Amyotrophic lateral sclerosis ALS is a progressive neurological disease characterized by the destruction of nerve cells neurons that are responsible for controlling voluntary muscle movement. ALS can affect people of any age though it usually strikes in late middle age.

The most famous example of this is the brilliant physicist Stephen Hawking who was diagnosed in his twenties and has defied the odds to live to his present age of 75.
When does als start. Theres generally no pain in the early stages of ALS and pain is uncommon in the later stages. Other individuals first notice changes in voice and speech spasms in muscles of the jaw face voice box throat and tongue and inappropriate excessive laughing and. Slurred and nasal speech.
There is currently no cure. As far as I know with real ALS once they start they dont stop until the muscle is gone. Therefore an investigation of the molecular abnormalities that occur specifically in the pathological tissues of patients with spo-.
ALS typically announces itself with persistent weakness or spasticity in an arm or leg 80 percent of all cases causing difficulty using the affected limb. The rate of progression between individuals is variable and the history generally reflects gradual and progressive worsening over time until death occurs. ALS is a relentlessly progressive disorder.
The disease often begins with muscle weakness. Muscles may be weak. When symptoms begin in the arms or legs it is referred to as limb onset ALSMND.
Sometimes the initial problem can be one of slurred speech or trouble swallowing. Most people with ALS die within five years usually due to respiratory failure. This may manifest in the feet or the cants and it may affect both sides to a different degree or severity.
Stages of ALS. The risk of developing ALS is partly genetic and partly environmental. The people afflicted progressively lose their ability to move to speak to eat and finally to.
With ALS you may first have weakness in a limb that develops over a matter of days or more commonly a few weeks. Thats whats happening with me. Approximately 10 of cases of ALS are familial and a number of causative genes have been identified1 Many of the causative genes encode proteins that accumulate in cells in ALS.
ALS often starts in the hands feet or limbs and then spreads to other parts of your body. ALS phenotype in familial ALS that have been identified to date. Twitching and cramping of the muscles especially those in the hands and feet muscle weakness in the arms or legs loss of motor control in the arms or legs.
As ALS progresses though more and more symptoms are noticed. For many individuals the first sign of ALS may appear in the hand or arm as they experience difficulty with simple tasks such as. According to the ALS association in fact muscle weakness is the first sign of the disease in 60 percent of patients.
Then several weeks to months later weakness develops in another limb. As the disease advances and nerve cells are destroyed your muscles get weaker. This eventually affects chewing swallowing speaking and breathing.
Difficulty chewing or swallowing. Muscle weakness affecting an arm a leg neck or diaphragm. Amyotrophic lateral sclerosis ALS is characterised by progressive muscle weakness and degeneration of upper and lower motor neurones.
A-myo-trophic comes from the Greek language. ALS can start off with something as simple as a weak feeling in your hands or feetIts a disease that attacks the brain cells that control a lot of your muscle movement. In ALS the neurons that control muscles start to die off one by one.
They tell me my ALS is. The early onset of ALS is often very subtle - these are the first Symptoms of ALS to watch for. We hypothesize that a progressive downregulation of ADAR2 activity plays a critical role in the pathogenesis of sporadic ALS and that the pathological process commences when motor neurons express unedited GluA2.
Examples of voluntary muscle movement include chewing walking talking and breathing. Amyotrophic lateral sclerosis ALS also known as Lou Gehrigs Disease is a disease that affects parts of the nervous system that control voluntary muscle movements the muscles that people move at will like those of the arms and legs. We hypothesize that a progressive downregulation of ADAR2 activity plays a critical role in the pathogenesis of sporadic ALS and that the pathological process commences when motor neurons express unedited GluA2.
It is likely therefore that the expression of unedited GluA2 causes the death of motor neurons in sporadic ALS. Although ALS typically manifests between the ages of 40 and 70 younger people can develop it as well.
