Dr James Stefaniak


I am a neuroscientist and psychiatrist interested in cognition and its impairment following acute (e.g. stroke) and progressive (e.g. dementia) brain damage as well as psychiatric disorders.

Research Focus







Clinical conditions

Alzheimer's disease


Cognitive impairment


Language disorders



Cross-sectional and cohort studies


Magnetic resonance imaging (MRI)
