Amyotrophic lateral sclerosis (ALS), also called Lou Gehrig’s disease is a motor neuron disorder. It is a neurological disease that attacks the nerve cells (Neurons) in the brain and the spinal cord. These cells are responsible for controlling voluntary muscles (muscle action we are able to control, like those in the arms, legs and face) action.
ALS is a progressive disease to which there is no known cure or remedy, the exact cause of ALS is also unknown. An ALS patient experiences muscle atrophy (reduction of muscle mass) and loses control over actions such as swallowing, breathing and even speaking.
ALS is the most common motor neuron disorder. The USA has a congressionally mandated registry where people suffering from ALS are required to register themselves, this is done to help scientists learn more about the disease.
What happens in ALS
People affected by ALS face degeneration of motor neurons, they are no longer able to send impulses to the muscle fibers that are responsible for muscle movement. Early symptoms of ALS are- increasing muscle weakness, especially in the arms and legs, difficulty in speech, swallowing and even breathing.
When the muscles do not receive the messages from the motor neurons, the muscles begin to lose mass and undergo atrophy (become thinner and smaller). Limbs begin to look thinner and more feeble.
There are no drugs that can heal or treat ALS, but one FDA approved drug Riluzole is known to slow down the progression of the disease and delay its eventualities. People suffering from ALS may not have identical experiences or symptoms, the effect of the disease can be varying and scientist are still collecting data about the many manifestations of the disease.
ALS can affect any part of the body and the atrophy progressively spreads to other parts. Affected people require comprehensive medical attention and a in the latter stages a permanent assistant or help is necessary to assist him/her. ALS patients have to use the Passey-Muir Speaking Valve to speak, as their vocal and thoracic muscles are affected.
The disease came into the limelight in 1987 when three American football players Matt Hazeltine, Bob Waters and Gary Lewis succumbed to ALS. Sports scientists have recently discovered that trauma and head injuries could lead to an ALS like disease. The US Parliament also raised the issue of head injuries that caused concussion and laws to be passed to prevent and treat such injuries in sports and also in the military.
Though ALS is listed as a rare disease it affects more than 100,000 people worldwide and affects people of the 40-60 age group. People of Caucasian origin seem to be affected more than people of other ethnic backgrounds. There have been a rise in cases continued…
