It has been reported that some patients have been misdiagnosed with Spinal Muscular Atrophy, when in fact the correct diagnosis in their specific case was Motor Neurone Disease (MND).
Motor neuron disease is a progressive disease, and most patients die within 2-3 years of diagnosis. There is no cure for MND but treatments and exercises to help maintain a good quality of life and extending mobility period. There is no test that can diagnose MND but other tests can be done to eliminate other similar conditions. Nerve conduction studies can help assess how well the nerves are working and the extent of damage. EMG can also be done to check muscle strength and function.
