An electroencephalogram (EEG) is a non-invasive test that measures and records the electrical activity of the brain. It is commonly used to diagnose and monitor various neurological conditions, including epilepsy, brain tumors, and sleep disorders. To detect and record electrical signals created by the brain during an EEG, electrodes are placed on the scalp.
In preparation for an EEG, the following steps are typically taken:
Before the procedure, patients may be asked to wash their hair to remove oils or products that might interfere with electrode-skin contact.
Prior to the EEG, patients should inform their healthcare provider about any medications they are taking, as some medications may need to be adjusted or temporarily stopped.
In some cases, patients may be asked to deprive themselves of sleep for a specified period of time before the EEG in order to induce drowsiness and increase the likelihood of recording abnormal brain activity.
EEGs typically involve the following steps:
Using a special adhesive or paste, electrodes are attached to the scalp to detect and record electrical signals generated by the brain.
The EEG machine records the electrical activity of the brain as it produces alpha, beta, delta, and theta waves.
Certain conditions, such as epilepsy, can be diagnosed with specific stimuli such as flashing lights or auditory cues.
Healthcare providers monitor EEG tracings in real-time to ensure accurate recordings and identify abnormalities.
After an EEG, patients are usually able to resume their normal activities immediately.
An EEG is a safe and noninvasive procedure without any risks or complications.
Following an EEG, patients may receive the following instructions:
A healthcare provider may recommend further evaluation or treatment based on the EEG results and the patient's medical history.
Monitoring symptoms: Patients should monitor for symptoms that may indicate a neurological problem, such as seizures, changes in consciousness, or unusual sensations, and report them to a healthcare provider if necessary.
In order to diagnose various neurological conditions and assess the electrical activity of the brain, electroencephalograms (EEGs) are valuable diagnostic tools. Healthcare providers can use it to diagnose and manage neurological disorders since it is a safe and non-invasive procedure. Consult with a healthcare provider if you are experiencing any symptoms or concerns about your brain health.
