Professional background

Sofia Eriksson is a consultant neurologist and honorary associate professor at National Hospital for Neurology and Neurosurgery and UCLH and the UCL/Institute of Neurology. She is the hospital’s clinical lead for epilepsy as well as neurological sleep disorders. In 2019 she was elected to the council of the Association of British neurologists (ABN) and is also a member of the ABN’s expert panel for epilepsy and the European Academy of Neurology’s scientific panel for Sleep-Wake disorders.

She started her medical and research career in Göteborg, Sweden before joining the Department of Clinical and Experimental Epilepsy (DCEE) at the Institute of Neurology/UCL in London. She was awarded her PhD in 2003 after which she did a post doc with the DCEE before finalising her specialist training in neurology. She has been working as a consultant at the National Hospital for Neurology and Neurosurgery since 2008.

Her special interests are epilepsy and neurological sleep disorders such as parasomnias and narcolepsy.

Research interests

Parasomnias, particularly investigations and treatment of NREM parasomnias, sleep disorders in neurological conditions, such as epilepsy, dementia and Parkinson’s disease, epilepsy, particularly focusing on brain imaging and histopathology.
