History of Leigh Syndrome

Will, USA

History of Leigh Syndrome

Leigh syndrome is named after Dr. Denis Leigh, a neuropathologist in London, who first described the condition in 1951. It is characterized by specific brain lesions, which are a unique feature of the condition. These lesions typically appear in the basal ganglia, brainstem, and cerebellum. The affected areas often exhibit bilateral symmetrical necrotic or degenerative changes. These distinctive lesions are one of the key diagnostic markers used in identifying it.
