each patient suffering from epilepsy may have a slightly different manifestation of the disorder. Some will be more severe than others, as seizures may be caused by different parts of the brain. This is why epilepsy is known as a spectrum disorder, meaning there are many different manifestations and permutations of the disorder.

Epilepsy is typically a lifelong disorder that can only be managed, not cured. However, some patients that receive effective epilepsy treatment may never have another seizure. We simply don’t know enough about the disorder to do more than offer the most advanced and effective treatments currently available.

Who Gets Epilepsy? What are the Causes?

Young and old, male and female, healthy and unhealthy can all develop epilepsy. In fact, in over half of those suffering from epilepsy, there is no known origin. For the other half of patients, the onset of epilepsy can be traced back to one or more of the following causes:

• Genetics
• Brain trauma
• Infections and inflammations of the brain
• Heart attacks or strokes
• Alzheimer’s disease
• Alcohol abuse

Types of Epilepsy

Because of the breadth of epilepsy as a disorder, it is impossible to group every case under one umbrella term. Different forms of epilepsy are named after the region of the brain in which they originate or by the symptoms they cause. There are about 40 different types of epilepsy and patients may suffer from one or more types. Just a few of the many types of epilepsy follow:

Temporal Lobe Epilepsy is a very common form of epilepsy that typically begins when patients are in their younger years through their teens. These seizures will often affect emotions and senses of smell and taste. Patients may suffer from impaired consciousness as they enter a temporary trance-like state. Those suffering from temporal lobe epilepsy may have difficulty with learning or memory as the hippocampus of the brain is commonly affected by these seizures.

Frontal Lobe Epilepsy is characterized by a focal seizure and often occurs while the patient is sleeping. Patients typically have some loss of awareness and may experience uncontrolled movements anywhere in the body, from their extremities to facial movements.

Absence epilepsy is thought to be a hereditary form of epilepsy that typically begins at a young age and runs in families. Symptoms are typically more mild and can include “staring off into space” or jerking movements that have no specific purpose. Most children with this form of epilepsy will no longer have symptoms after puberty, however some will continue to experience symptoms or develop new seizures into adulthood.
