EEG Test in Bhandup (Mumbai)

An Electroencephalogram (EEG) is a diagnostic test that measures and records the electrical activity of the brain. It is a non-invasive and painless procedure that helps healthcare professionals assess brain function and diagnose various neurological conditions. Here are the details of the EEG test:

1.Purpose:

    • Diagnosis: EEG is commonly used to diagnose conditions such as epilepsy, seizures, and other neurological disorders.

    • Monitoring: It is employed to monitor brain activity during sleep, surgery, or to assess brain function in critical care settings.

    • Research: EEG is used in research to study brain activity patterns and cognitive processes.

2. Preparation:

    • Hair Care: Patients may be asked to wash their hair before the test to remove oils and products, making it easier for the electrodes to adhere.

    • Medication: Some medications may need to be adjusted or temporarily discontinued before the test. Always follow the healthcare provider's instructions.

3. Electrode Placement:

     • Small, flat metal electrodes are attached to the scalp using a conductive gel or paste. The number and placement of electrodes depend on the type of EEG being performed.

     • Electrodes are strategically positioned to record electrical signals from different regions of the brain.

4. Recording:

     • The electrodes pick up electrical signals generated by the brain's neurons. These signals are then amplified and recorded as wave patterns on a computer or paper.

     • During the test, the patient may be asked to close their eyes, open their eyes, breathe deeply, or perform other tasks to provoke specific brain responses.

5. Duration:

     • The duration of the EEG varies. A routine EEG typically lasts around 20 to 60 minutes. In some cases, longer-term monitoring (ambulatory EEG) may be done over 24 hours or more.

6. Types of EEG:

     • Routine EEG: Records brain activity during rest with eyes closed and open. • Sleep-Deprived EEG: Conducted after a night of reduced sleep to provoke abnormalities.

     • Ambulatory EEG: Records brain activity over an extended period while the patient goes about daily activities.

     • Video EEG Monitoring: Simultaneously records video and EEG to capture events like seizures.

7. Interpretation:

     • EEG recordings are interpreted by neurologists or trained specialists.

     • Abnormal patterns, such as spikes, sharp waves, or irregular rhythms, may indicate various neurological conditions.

     • Interpretation considers the patient's age, clinical history, and specific circumstances surrounding the test.

8. Risks:

    • EEG is generally considered safe with minimal risks.

    • The procedure does not involve exposure to radiation.

    • There is a slight risk of skin irritation from the electrodes' adhesive.

9. Follow-Up:

    • The results of the EEG are discussed with the patient by a healthcare provider.

    • Further diagnostic tests or treatment may be recommended based on the findings.

EEG is a valuable tool for diagnosing and managing neurological disorders. If your healthcare provider recommends an EEG, it's essential to follow any preparation instructions and communicate any concerns or relevant medical history before the test.
