Title : Epilepsy & Seizure disorders
Abstract:
Epilepsy is a brain disorder characterized by repeated seizures. A seizure is defined as a sudden alteration of behavior to the brain due to a temporary change in the electrical functioning. Usually, the brain continuously generates tiny electrical impulses in an orderly pattern, these impulses travel along neurons (the network of nerve cells in the brain) and throughout the whole body via chemical messengers called neurotransmitters.
Epilepsy causes the brain’s electrical rhythms to become imbalanced, resulting in recurrent seizures.
The four main types of seizures, based on their origin and nature, are focal seizures, generalized seizures, focal and generalized seizures, and unknown onset seizures. Focal seizures start in one part of the brain, generalized seizures affect the entire brain, and some seizures can be a combination of both. Unknown onset seizures are those where the origin cannot be determined.
