About Ice Bucket Challenge:
Ice Bucket Challenge is an attempt to raise awareness of ALS (Amyotrophic lateral sclerosis). The participants dump a bucket filled with ice and then challenge their friends to do the same. On failing to do so, they have to donate $100 to the ALS association.
About ALS:
Amyotrophic lateral sclerosis (ALS), often referred to as “Lou Gehrig’s Disease,” is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. Motor neurons reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body. The progressive degeneration of the motor neurons in ALS eventually leads to their death. When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. With voluntary muscle action progressively affected, patients in the later stages of the disease may become totally paralyzed.
