- Electro Encephalography (EEG): both conventional and digital
- Polysomnography (Sleep Lab): It is one of the most advanced
practical instruments in the field of sleep disorder today. The
sleep trace machine is a complete Polysomngography lab. It can
record physiological data during sleep and is used for diagnosing
sleep and other related disorders as sleep apnea and snoring.
- Nerve conduction studies and electromyography (EMG): To
diagnose nerve and muscle disorders (numbness, weakness, nerve
Carrying out the procedure
- EEG takes about 1 hour
- EEG and Video EEG are completely safe and painless
- The patient will be positioned on a padded bed or table, or in
a comfortable chair
- The technician will start by rubbing the scalp
- He will then make some measurements using a tape and may put
some marks using a marker pen
- He will then fix the electrodes to the scalp to measure the
electrical activity in various parts of the brain, a nurse or EEG
technician will attach 16 to 20 electrodes to the scalp. The brain
generates electrical impulses that these electrodes will pick up.
To improve the conduction of these impulses to the electrodes, a
gel will be applied to them. Then temporary glue will be used to
attach them to the skin. No pain will be involved.
- He will adjust the EEG machine settings
- The technician will then ask to close the eyes, put your hands
in a still position and relax. Try not to fall asleep during this
- You will be asked to open your eyes for a short while and close
your eyes again among the normal procedure.
- Provocation: while closing your eyes, intermittent flashes of
light will be applied, the technician will also ask you to breathe
slowly and then fast for almost three minutes continuously.
After the procedure
After the test is complete, the technician will remove the
electrodes. The patient will be instructed when to resume any
medications. The patient generally will be ready to go home
immediately following the test. No recovery time is required.
Because the patient may be at risk for a seizure (especially if
their medication has been withheld prior to the EEG), a companion
will escort the patient home. The patient will be instructed as to
when to pick up the result of his test.
