Motor Neurone Disease

Extracts from this document...


Motor Neurone Disease (MND), incurable condition in which the nerves concerned with muscular contraction degenerate progressively. This may affect motor neurones in the brain and in the spinal cord. When the main effect is on the spinal cord (the commonest variety of the disease), the condition is also known as amyotrophic lateral sclerosis (ALS). ...read more.


But 5 to 10 per cent of incidents of the disease are inherited, and in some of these there is known to be a gene defect that alters the function of an enzyme known as super oxide dismutase. Affected muscles twitch, become progressively weaker. The muscles that control eye movement, and sphincter muscles, which surround the openings of organs such as the bowel, are unaffected. ...read more.


There is hoarseness, reduction in the strength of the voice, and wasting of the tongue. Eventually, speech becomes impossible. Lucent Technologies are a company which provide a voice synthesis system. Advances in electronic control and communication and in electromechanical technology have enabled sufferers of the disease to achieve some measure of independence. Control of electrically operated wheelchairs is possible by applying light pressure, blowing, head-nodding, or even blinking. By Peter Hales 10KE ...read more.
