Men at Higher Risk for Mental Decline That Precedes Alzheimer's

  • PDF
WEDNESDAY, Jan. 25 (HealthDay News) -- Subtle problems with memory and thinking skills -- known as mild cognitive impairment -- often precede Alzheimer's disease, and a new study finds that men are at higher risk for these troubles than women.

Lead researcher Rosebud Roberts and her colleagues looked at 1,450 people from Olmsted County, Minn., who were between 70 and 89 years old and free of dementia in October 2004. Some three and a half years later, 296 had become mildly impaired.

New cases of...

Steady Diet of Mental Stimulation Might Reduce Alzheimer's Risk

  • PDF
MONDAY, Jan. 23 (HealthDay News) -- People who engage in activities such as reading and playing games throughout their lives may be lowering levels of a protein in their brains that is linked to Alzheimer's disease, a new study suggests.

Although whether the buildup of the protein, beta amyloid, causes Alzheimer's disease is debatable, it is a hallmark of the condition, the researchers noted.

"Staying cognitively active over the lifetime may reduce the risk of Alzheimer's by preventing...

NIH-supported revision addresses early brain changesJanuary 18, 2012

WHAT: The neuropathology guidelines used since 1997 to diagnose Alzheimer’s disease at autopsy have been updated to reflect a deeper understanding of Alzheimer’s and other dementias. The effort, a project of the NIH and the Alzheimer’s Association, will help pathologists characterize Alzheimer’s-related brain changes at death in people diagnosed with dementia and those who have not yet shown clinical symptoms, taking...

Left unchecked, the number of Alzheimer's patients could triple by 2050, experts say

WEDNESDAY, Jan. 18 (HealthDay News) -- With the Alzheimer's epidemic predicted to reach crisis proportions as the U.S. population ages, a panel of experts is meeting for two days to draft a plan to combat a disease that is fast emerging as one of the nation's biggest -- and costliest -- health threats.

The goal of the plan is to improve diagnosis, buttress support and training programs for families with a...

About Alzheimer's Disease: Causes

  • PDF
Scientists don’t yet fully understand what causes Alzheimer's disease, but it has become increasingly clear that it develops because of a complex series of events that take place in the brain over a long period of time. It is likely that the causes include some mix of genetic, environmental, and lifestyle factors. Because people differ in their genetic make-up and lifestyle, the importance of any one of these factors in increasing or decreasing the risk of developing Alzheimer's differs...
