An ambulatory electroencephalogram (EEG) is a prolonged test that records brain activity over an extended period, typically 24 hours or longer, while the individual continues with their usual daily activities at their residence. The goal is to capture brainwave patterns that might not be evident during a standard, shorter in-clinic EEG. For instance, a person experiencing infrequent seizures may only exhibit abnormal brain activity during one of these episodes, which might not occur during a routine EEG appointment.
This type of monitoring is particularly useful for diagnosing and managing seizure disorders, sleep disorders, and other neurological conditions. It provides a more comprehensive picture of brain function compared to a standard EEG because it captures activity over a longer duration and during normal, everyday routines. The data collected can help physicians accurately diagnose the condition, adjust medication, and develop a more effective treatment plan.
