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 …

For Some Parents, Every Day Is Memorial Day

In World War II, families learned of a loved one killed in action by telegram. My husband’s grandfather, with two military sons, recalled watching the telegram delivery man ride his bike down the street and praying that he would not stop at his door.

In that instant, life changes, leaving parents, …

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 …

Sleep Patterns in Midlife Can Affect Memory Later

Like most Americans, I rarely get the doctor-recommended eight hours of sleep every night. Usually, I get too little sleep. Occasionally, I get too much. So I worried when I saw a new study that found that how much women sleep in middle age can affect their memory later in life. Researchers at Brigham and Women’s Hospital in Boston evaluated the link between sleep duration and memory in more than 15,000 women age 70 and older who were  stroke and …
