New research published in the December 21 online issue of Neurology reveals that brain size may predict early risk for Alzheimer's disease.
The study showed that 21 percent of those at high risk for Alzheimer's disease, as determined by the smaller size of certain parts of their brains, experienced cognitive decline during three years of follow-up after an MRI scan, compared to 7 percent of those at average risk and none representing low risk.
"The ability to identify people who are not showing memory problems and other symptoms but may be at a higher risk for cognitive decline is a very important step toward developing new ways for doctors to detect Alzheimer's disease," said Susan Resnick, with the National Institute on Aging in Baltimore, who wrote an accompanying editorial to the study.
Alzheimer's typically affects senior citizens with some baby boomers and those on the verge old age exhibiting early warning signs of the disorder. There is no cure for Alzheimer's and the ailment can worsen over the years. Elderly people who are concerned about the financial situation of their family and loved ones may want to purchase life insurance coverage to offset that burden should something unforeseen happen to them.
