In-Home Video EEG

Why AEEG with Video?

Until recently, prolonged EEG-video monitoring has been performed in an in-patient setting. These studies are often costly, may be inconvenient and are at times uncomfortable for patients. However, improvements in computer storage, processing and remote access for video have opened the door for EEG-video to move from an in-patient setting to an ambulatory or home setting. Providing in-home EEG reduces cost, enhances p


atient satisfaction and is making AEEG with video the Gold Standard in EEG testing.

Because studies are administered in an environment most comfortable to the patient, this home setting is also where a patient has their typical stressors that trigger a seizure-like event. The convenience of in-home AEEG is ideal for patients who can’t drive, who live in rural areas, who are disabled or bed ridden, or have young children and other significant family commitments.

Ambulatory EEG-Video also allows the doctor to understand what the patient’s symptoms are during their typical day with flexibility and portability rather than the confinement to an EMU hospital bed. Another benefit to in-home AEEG’s is the ability to capture a patient’s natural sleep pattern from 1 day – 5 days. This is critical because up to 75% of seizures or abnormalities often occur at night.

A high quality AEEG should provide clear audio of the patient, video of the patient, EEG waveforms, as well as patient documentation of daily events. These data elements combined provide the doctor with a high diagnostic yield for improved patient care, diagnosis and treatment.

Quality of AEEG with Video

Leads are glued on with collodion -- just as in an EMU lab -- making the application sturdier than just gauze and paste. Our AEEG tests are logged into at least 3 times a day remotely by a technologist for quality assurance. If any wires look bad or the quality of any aspect of the study is poor, our technician will fix it upon notification.

During the patient set-up, we advise the patient/patient’s family not to disturb the electrodes that are attached to the scalp and to stay on camera as much as possible during all waking and sleeping hours. We educate the patient and patient’s family on the laptop and camera and the importance of frequently checking that the patient is centered on the screen. We also require the patient to conduct a daily “eye test” to provide a baseline for us consisting of eye closing and eye opening with NO talking, NO chewing, NO smiling, NO other movement. The daily eye test is also noted in the Patient Diary so that our scanning technologists can cross reference this baseline.

Benefit of AEEG with Video

Up to 30% of people with seizures do not have epilepsy and their AEDs are not necessary. The purpose and benefit to adding the video component to AEEG is to see the patient’s clinical characteristics and/or events and how they correlate to the EEG data. The video aspect helps physicians differentiate if a patient's movements are artifact versus cerebral and also helps locate the area in the brain where abnormalities occur to aid in proper diagnosis and seizure treatment. If a seizure is non-epileptic, the video recording can assist the physician to determine if they are psychogenic or organic events, thereby determining a different course of treatment.

You would be amazed at how helpful the video is in telling me the story. I can have a 99% confirmed diagnosis by seeing the events on video.” – Dr. Katherine Standley, Neurologist
