Epilepsy

When nerve cells in the brain fire electrical impulses at a rate of up to four times higher than normal, this causes a sort of electrical storm in the brain, known as a seizure. A pattern of repeated seizures is referred to as epilepsy. Known causes include head injuries, brain tumors, lead poisoning, maldevelopment of the brain, genetic and infectious illnesses. But in fully half of cases, no cause can be found. Medication controls seizures for the majority of patients.

Because epilepsy is caused by abnormal activity in the brain, seizures can affect any process your brain coordinates. Seizure signs and symptoms may include:

Temporary confusion
A staring spell
Uncontrollable jerking movements of the arms and legs
Loss of consciousness or awareness
Psychic symptoms such as fear, anxiety or deja vu
Symptoms vary depending on the type of seizure. In most cases, a person with epilepsy will tend to have the same type of seizure each time, so the symptoms will be similar from episode to episode.

Doctors generally classify seizures as either focal or generalized, based on how the abnormal brain activity begins.

Heredity plays a role in some types of epilepsy. In the general population, there’s a 1 percent chance of developing epilepsy before 20 years of age. If you have a parent whose epilepsy is linked to genetics, that increases your risk to 2 to 5 percent.
