What is a Seizure?
A seizure is the result of a sudden burst of excess
electrical activity in the brain. This causes the
brainís messages to become temporarily halted or mixed
up. The type of seizure a person has depends on the
area of the brain where this activity occurs.
What is Epilepsy?
Epilepsy is currently defined as a tendency to have
recurrent seizures (sometimes called fits). A seizure
is caused by a sudden burst of excess electrical
activity in the brain, causing a temporary disruption
in the normal message passing between brain cells. This
disruption results in the brainís messages becoming
halted or mixed up. The brain is responsible for all
the functions of your body, so what you experience
during a seizure will depend on where in your brain the
epileptic activity begins and how widely and rapidly it
spreads. For this reason, there are many different
types of seizures and each person will experience
epilepsy in a way that is unique to them.
What is an EEG?
An EEG measures the electrical activity of the brain,
often referred to as brain waves.
How is the Test Done?
Your technologist will measure and mark your head with
a wax pen to find the precise places for several wired
metal disks (electrodes) to be attached to your head.
Each spot will be cleaned with a special
toothpaste-like substance and the electrodes will be
applied with a small amount of cream and then glued
with a medical-grade adhesive to hold them in
place. You will be made as comfortable as possible. The
wires are attached to a recording machine, which will
measure and record the electrical activity of your
brain. Video and audio recording will be collected
throughout the length of your study.
What Preparation is Needed?
- Freshly shampooed, dry hair with no hair spray,
braids, cream, or oil on your scalp is required.
- Please take all of your prescribed medications
