EEG Test in Bangalore – Everything You Need to Know
An EEG (Electroencephalogram) test is an essential diagnostic tool used to monitor brain activity and detect neurological disorders. If you are experiencing symptoms like seizures, frequent headaches, or unexplained dizziness, an EEG test may help your doctor diagnose underlying conditions.
If you're looking for an EEG test in Bangalore, this guide covers everything you need to know, including the procedure, benefits, cost, and the best places to get tested.
What is an EEG Test?
An EEG test is a non-invasive procedure that records electrical activity in the brain. It is widely used for diagnosing conditions such as:
Epilepsy
Sleep disorders
Brain tumors
Stroke-related complications
Memory issues and dementia
Head injuries
By analyzing brainwave patterns, neurologists can identify abnormalities and suggest appropriate treatment plans.
How Does an EEG Test Work?
An EEG test involves placing small electrodes on the scalp, which detect electrical signals generated by brain activity. These signals are recorded and analyzed to identify irregularities. The test is painless and typically lasts between 30 minutes to an hour.
Types of EEG Tests
There are different types of EEG tests based on specific diagnostic needs:
1. Routine EEG
This standard EEG test records brain activity for a short period, usually 20-40 minutes.
2. Ambulatory EEG
This test records brain activity over an extended period (24 to 72 hours) while you continue your daily routine.
3. Sleep EEG
Conducted while the patient sleeps, this test helps diagnose sleep disorders like sleep apnea and narcolepsy.
4. Video EEG Monitoring
Used for patients with epilepsy, this test combines EEG recordings with video monitoring to analyze seizure activity.
Why Do You Need an EEG Test?
Your doctor may recommend an EEG test if you experience any of the following symptoms:
Frequent or unexplained seizures
Chronic headaches or migraines
Memory loss or confusion
Sudden unconsciousness
Unusual sleep patterns
By identifying abnormal electrical activity, an EEG test can help diagnose various neurological disorders and guide treatment plans.
Preparing for an EEG Test
To ensure accurate results, follow these preparation guidelines before undergoing an EEG test:
Wash your hair: Avoid using oils, sprays, or conditioners as they can interfere with electrode placement.
Avoid caffeine: Refrain from consuming coffee, tea, or energy drinks at least 12 hours before the test.
Sleep well: In some cases, sleep deprivation may be required to enhance the test's accuracy.
Discuss medications: Inform your doctor about any medications you are taking as some drugs can affect test results.
What to Expect During an EEG Test?
Step 1: Electrode Placement
Small, flat electrodes are attached to your scalp using a special adhesive. These electrodes are connected to an EEG machine that records brain activity.
Step 2: Recording Brain Waves
You may be asked to close your eyes, breathe deeply, or look at flashing lights to stimulate different brain responses.
Step 3: Test Completion
The procedure is painless, and once the test is done, the electrodes are removed. You can resume normal activities immediately unless instructed otherwise by your doctor.
Benefits of an EEG Test
Non-invasive and painless
Quick and efficient brain activity assessment
Helps diagnose serious neurological conditions early
No side effects
Can be used for both adults and children

Best Places to Get an EEG Test in Bangalore
Several reputed hospitals and diagnostic centers in Bangalore offer EEG testing. It is essential to choose a well-equipped facility with experienced neurologists for accurate diagnosis and reliable results.
After the EEG Test – Understanding Your Results
Once the EEG test is complete, a neurologist will analyze the results and provide a report. The findings may indicate:
Normal brain activity – No abnormalities detected.
Abnormal patterns – Irregular waves may suggest epilepsy, sleep disorders, or other neurological conditions.
If any issues are found, your doctor will recommend further tests or treatments based on the diagnosis.
10 Frequently Asked Questions (FAQs) About EEG Tests
1. Is an EEG test painful?
No, an EEG test is a non-invasive and painless procedure. You might feel slight discomfort when electrodes are attached, but there is no pain involved.
2. How long does an EEG test take?
A routine EEG test usually takes 30 to 60 minutes, while extended tests like ambulatory EEG can last up to 72 hours.
3. Are there any risks or side effects?
No, EEG tests are safe and do not have any side effects. However, patients with epilepsy may experience a seizure if exposed to flashing lights during the test.
4. Can I eat before an EEG test?
Yes, you can eat before the test, but it is advisable to avoid caffeine and energy drinks as they may affect brain activity.
5. Do I need to shave my head for an EEG test?
No, but it is important to wash your hair and avoid using hair products to ensure proper electrode attachment.
6. Can children undergo an EEG test?
Yes, EEG tests are safe for children and are often recommended for diagnosing epilepsy, developmental disorders, and sleep issues.
7. Will I be sedated for the test?
No, EEG tests do not require sedation. However, in some cases, a doctor may prescribe mild sedation for children or anxious patients.
8. How soon will I get my EEG test results?
Results are usually available within 24 to 48 hours, depending on the diagnostic center and the complexity of the test.
9. Can an EEG test detect mental disorders?
While EEG tests primarily diagnose neurological conditions, they can sometimes help in studying brainwave patterns related to anxiety, depression, and other mental health disorders.
10. What happens if my EEG results are abnormal?
If your EEG results indicate abnormalities, your doctor may recommend additional tests, medications, or treatment plans based on the findings.
