Muscular dystrophy, polio (poliomyelitis), and primary lateral sclerosis are all motor neuron diseases. Although a universal direct cause has not been found, your brain sends signals to your spinal cord through motor tracts (the" anterolateral system," among others) which go out through nerves through the "ventral horn" to nerves that reach your muscles. A disease that affects motor neurons can be from a defect in your primary motor cortex (brain), any one of the motor tracts in your spinal cord, or in one of the nerves that reaches to your muscles.

It is also known as ALS, my granmother has Shy Drager, a form of it. They have found no cause nor a cure. It sucks. It seems to be mostly found in the elderly but it can start early and get worse over the years. It is a sad disease to watch progress. I sometimes think it it has something to do with exposure, not familial because both my grandparents had it and their symptoms were nearly identical. Who knows.
