EEG: What You Need To Know
EEG Overview and Purpose
An EEG, or Electroencephalogram, records brain activity through a non-invasive procedure. Small metal discs, known as electrodes, are placed on the scalp. These electrodes detect electrical signals from the brain.
The purpose of an EEG is to identify problems related to electrical activity in the brain. It assists in diagnosing conditions such as:
- seizures
- epilepsy
- issues with loss of consciousness or dementia.
Additionally, EEGs are valuable in research, including clinical trials, to examine the impact of new drugs on brain activity.
In essence, an EEG measures the electricity in the brain, providing insights into brain function under various conditions.
Conducting and Preparing for the EEG Test
An Electroencephalogram (EEG) test measures electrical activity in the brain and is utilized in the diagnosis of conditions such as epilepsy or sleep disorders. The procedure is non-invasive, with no surgery involved.
Before undergoing an EEG, it is necessary to:
- Avoid caffeine and certain medications, as these substances can influence test results.
- Wash hair the night before the test, without the application of any hair products afterwards.
During the procedure, the EEG technician places small metal discs, known as electrodes, on the scalp. These electrodes are attached using a special adhesive or paste to ensure they remain in place. It is important for the individual to remain still during this process to prevent false readings. The electrodes capture the brain's electrical signals, which are later interpreted by a neurologist.
The duration of the test typically lasts about an hour, though overnight monitoring may be required for a more comprehensive analysis. The process is designed to be pain-free.
The information gathered from an EEG provides valuable insights into brain activity, contributing to the understanding and diagnosis of neurological conditions.

Interpreting EEG Results and Post-Procedure Instructions
An EEG test measures brainwave activity, capturing electrical activities of neurons in specific regions of the brain. Abnormal patterns in these measurements may indicate conditions such as epilepsy or brain injury.
The interpretation of these results is conducted by physicians who look for unusual spikes or patterns in brainwaves that could suggest a neurological disorder.
The procedure for an EEG is noninvasive and typically allows for the resumption of normal activities immediately afterward, although caution is advised if sedatives were used during the procedure.

Clinical Trials, Risks, and Conditions Diagnosed by EEG
Clinical trials involve research using human volunteers to evaluate a medical, surgical, or behavioral intervention. The knowledge gained is crucial for developing new treatments or improving existing ones.
An EEG, short for Electroencephalogram, is a diagnostic tool that measures electrical activity within the brain through the scalp. It is non-invasive and safe, used to diagnose various conditions including epilepsy, sleep disorders, encephalopathies (brain dysfunction), and more.
However, clinical trials also carry risks; unforeseen side effects may occur. These side effects can range from mild to severe or life-threatening, especially if the condition being treated is serious. Additionally, the treatment under study might not be effective for every participant, despite being beneficial for others.
Clinical trials are a pivotal part of medical research, offering the potential for new treatment options.
EEG in Epilepsy Diagnosis
Epilepsy is a neurological disorder characterized by seizures. An effective tool in diagnosing epilepsy is the electroencephalogram (EEG).
What is EEG? EEG stands for electroencephalogram, a test that measures brain activity. It utilizes small, flat metal discs called electrodes to detect electrical patterns in the brain.
In the diagnosis of epilepsy, EEGs play a crucial role. They record the brain's electrical activity, allowing for the identification of unusual patterns that may indicate epilepsy.
- EEGs can also differentiate between types of seizures, aiding healthcare providers in determining the most appropriate treatment plan.
The procedure for an EEG is designed to be neither painful nor hazardous, typically lasting about one hour and conducted by trained medical personnel.
Early diagnosis of epilepsy enables the prompt initiation of treatment.
