In 1963, he was invited by Prof
Harold Scarborough to spend a year at the
Welsh National School of Medicine in
Cardiff. He joined the research staff of the
University College,
Ibadan in 1964, as a medical research fellow. However, upon gaining a
Smith and Nephew fellowship, he went abroad for further studies under the direction of Henry Miller and John Walton, both eminent neurologists in
Newcastle upon Tyne. After spending some time in Newcastle, he took a job at the
National Hospital for Nervous Diseases, Queens Square,
London before returning to Nigeria in 1965. It was at the
University of Ibadan he launched a productive career, working on
neuro-epidemiology and clinical and investigative
neurology especially the study of
dementia among Nigerians and
African Americans. He then mapped out the
epidemiology of the
neuropathy and was able to study the basic aspects of the neuropathy. He discovered the disease was due to cyanide intoxication. At the time, little was done beyond clinical attention to the disease. His success in discovering the basis of tropical ataxic neuropathy earned him local and international acclaim in the medical community. ==Publications==
