Unlike my otherwise light and yummy posts, this one is a bit different and serious in nature for reasons of its own.
Motor neurons starting from the brain travel to the spinal cord and from the spinal cord to the muscles throughout the body. Due to the progressive degeneration the motor neurons in ALS eventually die.
When the motor neurons die, the brain loses its ability to initiate and control muscle movement. With voluntary muscle action progressively affected, the disease in its later stages may lead to patients becoming totally paralyzed.
Other following symptoms include trouble swallowing, cramping; and/or slurred and nasal speech.
The parts of the body affected by early symptoms of ALS are dependent on motor neurons in the body that are damaged first.
Since only motor neurons are attacked by ALS, the sense of sight, touch, hearing, taste and smell are not affected.
Sporadic (most common form in the US)
Guamanian (observed in Guam and the Trust Territories of the Pacific in the 1950's).
Familial (occurs more than once in family lineage)
As per the rule of this challenge, within 24 hours of being challenged, participants have to record a video of themselves in continuous footage. Starting from announcing their acceptance of the challenge followed by pouring ice into a bucket of water to the bucket being lifted and poured over the participant's head. Then the participant can call out a challenge to other people.
The people who refuse to perform the challenge then donate to the cause.
