Older adults exposed to high levels of lead before the 1980s are showing signs of cognitive decrements as a result of long-term lead exposure in their communities. view more (2006-09-14)
Researchers use novel three-dimensional imaging technique
Using an innovative three-dimensional imaging technique, a team of UCLA researchers have tracked how Alzheimer's disease spreads through the hippocampus - the area of the brain linked with memory - in a pattern consistent with the known trajectory of neurofibrilliary tangle dissemination, an accumulation of diseased proteins in the brain cells. view more (2006-10-26)
Food shortages threaten Antarctic wildlife
Antarctic whales, seals and penguins could be threatened by food shortages in the Southern Ocean. Numbers of Antarctic krill (Euphausia superba), a shrimp-like crustacean at the heart of the food chain, are declining. The most likely explanation is a dramatic decline in sea-ice. The results are published this week in the journal Nature. view more (2004-11-01)

Mild sadness provokes depressive thinking in some recovered patients
Some individuals with a history of depression may sink back into thinking patterns associated with the condition when faced with mild stresses or sadness, increasing their risk for relapse. view more (2006-07-05)
Passive smoking link to dementia
Researchers from the Peninsula Medical School, the University of Cambridge and the University of Michigan have published the results of the first large-scale study to indicate that second-hand smoke exposure could lead to dementia and other neurological problems. view more (2009-02-13)
Loss of body mass linked to development of Alzheimer's disease
Loss of body mass over time appears to be strongly linked to older adults' risk of developing Alzheimer's disease (AD), and the greater the loss the greater the chance of a person developing the disease, new research has found. view more (2005-09-27)
Study indicates grape seed extract may reduce cognitive decline associated with Alzheimer's disease
A compound found in grape seed extract reduces plaque formation and resulting cognitive impairment in an animal model of Alzheimer's disease, new research shows. The study appears in the June 18 issue of The Journal of Neuroscience. view more (2008-06-18)
Mount Sinai researchers find new Alzheimer's disease treatment promising
Researchers at Mount Sinai School of Medicine have found that a compound called NIC5-15, might be a safe and effective treatment to stabilize cognitive performance in patients with mild to moderate Alzheimer's disease. view more (2009-07-13)
2 nondrug treatments appear to reduce depression after heart surgery

Breakthrough for Kids with Epilepsy: Surgery Reduces Seizures and Increases IQ
A study on 50 preschool-aged children with epilepsy who underwent surgical treatment showed significant improvements on overall cognitive development and left many seizure-free. The article is published in the journal Epilepsia. view more (2005-04-22)
Kids with OSA: Marker for cardiovascular disease may also indicate severity of cognitive disability
C-reactive protein, a marker of inflammation that is often used to detect cardiovascular disease, may also indicate cognitive impairment in children with obstructive sleep apnea (OSA), according to a new study of children ages 5 to 7. view more (2007-07-16)
Increased cognitive control in Tourette's syndrome
Though the repetitive vocal and motor tics characteristic of Tourette's syndrome may suggest an inability to control involuntary actions at the cognitive level, researchers have now found evidence that young people with Tourette's syndrome actually exhibit a greater level of cognitive control over their movements than their non-affected peers do. view more (2006-03-21)
New computer program uses brain scans to assess risk of Alzheimer's
New York University School of Medicine researchers have developed a brain scan-based computer program that quickly and accurately measures metabolic activity in a key region of the brain affected in the early stages of Alzheimer's disease. view more (2005-06-20)
Metacognition: Faced with a test, rats can check their knowledge first
Researchers have found evidence that rats are capable of metacognition—that is, they can possess knowledge of their own cognitive states. view more (2007-03-09)
Efficacy Of The Cognitive Behavioural Group Psychotherapy For HIV-Infected Patients
A group of investigators of the University of Barcelona have reported on the value of a group psychotherapy program in HIV-1 infected patients.

IS THE AMERICAN LEADERSHIP IN CLINICAL MEDICINE RESEARCH DECLINING? A CITATION ANALYSIS
Citation analysis is a powerful measurement of the scientific impact of medical papers. All papers which were published in journals of general and internal medicine (such as the Lancet or the New England Journal of Medicine), the citations which attracted and their impact (citations divided by number of papers) were analyzed according to country... view more...

Single genetic defect produces specific cognitive deficit in mice
Researchers have found that, in mice, producing a single genetic defect in a molecule that "reloads" neurons to trigger one another using the neurotransmitter acetylcholine impairs the mice's ability to recognize objects or other mice. view more (2006-09-07)
