Acquired nucleic acid changes may trigger disease onset in sporadic ALS. ALS typically progresses to death in years, usually from respiratory complications 5.

Fasciculation in amyotrophic lateral sclerosis: ALS symptoms in the early stages of the disease can be similar to those of a wide variety of other, more treatable diseases or disorders.

Molecular pathways of motor neuron injury in amyotrophic lateral sclerosis. Future studies of risk factors in ALS need to be designed to precisely quantify active and passive smoking, to ensure that other putative risk factors confer a risk that is independent of their association with smoking.

In later stages of the disorder, aspiration pneumonia can develop, and maintaining a healthy weight can become a significant problem that may require the insertion of a feeding tube.

Risk factors operate upstream to a putative biochemical transformation likely an acquired nucleic acid or protein changewhich causes the appearance of altered proteins or nucleic acids or abnormal quantities of normal proteins or nucleid acids.

They can recommend aids such as computer-based speech synthesizers that use eye-tracking technology and can help people develop ways for responding to yes-or-no questions with their eyes or by other nonverbal means.

Wikimedia Commons has media related to Amyotrophic lateral sclerosis. High school football and risk of neurodegeneration: If people with ALS or their family members are reluctant to discuss end-of-life issues, it may be useful to use the introduction of gastrostomy or noninvasive ventilation as an opportunity to bring up the subject.

Researchers are investigating a number of possible causes such as exposure to toxic or infectious agents, viruses, physical trauma, diet, and behavioral and occupational factors. ALS as a whole is best thought of as a disease showing complex inheritance. Molecular and cellular pathways of neurodegeneration in motor neurone disease.

No cure for ALS is known. They eventually lose the ability to breathe on their own and must depend on a ventilator. From Adams et al. Most people with ALS die from respiratory failure, usually within 3 to 5 years from when the symptoms first appear.

Amyotrophic Lateral Sclerosis

ALS is a motor neuron diseasealso spelled “motor neurone disease”, which is a group of neurological disorders that selectively affect motor neuronsthe latera, that control voluntary muscles of the body.

In much of the world, rates of ALS are unknown. An alternative trigger for disease onset might be appearance of a misfolded intracellular protein that induces other proteins to misfold, with cell-to-cell transmission of the misfolded protein within the motor network. Stiff musclesmuscle twitchinggradually worsening weakness [2]. Non-ATG-initiated translation directed by microsatellite expansions. Disease onset is usually after the age of 50 and the process is usually fatal within 3 to 6 years.


The majority of cases are sporadic and thus less well understood. Clinical Neurology and Neurosurgery. However, there are treatments available that can help control symptoms, prevent unnecessary complications, and make living with the disease easier.
