Electroencephalography (EEG) is a test that looks at the naturally occurring brain activity and assesses the function of the brain.
Small painless electrodes are attached to the scalp with a paste, and a specialist physiologist records the electrical activity. This is then reported by a consultant Neurophysiologist.
What do we offer?
MediServices offer a 7-day week cover for in-patients and regular out-patient clinics.
Types of EEG
Routine EEGThis test Is usually run for 20-60 minutes and provides an overview of the patient's background state. This is the most common test to be performed and can be done on NICU babies, pediatrics, adults, in-patients, out-patients, and those in Intensive care. Photic stimulation (flashing lights) and hyperventilation (deep breathing) may be used in order to elicit typical symptoms.
In-patient EEGWe provide bedside testing and same-day reporting. Our in-patients are seen within 24hrs of referral. We can also provide long-term monitoring of in-patients with regular updates to the referring consultant as the EEG is happening.
Long-term monitoring or video telemetry/ambulatory EEG
The sensors are attached to the patient with a specialist adhesive to ensure connectivity for days. This can be used on out-patients who go home with the equipment and camera.
Alternatively on in-patients, which is particularly of use in ITU or NICU where the patients can be monitored in real-time and updates to doctors provided when any change occurs. The EEG is recorded from 24-72 hours for out-patients and up to 7 days for in-patients.
Sleep studies – Sleep-deprived EEGThese are normally performed on patients after a period of sleep deprivation. This provides a more in-depth test and is done on out-patients who are able to come into sleep whilst the EEG is recording.
MSLT (Multi sleep latency testing)These tests are performed on out-patients following a sleep assessment. A sleep diary is created beforehand and assessed by our team. Once this is done the patient will attend the clinic for the entire day and have 5 opportunities to sleep. The rate of sleep onset and sleep stage is calculated using EEG, cardiac, muscle, and respiratory sensors.
SSEP (Somatosensory evoked potentials)
Somatosensory evoked potentials are used to assess the pathway from the peripheral to the central nervous system. Small electrical impulses are given to your arms and legs and recorded with sensors on your head. These tests can be performed as in-patients or out-patients.
Out-patients normally present with specific (symptoms in one or two limbs) or general nerve symptoms and are assessed in the clinic by our specialist physiologists. For inpatients on ITU SSEPs are commonly used for neuro-prognostication, alongside EEG following severe brain injuries.
Your consent for the test, video, photic stimulation and hyperventilation will be gained during the test. It is important to remember that hyperventilation and photic stimulation carry a small risk that may set off some typical symptoms but this is a very low risk and you are closely monitored for any changes.
If anything were to happen you will be looked after by the staff and cared for appropriately.
Sleep deprived patients should not drive to or from their appointments and should have a full night's sleep before operating machinery or driving again.

MediServices Healthcare continuously strives to uphold an excellent standard of service.
Led by our Medical Director, our clinical governance committee ensures that the quality of all services is continually monitored and reviewed.
MediServices Healthcare is committed to providing seamless insourcing and outsourcing solutions, our clients are at the heart of everything we do.
MediServices Healthcare Ltd has been supporting us on an ad-hoc basis since 2021 with our waiting lists. We have found them always responsive and their sonographers have fitted well within our inhouse teams. Their team are extremely helpful and always strive to improve the service they offer, by asking for feedback. Great team to work with and would definitely recommend their service.
In order to support our diagnostic backlogs, following a competitive tender MediServices Healthcare was contracted to support us for a period of 9 months. During this time they helped us to provide both EEG and EMG patients with their tests in a timely manner.
Coordinating the effective transfer of information and contacting patients for both EEG and EMG tests was a huge undertaking. However, the service that was provided was excellent, and would not have been possible without the proactive nature of the team and the exemplary team members allocated to this project. I would like to thank MediServices Healthcare, most sincerely, for their patience and the high-quality service that was provided over the period of 10 months.
SRFT have been working with MediServices for a number of years.
SRFT is one of the largest neurosciences centres in the country and has a significant and growing need for neurophysiological services including IOM and EMG. We have found MediServices to be consistently professional, flexible, and responsive to our service needs over this period and would have no reservations in recommending their services to other providers.
We have worked with MediServices for over 12 months and developed a close working partnership with both the visiting neurophysiologists and health care assistants (HCAs). Their continuing professionalism and commitment to supporting our neurophysiology service have enabled our neurophysiology service in Wolverhampton to maintain waiting times and provide patients with first-rate service.
The MediServices team has seamlessly integrated into the team, quickly adapting to our routine of working, but more importantly have been friendly and willing to help with any issues. We have utilised MediServices in a variety of ways, to reduce EMG and EEG waiting lists or to cover Consultant leave and MediServices have accommodated our needs with no fuss in negotiating the best arrangement to provide a complete service.
Patients have nothing but praise for all the MediServices personnel, complimenting them on their kindness and ability to make them, as patients, feel relaxed and at ease.
I wanted to say thank you so much for the excellent professional support you have given the department over the past 8 months (EMG/NCS). We have really enjoyed working with you. The consultants that you have provided us have been of excellent professional standards.
I would like to say Dr A has been amazing and has been an absolute pleasure to work with. We are now in the excellent and fortunately position to have appointed a substantial consultant, but I would still like to keep our working relationship open so that if we did need cover for sickness or holidays we could get in touch.
Thought I would drop you a line to say how brilliant the two members of staff were that completed the EEG on my son today. They made him feel completely at ease, were patient and answered all of our questions as well as being very kind.
