Samuel Alexander Kinnier Wilson

: Samuel Alexander Kinnier Wilson is considered a pioneer in extrapyramidal system research largely due to his dissertation on progressive lenticular degeneration, later known as "Wilson's Disease". His concept of neurological symptomatology was based on the clinical observations of Pierre Marie, Joseph Babinski and John Hughlings Jackson, who he observed when he was young. To keep focusing on the nature of actual symptoms while performing medical examinations is the essence of neurological symptomatology, which in turn form the spirit of neurology. This paper will discuss major events in Wilson's later life that would explain how his basic idea for neurological symptomatology was eventually formed.
