- Try building your search one term at a time, and be as specific as you can! Search term example: "chronic cough".
- Do not enter multiple findings such as "anemia, chronic cough, weight loss, vomiting" all at the same time.
- After selecting your term from the search results a list of possible diagnoses will be generated. If the list is too long, you will be able to narrow it down by entering additional terms.
- Do not enter values such as "heart rhythm 110" or "sodium 125", instead use "tachycardia" or "hyponatremia".

- Definition
-
A group of disorders marked by progressive degeneration of motor neurons in the spinal cord resulting in weakness and muscular atrophy, usually without evidence of injury to the corticospinal tracts. Diseases in this category include Werdnig-Hoffmann disease and later onset SPINAL MUSCULAR ATROPHIES OF CHILDHOOD, most of which are hereditary. (Adams et al., Principles of Neurology, 6th ed, p1089)
