Subtle cognitive decline precedes end to driving for older adults

Even slight cognitive changes can affect an older person’s decision to stop driving, according to a new study by researchers at Washington University School of Medicine in St. Louis. The findings suggest that routine cognitive testing — in particular, the kind of screening designed to pick up the earliest, most subtle decline — could help older adults and their physicians make decisions about driving that maximizes safety while preserving independence as long as possible.

Study Reveals How Obesity Could Accelerate Aging in the Brain

A new study conducted in mice traces how obesity and a high-fat diet may accelerate aging in the blood vessels that supply blood to the brain. The work is being presented this week at the American Physiology Summit, the flagship annual meeting of the American Physiological Society.

‘Curved’ Walking and a Depth Camera: New Tool Detects Early Cognitive Decline

Gait impairments often are prevalent in the early stages of cognitive decline. Researchers quantitatively compared straight walking and curved walking – a more natural yet complex activity – in healthy older adults and adults with mild cognitive impairment (MCI). A depth camera detected and tracked 25 joints of body movement and signals were processed to extract 50 gait markers. Intriguingly, curved walking illuminated notable disparities between the study groups.

Study Detects Cognitive Changes in Older Drivers Using In-vehicle Sensors

Continuous, unobtrusive sensors and related monitoring devices are installed in older drivers’ vehicles to detect changes in highly complex activities over time. A driver facing camera, forward facing camera, and telematics unit provide video in real-time to enable researchers to analyze abnormal driving such as getting lost, reaction time and braking patterns as well as travel patterns such as miles driven, miles during the night and daytime, and driving in severe weather. Detecting changes in behavior could generate early warning signs of possible changes in cognition.

Majority of older adults with cognitive impairment still drive

The majority of older adults with cognitive impairment are still driving, despite concerns raised by caregivers and others, a study finds. Researchers say it’s best for caregivers to start conversations surrounding driving earlier while the care recipient is able to understand and actively participate in the discussion.

Insomnia, sleep apnea contribute to reports of cognitive decline in women with multiple sclerosis

Sleep disorders such as insomnia and sleep apnea may contribute to perceived cognitive decline, including ability to follow instructions and memory, in women with multiple sclerosis. Cognitive decline affects up to 70% of people with MS.

Researchers Find That Brains With More Vitamin D Function Better

Researchers at Tufts University have completed the first study examining levels of vitamin D in brain tissue, specifically in adults who suffered from varying rates of cognitive decline. They found that members of this group with higher levels of vitamin D in their brains had better cognitive function.

Daily Multivitamin May Improve Cognition and Possibly Protect Against Decline

New research from Wake Forest University School of Medicine shows that taking a daily supplement may improve cognition in older adults. In the study, researchers estimated that three years of multivitamin supplementation roughly translated to a 60% slowing of cognitive decline (about 1.8 years).

Moderate drinking linked to brain changes and cognitive decline

Consumption of seven or more units of alcohol per week is associated with higher iron levels in the brain, according to a study of almost 21,000 people publishing July 14th in the open access journal PLOS Medicine. Iron accumulation in the brain has been linked with Alzheimer’s and Parkinson’s diseases and is a potential mechanism for alcohol-related cognitive decline.

When it Comes to Preventing Alzheimer’s, Women and Men are Not Created Equal

A study is the first to examine if sex significantly affects cognitive outcomes in people who follow individually-tailored, multi-domain clinical interventions. The study also determined whether change in risk of developing cardiovascular disease (CVD) and Alzheimer’s disease (AD), along with blood markers of AD risk, also were affected by sex. Results showed that while care in an Alzheimer’s Prevention Clinic setting is equally effective at improving cognitive function in both women and men, the personally-tailored interventions used by the researchers led to greater improvements in women compared to men across AD and CVD disease risk scales, as well blood biomarkers of risk such as blood sugar, LDL cholesterol, and the diabetes test HbA1C. Findings are important because women are disproportionately affected by AD and population-attributable risk models suggest that managing risk factors can prevent up to one-third of dementia cases.

Study: Adding Color to Your Plate May Lower Risk of Cognitive Decline

A new study shows that people who eat a diet that includes at least half a serving per day of foods high in flavonoids like strawberries, oranges, peppers and apples may have a 20% lower risk of cognitive decline. The research is published in the July 28, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study looked at several types of flavonoids, and found that flavones and anthocyanins may have the most protective effect.

Obesity and Cardiovascular Factors Combine to Cause Cognitive Decline in Latinos

Obesity is a major public health issue among Latinos, and a risk factor for Alzheimer’s disease. But in a new study, researchers at UC San Diego report that cardiometabolic abnormalities, such as hypertension, are more strongly associated with cognitive decline than obesity alone.
