EEG Test in Bangalore – Everything You Need to Know

Electroencephalography (EEG) is a non-invasive diagnostic procedure that records electrical activity in the brain. It is widely used to diagnose neurological disorders such as epilepsy, sleep disorders, brain injuries, and more. If you are looking for an EEG test in Bangalore, this guide will provide you with all the essential details, including the procedure, costs, benefits, and the best diagnostic centers in the city.

What is an EEG Test?

An EEG test is a medical procedure that measures electrical impulses in the brain using small, flat metal discs (electrodes) attached to the scalp. These electrical impulses indicate brain activity and help neurologists detect abnormalities.

Why is an EEG Test Done?

Doctors recommend an EEG test for various medical conditions, including:

• Epilepsy and seizure disorders

• Sleep disorders such as insomnia or sleep apnea

• Brain injuries and trauma

• Stroke assessment

• Brain tumors

• Dementia and memory disorders

• Neurological infections

• Unexplained fainting or dizziness

Types of EEG Tests

1. Routine EEG

This is the most common type of EEG, typically lasting 20-30 minutes. It records brain activity while the patient is awake and relaxed.

2. Sleep EEG

A sleep EEG is conducted while the patient is asleep, helping to diagnose sleep disorders and epilepsy-related conditions.

3. Ambulatory EEG

This test involves wearing a portable EEG device for 24-72 hours to monitor brain activity during daily activities and sleep.

4. Video EEG

A video EEG records brain activity along with video footage to observe physical responses, making it useful for diagnosing seizures.

How to Prepare for an EEG Test

Proper preparation ensures accurate results. Here are some key steps:

• Wash your hair: Avoid using conditioners or hair gels before the test, as they can interfere with electrode placement.

• Avoid caffeine: Stimulants like coffee, tea, and energy drinks should be avoided at least 12 hours before the test.

• Follow medication instructions: Inform your doctor about any medications you are taking. Some medicines may need to be paused before the test.

• Get enough sleep: If a sleep EEG is required, you may be asked to stay awake for a specific period before the test.

• Eat normally: Fasting is not required, but it is best to have a light meal before the procedure.

EEG Test Procedure

The EEG procedure is simple and painless. Here’s what to expect:

1. Preparation: The technician cleans your scalp and places electrodes using a special adhesive.

2. Recording Brain Activity: You may be asked to perform simple tasks such as closing your eyes, breathing deeply, or looking at flashing lights.

3. Monitoring Period: The test typically lasts 20-60 minutes, but some extended versions can take longer.

4. Completion: The electrodes are removed, and you can resume normal activities.

How Long Does an EEG Test Take?

A routine EEG test usually takes around 30 to 60 minutes, while an ambulatory EEG can last up to 72 hours.

Benefits of an EEG Test

• Accurate Diagnosis: Helps in the early detection of neurological conditions.

• Non-Invasive: No pain or discomfort during the procedure.

• Quick & Safe: No exposure to radiation or harmful substances.

• Affordable: Compared to other brain imaging tests like MRI, EEG is cost-effective.

Cost of EEG Test in Bangalore

The cost of an EEG test in Bangalore varies based on the type of test and the diagnostic center. On average, the price ranges between ₹1,500 to ₹7,000. Factors affecting the cost include:

• Type of EEG test (Routine, Sleep, Ambulatory, or Video EEG)

• Hospital or diagnostic center reputation

• Additional neurological consultation

Best Diagnostic Centers for EEG Test in Bangalore

Several reputed hospitals and diagnostic centers offer high-quality EEG tests in Bangalore. Some of the top options include:

• Manipal Hospital

• Apollo Hospitals

• Fortis Hospital

• Ecotown Diagnostics

• Narayana Health

• Columbia Asia Hospital

After the EEG Test – Understanding Your Results

The EEG test results are analyzed by a neurologist. Based on the wave patterns recorded, the doctor will determine whether there are abnormalities that require further medical intervention.

Normal vs. Abnormal EEG Results

• Normal EEG: Consistent brain wave patterns indicate a healthy brain function.

• Abnormal EEG: Irregular waveforms may suggest epilepsy, brain injury, sleep disorders, or other neurological conditions.

Are There Any Risks Associated with EEG Tests?

EEG tests are completely safe and non-invasive. However, in rare cases, patients with epilepsy may experience seizures due to exposure to flashing lights during the test.

Conclusion

If you need an EEG test in Bangalore, ensure you choose a reputed diagnostic center for accurate results. This painless and effective procedure plays a crucial role in diagnosing various brain-related conditions, enabling timely treatment and better health outcomes.

FAQs About EEG Tests

1. How does an EEG test work?

An EEG test records electrical activity in the brain using electrodes placed on the scalp. These signals help doctors analyze brain function and detect abnormalities.

2. Can an EEG test detect anxiety or depression?

EEG primarily diagnoses neurological conditions. While it can show changes in brain activity related to mood disorders, it is not a definitive test for anxiety or depression.

3. Is an EEG test painful?

No, an EEG test is completely painless. The electrodes only record brain activity and do not emit any electrical impulses.

4. Can I eat before an EEG test?

Yes, you can eat before the test, but it’s advisable to avoid caffeine and other stimulants.

5. Will I need to shave my head for an EEG?

No, you don’t need to shave your head. The electrodes are placed on the scalp without any need for hair removal.

6. Can I drive after an EEG test?

Yes, you can resume normal activities, including driving, unless the doctor advises otherwise.

7. How often should an EEG be done?

The frequency of EEG tests depends on the medical condition being monitored. Your doctor will recommend how often you need to undergo the test.

8. Does an EEG show past seizures?

EEG detects abnormal brain activity at the time of recording but may not always show past seizure activity.

9. Can stress affect EEG results?

Yes, stress can influence brain wave patterns, but neurologists can differentiate stress-induced variations from neurological disorders.

10. Is fasting required before an EEG test?

No, fasting is not required, but it’s best to avoid caffeine and follow any specific instructions given by your doctor.
