Johannes Werdnig

Johannes Werdnig was an Austrian neurologist who, in the early 20th century, first described a genetic disorder now known as Werdnig-Hoffmann disease or spinal muscular atrophy type 1. This inherited condition causes progressive muscle weakness and loss, especially affecting infants and young children. It results from the degeneration of spinal cord nerves that control muscle movement, leading to difficulty swallowing, breathing problems, and limited motor skills. Recognized as a severe and often fatal illness, the disease emphasizes the importance of genetic research and early diagnosis for management and potential future therapies.
