COVID-19 restrictions to remain in place at The Walton Centre

Restrictions remain in place across the NHS in relation to the COVID-19 pandemic. The safety measures in place over the 18 months therefore remain in place at The Walton Centre - and in our other clinic settings within the community – until further notice.

Due to the increased transmission risk posed by the Omicron variant, visiting has been suspended within The Walton Centre except for exceptional circumstances.

What is epilepsy?

Epileptic seizures occur when there is an episode of abnormal electrical activity within the brain. There are a number of different types of seizure, which might result in abnormalities of the senses (such as tastes or smells), involuntary body movements, a loss of or impaired consciousness, or collapse and convulsion.

A diagnosis of epilepsy is given when a person has had two or more unprovoked seizures. There are many different causes of epilepsy, for example some people may have a genetic cause for their epilepsy, while others may have a epilepsy as a consequence of a head injury.  We recognise a number of different types of epilepsy according to the types of seizure, cause and age of onset.

Epilepsy is a common condition, and three to five in 100 people will be given the diagnosis at some point in their life time. For most people given the diagnosis, the outlook for seizure control is good, as 60 to 70 per cent of people will have their seizures controlled with medication. Around 30 per cent of people do not achieve seizure control and require specialist assessment to ensure that the diagnosis is correct, the appropriate medication has been given, and to consider whether surgery might be a treatment option.

The Walton Centre Epilepsy services

The Walton Centre has a world-class reputation for our epilepsy service, having organised – in conjunction with The University of Liverpool – the largest ever randomised controlled trials of treatment. These include trials on when to start or stop treatment for epilepsy, and comparing the available drugs for initial treatment.

Our epilepsy services are huge and comprehensive, including specialist video-telemetry diagnostics, an epilepsy surgery programme - offering the full range of procedures - and specialist neuropsychological support for patients with epilepsy and those with non-epileptic attack disorder.


The Epilepsy Team

At The Walton Centre, we have a multidisciplinary team who are all involved in patient care, including clerical staff, nurses and doctors.

At an initial meeting in the department, a patient will see one of the doctors. There are seven consultant neurologists with a specialist interest in epilepsy, who run clinics at The Walton Centre.

The role of the doctor is to determine the correct diagnosis and treatment plan. The consultant may give advice to the patient's GP or continue to monitor the patient's progress through regular outpatient appointments.

The specialist nurses are also an essential part of the team, and provide extra support at the time of diagnosis, and in the long-term management of patients with a complex condition such as epilepsy.

The consultants have access to order investigations such as EEG (Electoencephalography - measures the brain's electrical activity) or brain scanning where appropriate. However, the diagnosis of epilepsy is based on the description of symptoms rather than any investigations, which may provide supplementary information in some cases.
