Cognition is a concept used in different ways by different disciplines, but is generally accepted to mean the process of thought. For example, in psychology and cognitive science it refers to an information processing view of an individual's psychological functions.

Anxiety helps memory recall, but stress hinders complex problem solving

Researchers at Ohio State University gave a battery of simple cognitive tests to 19 first-year medical students one to two days before a regular classroom exam – a period when they would be highly stressed. Students were also given a similar battery of tests a week after the exam, when things were less hectic.

Researchers have identified a protein in the brain that halts the progression of Alzheimer's

Researchers have identified a protein in the brain that halts the progression of Alzheimer's disease in human brain tissue. The protein, known as "transthyretin," protects brain cells from gradual deterioration by blocking another toxic protein that contributes to the disease process.

New oral vaccine treatment is effective in reducing Alzheimer's disease pathology

Alzheimer's disease is characterized by progressive loss of cognitive function due to amyloid-beta (Aß) deposits in the central nervous system. If these deposits could be stopped or slowed, Alzheimer's disease might become more manageable.

Men undergoing prostate cancer therapy forget things faster

Oregon Health & Science University researchers studying how testosterone deprivation affects verbal memory found that men undergoing the prostate cancer therapy forget things faster than their healthy counterparts.

Strong relationship between kids academic achievement and fitness

The health benefits of exercise – across the lifespan – have been well documented. More recently, scientists have begun to demonstrate that exercise also may improve cognitive functioning in older adults.

Researchers investigate whether hormone therapy and two alternative herbal products can lessen memory in menopausal women

Researchers at the University of Illinois at Chicago are investigating whether hormone therapy and two alternative herbal products can lessen memory and other cognitive problems experienced by menopausal women.

Researchers pinpoint genetic cause of Timothy syndrome

Howard Hughes Medical Institute researchers have pinpointed the genetic cause of a devastating but rare childhood disorder, called Timothy syndrome, which underlies a form of severe cardiac arrhythmia.

Scientists embark on a five-year study of the effects of soy isoflavones found in dietary supplements on various body tissues

A multidisciplinary team of scientists at the University of Illinois at Urbana-Champaign is embarking on a comprehensive five-year study of the effects of soy isoflavones found in dietary supplements on various body tissues.

New tool that cools the body from the inside out, rather than from the outside in

When people exercise, their muscles consume energy and generate heat as a byproduct. When enough heat accumulates internally, it can limit exercise performance.

Women aged 70 years and older who exercised regularly lower risk of cognitive impairment

Women who engaged in the most activity - for example, walking at least 6 hours per week - had a 20 percent decrease in risk of cognitive impairment compared to those who were inactive and, also demonstrated the cognitive functioning of someone three-years younger than their actual age.

New gene therapy technique may help treat Alzheimer's disease

Investigators at Rush University Medical Center have successfully initiated a new technique that uses gene therapy to deliver nerve growth factor into regions of the brain where neurons are degenerating, in order to prevent cell death and reverse cell atrophy, two hallmarks of Alzheimer's disease.

Walking helps elderly men stave off dementia and Alzheimer's disease

Elderly men who are sedentary or walk less than a quarter of a mile per day are nearly twice as likely to develop dementia and Alzheimer's disease compared to men who walk more than two miles per day, according to a study of over 2,200 Japanese-American men in Hawaii.

Immunoglobulins might be promising treatment for Alzheimer's disease

Intravenous immunoglobulin might offer a promising treatment for Alzheimer's disease, suggests preliminary research in the Journal of Neurology Neurosurgery and Psychiatry.

Higher blood levels of homocysteine may be associated with changes in deep brain tissue in middle-aged men

According to the article, high HCY levels have been associated with an increased risk for vascular diseases, and some studies have suggested that HCY may also increase the risk for brain atrophy and Alzheimer disease. Other studies have shown an inverse relationship between elevated HCY levels and cognitive functioning, the article states.

Transthyretin discovery may halt progression of Alzheimer's

In a finding that may cause a dramatic shift in the way scientists and researchers search for a therapy for Alzheimer's disease, a team of researchers led by Jeff Johnson, an associate professor at the School of Pharmacy, has discovered that increased expression of a protein called transthyretin in the brain appears to halt the progression of the disease.
