Down Syndrome and Alzheimer's

Although there are more immediate concerns I have for my little girl’s health, Alzheimer’s disease is something else she may face in the future. Studies have shown that genes on the 21st chromosome contribute to the aging process, and therefore an extra copy of 21 increases the risk of a degenerative memory disease.

I am choosing to write about this today because there was a recent conference in Chicago where experts in both Down syndrome and Alzheimer’s met to discuss the link between the two afflictions. In a study funded by Johnson & Johnson, individuals with Down syndrome will be the focus of research since the occurrence of Alzheimer’s is much higher in people with DS (roughly 25% show signs by age thirty, with the rate increasing to as high as 75% with age). 

In the past the life expectancy of an individual with Down syndrome was not much past 30, so the connection was not as evident. Now that individuals are living into their 60s, scientists see an opportunity to study a disease that slowly steals people from their loved ones.

The hope is that by monitoring those with a high risk from an early age (before symptoms manifest), they may able to do better understand the progression and to prevent the causes of Alzheimer’s (brain plaques and tangles). You can read the full article here.

One of the questions posed in the article is if parents of adults with Down syndrome would be willing to sign them up for these studies. I think about what I would do, and I suppose it really depends on what the study would entail. Would it be diagnostics and observations, or more risky drug trials? Would you sign up your son or daughter to be studied?
