There are other questions that need to be answered, says Sam Gandy, MD, PhD. He is the Mount Sinai chair in Alzheimer's disease research at Mount Sinai School of Medicine in New York City. "The finding emphasizes one area that we still understand poorly: why some people are very sensitive to amyloid poisoning and lose [mental ability] in the face of relatively low amyloid buildup."

Alzheimer's disease is the most common type of dementia. Symptoms including serious memory loss, confusion, and mood changes that develop gradually and worsen with time.
The findings are published in the journal Neurology.
at early stages to slow disease progression so they don't develop memory loss until age 95?This would be a therapeutic home run," he says.
Dean Hartley, PhD, agrees. He is an associate professor of neurosciences and a neuroscience researcher at Rush University Medical Center in Chicago. The new findings "take us closer to trying to find out when the disease begins, and then we can begin to follow the progression and start to look at drugs," he says.
If there was one thing a person could do to prevent Alzheimer's today, even in the face of amyloid build up, it would be to exercise. "Physical exercise still seems to be the one that has the strongest effect," Gandy tells WebMD.

The amount of beta amyloid in brains increased with advancing age. About20% of adults aged 60 and older had high levels of plaque in their brains. Those who had the highest levels of beta amyloid in their brains had lower scores on tests of their memory, reasoning, and processing. People with greater amounts of Nike Tracksuit Football amyloid were also more likely to be positive for the APOE gene, the study showed.
Researchers from the Center for Vital Longevity at the University of Texas at Dallas looked at the brains of 137 healthy people aged 30 and 89 via PET scans. Participants were also tested for the APOE gene, which has been linked to increased Alzheimer's disease risk.
of neurosurgery and director of the Maxine Dunitz Neurosurgical Institute at Cedars Sinai Medical Center in Los Angeles. He reviewed the findings for WebMD. Black says the new study supports the notion that changes in the brain that lead to Alzheimer's disease may begin years, or even a decade, before a person has symptoms.
Plenty of people can resist amyloid for decades and we would really like to understand why, he says.
