How to prepare for a ambulatory EEG

Wash your hair and use no conditioner or styling product, plan for several days without washing it again, arrange loose clothing that opens at the front, and be ready to keep a written diary of any episodes. Take your usual medications unless told otherwise.

Quick answer

Wash your hair and use no conditioner or styling product, plan for several days without washing it again, arrange loose clothing that opens at the front, and be ready to keep a written diary of any episodes. Take your usual medications unless told otherwise.

Hair and skin

Wash your hair the morning of the fitting and use nothing afterwards: no conditioner, oil, gel, spray or dry shampoo. All of them stop electrodes making good contact, and on an ambulatory study poor contact does not just delay the start, it degrades days of recording. Braids, extensions and hairpieces should be mentioned when you book, because they affect where electrodes can be placed and how long fitting takes.

Clothing and daily life for the recording days

Bring a top that opens at the front, since you will not be able to pull clothing over your head once the equipment is fitted, and pack the same for the following days. Keep everything dry: no showering, swimming or heavy sweating. Most people manage with a careful wash at the sink. Sleep normally, because sleep is often when the most useful activity appears, and carry on with ordinary activity rather than staying home.

The diary is the part people underdo

Note the time of anything that felt like an episode, what you were doing, and what it felt like. Pressing the event button without recording the context loses half the value, because correlating a logged event with the trace is the single most useful result this study can produce. Also note sleep times and any missed medication. Both visits are at the same office and neither involves sedation, so you can drive yourself to each.

Frequently asked

Questions about how to prepare for a ambulatory EEG

How do I prepare for an ambulatory EEG?
Wash your hair with no product afterwards, bring front-opening clothing, plan for several days without washing your hair, and be ready to keep a written episode diary. Take medications as usual unless specifically told otherwise. Mention braids, extensions or a hairpiece when you book, since they affect where electrodes can go and how long fitting takes.
Can I wash my hair during the recording?
No. Keeping the equipment dry is the main restriction for the whole recording period, so showering, swimming and heavy sweating are out. Most people manage with a careful wash at the sink. Factor that into when you schedule it, because several days without washing your hair is easier some weeks than others.
What should I wear?
Tops that open at the front, for the fitting and for every day of the recording, because you will not be able to pull clothing over your head with the equipment in place. Comfortable and loose is easier than fitted. Pack the same for every day of the recording, not just the fitting appointment.
What do I write in the diary?
The time of anything that felt like an episode, what you were doing at the time and what it felt like, plus sleep times and any missed medication. Context matters as much as the timestamp. Pressing the event button without recording the context loses half the value, because matching a logged event to the trace is the most useful result this study produces.
Should I change my routine?
No, and you should not. The study is trying to capture ordinary life, so normal activity and normal sleep make the recording more useful. Deliberately resting at home reduces the chance of capturing what you came in for. Deliberately resting at home reduces the chance of capturing what you came in for, so carry on as normally as the equipment allows.
