Taking care of grandkids one day a week helps keep grandmothers mentally sharp, shows study

Taking care of grandkids one day a week helps keep grandmothers mentally sharp, finds a study from the Women's Healthy Aging Project study in Australia, published online today in Menopause, the journal of The North American Menopause Society (NAMS). [More]

African Americans are at higher risk of developing Alzheimer's disease than white population

A new study by researchers at Rush University Medical Center reviews research that suggests that the risk for developing Alzheimer's disease among older African Americans may be two to three times greater than in the non-Hispanic white population and that they differ from the non-Hispanic white population in risk factors and disease manifestation.

Ketamine offers novel treatment for patients with severe depression

Ketamine offers novel treatment for patients with severe depression

New data show ketamine (a drug widely used for anaesthesia and pain relief) has a rapid antidepressant effect in some patients with severe depression. The first UK study of ketamine intravenous infusions in people with treatment-resistant depression was conducted by the Oxford Health NHS Foundation Trust and the University of Oxford. [More]

Sleep fragmentation, poor sleep quality associated with decline in executive function

A new study of older men found a link between poor sleep quality and the development of cognitive decline over three to four years. [More]
Young adults with cardiac risk factors have worse cognitive function in middle age

Young adults with cardiac risk factors have worse cognitive function in middle age

Young adults with such cardiac risk factors as high blood pressure and elevated glucose levels have significantly worse cognitive function in middle age, according to a new study by dementia researchers at UC San Francisco. [More]

Two new risk loci for bipolar disorder identified

Researchers have found two new risk loci for bipolar disorder in a genome-wide association study of 2.3 million single-nucleotide polymorphisms. [More]
Eye abnormalities may help reveal features of early-stage Alzheimer's disease, says study

Eye abnormalities may help reveal features of early-stage Alzheimer's disease, says study

‚ÄčInvestigators at the Cedars-Sinai Regenerative Medicine Institute have discovered eye abnormalities that may help reveal features of early-stage Alzheimer's disease. Using a novel laboratory rat model of Alzheimer's disease and high-resolution imaging techniques, researchers correlated variations of the eye structure, to identify initial indicators of the disease.

Kessler Foundation receives grant to supports variety of rehabilitation research projects in spinal cord injury

Kessler Foundation receives grant to supports variety of rehabilitation research projects in spinal cord injury

Kessler Foundation has received more than $718,000 in grant funding from the Craig Neilsen Foundation. The funding, comprised of five grants, supports a variety of rehabilitation research projects in spinal cord injury (SCI), including pain management, functional outcomes, quality of life, and factors affecting cognitive function.

Researchers create statistical model to predict whether heart scans are useful in prescribing statins

Researchers create statistical model to predict whether heart scans are useful in prescribing statins

As long as inexpensive statins, which lower cholesterol, are readily available and patients don't mind taking them, it doesn't make sense to do a heart scan to measure how much plaque has built up in a patient's coronary arteries before prescribing the pills, according to a new study by researchers at UC San Francisco.

Education improves cognitive performance decades after school completion

Education improves cognitive performance decades after school completion

European populations are growing older on average, a trend that could pose serious challenges to health care, budgets, and economic growth. As a greater proportion of a country's population grows into old age, average cognition levels and national productivity tend to decline, and the incidence of dementia increases. [More]

Plaque in brain could guide treatment decisions for patients at risk for Alzheimer's

Brain imaging using radioactive dye can detect early evidence of Alzheimer's disease that may predict future cognitive decline among adults with mild or no cognitive impairment, according to a 36-month follow-up study led by Duke Medicine. [More]

Decision-making accuracy can be improved by postponing onset of decision

Columbia University Medical Center (CUMC) researchers have found that decision-making accuracy can be improved by postponing the onset of a decision by a mere fraction of a second. [More]
BWH researchers explore newer approaches to treat Alzheimer's disease

BWH researchers explore newer approaches to treat Alzheimer's disease

A team of Alzheimer's disease (AD) researchers at Brigham and Women's Hospital (BWH) has been able to study the underlying causes of AD and develop assays to test newer approaches to treatment by using stem cells derived from related family members with a genetic predisposition to (AD). [More]
New study uses Lumosity games to detect subtle cognitive impairments in patients with cirrhosis

New study uses Lumosity games to detect subtle cognitive impairments in patients with cirrhosis

A new study from the University of Washington has found that performance on Lumosity games can distinguish between patients with cirrhosis of the liver, pre-cirrhotic patients, and healthy controls. The study used Lumosity games as psychometric tests to detect subtle cognitive impairments in patients with cirrhosis. The study is published in the March issue of the American Journal of Gastroenterology. [More]
Study links carbohydrate calorie-rich diets to greater risk for brain shrinkage, dementia and AD

Study links carbohydrate calorie-rich diets to greater risk for brain shrinkage, dementia and AD

‚ÄčEven small increases in blood sugar caused by a diet high in carbohydrates can be detrimental to brain health. Recent reports in medical literature link carbohydrate calorie-rich diets to a greater risk for brain shrinkage, dementia and Alzheimer's disease, impaired cognition, and other disorders. [More]

Resolution of inflammation is altered in Alzheimer's disease

New research from Karolinska Institutet in Sweden shows that the final stage of the normal inflammatory process may be disrupted in patients with Alzheimer's disease. [More]

Final stage of normal inflammatory process may be disrupted in patients with Alzheimer's disease

New research from Karolinska Institutet in Sweden shows that the final stage of the normal inflammatory process may be disrupted in patients with Alzheimer's disease. A study published in the journal Alzheimer's & Dementia shows that levels in the brain and cerebrospinal fluid of the molecules necessary for tissue recovery through the clearance of harmful inflammatory substances are lower than normal in patients with Alzheimer's disease. The study also showed association between the lower levels of these molecules with impaired memory function. [More]

Exposure to common infections linked to memory and brain function

Exposure to common infections is linked to memory and brain function - even if the infections never made you ill, according to research presented at the American Stroke Association's International Stroke Conference 2014. [More]
