Hormone therapy linked to brain shrinkage, but not lesions – Two new studies show that hormone therapy for women is linked to brain shrinkage, but not to the small brain lesions that are the first sign of cerebrovascular disease.
Adult-onset diabetes slows mental functioning in several ways, with deficits appearing early – Adults with diabetes experience a slowdown in several types of mental processing, which appears early in the disease and persists into old age, according to new research.
Salk researchers develop novel brain cancer glioblastoma mouse model. – Researchers at the Salk Institute for Biological Studies have developed a versatile mouse model of glioblastoma-the most common and deadly brain cancer in humans-that closely resembles the development and progression of human brain tumors that arise naturally.
Researchers at Columbia University Medical Center link blood sugar to normal cognitive aging – Maintaining blood sugar levels, even in the absence of disease, may be an important strategy for preserving cognitive health, suggests a study published by researchers at Columbia University Medical Center (CUMC).
Marijuana could help reduce memory loss in old age and fight Alzheimer’s Disease and dementia, revealed by researchers. – The more research they do, the more evidence Ohio State University scientists find that specific elements of marijuana can be good for the aging brain by reducing inflammation there and possibly even stimulating the formation of new brain cells.
Ginkgo biloba does not reduce dementia or Alzheimer’s disease risk according to Pitt-led study in JAMA. – The medicinal herb Ginkgo biloba does not reduce the risk of dementia or Alzheimer’s disease development in either the healthy elderly or those with mild cognitive impairment, according to a large multicenter trial led by researchers at the University of Pittsburgh School of Medicine.
‘Super’ aged brains reveal first secrets of sharp memory in old age. Super aged brains had many fewer fiber-like tangles than the brains of those who had aged normally. – Researchers at Northwestern University’s Feinberg School of Medicine wondered if the brains of the elderly with still laser sharp memory — called “super aged” — were somehow different than everyone else’s.
Brain imaging study supports the ‘cognitive reserve’ hypothesis. Greater education has been associated with better cognitive function during life. – Individuals with higher education levels appear to score higher on cognitive tests despite having evidence of brain plaques associated with Alzheimer’s disease.
Gladstone scientists identify role of fatty acids in Alzheimer’s disease, large-scale analysis of brain lipids identifies potential therapeutic strategy. – Scientists at the Gladstone Institute of Neurological Disease (GIND) and the University of California have found that complete or partial removal of an enzyme that regulates fatty acid levels improves cognitive deficits in a mouse model of Alzheimer’s disease (AD).
New study determines double flu jab needed against bird flu pandemic. Scientists recommend stockpiling influenza vaccine. – An international study led by University of Leicester researchers has determined that vaccination will be the best way to protect people in the event of the next influenza pandemic ? but that each person would need two doses.
Possible cause of antisocial behavior identified. Reduced stress hormone cortisol cause antisocial behavior – A link between reduced levels of the ‘stress hormone’ cortisol and antisocial behaviour in male adolescents has been discovered by a research team at the University of Cambridge.
Erasing drug-associated memories to treat drug addiction is a new approach that has great potential. – Erasing drug-associated memories may prevent recovering drug abusers from relapsing, researchers at the University of Cambridge have discovered.
