I wonder if we'll ever truly get to the bottom of what triggers diseases such as Alzheimer's and autism. Is it strictly one's genetic makeup, environmental factors, or both?
Part of tonight's "Nova Sciencenow" at 8 explores the latest research on the genetic basis of autism, by a team that pioneered the search for a gene linked to Alzheimer's. (The photo above shows a woman featured in the program and her son, who is autistic.)
Whether or not vaccines or childhood lead poisoning play a role in causing autism, new genetic research is painting a whole new picture.
The implications are enormous. If conclusive evidence of genetic predisposition is found, people could be diagnosed and treated at an earlier stage. Preventive measures could be taken – and medical treatment sought out before symptoms even surface.
What do you think? Should American taxpayers be helping to pay for genetic studies around autism and other widespread health conditions? Or is this a step down a slippery slope toward creating designer children? What are the implications for society?
We already tend to over-diagnose, over-medicate and see the world through hypochondriac eyes. Meanwhile, some critics say these tests are disturbing the natural process and impeding on how we were each born to be.
But if genetic studies allow for greater understanding of these conditions – and ultimately more thorough treatment and prevention – it may be one of the most important things we as a society get behind.
