EEG stands for Electroencephalogram, a diagnostic method used to record electrical activity in the brain. This technology allows doctors to observe brain waves and detect disorders such as epilepsy, stroke, and others.

Benefits of EEG

EEG plays a crucial role in the medical field, especially for:

1.    Diagnosing epilepsy: EEG can show abnormal electrical activity characteristic of people with epilepsy.

2.    Monitoring other brain issues: such as brain tumors, inflammation, brain injuries, Alzheimer's disease, and stroke complications.

Preparing for an EEG Examination

Before undergoing an EEG, several preparations are needed:

1.    Provide medical history: Inform the doctor about your health conditions, allergies, and current medications.

2.    Wash hair: Ensure your hair is clean and conditioner-free so electrodes can adhere properly.

3.    Do not fast: Low blood sugar levels can affect EEG results. 

EEG Examination Procedure

1.    Electrode placement: Several electrodes will be attached to your scalp to record brain electrical activity.

2.    Examination duration: Typically lasts between 20-40 minutes.

3.    Special instructions: During the examination, you may be asked to perform activities like deep breathing or looking at flashing lights to monitor brain responses.

Side Effects of EEG

EEG is a safe procedure with minimal risk. However, electrodes attached to the scalp may cause mild irritation. For patients with epilepsy, certain stimuli during the EEG may trigger seizures.
