Page 8 Share Cite Suggested Citation: Disease modifying therapy is limited to riluzole if nutrition and respiratory support are excludedand there is no curative treatment. The risk beyond the age of 70 years is uncertain because of difficulties in separating ALS from other conditions Armon ; Mandrioli et al.

Symptoms characteristic of limb-onset can develop simultaneously with bulbar symptoms occurring within 1—2 years. French neurologist Jean-Martin Charcot discovered the disease in Continuous positive pressure is not recommended for people with ALS because it makes breathing more difficult.

There are four other known MNDs: It is also possible that the administration of L-DOPA or the decreased levels of endogenous dopamine could offer an antioxidant protective effect in those susceptible to ALS, similar to that seen in multiple studies comparing ALS incidence and Vitamin E consumption.

ALS usually strikes people between the ages of 40 and 70, and it is estimated there are more than 20, Americans who have the disease at any given time although this number fluctuates. As the diaphragm and intercostal muscles of the rib cage that support breathing weaken, measures of lung function such as vital capacity and inspiratory pressure diminish.

That disruption leads to weakness of muscles in a characteristic pattern and to spasticity. Patients with bulbar symptoms suffer from sialorrhea excessive drooling due to difficulty of swallowing saliva and minor bilateral lower facial weakness from UMN damage.

What is ALS?

Such studies have been used by VA to assist it in developing disability compensation polices for specific groups of veterans Vietnam War veterans and Gulf War veterans. ALS causes degeneration of the motor neurons in the cerebral motor cortex called upper motor neurons and in the brain stem and spinal cord called lower motor neurons Rowland The following types of studies were identified: Physical therapy plays a large role in rehabilitation for individuals with ALS.

Possible associations for which evidence is inconclusive include military service and smoking. There is controversy as to how well cellular and animal models of disease relate to the human disease.Amyotrophic lateral sclerosis is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH).
