Professional background

Professor Rohrer graduated from the University of Cambridge with a first class degree in natural sciences before studying medicine at the University of Oxford and University College London.

He trained in general medicine at the Hammersmith and Whittington hospitals (MRCP 2004), and in neurology at the Royal Free Hospital and National Hospital for Neurology and Neurosurgery. He is now an MRC clinician scientist and honorary consultant neurologist at the National Hospital for Neurology and Neurosurgery.

He runs a weekly specialist cognitive disorders clinic where he has a particular interest in young onset and genetic dementias, and a fortnightly general neurology clinic. He also has an interest in acute neurology and sees neurological referrals at University College Hospital.

Research interests

Professor Rohrer's research focuses on the neuroimaging of frontotemporal dementia (FTD), particularly in relation to its underlying genetic causes.

Research in the field of FTD has led to the publication of over 200 Pubmed-referenced papers and he has spoken at a number of international conferences about his work.

He co-ordinates the Genetic FTD Initiative, GENFI, a multicentre cohort study of presymptomatic genetic FTD (, and has been the clinical lead for the International FTD GWAS Consortium.

He has also set up FTD UK, an annual scientific meeting of UK researchers who work in the FTD field (running since 2011), and runs a website dedicated to providing research updates to the general public about FTD: FTD talk. He is also involved in running a support group for individuals from families where there is a genetic cause for FTD (
