What to expect during a ambulatory EEG

Expect a longer first appointment to fit electrodes and a recorder, several days of ordinary life while it records, and a shorter second appointment to remove everything. You keep a diary of any events and must keep the equipment dry.

Quick answer

Expect a longer first appointment to fit electrodes and a recorder, several days of ordinary life while it records, and a shorter second appointment to remove everything. You keep a diary of any events and must keep the equipment dry.

The fitting appointment

This is the longer of the two visits. Your head is measured and electrode positions marked, the scalp is prepared, and each electrode is attached with paste or glue. They are then usually secured under a wrap or netting so they stay in place for days rather than hours, which is why the fitting takes longer than for a routine EEG. The recorder itself is small and worn in a pouch or on a strap. You are shown how to use the event button and given the diary, and it is worth asking any questions then rather than later.

The days in between

Go about normal life, because that is precisely what the study is trying to capture. Work, walk, cook and sleep as usual. Keep everything dry: no showering, swimming or heavy sweating, and most people manage with a careful wash at the sink. Wear tops that open at the front. Sleep on your usual schedule, since sleep is often when the most useful activity appears. Some people find the wrap uncomfortable at night for the first evening and then stop noticing it.

The diary, and the removal visit

Whenever something happens that feels like an event, press the button and write down the time, what you were doing and what it felt like. Also note sleep and wake times and any missed medication. The diary is what allows a logged event to be matched against the trace, and that correlation is the single most valuable result the study can produce, so pressing the button without noting context loses much of the point. Removal is quick; the data is downloaded and the study interpreted by the ordering neurologist.

Frequently asked

Questions about what to expect during a ambulatory EEG

What should I expect during an ambulatory EEG?
A longer first appointment to fit electrodes and a recorder, several days of ordinary life while it records, and a shorter second visit to remove everything and download the data. Throughout you keep an event diary and keep the equipment dry.
Can I go to work with it on?
Usually yes, and normal activity makes the study more useful rather than less. The equipment is visible, so some people prefer a hat or a scarf. If your work involves heavy sweating, water, or dusty environments, mention it when booking so the timing can be planned around it.
How do I sleep with it?
On your usual schedule, which matters because sleep is frequently when the most informative activity appears. The wrap can feel odd for the first evening and most people stop noticing it. Avoid heavy sweating overnight, so a cooler room helps more than extra bedding.
What if an electrode comes loose?
Call the office rather than trying to reattach it yourself, since incorrect placement produces misleading data. Note the time it happened in your diary. Losing one electrode does not usually invalidate the study, but the recording team need to know so they can account for it.
What exactly should I write in the diary?
The time of anything that felt like an event, what you were doing, and what it felt like, plus your sleep and wake times and any missed medication. Context matters as much as the timestamp, because matching a described event to the trace is the study's most valuable output.
