Professional background

Dr Foulkes qualified from the University of Oxford Medical School in 2006, with a 1st class degree in Physiology and an intercalated DPhil (PhD) on the neurophysiology of 3D vision. His postgraduate training in neurology was in Oxford, East Kent and London. He undertook a clinical research fellowship in cognitive neurology at the UCL Dementia Research Centre, working primarily with patients with young-onset Alzheimer's disease and advanced structural MR imaging techniques.

Dr Foulkes runs a cognitive disorders clinic at the National Hospital for Neurology and Neurosurgery in which he sees all types of young-onset dementias. He has a particular interest in young-onset Alzheimer's disease and posterior cortical atrophy. He is involved in clinical trials in Alzheimer’s disease at the UCL Dementia Research Centre. Dr Foulkes also runs a general neurology clinic at the National Hospital for Neurology and Neurosurgery, as well as general neurology clinics at Watford General Hospital and St Albans City Hospital.
