Neurologist

A neurologist is a physician specializing in disorders of the nervous system. Clinical work combines the history and neurological examination with investigations to connect impaired functions to possible anatomical and physiological causes.

The work of neurologist Robert S. Fisher includes the operational definition and classification of epilepsy. He led the international task force responsible for the 2014 practical clinical definition. ^[ref]

The contribution distinguishes an enduring predisposition to seizures from a count of isolated observed events. The report set out circumstances in which recurrence risk or a recognized epilepsy syndrome can support a diagnosis after fewer than two unprovoked seizures. Defining such criteria makes clinical classification reproducible while exposing its assumptions; the diagnostic category is not itself a complete explanation of the underlying neural mechanism.

A neurologist who coauthored experiments testing the contribution of the contralateral inferior frontal gyrus to recovery of language after stroke. Perturbing a region supplied evidence beyond the association between activation and recovery.^[ref]

Neurologist and researcher on language function after stroke.

A neurologist who coauthored clinical research comparing the age of reported dementia onset in bilingual and monolingual groups. The observational association, including adjustment for measured background variables, is distinct from a randomized demonstration that learning a language prevents disease.^[ref]

Neurologist studying cognitive disorders and bilingual experience.

A neurologist who coauthored research relating patterns of cognitive impairment to regional anatomy in variants of primary progressive aphasia. Comparing variants helped connect differences in language function with differences in affected neural systems.^[ref]

Neurologist studying language and primary progressive aphasia.

A neurologist whose work investigates reward, effort and apathy, including experimental choices in Parkinson's disease.

A neurologist whose case reports linked severe loss of spontaneous activity with bilateral basal ganglia injury and relative preservation under external stimulation.

A neurologist whose studies helped characterize semantic dementia as a progressive disorder of conceptual knowledge.

A neurologist whose report of associative visual agnosia examined visual recognition in relation to copying and other accompanying deficits.

A neurologist whose work on aphasia helped motivate anatomical and functional distinctions within language processing. Clinical syndromes bearing his name must still be explained through specific representations and computations.
