Epilepsy is a brain disorder that causes a person to have seizures. Seizures occur due to the electrical signal in your brain is suddenly disrupted. This disruption can cause changes in your awareness, behavior, body movements, emotions or sensations.
A seizure can be referred to as an “electrical storm” that causes the brain to do things that the person does not intend to.
Epilepsy affects nearly 3 millions Americans and 50 millions people worldwide. It commonly diagnosed in childhood, especially during the first year. The rate of new cases gradually declines until about age 10 and then become stable. After age 60, the risk starts to increase again.
What Causes Epilepsy?
The causes of epilepsy can be divided into two major groups: Idiopathic epilepsy and Symptomatic epilepsy.
In this type of epilepsy, the cause is unknown. However, it is believed that the seizures are caused by a lack of certain group of chemicals that are used to regulate the electrical impulses in the brain. Over 50% of epilepsy cases in children are Idiopathic epilepsy.
In this type of epilepsy, the cause can be identified, including: Illness, infection, head injuries, brain tumor, stroke, development disability, low blood sugar, low oxygen levels, kidney failure, alcohol, and certain medications.
