Your Brain On... ALS
Your Brain On
Genetic and Environmental Factors in ALS
This chapter explores the genetic underpinnings of ALS, focusing on key genes that impact neuron health and their relation to other neurodegenerative disorders. It also investigates environmental toxins potentially linked to ALS, highlighting the importance of continued research to clarify these connections.
ALS, a nervous system disease, ruled the headlines in the summer of 2014 thanks to the viral Ice Bucket Challenge. How has our knowledge of the disorder evolved a decade later?
Amyotrophic lateral sclerosis, also known as ‘Lou Gehrig's disease’ (named after the iconic baseball player), is a progressive neurological disorder which breaks down a person’s motor neurons. The main symptoms are muscle weakness and impaired physical function — mild, at first, but in the latter stages of the disease’s progression, essential processes like breathing begin to fail.
Most individuals face a life expectancy of two to five years. A small percentage live five to ten years. And an even tinier group survive beyond a decade. Most famously, renowned physicist Stephen Hawking survived more than 50 years past his diagnosis, in part due to the intensive care he was able to afford.
In this episode of the ‘Your Brain On...’ podcast, we discuss:
• What ALS is, and how it affects the brain and the body
• The onset and progression of ALS, from the earliest symptoms to the end-stage impacts
• How ALS patients are diagnosed, treated, and cared for
• Likely causes of ALS, including genetic predispositions and potential environmental risk factors
• How new technologies are rapidly accelerating our understanding of ALS, especially in genetics
Joining us for this installment of the show are two world-class experts on the disease:
• Professor Ammar Al-Chalabi PhD, Professor of Neurology and Complex Disease Genetics at the Maurice Wohl Clinical Neuroscience Institute at King's College.
• Merit Cudkowicz, Director of the Sean M. Healey & AMG Center for ALS at Massachusetts General Hospital.
‘Your Brain On’ is hosted by neurologists, scientists and public health advocates Ayesha and Dean Sherzai.
