(Ivanhoe Newswire) -- Alzheimer's disease and frontotemporal lobar degeneration (FTLD) are two of the most prevalent forms of neurodegenerative disorders. Researchers have analyzed changes in gene expression in the aging and diseased brain, finding new clues to the biology of normal aging and neurodegenerative diseases. In this report, an international team of researchers analyzed and compared changes in gene expression associated with aging and disease in a region of the brain known to be...

Alzheimer's disease and frontotemporal lobar degeneration (FTLD) are two of the most prevalent forms of neurodegenerative disorders. In a study published online today in Genome Research (www.genome.org), researchers have analyzed changes in gene expression in the aging and diseased brain, finding new clues to the biology of normal aging and neurodegenerative diseases. Recent studies have identified changes in how genes are read, or expressed, in the brain either during aging or with...

Animal study points to changes in brain that might help prevent cognitive decline A small amount of exercise shields older animals from memory loss following a bacterial infection, according to a study in the August 10 issue of The Journal of Neuroscience. The findings suggest moderate exercise may lead to several changes in the brain that boost its ability to protect itself during aging "” a period of increased vulnerability. In the new study, researchers led by Ruth Barrientos, PhD,...

Researchers say that evolution of human longevity led to both a large brain and brain shrinkage. A team of researchers sought to find out if a chimpanzee brain shrinks as much as a human's brain does with old age. Chet Sherwood, an anthropologist at The George Washington University in Washington, D.C., and a team of scientists from seven other U.S. universities used magnetic resonance imaging (MRI) to measure the space occupied by various brain structures in adult humans and chimpanzee....

Researchers at Mount Sinai School of Medicine have published new data on why the aging brain is less resilient and less capable of learning from life experiences. The findings provide further insight into the cognitive decline associated with aging and neurodegenerative diseases like Alzheimer's. The study is published in the May 25 issue of the Journal of Neuroscience. The Mount Sinai team evaluated the prefrontal cortex"”the part of the brain that controls a wide range of cognitive...

Scientists on August 23 reported the first evidence that eating blueberries, strawberries, and acai berries may help the aging brain stay healthy in a crucial but previously unrecognized way. Their study, presented at the 240th National Meeting of the American Chemical Society (ACS), concluded that berries, and possibly walnuts, activate the brain's natural "housekeeper" mechanism, which cleans up and recycles toxic proteins linked to age-related memory loss and other mental decline. Shibu...

UCI researchers locate brain passage that could aid early diagnosisWith the help of volunteers aged 18 to 89, UC Irvine researchers have identified for the first time in humans a long-hidden part of the brain called the perforant path. Scientists have struggled for decades to locate the tiny passage, which is believed to deteriorate gradually as part of normal aging and far more quickly due to Alzheimer's disease."The nice thing about this is we may be able to predict Alzheimer's very early,"...

Specialized brain training targeted at the regions of a rat's brain that process sound reversed many aspects of normal, age-related cognitive decline and improved the health of the brain cells, according to a new study from researchers at University of California, San Francisco. The results indicate that people who experience age-related cognitive decline, including slower mental processing and decreased response to new stimuli, might also benefit from specially designed mental exercises....

The brain undergoes rapid growth and development in the early years of life and then degenerates as we progress into old age, yet little is known about the biological processes that distinguish brain development and aging. In a report published online today in Genome Research (http://www.genome.org), researchers have identified a gene regulatory link between changes in the young and aging brain, describing "runaway" development as a potentially significant factor in age-related loss of...

Researchers at NYU School of Medicine have found that elevated cerebrospinal fluid levels of phosphorylated tau231 (P-tau231), a damaged tau protein found in patients with Alzheimer's disease, may be an early diagnostic biomarker for Alzheimer's disease in healthy adults. The study published this month online by Neurobiology of Aging shows that high levels of P- tau231 predict future memory decline and loss of brain gray matter in the medial temporal lobe- a key memory center. Prior studies...
