Cognitive Function News and Research RSS Feed - Cognitive Function News and Research

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.

Two simple measures can help decrease incidence of POCD in older patients

Two simple measures can help decrease incidence of POCD in older patients

Post-operative cognitive dysfunction (POCD), a condition mostly observed in older patients following surgery under general anesthesia, is characterized by impaired memory and concentration. The impairment may be temporary or permanent and incapacitating. [More]
Single, short duration exposure of general anesthesia appears to cause no cognitive harm in healthy, young children

Single, short duration exposure of general anesthesia appears to cause no cognitive harm in healthy, young children

A recent study concluded that very young, healthy children undergoing short surgical procedures requiring a single exposure to general anesthesia did not exhibit any effect on the cognitive outcomes tested, according to SmartTots, a public-private partnership of the International Anesthesia Research Society and the U.S. Food and Drug Administration.

Dirty working environment can impact cognitive function of employees

A new study by a Florida State University researcher shows that both a lack of stimulation in the workplace and a dirty working environment can have a long-term cognitive effect on employees. [More]
Cerebral microbleeds linked to increased risk of physical, cognitive disability in MS patients

Cerebral microbleeds linked to increased risk of physical, cognitive disability in MS patients

Leaky blood vessels in the brain called cerebral microbleeds are associated with an increased risk of physical and cognitive disability in patients with multiple sclerosis (MS), according to a new study by researchers in the Jacobs School of Medicine and Biomedical Sciences at the University at Buffalo.

New technique may help replace brain cells, restore memory

New technique may help replace brain cells, restore memory

Although brains—even adult brains—are far more malleable than we used to think, they are eventually subject to age-related illnesses, like dementia, and loss of cognitive function. [More]
Gist reasoning training can strengthen cognitive domains in individuals with MCI

Gist reasoning training can strengthen cognitive domains in individuals with MCI

New research from the Center for BrainHealth at The University of Texas at Dallas shows that strategy-based reasoning training can improve the cognitive performance for those with mild cognitive impairment (MCI), a preclinical stage of those at risk for Alzheimer's disease. [More]
U-M researchers explore new way to improve cognitive issues in MS patients

U-M researchers explore new way to improve cognitive issues in MS patients

Multiple sclerosis looks different from person to person. In many individuals, though, the difficulty in maintaining a sense of self and in keeping up intellectually can be the disease's most devastating manifestations. [More]
Study provides new insight into poorly understood effects of high explosive blasts in male soldiers

Study provides new insight into poorly understood effects of high explosive blasts in male soldiers

Scientists have identified a distinctive pattern of injury in the brains of eight deceased military personnel who survived high explosive attacks and died between 4 days and 9 years later from their injuries or other causes. [More]
Advanced imaging technique helps predict recovery in concussion patients

Advanced imaging technique helps predict recovery in concussion patients

Using an advanced imaging technique, researchers at Albert Einstein College of Medicine and Montefiore Health System were able to predict which patients who'd recently suffered concussions were likely to fully recover. [More]

Personlized exercise pattern may help reduce neuropathic symptoms of chemotherapy

Researchers at the University of Rochester Wilmot Cancer Institute discovered something simple and inexpensive to reduce neuropathy in hands and feet due to chemotherapy--exercise. [More]
Intellectually challenging job linked to better memory, cognitive functioning

Intellectually challenging job linked to better memory, cognitive functioning

Working in a more intellectually challenging job is associated with better memory and other aspects of cognitive functioning, reports a study in the June Journal of Occupational and Environmental Medicine, official publication of the American College of Occupational and Environmental Medicine.

NMNAT2 enzyme may help protect against debilitating effects of neurodegenerative disorders

NMNAT2 enzyme may help protect against debilitating effects of neurodegenerative disorders

A study led by biomedical researchers at Indiana University has found evidence that an enzyme known as NMNAT2 may help protect against the debilitating effects of certain degenerative brain diseases, including Alzheimer's. [More]
Existing MCI screening tools result in more than 7% false-negative error rate, study finds

Existing MCI screening tools result in more than 7% false-negative error rate, study finds

Mild cognitive impairment (MCI) is a slight but noticeable and measurable decline in cognitive abilities, such as remembering names or a list of items. While changes may not be severe enough to disrupt daily life, a clinical diagnosis of MCI indicates an increased risk of eventually developing Alzheimer's disease or another type of dementia. [More]
Heart failure patients who receive influenza vaccine less likely to develop dementia

Heart failure patients who receive influenza vaccine less likely to develop dementia

Influenza vaccination is associated with a lower risk of dementia in patients with heart failure, according to a study in more than 20 000 patients presented today at Heart Failure 2016 and the 3rd World Congress on Acute Heart Failure by Dr Ju-Chi Liu, director of the Division of Cardiovascular Medicine, Department of Medicine, Taipei Medical University - Shuang Ho Hospital, in New Taipei City, Taiwan.

Nine creative ways to improve cognitive development of children in developing countries

Grand Challenges Canada, funded by the Government of Canada, and the "Saving Brains" partners today announced investments in nine creative ways to protect and nurture the cognitive development of children in developing countries. [More]
New research may increase understanding of link between olfactory decline and brain-related diseases

New research may increase understanding of link between olfactory decline and brain-related diseases

Deterioration in a person's ability to smell can sometimes be an early sign of neurodegenerative diseases such as Parkinson's or Alzheimer's. [More]
Severe obstructive sleep apnea may increase likelihood of cognitive deficits in children

Severe obstructive sleep apnea may increase likelihood of cognitive deficits in children

Sleep assessments in young children showed that, in the context of habitual snoring and enlarged tonsils and adenoids, moderate to severe obstructive sleep apnea increased the likelihood and magnitude of cognitive deficits. [More]
