Una nueva prueba podrí­a predecir si los problemas de memoria se convertirán en Alzheimer

In English- Una prueba de sangre que puede predecir si alguien que tiene problemas de memoria desarrollará  la enfermedad de Alzheimer podrí­a estar disponible en un plazo de tan solo dos años, anunciaron investigadores británicos. Al analizar a más de 1,000 pacientes -y realizarles resonancias magnéticas del cerebro a 467- investigadores de King’s College en Londres descubrieron una combinación de 10 proteí­nas que parecen predecir con una exactitud del 87% si las personas con problemas cognitivos leves podrí­an desarrollar el mal de Alzheimer total …

New Test Could Predict Whether Memory Problems Will Become Alzheimer’s

A blood test that can predict whether someone with memory problems will develop Alzheimer’s disease may be available in as little as two years, British researchers announced today. By analyzing more than 1,000 patients – and performing MRI brain scans on 467 – researchers at King’s College in London discovered a combination of 10 proteins that seem to predict with 87 percent accuracy whether people with mild cognitive impairment will develop full-blown Alzheimer’s within a year. Because the research, which was published in …

Major New Study Tests Drug to Prevent Alzheimer’s Disease

In what some experts are calling the most important Alzheimer’s research of the decade, scientists at 61 medical centers across the country and elsewhere have launched a groundbreaking study to test whether an experimental new medication can protect healthy older adults from the memory loss and brain damage caused by the disease.  “Our best chance of really changing the disease is to start treatment before people have symptoms,” said lead researcher Reisa Sperling, professor in neurology at Harvard Medical School and director of the …

Learning a Second Language at Any Age Can Slow Brain Aging

I lived in Stockholm for two years after college and doggedly learned Swedish, even though most Swedes speak beautiful English. Not only could I communicate better with then-tiny (now giant) Swedish nephews, turns out it was a good move for my brain. Learning a second language – even as an adult – helps protect the brain from aging,  says a new study published in the Annals of Neurology. “Learning a language later in life is a challenge but is very, very good for …

Calling All Cynics: Your Mistrust Is Bad for Your Brain

If you’re a cynic, you’ll probably disregard this, but researchers say that cynical mistrust will triple your risk of developing dementia. Scoff all you want, but researchers in Finland who tested 1,449 older adults (average age: 71) found that highly cynical people were three times more likely to develop dementia than those with a more trusting, optimistic personality, according to a study published today in the journal Neurology. In other words, “your personality may affect your brain health,” explained lead …

Can Young Blood Reverse Aging in Older Brains?

What’s the secret of youth? It may be all in the blood. Three new studies published Sunday showed that when the blood of young mice was put into the systems of older mice, the effects of aging were reversed, improving both muscles and brains. Researchers will now race to find practical implications for older human brains. One of the study authors plans to start a trial this year, giving young blood to Alzheimer’s patients to see if it can reverse …
