Genetics and Alzheimer’s Disease: How do genes affect Alzheimer’s disease?

https://www.youtube.com/watch?v=vYZ1RppCysQ Genes are the building blocks that make us who we are, what we look like, and how we age. Variations in genes — even small changes to a gene — can affect the likelihood of a person developing a disease such as Alzheimer’s. Researchers used to know of only a few genes linked to Alzheimer’s disease. Now, they’ve identified over 70 genetic regions that may play a role. Understanding how genes impact the risk of Alzheimer’s and related dementias helps researchers look for new ways to prevent and treat the disease.
