Can a 24-hour EEG be performed at home?

Generally, a 24-hour EEG (electroencephalogram) can be performed at home. The detailed explanation is as follows:

This examination uses a portable recording device. Electrodes are attached to the scalp and connected to a lightweight recorder, allowing patients to complete the monitoring in their daily lives without affecting basic activities. This method can more accurately capture brain electrical activity under natural conditions, especially suitable for detecting abnormal discharges during nighttime or daily activities. Before the examination, medical staff will install the electrodes and adjust the equipment. Patients need to carry the recorder home and avoid strenuous exercise, water contact, and electromagnetic interference during the monitoring period. They should also keep a log of their activities, such as seizure times and sleep periods. After 24 hours, patients return to the hospital to have the equipment removed, and technicians will analyze the recorded data.

Home-based 24-hour ambulatory EEG is a commonly used clinical monitoring method. Its advantages lie in extending recording time and improving the detection rate of abnormal brain activity, while not interfering with the patient's normal life. During the examination, patients must strictly follow the instructions of medical staff, properly protect the equipment and electrodes, and ensure data integrity, providing reliable evidence for disease diagnosis.
