The department of Clinical Neurophysiology at Jaslok Hospital
has two computerized State-of–Art DIGITAL Video EEG
machines for evaluation of epilepsy. Two rooms have been
specially allocated for EEG recording. This ensures privacy
and a quiet atmosphere, which is especially required for
a true sleep recording.
One of the EEG machines in the Department is portable
equipment that can easily be carried to the patient’s
bedside or to the ICU or the operating theatre.
EEG records electrical activity from the surface of the
brain.
THE PROCEDURE: EEG is a painless non-invasive
test lasting for about 40- 60 minutes. Several small electrodes
are attached all over the scalp and the signals picked up
by the electrodes are amplified and recorded by the digital
EEG machine. Special activation methods are usually used
during the recording e.g. over breathing, flash / photic
stimulation, and sleep deprivation. There are no side effects
of this examination.
INDICATIONS FOR AN EEG:

hypoxia/ ischemia.
-
Newborns who have had minor fits or
convulsions.
-
Babies with encephalitis and/or meningitis.
-
Repetitive, unprovoked seizures; often
termed as fits or attacks
-
Metabolic encephalopathies
-
Sleep–related disorders e.g.
night terrors, night walking, unusual leg and body movements
in sleep
-
Children with degenerative diseases
such as SSPE
-
Persons with epileptic seizures.
-
Metabolic encephalopathies, e.g. hepatic,
toxic, uremia, etc.
-
Confusion and altered awareness following
head injury.
-
