###Human: Kindly tell me whether the cramps I am experiencing are due to ALS or MND. ###Assistant: Hello. Your symptoms are not typical of ALS (amyotrophic lateral sclerosis). You should know that at your age ALS is a very exceptional diagnosis. But there are also a lot of other conditions that may mimic this clinical situation. For this reason, I would recommend performing some tests. Complete blood count for anemia, blood electrolytes for possible imbalances, thyroid hormone levels for thyroid dysfunction, vitamin D levels and vitamin B12 levels for a possible deficiency, nerve conduction studies would help exclude ALS and calm your anxiety.
