Neurofrailty: A Study of Late-onset Epilepsy and Its Associations

There is not much known about why some people develop seizures in adulthood, but some researchers think that it might be a warning from the body to highlight something may be wrong with the brain. A small number of people with first seizure in adulthood go on to experience problems like stroke or dementia later in life. However, stroke and dementia are common diseases, so it is not know whether there is a real association between these conditions. When people develop their first seizure in adult life, this is sometimes called Late-Onset Epilepsy. The NeuroFrailty study, will observe 'brain health' over the years following the onset of a seizure, to provide more information about people with these kinds of seizures.

The NeuroFrailty study involves observing people from the time of diagnosis of first seizure. It will look at investigations such as blood tests, blood pressure, brain scans, alongside other diagnoses to compare difference to people without seizures. The study will also review some participants to look in greater depth at lifestyle including exercise, driving, family planning, and memory assessments. The study will review how changes occur over a number of years: for example whether there are changes in memory, new diagnoses, medication changes and how lifestyle has changed. Because there is so little research in this area, it is very difficult to predict what might happen. For example, some people can experience worse memory because of medication side effects; on the other hand, good seizure control following a diagnosis can sometimes lead to improved memory. Over years, it may become clear that some diseases are more likely in people with late-onset epilepsy than in people without such a diagnosis. Purpose and Background Some researchers think there may be a connection between epilepsy which starts in adulthood, and increased risk of stroke or dementia in the future. However, there is very little research or evidence in this area. This study is an observational study, which means that the management of participants' seizure disorder will not be affected if they choose to take part in this study. The purpose of this study is to watch participants over the course of several years, to find out more about seizures which start in adulthood. Participants can choose the level of involvement that is right for them. 1. LOW involvement. A researcher will check hospital and General Practice (GP records) once or twice per year, for the limited and specific purpose of checking: medications, any new diagnoses, investigations associated with stroke risk (such as cholesterol, blood pressure, heart trace) and any brain scans that have been performed. 2. HIGH involvement. This involves being contacted by telephone once per year for 15-30 minutes to ask questions assessing memory and enquiring about lifestyle, such as exercise, smoking and alcohol use. 3. VERY HIGH involvement. These participants will be contacted for a longer telephone conversation 30-45 minutes once per year about their experience of how epilepsy has affected home life, work and medications. Glossary Seizure disorder = any disorder which involved having experienced at least one seizure. First seizure and epilepsy both can be classed as a form of seizure disorder. Neurofrailty = A condition whereby a person is at risk of stroke or dementia.
