Imagine a future where an online dating app doesn’t just match you to potential partners who meet your preferences for age, height and fondness for pinot noir, but to those with whom you’re genetically compatible. Not so much people you’re likely to have physical chemistry with – apps that make dubious claims to do that on the basis of a cheek swab already exist – but those with whom you won’t pass on a devastating genetic disease to your children. It’s not sexy stuff; certainly not first-date conversation. Most people only discover that they’re among the four per cent who carry the same recessive genetic mutation for a rare condition, such as cystic fibrosis or Tay-Sachs, as their partner when their baby is born with it – or dies from it. True, couples could find out their genes don’t mix after they’ve decided to have a baby and before they start trying – but how heartbreaking would that be, once they’re … [Read more...] about This Harvard scientist wants your DNA to wipe out inherited diseases

Ninety-seven-year-old Scott Hughes and her identical twin sister Virginia were always close. When Virginia started having trouble with her memory and thinking, Scott knew something wasn't right. Virginia was later diagnosed with Alzheimer's disease. "It was heartbreaking because she was so outgoing and loving," Scott Hughes told CBS News. "She wasn't going to be who she was before. And that is tragic to see in someone you love."With one twin having Alzheimer's and the other healthy, researchers at Duke Eye Center who are studying the link between eye and brain health thought the sisters were a good case to examine. They took images of their eyes and discovered the twin with Alzheimer's disease had significantly decreased blood vessel density in the retina. That finding spurred a new study of more than 200 people."Cognitively normal, healthy individuals do not have these changes in their retina," explained Dr. Sharon Fekrat, an ophthalmologist at Duke Eye Center and author of the … [Read more...] about Could an eye test help detect Alzheimer’s disease?
News / UK and world by Press Association March 7, 2019, 1:28 am Send us a story Sign up to our Daily newsletter Women taking hormone replacement therapy (HRT) in the long-term could have a small increased risk of Alzheimer’s disease, research suggests. Experts behind the study said women should be warned of the potential impact of HRT, but the Royal College of GPs said the findings should not be a cause for alarm. HRT is taken to relieve symptoms of the menopause such as hot flushes and night sweats and comes as tablets, gels, cream and patches. While most experts believe it is a safe treatment, long-term use has been linked to a small increased risk of blood clots, breast and womb cancer. For the new study, experts examined the use of HRT in 84,739 postmenopausal women in Finland diagnosed with Alzheimer’s disease between 1999 and 2013, and compared them with 84,739 postmenopausal women without Alzheimer’s. Almost all of the women with … [Read more...] about HRT linked to ‘slight increased risk’ of Alzheimer’s disease

A new study of more than half a million children has found no link between the measles, mumps and rubella vaccination and autism. The Danish study, published in the Annals of Internal Medicine journal today, looked at all children born in the country between 1999 and 2010. The children were followed through to the end of August 2013. It found the MMR vaccine did not increase the risk of autism, even in children with other autism risk factors or in children whose siblings had autism. There was also no clustering of autism cases following vaccination. Researchers from Statens Serum Institut in Copenhagen found that of the 657,461 children included in the study, only 6517 were diagnosed with autism. Of the children followed, 95 per cent received the first vaccination, which is offered at 15 months, but there was no difference in the number of vaccinated children with the disorder compared to the number of unvaccinated children. Claims of a link between the MMR vaccine and autism continued … [Read more...] about New study further discredits link between vaccine, autism
