What is Epilepsy?

Epilepsy is a neurological disorder where the nerve cells in your brain are disturbed, causing seizures which can vary from unnoticeable to convulsing fits. Epilepsy is a spectrum condition with a wide range of seizure types and control varying from person-to-person. A seizure occurs when brain cells that control body functions generate abnormal or excessive electrical discharges.

Doctors generally classify seizures as either focal or generalized, based on how the abnormal brain activity begins. When seizures result from abnormal activity in just one area of the brain, they are called focal or partial seizures. Seizures that involve all areas of the brain are called generalized seizures.

Epileptic seizures are characterized by the intensity of the event: petit mal, partial (focus) and grand mal.

Types of Epilepsy

Petit malis known as an absence seizure with mild reactions such as eyes blinking rapidly or the person staring into space.

Partial (focus) seizures cause confusion and failure to communicate, nausea, abdominal pain and muscle contractions lasting for a few minutes.

Grand mal is the most severe, causing a person to lose consciousness, fall to the ground and become jerky, followed by disorientation and fatigue.

Diagnosing epilepsy may include brain imaging, blood work and electroencephalogram (EEG). EEGs are conducted by putting electrodes on the patient’s scalp to record brain wave activity. Other imaging tests that may be used are CT or MRI scans that help our team determine if there are any lesions in the brain that may be causing the seizures.

What are the Risk Factors for Epilepsy?

Risk factors can make a person more likely to have seizures and epilepsy. Some risk factors can include:

  • Babies who are born small for their age.
  • Babies who have seizures in the first month of life.
  • Bleeding into the brain.
  • Abnormal blood vessels in the brain.
  • Serious injury or lack of oxygen to the brain.

  • 3 million people in the United States have epilepsy.
  • 1 in 26 people in the United States will develop epilepsy at some point in their lifetime.
  • A third of people with epilepsy live with uncontrollable seizures because no available treatment works for them.
  • There are around 150,000 new cases of epilepsy in the United States each year.
