Summary

Epilepsy is a disorder of the brain in which people have repeated seizures. Autoimmune encephalitis (AE) is a rare cause of epilepsy. It is an inflammatory disease of the brain. This means that the body's own immune system attacks healthy brain tissue, just like it would if it were infected by a virus or a bacteria, by producing an army of proteins called 'antibodies' which go on to 'attack' healthy tissues. Seizures in AE typically do not respond well to classic 'anti-seizure medications'. Instead, medications which suppress the immune system are used. These can have significant side-effects and some patients will still continue to have seizures or experience a recurrence of AE-related epilepsy despite treatment. It is difficult to accurately predict who will experience these outcomes. This study aims to find ways of predicting and monitoring which people with AE are at greatest risk of these outcomes, so we can better direct them towards appropriate treatments. We will collect clinical information and samples of blood and cerebrospinal fluid (CSF, fluid surrounding the brain and spinal cord) from people with AE and 'control' participants with other neurological illnesses. Samples will be analysed for markers which may help predict or correlate with outcomes in AE and better understand this condition.
