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.

Blood test for early detection of Alzheimer’s disease

Soon researchers may be able to detect signs of Alzheimer's disease before symptoms appear by a simple blood test. Currently, biological tests to diagnose Alzheimer's use invasive and costly procedures including brain imaging and spinal punctures.

Starvation during childhood may increase risk of heart complications

Russians born during the Leningrad Siege in World War II, which was responsible for some of the greatest losses of civilian life in history, are giving scientists new strategies to identify people who experienced intrauterine growth restriction (IUGR) and starvation during childhood at greatest risk of developing long term heart complications.

Scientists produce first genetic brain atlas

The first atlas of the surface of the human brain based upon genetic information has been produced by a national team of scientists, led by researchers at the University of California, San Diego School of Medicine and the VA San Diego Healthcare System.

Dementia numbers to triple by 2050: Australian Report

In a discussion paper given to the State Government, Alzheimer's Australia NSW estimates the number of Australians diagnosed with dementia will rise from 280,000 to around 943,000 by 2050. Of these, 303,500 people will be from NSW.

Dementia research gets a boost in the UK

The UK has seen a rise in the number of dementia sufferers by 50,000 in the past year, new figures have revealed. There are now more than 800,000 victims in Britain, with three out of four becoming anxious or depressed and six out of 10 feeling lonely, according to a new survey.

International Alzheimer's experts unite for global effort

The world’s leading Alzheimer’s disease researchers and clinicians will gather in Melbourne this week to agree on standardisation and validation of important diagnostic and prognostic parameters used in Alzheimer’s research centres around the globe.

Obesity in later life linked to decreased mental faculties

The study found said out of 250 test subjects involving people over 59 years old, people between 60 and 70 who had the highest BMIs also had the lowest cognitive function. There was also a connection between visceral fat -- otherwise known as the belly fat around the torso - and poor mental abilities. The study, which was published in the British journal Age and Aging, measured the subjects fat-related measures including BMI, waist circumference and the amount of visceral - which could be close to organs - and subcutaneous -under the skin - fat using a abdominal CT scan. Cognitive ability was determined by a test called a Mini-Mental State Examination.

Mendelian randomization not the 'Holy Grail' in evaluating alcohol intake with cognitive function

Many observational cohort studies have shown that moderate alcohol use is associated with better cognitive function. However, since such studies are vulnerable to residual confounding by other lifestyle and physiologic factors, the authors conducted a Mendelian randomization study, using aldehyde dehydrogenase 2 (ALDH2) genotype (AA, GA, or GG) as an instrumental variable in 2-stage least squares analysis.

Hospitalized older adults may have increased risk of cognitive decline

A new study published in the March 21 issue of Neurology suggests that older adults who are hospitalized may have an increased risk of subsequent cognitive decline.

Two new studies strongly support link between insulin resistance and Alzheimer's

An emerging body of research suggests that Alzheimer's disease may be linked to insulin resistance, constituting a third type of diabetes. This model is based on several observations including an increased risk of developing Alzheimer's disease for diabetic patients, and reduced insulin levels in the brain tissue of Alzheimer's disease patients. Though intriguing, the existing evidence does not reveal if defective insulin signaling is causative of Alzheimer's or how insulin resistance impacts cognitive function.

Disruptions in immune system regulation may play a role in NEC

Despite advances in neonatal care, necrotizing enterocolitis (NEC) - the most common gastrointestinal emergency in premature infants - continues to be a deadly disease. "We haven't made a lot of progress in identifying babies early who may be at risk for NEC, preventing it or treating it," said J-rn-Hendrik Weitkamp, M.D., a neonatologist and assistant professor of Pediatrics at Monroe Carell Jr. Children's Hospital at Vanderbilt.

Low literacy equals high death risk among elderly

A new study that appeared last Friday in British Medical Journal showed that one in three adults aged over 65 in England have difficulty understanding basic health-related information. They are more than twice as likely to die within five years as adults with no literacy problems, it was found.

Mobile phone exposure in unborn mice raises risk of behavioral and memory disorders

A new study has shown that unborn mice exposed to mobile phone radiation became hyperactive adults with poor memory. But scientists have added that the findings cannot be translated to humans.

Warm weather may hinder cognitive performance in people with multiple sclerosis

Warm weather may hinder cognitive performance in people with multiple sclerosis (MS), according to results of a Kessler Foundation study e-published online ahead of print by Neurology. An accompanying editorial by Meier & Christodoulou, MS and heat: The smoke and the fire, details the study's unique aspects, ie, longitudinal followup in a cohort with apparently quiescent disease.

Rats’ decision making as good as humans: Study

It is a known fact that rats are smart. But now US researchers have shown that they may be just as good as humans at juggling information in order to make the best decision. The discovery could help scientists better understand how the brain works in order to help people with autism who have difficulty processing various stimuli the way that others can, said the study authors.

Patients with advanced Alzheimer’s benefit from drugs: Study finds

According to new developments patients with advanced Alzheimer’s disease could benefit from drug treatment to slow its progression. Scientists have shown for the first time that drugs used to slow the disease in its early stages also work when the condition is advanced, greatly extending the population who could be treated.

Surgical intervention can be life-restoring for people with intractable temporal lobe epilepsy

While the thought of any type of surgery can be disconcerting, the thought of brain surgery can be downright frightening. But for people with a particular form of epilepsy, surgical intervention can literally be life-restoring.

AMTR soon after failure of AEDs may reduce risk of seizures in epilepsy patients

Patients with epilepsy who underwent brain surgery soon after failing to respond to drug treatment, but who also continued to receive drug therapy, had a lower risk of seizures during the 2nd year of follow-up compared to patients who received drug treatment alone, according to a study in the March 7 issue of JAMA.
