(Ivanhoe Newswire)-- A recent study showed that the protein beta-amyloid which is found in the brain and associated with Alzheimer's disease may even affect the mental function in healthy individuals. "In our study, we observed that even in adults with apparently good cognitive health, increasing amounts of beta-amyloid in the brain are related to subtle changes in memory and mental function," Denise C. Park, PhD, study author, of the Center for Vital Longevity at the University of Texas...

Researchers from the Center for Vital Longevity at the University of Texas at Dallas and UT Southwestern Medical Center have completed a large-scale neuroimaging study of healthy adults from age 30 to 90 that measured beta-amyloid protein–a substance whose toxic buildup in the brain is a diagnostic marker for Alzheimer's disease. The findings, published in the February 1, 2012 online issue of Neurology, the medical journal of the American Academy of Neurology, mark a crucial step...

High levels of the protein beta-amyloid in the brain that is associated with Alzheimer's disease may affect brain performance even in healthy adults, according to a study published in the February 1, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology. "In our study, we observed that even in adults with apparently good cognitive health, increasing amounts of beta-amyloid in the brain are related to subtle changes in memory and mental function,"...

(Ivanhoe Newswire)-- Alzheimer´s disease is ranked the sixth-leading killer in the country, along with an estimated 5.4 million Americans and their families who continually suffer with the disease. A new study led by researchers at the University of California, Berkeley, revealed that individuals with no symptoms of Alzheimer´s disease who participate in cognitively stimulating activities such as reading books, or doing puzzles throughout their lives had fewer deposits of the...

Brain Boosting Activities Early In Life May Cut Later Risk Of Alzheimer’s

A new study suggests that people who engage in mentally stimulating activities such as reading and playing games — particularly early in life -- may be lowering levels of a brain protein linked to Alzheimer's disease. The protein, known as beta-amyloid protein, is the main component of the destructive brain-clogging plaques that are a hallmark of Alzheimer´s disease. Researchers at the University of California Berkeley surveyed 65 healthy elderly people, whose average age was...

A new study led by researchers at the University of California, Berkeley, provides even more reason for people to read a book or do a puzzle, and to make such activities a lifetime habit. Brain scans revealed that people with no symptoms of Alzheimer's who engaged in cognitively stimulating activities throughout their lives had fewer deposits of beta-amyloid, a destructive protein that is the hallmark of the disease. While previous research has suggested that engaging in mentally...

Discovery may lead to better understanding of the disease, possible therapies With a lack of effective treatments for Alzheimer's, most of us would think long and hard about whether we wanted to know years in advance if we were genetically predisposed to develop the disease. For researchers, however, such knowledge is a window into Alzheimer's disease's evolution. Understanding the biological changes that occur during the clinically "silent" stage – the years before symptoms...

Cerebrospinal fluid levels of Aβ42 appear to be decreased at least five to 10 years before some patients with mild cognitive impairment develop Alzheimer disease (AD) dementia whereas other spinal fluid levels seem to be later markers of disease, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals. The researchers note as background in the study that disease-modifying therapies, such as immunotherapy, are more likely to be...

Study provides more evidence linking depression to possible dementia later in life Depression is one of the most common mental disorders in the elderly, but little is known about the underlying biology of its development in older adults. In a small study published in the November issue of the peer-reviewed journal Archives of General Psychiatry, UCLA researchers used a unique brain scan to assess the levels of amyloid plaques and tau tangles in older adults with a type of severe...

Scientists outline new methods for better understanding links between specific proteins and the risks associated with Alzheimer's disease in an article co-authored by University of Alabama researchers and publishing today in Science Express. In experiments using a series of model organisms, including yeast, microscopic roundworms and rats, the researchers show how basic mechanisms inside cells are disrupted when a specific human protein, known as the amyloid beta peptide, fails to properly...
