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.

Abuse, self-neglect places seniors at increased risk for premature death

Older adults who are subjected to abuse or self-neglect face a greater risk of premature death than other seniors, according to a study published in the medical journal JAMA.

High-fat diets just as unhealthy in short term as long term

Short-term memory getting worse? Exercise getting harder? Examine your diet. New research published online in The FASEB Journal showed that in less than 10 days of eating a high-fat diet, rats had a decreased ability to exercise and experienced significant short-term memory loss. These results show an important link between what we eat, how we think, and how our bodies perform.

Children with newly diagnosed epilepsy at risk for cognitive problems

Children who have normal IQs before they experience a first seizure may also have problems with language, memory, learning and other cognitive skills, according to a study published in the August 12, 2009, online issue of Neurology, the medical journal of the American Academy of Neurology.

Education impacts cognitive function in Alzheimer's disease

Researchers at the Department of Psychiatry, Klinikum rechts der Isar, Technische Universität München, investigated the effects of formal education on the symptoms of Alzheimer's disease. They were able to show that education diminishes the impact of Alzheimer's disease on cognition even if a manifest brain volume loss has already occurred.

High-fat diet affects physical and memory abilities of rats after 9 days

Rats fed a high-fat diet show a stark reduction in their physical endurance and a decline in their cognitive ability after just nine days, a study by Oxford University researchers has shown.

Botanicals do not have an effect on hot flashes or on cognitive function in menopausal women

Two studies conducted by researchers at the University of Illinois at Chicago and Northwestern University have found that commonly used botanicals do not have an effect on hot flashes or on cognitive function in menopausal women.

Clinical trial to test gene therapy for Alzheimer’s disease

Researchers at the Shiley-Marcos Alzheimer's Disease Research Center at the University of California San Diego are about to launch a Phase 2 clinical trial to test a gene therapy treatment for Alzheimer’s disease (AD) called CERE-110.

Genetic risk, not anesthesia exposure, impacts cognitive performance

A recent study of more than 2,000 identical twins found that medical problems early in life, rather than the neurotoxic effects of anesthesia, are likely linked to an individual's risk for developing learning disabilities.

High levels of glutamate in brain linked to depression, low cognitive function

Researchers at the Joslin Diabetes Center and several other institutions have for the first time linked high levels of glutamate – a neurotransmitter in the brain produced from glucose – in people with type 1 diabetes to symptoms of depression and lower levels of cognitive performance. The findings may lead to a better understanding of the underlying mechanisms of these conditions in people with diabetes.

Long-term brain damage after bypass surgery - more evidence puts blame on heart disease

Brain scientists and cardiac surgeons at Johns Hopkins have evidence from 227 heart bypass surgery patients that long-term memory losses and cognitive problems they experience are due to the underlying coronary artery disease itself and not ill after-effects from having used a heart-lung machine.

Acute stress improves working memory

Day after day of chronic stress will wear a person down physically and mentally. But new research suggests that the acute stress produced by a brief run-in with a stressful scenario acts on a key brain region controlling emotion and cognition, temporarily improving learning and memory.

Effect of sunlight exposure on cognitive function among depressed and non-depressed participants

A lack of sunlight is associated with reduced cognitive function among depressed people. Researchers writing in BioMed Central's open access journal Environmental Health used weather data from NASA satellites to measure sunlight exposure across the United States and linked this information to the prevalence of cognitive impairment in depressed people.

Enzyme implicated in blood flow in Alzheimer’s, disease progression

Researchers have discovered that the enzyme, endothelin converting enzyme-2 (ECE-2), may cause the decrease in blood flow in the brain seen in Alzheimer's disease and contribute to progression of the disease.

Improving patients' attention after a stroke could help them recover their motor skills

Scientists in New Zealand say after a stroke improving patients' attention could help them to recover their motor skills.

Some blood pressure drugs may help protect against dementia, study shows

A particular class of medication used to treat high blood pressure could protect older adults against memory decline and other impairments in cognitive function, according to a newly published study from Wake Forest University School of Medicine.

Short stressful events may improve working memory

Experiencing chronic stress day after day can produce wear and tear on the body physically and mentally, and can have a detrimental effect on learning and emotion. However, acute stress -- a short stressful incident -- may enhance learning and memory.

Close caregiver relationship may slow Alzheimer's decline

A study led by Johns Hopkins and Utah State University researchers suggests that a particularly close relationship with caregivers may give people with Alzheimer's disease a marked edge over those without one in retaining mind and brain function over time. The beneficial effect of emotional intimacy that the researchers saw among participants was on par with some drugs used to treat the disease.

Diet rich in fish helps prevent dementia

According to experts over 24 million people worldwide are thought to suffer from dementia, and many of these people live in low and middle-income countries.

Preliminary findings in Phase IIA trial point to natural compound NIC5-15's potential in Alzheimer's disease

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.

Research finds earliest evidence of memory decline in middle-aged people at genetic risk for Alzheimer's

Memory lapses that occur with normal aging are a source of worry for many who fear Alzheimer's disease. Now a new Mayo Clinic-led study published in the July 16 issue of the New England Journal of Medicine suggests that the carriers of a common genetic risk factor for Alzheimer's disease begin to have memory declines in their mid-50s, far earlier than previously thought.
