An EEG full form is electroencephalogram, which is a methodology that provides small metal plates (called electrodes) connected to your scalp to record the electrical signals of your brain. Electrical impulses are used by your brain cells to communicate with one another.
Even when you're sleeping, they're at work. Wavy lines will appear on an EEG recording as a result of this brain activity. It's a snapshot of your brain's electrical activity at a specific point in time. EEG happens to be one of the most frequently used and conducted test to diagnose epilepsy. Different types of brain diseases can also be diagnosed through an EEG test.
EEGs are used to diagnose these illnesses.
- Brain tumours
- Damage to the brain as a result of a head injury
- Brain malfunction due to a variety of factors (encephalopathy)
- Cerebral inflammation (encephalitis)
- Epilepsy and other seizure disorders
- Sleep disturbances
An EEG can also be used to identify if a person in a coma has deceased or to establish the appropriate amount of anaesthetic for a coma patient.
EEG Test Risks
EEGs are completely safe. If you're having a medical problem, discuss it with your doctor before the test. There's a chance that the EEG's bright lights and taking deep breaths will trigger a seizure if you have a psychotic disorder. This is unusual. If this occurs, medical staff will be on standby to treat you right away.
In some situations, a doctor will induce a migraine during the exam to obtain a reading. Medical personnel will be present to keep an eye on the issue.An EEG test cost can go up to INR 3500 depending on the labs you choose.
EEG Test Near Me: Test Preparation
- You should do the following to qualify for EEG:
- Don't consume any caffeine-containing foods or beverages for at least 8 hours in advance.
- If you're anticipated to sleep throughout the EEG, your physician may give you advice about how much to sleep.
- On the evening before and the day of the surgery, eat normally. Low blood sugar levels can lead to unexpected outcomes.
- Tell your doctor about any medications or supplements you're taking, both prescription and over-the-counter.
- The evening before the test, wash your hair. After that, don't use any start leaving conditioners or styling products. If you're wearing glue-on extensions, you should take them off.
Medication and food
- Caffeine-containing beverages should be avoided on the day before the test since it might alter the results.
- Take your regular medications unless otherwise directed.
- Additional precautions
- Do not use moisturizers, hair creams, sprays, or style gels on your hair the night prior or the day of the test. Beauty products can make it more difficult for the electrodes' sticky patches to stick to your scalp.
- If you're scheduled to nap during your EEG test, your doctor may advise you to sleep less or not at all the night before.
What You May Anticipate?
During the examination.
During an EEG, you should experience little to no discomfort. There are no sensations sent by the electrodes. They simply take notes on your brain waves.
When in an EEG, you can expect the following to happen:
- A technician takes your head measurement and traces your head with a specific pencil to designate where the electrodes should be attached. To improve the product quality of the recording, scrape those regions on your scalp with a grainy cream.
- A technician uses special glue to adhere discs (electrodes) to your scalp. An elastic hat with electrodes is sometimes used instead. Wires link the electrodes to an apparatus that enhances the brain waves and stores them on personal computers.
- An EEG might take up to 60 minutes after the electrodes are in place. Certain circumstances necessitate sleeping throughout the examination. The exam can be extended in this scenario.
- During the exam, you rest in a comfortable spot with your eyes closed. The technician may ask you to raise and shut your eyes, conduct just a few quick arithmetics, read a phrase, look at a picture, take a few deep breaths, or stare at a flashing light at various intervals.
- During the EEG, video is typically recorded. A video camera records your body movements, while the EEG captures your brain signals. Your doctor can use this combined recording to accurately diagnose your condition.
After an EEG
Following the completion of the EEG, the following will occur:
- The technician will remove the electrodes and remove the glue that was used to keep them in place. To remove any remaining stickiness, apply a small amount of nail paint remover at home.
- You can head home unless you're having a seizure or your doctor advises you shouldn't. If the EEG was performed overnight, however, it is preferable to have others drive you.
- Medications that you had stopped particularly for the test can typically be resumed.
- Your brain wave patterns will be examined by a neurologist, a specialist who specializes in the brain.
The EEG data will be transmitted to your physician, who will go through them with you once they have been analysed. A succession of wavy lines will appear on the EEG. Based on if you were awake or asleep throughout the test, the lines will appear differently, but each condition has a typical pattern radiology labs of brain activity. It could be an indication of seizures or another brain condition if the typical sequence of neural activity has been disrupted. You don't have epilepsy just because your EEG is abnormal. The testing just captures what is going on in your head at the time.
Other tests will be performed by your doctor to help diagnose.
EEG test price ranges between INR 1000 to INR 3500.
Doctors have been trained to interpret EEG recordings to assess the recording and post the findings to the physician who requested the EEG. Your doctor may schedule an appointment with you to discuss the test results. If at all possible, bring a friend or family member to the meeting to assist you in remembering the facts.
