SMA Type III (Mild)

 


Diagnosis of Type III, often referred to as Kugelberg-Welander or Juvenile Spinal Muscular Atrophy, is made sometime after 18 months of age and as late as adolescence. The patient with Type III can stand alone and walk, but may show difficulty with walking and/or getting up from a sitting or bent over position. With Type III, a fine tremor can be seen in the outstretched fingers but tongue fasciculations are seldom seen.


PROGNOSIS.....

Patients with Type III will again vary greatly. However, the prognosis is very good. Often walking will be possible, or the patient will be fully functional for years before assistance is necessary. As with Type I and Type II respiratory infections should be presented and necessary precautions taken.
