EEG Test in Tuticorin

An electroencephalogram, or EEG, is a diagnostic test that analyzes the electrical activity of the brain. Healthcare professionals use EEG tests to diagnose brain-related conditions. In this test, electrodes are placed on the scalp to track the brain’s electrical activity and detect potential brain-related problems.

What is an EEG?

An EEG or electroencephalogram is a test that measures the electrical activity of the brain. It is used to detect potential brain-related problems. This test uses small metal discs called electrodes, which are placed on the scalp. These electrodes track the brain’s electrical activities and send signals to the computer to record the results.

The EEG result shows the brain’s electrical impulses in wavy patterns, which help doctors examine the brain. Abnormal wave patterns may indicate a sign of seizures or potential brain disorders.

Why is an EEG done?

EEGs are widely used to detect issues in the electrical activities of the brain, related to certain brain disorders. Generally, EEGs are done to detect various conditions, such as:

• Head injury
• Brain tumor
• Encephalitis
• Encephalopathy
• Seizure disorder
• Sleep disorder
• Stroke
• Dementia

This test is also done in someone who is in a coma to determine their level of brain functioning.

Are there any risks associated with an EEG?

EEG is painless and usually does not cause any side effects. However, some people may feel dizzy during the test. On the other hand, for people with certain forms of epilepsy, deep or light stimulation during the test process may induce an epileptic seizure. Although this only occurs sometimes, the technician will help you out during this situation.

What could interfere with the EEG reading?

Various factors may interfere with the EEG reading, such as:

• Heartbeat
• Pulse
• Breathing
• Mouth movements
• Muscle movements
• Sweating

Other factors that could affect the EEG readings include:

• Low blood sugar level
• Certain medications (such as sedatives)
• Oily hair or hair spray
• Caffeine

How to prepare for EEG?

There are a few factors that you should follow before going for the test:

• You should consult your doctor if you take any medications before the test. Your doctor may suggest whether you must take or stop them.
• Wash your hair the night before the test, and do not use any oil, gel or spray on the hair.
• Although you can eat food, avoid drinking caffeine beverages 8 hours before the test.
• Your healthcare provider may ask you to sleep less than usual, because you may be required to sleep during the test. The technician may give you sedatives to help you relax and sleep during the test.

What happens during the test?

An EEG test measures the electrical activity of the brain by attaching electrodes to the scalp. These electrodes help transfer information from the brain to the computer which monitors or records the data.

The whole process takes 30 to 60 minutes and involves the following steps:

• You have to sit or lie down on a recliner chair or bed.
• The technician will measure your head and mark areas to place the electrodes. The technician may apply a special cream on those spots to help electrodes get high-quality readings.
• They will apply a sticky gel adhesive on the electrodes to attach them to the scalp.
• During the test, the electrodes transfer electrical impulses from the brain to the computer. The machine converts the information into visual wave patterns on the screen.
• The technician will guide you throughout the test procedure. They may ask you to stay still, close your eyes, breathe deeply, or look at a picture or flashing light.

However, you may feel slight discomfort during the test because little electricity passes through the electrodes to the skin.

What happens after the test?

Once the test is complete, the technician will remove the electrodes from the scalp. However, if you are given sedatives during the test, the medicine may stay in the system for slightly longer. This is why it is important to bring someone with you, who can take you home.

What do the test results mean?

A neurologist will interpret the readings from the EEG and then send it to the doctor. The doctor will interpret the test result.

Normal result

The EEG test shows the brain’s electrical activity as wave patterns. Distinctive levels of consciousness, including walking and sleeping, have a particular range of wave frequencies per second, considered normal. For instance, the wave frequencies move quicker when you are awake than sleep.

Abnormal result

Abnormal EEG results may occur due to:

• Head injury
• Epilepsy or other type of seizure disorder
• Encephalitis
• Sleep disorder
• Tumor
• Abnormal bleeding or hemmorhage
• Migraine
• Dead tissue due to blockage of blood flow
• Excessive alcohol or drug use

However, it is a general interpretation of an abnormal EEG result. You must consult your doctor for a better understanding of your test result.
