EEG

An EEG, or electroencephalogram, is a test used to evaluate the electrical activity in the brain. Brain cells communicate with each other through electrical impulses, and an EEG can be used to help detect potential problems associated with this activity. How Does an EEG Work? The EEG test involves attaching small electrodes to the scalp using a special paste or cap. These electrodes detect the electrical activity in the brain and transmit the signals to a computer, which records the results. Why is an EEG Used? An EEG may be used to: - Diagnose and monitor epilepsy: EEGs can help diagnose and monitor seizure disorders, such as epilepsy. - Investigate other conditions: EEGs can also be used to investigate other conditions, such as sleep disorders, encephalopathy, or brain injury. What to Expect During an EEG During an EEG, you will be asked to sit or lie down and relax. The test is typically painless and non-invasive. You may be asked to perform certain tasks, such as breathing deeply or looking at a flashing light, to stimulate brain activity. Benefits of EEG - Non-invasive and painless: EEGs are a safe and non-invasive way to evaluate brain activity. - Accurate diagnosis: EEGs can provide valuable information to help diagnose and monitor a range of neurological conditions. Preparing for an EEG - Wash your hair: Wash your hair with shampoo and conditioner before the test. - Avoid hair products: Avoid using hair products, such as gel or spray, on the day of the test. - Follow instructions: Follow any instructions provided by your healthcare provider or the EEG technician. Interpreting EEG Results A healthcare professional will interpret the results of your EEG and discuss them with you. Abnormal results may indicate a range of conditions, including epilepsy or other neurological disorders. Frequently Asked Questions - Is an EEG safe?: Yes, an EEG is a safe and non-invasive test. - How long does an EEG take?: The length of an EEG test can vary, but it typically takes around 30-60 minutes. - Will I feel any pain during the test?: No, an EEG is a painless test.
