Mild cognitive impairment, dementia, and their subtypes are common in the "oldest old" women, which includes those 85 years of age and older, according to a report in the May issue of Archives of Neurology, one of the JAMA/Archives journals. The oldest old is "the fastest growing segment of the U.S. population and is expected to increase in number by 40 percent during the next decade alone," the authors write as background information in the article. "Initial evidence suggests that the...

Breakthrough may aid treatment of learning impairments, strokes, tinnitus and chronic pain In a breakthrough that may aid treatment of learning impairments, strokes, tinnitus and chronic pain, UT Dallas researchers have found that brain nerve stimulation accelerates learning in laboratory tests. Another major finding of the study, published in the April 14 issue of Neuron, involves the positive changes detected after stimulation and learning were complete. Researchers monitoring brain...

Older adults with hearing loss appear more likely to develop dementia, and their risk increases as hearing loss becomes more severe, according to a report in the February issue of Archives of Neurology, one of the JAMA/Archives journals. By the year 2050, an estimated 100 million people or nearly one in 85 individuals worldwide will be affected by dementia, according to background information in the article. Interventions that could delay the onset of dementia by even one year could lead to a...

Dementia and cognitive impairment are widespread among elderly individuals in the United States, affecting more than 8 million people to some degree. The Sweet 16, a new screening test developed by a team of geriatricians and neurologists at the Institute for Aging Research of Hebrew SeniorLife and Beth Israel Deaconess Medical Center, could help clinicians more rapidly detect dementia in elderly patients. The Sweet 16 will be available without charge to any nonprofit organization, and may...

Once, scientists and doctors thought we were born with a certain number of neurons and those had to last us throughout our lifespan. Today, neurologists know that new neurons can be produced in adulthood. These adult hippocampal newborn neurons arise in the hippocampus, an area of the brain responsible for learning and memory. Understanding how these neurons live and die could answer questions about diseases that affect learning and memory said Dr. Amanda Sierra Saavedra, a postdoctoral...

Scientist also successfully visualises, in a living cell culture, how the immune cells colonise the brain Findings could lead to new strategies to treat various brain disorders 1. A team of international scientists led by Dr Florent Ginhoux of the Singapore Immunology Network (SIgN) of Singapore's Agency of Science, Technology and Research (A*STAR), have made a breakthrough that could lead to a better understanding of many neurodegenerative and inflammatory brain disorders. Their work,...

By Emil Venere, Purdue University A study by researchers at Purdue University suggests that some high school football players suffer undiagnosed changes in brain function and continue playing even though they are impaired. "Our key finding is a previously undiscovered category of cognitive impairment," said Thomas Talavage, an expert in functional neuroimaging who is an associate professor of biomedical engineering and electrical and computer engineering and co-director of the Purdue MRI...

Unlocking the mystery of neurological disorders starts with understanding how neurons are generated and maintained. Recently, researchers at the Jan and Dan Duncan Neurological Research Institute at Texas Children's Hospital (http://www.nri.texaschildrens.org/) and Baylor College of Medicine (www.bcm.edu) discovered that the life cycle of adult hippocampal newborn neurons was not what was previously thought. Their studies opened new doorways for future research on the process by which neurons...

Using advanced MRI and an artificial intelligence technique, researchers in Geneva, Switzerland, have identified a method that may help identify which individuals with mild cognitive impairment (MCI) will continue to decline, according to a study published online and in the December issue of Radiology. "We know that about half of all individuals with early-stage mild cognitive impairment will progress to Alzheimer's disease," said lead researcher Sven Haller, M.D, M.Sc., a radiologist at...

A new study shows that mild cognitive impairment (MCI) may affect more men than women. The research is published in the September 7, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology. Mild cognitive impairment is a condition in which people have problems with memory or thinking beyond that explained by the normal rate of aging. The study found that MCI was 1.5 times higher in men compared to women. MCI often leads to Alzheimer's...
