A new RAND Corporation study found that older women who live in lower socioeconomic status neighborhoods exhibit lower cognitive functioning compared to those in more affluent areas. The study analyzed data from over 6,000 women and found that neighborhood socioeconomic status was significantly associated with cognitive function.
Two studies found that engaging in regular physical activity is linked to less decline in cognitive function in older adults. The studies used objective measures of energy expenditure to analyze data and found a significant association between physical activity and lower rates of cognitive impairment.
A study found that middle-aged adults who slept more or less than 6-8 hours per night experienced accelerated cognitive decline equivalent to four to seven years of aging. This association was seen in both men and women, with no beneficial effects observed for increased sleep duration.

They plan to develop a prototype game based on their findings to improve memory and thinking skills in the elderly.
The study found that US seniors performed significantly better than their English counterparts in cognitive function, with a decade of ageing equivalent between the two groups. Lower levels of depressive symptoms and higher prevalence of hypertension among US adults may have contributed to this advantage.
A study of 2,500 elderly individuals found that those with moderate exercise habits, high education levels, and social engagement were more likely to retain their cognitive skills. These factors, which can be changed through lifestyle modifications, may help prevent or slow the onset of dementia.
Patients who received three infusions of TYSABRI reported significant improvements in general and disease-specific measurements of quality of life (QoL) and cognitive function. Cognitive functioning was assessed by Medical Outcomes Study Cognitive Functioning Scale, with higher scores indicating improved cognition.

A recent study published in Neurobiology of Aging found that being physically fit significantly improves blood flow to the brain, leading to enhanced cognitive abilities. The research, conducted by Marc Poulin and his team, involved comparing two groups of women aged 65, one who was active and the other who was inactive.
A home-based physical activity program improved cognitive function in adults with memory problems, compared to those who did not participate. The study found that exercise delayed recall and reduced Clinical Dementia Rating scores in participants.
Researchers at Tel Aviv University found that Ritalin, used for Attention Deficit Disorder, can improve seniors' cognitive abilities and gait, cutting the risk of serious falls. The study suggests using Ritalin to reduce fall risk in older adults by targeting cognitive deficits.
A randomized trial of simvastatin on cognitive function in children with NF1 found no significant improvement, but a potential benefit in object assembly scores. The study suggests that statins may not be effective in ameliorating cognitive deficits associated with the genetic disorder.
A study of 506 healthy older adults found that subtle neurological abnormalities are associated with increased disability, depression, and cognitive decline. Those with three or more such abnormalities were more likely to die or experience a stroke over eight years.
A new study by Johns Hopkins researchers suggests that heart bypass surgery is not the cause of lasting cognitive problems in patients. After six years of testing, both groups experienced similar declines in cognitive function, indicating that the disease itself may be the culprit.
A randomized clinical trial found that anti-inflammatory drugs celecoxib and naproxen had no effect on cognitive function in older adults with a family history of Alzheimer's disease. In fact, naproxen may have a slightly detrimental effect, according to the study published in Archives of Neurology.
A new neuroimaging study maps functional brain areas to improve cognitive skills before, during, and after brain tumour surgery. The study uses fMRI to localize important areas and preserve motor, sensory, and cognitive abilities.
Studies found that people living in deprived areas had significantly worse cognitive function and higher mobility problems compared to those in less deprived areas. The research highlights the importance of adequate healthcare and social care in poorer communities.
A new study from Harvard University reveals that brain systems in older adults are less coordinated than those in younger individuals, even if there is no Alzheimer's disease present. This decline affects the way different brain regions communicate and process information.
New research suggests that nicotine patches can improve attention and working memory in recovering alcoholics, particularly those who smoke. The study found that these individuals are more sensitive to the effects of nicotine, which may help explain their struggles with quitting nicotine use.
Researchers identified a brain network in the frontal lobe associated with cognitive reserve, which builds through mentally-stimulating activities and provides protection against Alzheimer's disease. The study found that participants with higher levels of cognitive reserve could activate this network while working on difficult tasks.
A six-month study found that a medication initially used for mild to moderate Alzheimer’s disease improved memory and global function in people with severe Alzheimer’s disease. Cognitive tests showed stabilization or improvement in 63% of participants taking the drug compared to 39% on placebo.
Researchers at the University of Pennsylvania found that mindfulness training enhanced performance and attention in subjects. Even new meditators saw improvements in just weeks, with benefits extending to executive functioning skills.
Researchers at Duke University Medical Center found that patients with specific gene variants were less likely to experience cognitive decline after heart surgery. These variants were involved in the inflammatory system and may provide a biological basis for the protective effect observed.
A study found that lactulose improved cognitive function and health-related quality-of-life in patients with minimal hepatic encephalopathy, a condition associated with advanced liver disease. The treatment showed significant improvement in emotional behavior, movement, mobility, sleep/rest, and recreational activities.

A new study published in Kidney International found that Fosrenol, a phosphate binder used to treat hyperphosphatemia in CKD Stage 5 patients, did not negatively impact cognitive function deterioration. The two-year trial compared Fosrenol with standard therapy and showed similar declines in cognitive function for both groups.
Researchers at Johns Hopkins Medicine have identified a critical protein player in cell communication, which controls calcium flow into cells. This finding sheds new light on the rare cognitive disorder Williams-Beuren syndrome, associated with overly social behavior and spatial learning defects.
