The pathologic hallmarks of the disease include pallor of the corticospinal tract due to loss of motor neurons, presence of ubiquitin-positive inclusions within surviving motor neurons, and deposition of pathologic aggregates.[uniprot.org]
Musclestwitch (called fasciculations). Muscle tone typically increases, and muscles tend to become stiff and tight, leading to muscle spasms (called spasticity). Movements are stiff and clumsy.[msdmanuals.com]
The earliest symptoms include muscletwitching, cramping, stiffness, or weakness. Affected individuals may develop slurred speech (dysarthria) and, later, difficulty chewing or swallowing (dysphagia).[ghr.nlm.nih.gov]
Some of the early symptoms include: fasciculations (muscletwitches) in the arm, leg, shoulder, or tongue muscle cramps tight and stiff muscles (spasticity) muscle weakness affecting an arm, a leg, neck or diaphragm. slurred and nasal speech difficulty[rxlist.com]
Within 15 months, she also described difficulty in writing, weakness of the right hand and arm, and diffuse muscletwitching with painful muscle cramps. Assessment confirmed weakness of all limbs, more marked on the right side, with muscle atrophy.[aafp.org]
Muscle tone typically increases, and muscles tend to become stiff and tight, leading to musclespasms (called spasticity). Movements are stiff and clumsy. In some people, muscle tone decreases, making the limbs seem loose and floppy.[msdmanuals.com]
Baclofen may reduce musclespasms in some patients. Patients troubled by leg cramps may benefit from quinine compounds.[rarediseases.org]
Alex Parker's team is already actively testing drugs that have been previously approved by the US Food and Drug Administration for treatment of such disorders as rheumatoid arthritis, to see if they work with ALS.[nouvelles.umontreal.ca]
Various other tests, including blood and urine tests, x rays, and CT scans, may be done to rule out other possible causes of the symptoms, such as tumors of the skull base or high cervical spinal cord, thyroid disease, spinal arthritis, lead poisoning[medical-dictionary.thefreedictionary.com]

This allows us to administer treatment very early in the worm's life. But ALS is a disease of aging, which usually appears in humans around the age of 55.[nouvelles.umontreal.ca]
Background: The average time from symptom appearance to ALS diagnosis is 1 year, resulting in a detrimental delay in initiation of treatment and potentially precluding patients from enrolling in clinical trials.[neurology.org]
[…] and support There is no cure for motor neurone disease, but treatment can help reduce the impact the symptoms have on your life.[nhs.uk]
This cautious approach is understandable, given the prognosis of the illness and the devastation that being given the diagnosis may cause to a person's life.[patient.info]

Multidisciplinary clinics 17 and noninvasive ventilation for those with respiratory failure ameliorate the prognosis slightly.[touchneurology.com]
Age at diagnosis continues to be the strongest predictor of prognosis; recall case reporting bias may play a role in estimates of survival time.[raredr.com]
Alternative treatment Given the grave prognosis and absence of traditional medical treatments, it is not surprising that a large number of alternative treatments have been tried for ALS.[medical-dictionary.thefreedictionary.com]

ALS is extremely rare, and the diagnostic odyssey can be rather arduous because other masquerading conditions or explanations often must be ruled out before ALS is formally diagnosed. 1, 2 The etiology or cause of nerve cell destruction in ALS remains[mybiosource.com]
Etiology ALS may have a multifactorial etiology or may result from a number of different neuronal insults. The major lines of investigation include genetic, viral, autoimmune 11 and neurotoxic hypotheses.[aafp.org]
Prognosis is poor; previous estimates of median survival from disease onset to death range from 20 to 48 months.[ 1 – 3 ] In most cases etiology is unknown, although a small proportion of cases appear to be of genetic origin.[ 4 ] A recent estimate of[raredr.com]
