The Effects of Epilepsy on the Body
Epilepsy is a disorder of the brain that causes recurring seizures. According to Johns Hopkins Medicine, almost three million Americans are living with epilepsy. Epilepsy can be triggered by illness or injury, but most of the time, there is no known cause. Because it is a disorder of the central nervous system, effects can be felt throughout the body. Due to the unpredictability of seizures, there can also be a great emotional toll.
Central Nervous System
The brain is the central hub for all voluntary and involuntary movements in your body. Electrical activity running through nerve cells help your brain tell your body what to do. When abnormal signals interrupt the brain’s normal functioning, you can have a seizure. There are several different types of seizures.
Focal seizures, also called partial seizures, are when abnormal electrical functions happen on only one side of the brain. Some people feel an aura, or a feeling of euphoria or doom, right before having a seizure. Other pre-seizure symptoms include changes to sight, hearing, or smell perception.
In a simple focal seizure, symptoms depend on which area of the brain is involved. The seizure may be accompanied by nausea or sweating. A complex focal seizure happens in the temporal lobe, which affects memory and emotion. This type of seizure usually involves loss of consciousness or lack of awareness of what’s happening. Symptoms may include screaming, crying, laughing, or lip smacking. There’s usually a feeling of sleepiness following a complex focal seizure.
