Losing sleep undoes the rejuvenating effects new learning has on the brain
Sleep deprivation impairs spatial learning - including remembering how to get to a new destination. And now scientists are beginning to understand how that happens view more (2006-01-09)
Personality predictors of intelligence change from younger to older adulthood
An ability to be open to new situations may predict intelligence earlier in life, says a new study, but disagreeableness may predict intelligence later in life. view more (2006-08-11)
Study shows link between morbid obesity, low IQ in toddlers
University of Florida researchers have discovered a link between morbid obesity in toddlers and lower IQ scores, cognitive delays and brain lesions similar to those seen in Alzheimer's disease patients, a new study shows. view more (2006-09-01)
Alzheimer's disease progresses more rapidly in highly educated people
High levels of education may help ward off Alzheimer's disease, but they also speed up its progression once developed, reveals research in the Journal of Neurology Neurosurgery and Psychiatry. view more (2006-02-16)
Boosting brain power — with chocolate
Eating chocolate could help to sharpen up the mind and give a short-term boost to cognitive skills, a University of Nottingham expert has found. view more (2007-02-21)
Daytime light exposure dynamically enhances brain responses
Exposure to light is known to enhance both alertness and performance in humans, but little is understood regarding the neurological basis for these effects, especially those associated with daytime light exposure. view more (2006-08-22)
Memory loss in older adults due to distractions, not inability to focus
The short-term memory problems that accompany normal aging are associated with an inability to filter out surrounding distractions, not problems with focusing attention, according to a study by researchers at the University of California, Berkeley. view more (2005-09-12)
Chronic drinking and smoking cause both separate and interactive brain injury
Most alcoholics in North America are chronic smokers. While much is known about the adverse effects of chronic smoking on cardiac, pulmonary and vascular function as well as the risk for various cancers, little is known about its effects on brain neurobiology and function. view more (2006-01-25)
TV has negative impact on very young children's learning abilities
Television viewing before the age of three may have adverse effects on subsequent cognitive development, according to a study in the July issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals. view more (2005-07-05)
Researchers isolate causes of cognitive loss following coronary artery bypass surgery
Minimizing trauma to the body's largest artery - the aorta - during heart bypass surgery can significantly reduce cognitive loss that often follows the operation. view more (2006-01-23)
Brain function in schizophrenia can improve with support, holds promise for cognitive rehabilitation
When encouraged to use memorization strategies commonly employed by healthy individuals, people with schizophrenia can be helped to remember information just as well as their healthy counterparts, a process that in itself seems to spur a normalization of memory-related activities in the brains of people with schizophrenia. view more (2005-07-06)
Alzheimer's pathology related to episodic memory in those without dementia
Alzheimer's pathology can appear in the brains of older men and women without dementia or mild cognitive impairment. view more (2006-06-27)
Study shows fruit and vegetable juice consumption may reduce risk of Alzheimer's disease
Drinking fruit and vegetable juices frequently may delay the onset of Alzheimer's disease. view more (2006-09-01)
Drug triggers body's mechanism to reverse aging effect on memory process
A drug made to enhance memory appears to trigger a natural mechanism in the brain that fully reverses age-related memory loss, even after the drug itself has left the body, according to researchers at UC Irvine. view more (2006-07-28)
Human brains pay a price for being big
Metabolic changes responsible for the evolution of our unique cognitive abilities indicate that the brain may have been pushed to the limit of its capabilities. Research published today in BioMed Central's open access journal Genome Biology adds weight to the theory that schizophrenia is a costly by-product of human brain evolution. view more (2008-08-05)
Patients regain cognitive function after radiation for brain tumors
Patients who suffer from low-grade brain tumors are able to regain normal cognitive function after receiving radiation therapy to shrink their tumor. view more (2005-11-16)
REM sleep behaviour disorder is an early marker of neurodegenerative diseases
The front page of the July 2006 issue of The Lancet Neurology, the journal with the highest international impact, contains a work that shows the relationship between disorders during REM sleep and future neurodegenerative pathologies. view more (2006-06-29)
Nicotine exposure during development leads to hearing problems
Scientists know that children of women who smoke during pregnancy can develop hearing-related cognitive deficits. For the first time, researchers believe they have evidence that not only implicates nicotine as the culprit, but also shows what the substance does to the brain to cause these deficits. view more (2006-07-19)
Smoking seems to increase brain damage in alcoholics
It is already well-known that the brains of long-term alcoholics atrophy and shrink, the study authors say, but the new findings are the first evidence that cigarette smoking might contribute to that atrophy, particularly in grey matter of the parietal and temporal lobes. view more (2005-09-29)
'Word-vision' brain area confirmed
Humans have an uncanny ability to skim through text, instantly recognizing words by their shape-even though writing developed only about 6000 years ago-long after humans evolved. view more (2006-04-20)
