Diagnosis requires a<unk> ogical examination. A<unk> maging exam can also be helpful for diagnosis. For example, an MRI can be used to discover the atrophy of the specific brain regions. MMND can be differentially diagnosed from similar conditions like Fazio-Londe syndrome and amyotrophic lateral sclerosis, in that those two conditions don't involve sensorineural hearing loss, while MMND, Brown-Vialetto-Van Laere syndrome (BVVLS), Nathalie syndrome, and Boltshauser syndrome do. Nathalie syndrome does not involve lower cranial nerve symptoms, so it can be excluded if those are present. If there is evidence of lower<unk><unk>  involvement, Boltshauser syndrome can be excluded. Finally, if there is a family history of the condition, then BVVLS is more likely, as MMND tends to be sporadic. Classification<unk>  (MMND) is a<unk><unk><unk>  affecting primarily lower<unk><unk> s. 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<unk>  (FMMND). Using this method, cases in which the<unk>  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 by additional optic atrophy. Due to the rareness of MMND, it is classified as an orphan<unk> .
