[Julien Bogousslavsky].

Julien Bogousslavsky is undoubtedly one of the giants of modern neurology. He is best known for creating the Lausanne Stroke Registry and for publishing a considerable number of works on the symptoms and signs caused by cerebrovascular disturbance. Bogousslavsky's research interests extend to the broader field of human cerebral activity, including higher brain function disturbance and even psychiatric symptoms. In this article, his works are introduced according to the following three themes: (1) neurological symptoms and signs caused by a specific lesion in the brain, (2) neurological symptoms and signs caused by a specific cerebrovascular lesion, and (3) psychiatric and/or neuropsychological symptoms caused by organic brain damage.
