An electroencephalogram (EEG) is a pioneering form of medical
test that helps detect the manifestation of any electrical activity inside your
brain. The test is conducted with the help of small, metal discs (aka
electrodes) fastened to your scalp. The cells which constitute your brain, remain
active every time and interconnect by sending and
receiving electrical impulses yet when you sleep. This activity is displayed in
the form of undulating lines and recorded on an EEG monitor.
Patients with epilepsy who come to our clinic in Punjabi Bagh
for treatment are recommended an EEG test for an initial examination. This test
is considered to be the primary means to detect and diagnose epilepsy.Even to
diagnose certain brain disorders, our diagnostic center offers a EEG Test in Punjabi Bagh.
What is the
significance of an EEG test?
The test mainly determines fluctuations in brain activity.
This is useful in identifying idiosyncratic brain disorder like epileptic
seizures. In addition, an EEG test can come of use to spot and treat the
following maladies.
·
Origination
and presence of a brain tumor
·
The
extent of damage done to the brain because of a head injury
·
Brain
impairment caused by various factors (encephalopathy)
·
Brain
inflammation (encephalitis)
·
The
inception of a stroke
·
A
disorder like sleep apnea
An EEG is also helpful to bring off the distinctive
confirmation of a brain death of patient reeling under a permanent coma or to
understand the accurate level of anesthesia for a patient undergoing a medically
induced coma.
Are there any risks
associated with an EEG test?
EEG is absolutely safe and pain-free. On certain occasions,
seizures are deliberately triggered during the test especially for people
struck down with epilepsy. However, proper medical care and precaution are
provided if needed.
How EEG is used to
diagnose Epilepsy?
Normal EEG
Your doctor may suggest performing an EEG to distinguish
brain abnormalities like epilepsy. A typical performance of a test for
EEG in Punjabi Bagh involves the recording of the brain’s innate
electrical activity by using electrodes attached to your scalp with a
paste-like substance or a cap.
In case you’re afflicted by epilepsy, it’s commonly observed
that your brain waves digress from following a normal pattern even when you
don’t have a seizure. When conducting an EEG, your doctor may scrutinize a
video recording of any seizure you may encounter while you're awake or asleep.
The recording empowers your doctor to gauge the exact type of seizures you're suffering
from and write off other co-occurring conditions.
Ambulatory EEG
Ideally, the test is carried out in a hospital or a doctor’s
clinic. But, you may also opt for an ambulatory EEG where you’re equipped with
the gear at home. This enables prolonged and persistent monitoring of seizures
outside of the hospital setting. It records brain activity over a course of a
few days which in turn which increases the chances of catching a seizure
activity.
High-density EEG
Here the electrodes are spaced more closely
(roughly half a centimeter apart) than in normal EEG. With this specialized
test, your doctor can exactly recognize the specific areas of your brain marked
by seizures.
