why the death of Stephen Hawkins
Answers
When he was diagnosed at 21 with a type of motor neurone disease, amyotrophic lateral sclerosis (ALS), Professor Stephen Hawking was given two years to live.
But his death 55 years later has sparked an outpouring of grief from the scientific community and the wider public. It is testament to how he defied the odds, and helped define our understanding of the universe.
Hawking’s intellectual achievements have become almost mythical in the face of the disease which progressively shut down his limbs, confining him to a wheelchair, paralysing his muscles and rendering him unable to speak.
ALS is more accurately a group of conditions, which have the shared characteristic of the gradual degeneration nerve cells in the brain and body – the cells which coordinate our voluntary movement.
This includes walking and moving the arms, but also extends to the core muscles and the diaphragm, which enables us to breathe, and the muscles used for speech and swallowing.
