There aretypes of SMA. Werdnig-Hoffmann disease, also known as SMA1, is the most severe form. It begins in utero or during the fi rst months of life. SMA type I, the most severe form (Werdnig-Hoffmann disease) can be detected in utero or during the fi rst months of life. Death typically occurs within the fi rstyears of life. It affects the nerve cells controlling the voluntary muscles—the muscles under your conscious control that you can move at will. Infants with this condition experience severe muscle weakness with onset beforemonths of age Type I or Werdnig-Hoffmann disease (WHD) —the most severe form. Death usually occurs before the age ofyears. Symptoms of Werdnig-Hoffmann disease are apparent before agemonths, sometimes as early as birth Spinal muscular atrophy type I, also called Werdnig-Hoffmann disease, is the most serious form. Type II or intermediate —occurs beforemonths of age. It is the most common type of SMA and accounts for about% of individuals with this condition.
