EEG: The Results Are Here To See |

An EEG stands for an Electroencephalogram. Difficult to pronounce and
still not considered particularly valuable for the diagnosis of headaches,
except for distinguishing complicated migraines from complex partial
seizures. It can be used to find out if there is
actually some kind of a malfunction in the brain.
An EEG measures
the electrical signals of the brain by using a set of electrodes placed
on the scalp. These signals are then transmitted to a machine called the
polygraph which records these signals.
It is
important that any medications that you are taking prior to an EEG
should be discussed with your doctor. Also since, the electrodes will be
placed on the head, it is essential to wash your hair a day prior to the
test. And then do not use any hair cream, spray or oil.
During
the test, about 20 electrodes are placed on the scalp. Anti-convulsant
medications can be started soon after the EEG is over.
Though the
EEG does not pinpoint the exact problem in adults, it can, however, be
used to find out cerebral abnormalities in children.
