The first to be discovered was TDP-43 protein,No test can provide a definite diagnosis of ALS, although the presence of upper and lower motor neuron signs in a single limb is strongly suggestive.The diagnosis of ALS is based on the El Escorial Revised criteria and the Awaji criteria.The El Escorial Revised criteria are specific for ALS, which means that someone who meets the criteria is very likely to have ALS; however, they are not especially sensitive for ALS, which means that someone who does not meet the criteria can still have ALS.

The Awaji criteria have better sensitivity than the El Escorial Revised criteria, especially for bulbar-onset ALS.Because symptoms of ALS can be similar to those of a wide variety of other, more treatable diseases or disorders, appropriate tests must be conducted to exclude the possibility of other conditions.Based on the person's symptoms and findings from the examination and from these tests, the physician may order tests on blood and A number of infectious diseases can sometimes cause ALS-like symptoms,ALS must be differentiated from the "ALS mimic syndromes", which are unrelated disorders that may have a similar presentation and clinical features to ALS or its variants.Most cases of ALS, however, are correctly diagnosed, with the error rate of diagnosis in large ALS clinics being less than 10%.There is no cure for ALS. This led to the discovery in 2008 that mutations in Other names for ALS include Charcot's disease, Lou Gehrig's disease, and motor neurone disease.ALS is sometimes referred to as "Charcot's disease" because Jean-Martin Charcot was the first to connect the clinical symptoms with the pathology seen at autopsy. Descriptions of the disease date back to at least 1824 by ALS itself can be classified in a few different ways: by how fast the disease progresses (slow vs fast progressors), by whether it is inherited or sporadic, and by where it starts.ALS can be classified by the types of motor neurons that are affected.

The illness spread quickly throughout the settlement.Higher resolution videos are available to full members. Flail arm syndrome and flail leg syndrome are often considered to be regional variants of PMA because they only involve lower motor neurons. Login or Comments are attached to the specific sign variation for a word. Most people eventually are not able to walk or use their hands and arms, lose the ability to speak and swallow food and their own saliva, and begin to lose the ability to cough and to breathe on their own.Disease progression tends to be slower in people who are younger than 40 at onset,Difficulties with chewing and swallowing make eating very difficult and increase the risk of choking or of aspirating food into the lungs.

A 2006 randomized controlled trial found that NIV prolongs survival by about 48 days and improves quality of life; however, it also found that some people with ALS benefit more from this intervention than others.

These regional variants of ALS cannot be diagnosed at the onset of symptoms; a failure of the disease to spread to other spinal cord regions for an extended period of time (at least 12 months) must be observed.Flail arm syndrome, also called brachial amyotrophic diplegia,ALS can also be classified based on the age of onset.
