Madras motor neuron disease disease. Madras motor neuron disease (MMND) is a motor neuron disease affecting primarily lower motor neurons. It is similar to Monomelic amyotrophy and primarily affects young adults in southern India. Authors of a large case study, published in 2008, proposed that MMND be divided into two categories: spontaneously-arising MMND and Familial Madras Motor Neuron Disease (FMMND). Using this method, cases in which the disease is inherited would be categorized as FMMND, while cases that displayed no genetic linkage would be categorized as spontaneously-arising MMND. According to the same study, there is a variant form known as MMNDV, which is classified
