Amyotrophic Lateral Sclerosis (Als)

Amyotrophic lateral sclerosis (ALS)

Amyotrophic lateral sclerosis (ALS), roughtimes called Lou Gehrigs disease, is a rapidly progressive, invariably fatal neurological disease that attacks the warmheartedness cells (neurons) responsible for controlling wilful muscles. The disease belongs to a multitude of disorders known as motor neuron diseases, which atomic number 18 characterized by the gradual degeneration and death of motor neurons.
Motor neurons are nerve cells located in the instinct, brainstem, and spinal cord that make out as controlling units and vital communication links surrounded by the nervous system and the voluntary muscles of the body. Messages from motor neurons in the brain (called upper motor neurons) are transmitted to motor neurons in the spinal cord (called lower motor neurons) and from them to particular muscles. In ALS, both the upper motor neurons and the lower motor neurons disruptive or die, ceasing to send messages to muscles. Unable to function, the muscles gradually weaken, waste extraneous (atrophy), and twitch (fasciculations). Eventually, the ability of the brain to start and control voluntary movement is lost.
ALS causes weakness with a wide grip of disabilities. Eventually, all muscles under voluntary control are affected, and patients meet their strength and the ability to move their arms, legs, and body.



When muscles in the diaphragm and thorax wall fail, patients lose the ability to breathe without support from a ventilator. Most people with ALS die from respiratory failure, unremarkably within 3 to 5 years from the onset of symptoms. However, just about 10 percent of ALS patients survive for 10 or more years.
Although the disease usually does not impair a persons mind or intelligence, several recent studies suggest that some ALS patients may have alterations in cognitive functions such as depression and problems with decision-making and memory.
ALS does not affect a persons ability to see, smell, taste, hear, or recognize touch. Patients usually maintain control...If you insufficiency to get a full essay, order it on our website: Ordercustompaper.com
