About EEG Services

EEG (Electroencephalogram) Services at Nano Hospitals are specialized diagnostic tests used to measure and record the electrical activity of the brain. This non-invasive procedure helps doctors evaluate neurological conditions by identifying abnormal brain wave patterns associated with seizures, epilepsy, sleep disorders, brain infections, and other neurological concerns.

Overview

An EEG is a diagnostic test that records the brain’s electrical signals using small electrodes placed on the scalp. These signals are displayed as wave patterns that help neurologists detect abnormalities in brain function.

At Nano Hospitals, EEG services are conducted using advanced digital EEG systems that provide high-quality recordings for precise neurological assessment.

Workflow

Step 1: Doctor’s Evaluation
A neurologist recommends an EEG if a patient experiences seizures, fainting episodes, unexplained confusion, memory issues, or sleep disturbances.

Step 2: Preparation
The patient’s scalp is cleaned, and multiple small electrodes are placed on specific areas of the head using a conductive gel or paste.

Step 3: Brain Wave Recording
The EEG machine records brain activity while the patient rests quietly. In some cases, stimuli like flashing lights or deep breathing may be used.

Step 4: Monitoring Period
The test usually lasts 20–60 minutes, though longer monitoring may be required for certain conditions.

Step 5: Interpretation and Reporting
A neurologist analyses the recorded wave patterns and prepares a detailed report to guide diagnosis and treatment.

Benefits & Value

Risks & Challenges

• Mild scalp irritation from electrode placement
• Rare chance of triggering a seizure during stimulation tests
• Movement or muscle activity may affect recording quality
• Need for patient cooperation for accurate results

Frequently Asked Questions

Is EEG painful?
No, EEG is completely painless and non-invasive.

How long does an EEG test take?
Typically 20–60 minutes; longer studies may be required in some cases.

Do I need to fast before an EEG?
Usually no, unless specifically advised by the doctor.

Can EEG detect epilepsy?
Yes, EEG is one of the primary tests used to diagnose epilepsy.

Are there any side effects?
Side effects are rare; the test is generally very safe.
