The U.S. Food and Drug Administration granted 23andMe authorization to offer ten genetic health risk reports including late-onset Alzheimer’s disease, Parkinson’s disease, celiac disease, and a condition associated with harmful...

Mounting evidence points to brain trauma as a risk factor for mental decline. Football players who’ve had multiple concussions perform worse on tests of brain function and are more likely...

Editor’s note: This post has been edited from its original to reflect changes in our product. This past summer researchers announced they’d discovered a rare genetic variant that may be...

In honor of World Alzheimer’s Day, we’re linking to a few posts and stories about the disease. Alzheimer’s disease is the most common form of dementia and affects more than...

23andMe founder and CEO Anne Wojcicki talks about new research into genetic factors correlated with risk for degenerative brain disease in response to traumatic brain injury.

Last month we wrote about the challenging search for genetic influences on human longevity, touching on two of the most recent studies as examples of how elusive solid findings have been. Here, we review the latest genetic findings on longevity and conduct follow-up analyses in the 23andMe database. What we found indicates there's still a long way to go in defining a predictive genetic model for longevity.

Understanding Alzheimer’s disease, the most common cause of dementia in people 65 years and older, is of the utmost importance as the population of the United States (and many other...

Despite years of effort and millions of dollars in research funding, only one gene, APOE, has been conclusively associated with Alzheimer’s disease risk so far.   But now the results...
