Alexander Leff is a Professor of Cognitive Neurology, a consultant neurologist at the UCL Queen Square Institute of Neurology and an NIHR research professor.

His focus primarily involves brain imaging studies of people with aphasia and alexia, and web-based therapies for patients with cognitive, language or visual impairments.

Professor Leff is also the Chief Investigator on the Gotcha! study, designed to help people with dementia get lots of practice in order to retrieve the names of people who are important to them.

Biography

Lasting language dysfunction is among the most feared and disabling symptoms complicating stroke, yet there is little in the way of an evidence base for its treatment. This is because the mechanisms underpinning recovery from language disorders are not understood and trial interventions are generally not tested within rigorously designed studies. Professor Alexander Leff's work is aimed at filling in both these knowledge gaps simultaneously by combining modern trial-based methodology with functional imaging techniques so that the neural correlates of therapy driven recovery can be identified. His work is split between two common post-stroke syndromes: generalized language dysfunction (aphasia) and isolated reading dysfunction (alexia).
