Adolescent binge drinking can damage spatial working memory – Binge or “heavy episodic” drinking is prevalent during adolescence, raising concerns about alcohol’s effects on crucial neuromaturational processes during this developmental period. Heavy alcohol use has been associated with decrements in cognitive functioning in both adult and adolescent populations, particularly on tasks of spatial working memory (SWM).
Blast-related injuries detected in the brains of US military personnel – An advanced imaging technique has revealed that some U.S. military personnel with mild blast-related traumatic brain injuries have abnormalities in the brain that have not been seen with other types of imaging. The abnormalities were found in the brain’s white matter, the wiring system that nerve cells in the brain use to communicate with each other.
Study: Memory problems often not present in middle-aged people with Alzheimer’s disease – A new study suggests more than half of people who develop Alzheimer’s disease before the age of 60 are initially misdiagnosed as having other kinds of brain disease when they do not have memory problems.
Work Underway on Potential Alzheimer’s Diagnostic Test Using Spinal Fluid – Researchers at the University of Kentucky are working on a potential diagnostic test for Alzheimer’s disease, based on biomarkers in cerebrospinal fluid.
Spring-cleaning the mind? — Concordia study shows a cluttered brain doesn’t remember – Lapses in memory occur more frequently with age, yet the reasons for this increasing forgetfulness have not always been clear. According to new research from Concordia University, older individuals have reduced learning and memory because their minds tend to be cluttered with irrelevant information when performing tasks.
Musical activity may improve cognitive aging – A study conducted by Brenda Hanna-Pladdy, PhD, a clinical neuropsychologist in Emory’s Department of Neurology, and cognitive psychologist Alicia MacKay, PhD, found that older individuals who spent a significant amount of time throughout life playing a musical instrument perform better on some cognitive tests than individuals who did not play an instrument.
Prenatal exposure to common insecticide linked to decreases in cognitive functioning at age 7 — Deficits in IQ and working memory suggest longer-term educational implications – Researchers from the Columbia Center for Children’s Environmental Health at the Mailman School of Public Health report evidence of a link between prenatal exposure to the insecticide chlorpyrifos and deficits in IQ and working memory at age seven.
Weight loss improves memory, according to Kent State researcher – John Gunstad, an associate professor in Kent State University’s Department of Psychology, and a team of researchers have discovered a link between weight loss and improved memory and concentration. The study shows that bariatric surgery patients exhibited improved memory function 12 weeks after their operations.
Differences in brain structure indicate risk for developing Alzheimer’s disease — Thinning of key cortical areas predicts dementia up to a decade in advance – Subtle differences in brain anatomy among older individuals with normal cognitive skills may be able to predict both the risk of developing Alzheimer’s disease in the following decade and how quickly symptoms of dementia would develop.
As we sleep, speedy brain waves boost our ability to learn — A UC Berkeley study suggests we’re busy recharging our brain?s learning capacity during a dreamless light slumber that takes up half our sleeping hours – During sleep, we’re busy recharging our brain’s learning capacity, which can take up half the night, revealed a new study from the University of California, Berkeley.
Mid-life cholesterol levels not linked to Alzheimer’s disease – Contrary to earlier research, a new, long-term study suggests that cholesterol level in mid-life may not be linked to later development of Alzheimer’s disease.
Rheumatoid arthritis signaling protein reverses Alzheimer’s disease in mouse modeln — New study shows GM-CSF reduces AD pathology and eliminates memory loss – A signaling protein released during rheumatoid arthritis dramatically reduced Alzheimer’s disease pathology and reversed the memory impairment of mice bred to develop symptoms of the neurodegenerative disease, a new study by the University of South Florida reports.
