What is the outlook for Motor Neuron Diseases ?
Prognosis varies depending on the type of MND and the age of onset. Some MNDs, such as primary lateral sclerosis and Kennedy disease, are not fatal and progress slowly. Patients with spinal muscular atrophy may appear to be stable for long periods, but improvement should not be expected. Some MNDs, such as ALS and some forms of spinal muscular atrophy, are fatal.
