EEG Test in Bangalore: Everything You Need to Know

If you’re experiencing unexplained seizures, dizziness, or memory issues, a doctor might recommend an EEG (Electroencephalogram) test. This diagnostic tool helps assess brain activity and detect neurological disorders. If you’re looking for a reliable EEG test in Bangalore, understanding the process, costs, and benefits is essential.

In this guide, we will delve into everything about EEG tests, including their significance, how they work, the procedure, and what to expect before and after the test.

What is an EEG Test?

An EEG (Electroencephalogram) is a non-invasive diagnostic test used to monitor electrical activity in the brain. It is commonly used to diagnose conditions such as epilepsy, sleep disorders, and other neurological conditions.

Why is an EEG Test Performed?

Doctors may recommend an EEG test to:

• Diagnose epilepsy and other seizure disorders
• Monitor brain activity after head trauma
• Investigate sleep disorders such as insomnia and sleep apnea
• Detect brain inflammation (encephalitis) or tumors
• Assess cognitive impairments or brain dysfunction

How Does an EEG Work?

The brain’s neurons communicate through electrical signals. An EEG test records these signals using small electrodes placed on the scalp. The data collected provides insights into brain function and helps diagnose any irregularities.

Types of EEG Tests

There are different types of EEG tests depending on the condition being diagnosed:

1. Routine EEG

• Standard procedure lasting 20-40 minutes
• Used for general brain function assessment

2. Ambulatory EEG

• Records brain activity for 24-72 hours
• Allows for continuous monitoring outside the hospital

3. Sleep EEG

• Conducted during sleep
• Helps diagnose sleep disorders and nocturnal seizures

4. Video EEG Monitoring

• Combines EEG with video recording
• Useful for diagnosing epilepsy and monitoring seizure activity

Preparing for an EEG Test

Proper preparation ensures accurate results. Here’s what you should keep in mind:

Before the Test

• Wash your hair – Avoid using any hair products that may interfere with electrode placement.
• Avoid caffeine – Stimulants can alter brain activity.
• Follow medication instructions – Some medications may need to be adjusted before the test.
• Sleep well – In some cases, sleep deprivation may be required.

During the Test

• Electrodes will be attached to your scalp using a special gel.
• You’ll be asked to remain still and follow instructions such as opening and closing your eyes.
• Sometimes, flashing lights or breathing exercises are used to trigger brain activity.

After the Test

• No recovery time is needed.
• You can resume daily activities immediately.
• Results will be analyzed by a neurologist.

Benefits of EEG Testing

An EEG test is a crucial diagnostic tool with several advantages:

• Non-invasive and painless – No discomfort during the procedure.
• Accurate diagnosis – Helps detect neurological disorders effectively.
• Quick procedure – Most EEG tests take less than an hour.
• Monitors brain function over time – Essential for patients with chronic conditions.

Cost of EEG Test in Bangalore

The cost of an EEG test varies depending on factors like the type of test and the diagnostic center. In Bangalore, the price typically ranges between ₹1,500 – ₹7,000. It is advisable to consult with different diagnostic centers to find the best option within your budget.

Frequently Asked Questions (FAQs)

1. How long does an EEG test take?

A routine EEG typically takes 20-40 minutes, while long-term monitoring can last 24-72 hours.

2. Is an EEG test painful?

No, an EEG test is completely painless. It involves placing electrodes on the scalp without causing discomfort.

3. Can an EEG detect brain tumors?

EEG tests detect electrical activity but cannot identify structural abnormalities like tumors. An MRI or CT scan is needed for tumor detection.

4. What should I avoid before an EEG test?

Avoid caffeine, smoking, and using hair products. Also, follow any specific instructions given by your doctor.

5. Can I eat before an EEG test?

Yes, you can eat before the test. However, avoid caffeinated drinks as they may affect the results.

6. Do I need to stop taking medications before an EEG?

Your doctor will advise you on whether to continue or pause any medications before the test.

7. What happens if my EEG test results are abnormal?

Abnormal results may indicate epilepsy, brain injury, or other neurological disorders. Your doctor will discuss further steps based on the findings.

8. Can stress affect EEG results?

Yes, stress and anxiety can impact brain activity, potentially influencing EEG readings.

9. How do I know if I need an EEG test?

If you experience seizures, dizziness, memory loss, or unexplained neurological symptoms, your doctor may recommend an EEG.

10. Is EEG safe for children?

Yes, EEG is completely safe for children and is commonly used to diagnose epilepsy and developmental disorders.
