Epilepsy is a disorder of the central nervous system, specifically the brain.
In simple terms, our nervous system is a communications network that controls
every thought, emotion, impression, memory, and movement, essentially defining
who we are. Nerves throughout the body function like telephone lines, enabling
the brain to communicate with every part of the body via electrical signals. In
epilepsy disorder characterized by transient but recurrent disturbances of brain
function that may or may not be associated with impairment or loss of
consciousness and abnormal movements or behavior.Close the brain's electrical
rhythms have a tendency to become imbalanced, resulting in recurrent
seizures.
The brain is an extraordinarily complex organ. When it comes to understanding
epilepsy, there are several concepts about the brain you'll need to learn.
The first is that the brain works on electricity. Normally, the brain
continuously generates tiny electrical impulses in an orderly pattern. These
impulses travel along the network of nerve cells, called neurons, in the brain
and throughout the whole body via chemical messengers called neurotransmitters.
A seizure sudden, excessive discharge of nervous-system electrical activity that
usually causes a change in behavior.Closeoccurs when the brain's nerve cells
misfire and generate a sudden, uncontrolled surge of electrical activity in the
brain.
Another concept important to epilepsy is that different areas of the brain
control different functions.
If seizures arise from a specific area of the brain, then the initial
symptoms of the seizure often reflect the functions of that area. The right half
of the brain controls the left side of the body, and the left half of the brain
controls the right side of the body. So if a seizure starts from the right side
of the brain, in the area that controls movement in the thumb, then the seizure
may begin with jerking of the left thumb or hand.
