Scientist Are Beginning To See Alzheimer’s As A Whole Body Problem

There is still no known cure for this mind wasting disease as scientists still don’t understand what causes Alzheimer’s disease, but some are starting to see the disease as a whole body problem which manifests in the...

Optimism and Healthy Aging

Mounting evidence indicates specific associations between higher levels of optimism and healthier behaviors, reduced risk of chronic diseases, and lower mortality. Yet, for public health purposes, it is critical to consider how optimism may be related to...

Depression Can Increase Stroke Risk

Depressive symptoms were tied to an increased risk of ischemic stroke, a prospective cohort study of largely Hispanic older adults found. Over 14 years of follow-up, older adults who had elevated depressive symptoms were...

Not all sleep is equal when it comes to cleaning the brain

New research shows how the depth of sleep can impact our brain’s ability to efficiently wash away waste and toxic proteins. Because sleep often becomes increasingly lighter and more disrupted as we become older, the study reinforces...

Vitamin D Deficiency Weakens Brain Scaffolding

Removing vitamin D from the diet of healthy adult mice caused a significant drop in their ability to remember and learn, which researchers said was due to a pronounced reduction in perineuronal nets in the...

Alzheimer’s May Have Different Trajectory for Women

Women developed more tau pathology than men with similar amyloid burden, an analysis of cross-sectional data found. Across two cohorts of older cognitively normal adults, women with higher amyloid burden showed higher entorhinal cortical...

New drug raises hopes of reversing memory loss in old age

An experimental drug that bolsters ailing brain cells has raised hopes of a treatment for memory loss, poor decision making and other mental impairments that often strike in old age. The drug could be taken as a...

Midlife Inflammation Tied to Steeper Memory Decline

Midlife systemic inflammation was tied to steeper late-life cognitive decline, an analysis of data from the ARIC prospective cohort showed. Adults with elevated inflammation composite scores or elevated C-reactive protein (CRP) levels during midlife...

How Exercise Improves Memory And Protects Against Alzheimer’s

For decades, the scientific consensus has been that exercise improves both mental and physical health. Numerous studies over the years have demonstrated that this is the case, but some have also found that exercise plays...

A new culprit in cognitive decline in Alzheimer’s disease

It has long been known that patients with Alzheimer’s disease have abnormalities in the vast network of blood vessels in the brain. Some of these alterations may also contribute to age-related cognitive decline in people without dementia....

Alzheimer’s May Have Different Trajectory for Women

Women developed more tau pathology than men with similar amyloid burden, an analysis of cross-sectional data found. Across two cohorts of older cognitively normal adults, women with higher amyloid burden showed higher entorhinal cortical...

Elevated BP in Young Adults Tied to Gray Matter Shrinkage

Elevated BP was tied to lower gray matter volume in young adults ages 19 t0 40, researchers found. Gray matter volumes in adults ages 20 to 30 decreased as BP increased, with changes occurring...

Psychological Distress in Midlife Linked to Future Dementia

A new Danish study suggests that vital exhaustion as a sign of psychological distress may be a risk factor for future dementia. Danish researchers found that such distress in late midlife is associated...

Choline may help fight Alzheimer’s across generations

In a new study, researchers at the Biodesign Institute explore a safe and simple treatment for one of the most devastating and perplexing afflictions – Alzheimer’s disease (AD). Lead authors Ramon Velazquez and Salvatore Oddo, along...

New Genetic Risk Factors Discovered for Alzheimer’s Disease

A large-scale international study has discovered new genetic risk loci for Alzheimer’s disease, and researchers published their work in Nature Genetics. Combining genetic data on a large-scale and in a non-conventional manner resulted in the discovery...

Diversity in Alzheimer’s Research

Alzheimer’s disease may be twice as common in black Americans as in whites, and scientists don’t really know why. But new research uncovers a clue that suggests that diagnosing the brain-robbing disease may not be...

Exercise hormone may help combat Alzheimer’s

A hormone released during exercise may protect the brain against Alzheimer’s disease, research suggests. Irisin is a messenger protein generated by muscle tissue that is carried around the body in the bloodstream. The new evidence indicates that...

Enabling precision-medicine research for Alzheimer’s

Incorporating genetic diversity into a mouse model of Alzheimer’s disease resulted in greater overlap with the genetic, molecular and clinical features of this pervasive human disease, according to a study funded by the National Institute...

Could a Blood Test for Tau Diagnose Alzheimer’s?

Cerebrospinal fluid tau is an established Alzheimer’s disease biomarker, but efforts to develop a blood test for tau have been hampered by exceedingly low concentrations of the protein there. At least, until now, claims...

Food Really Does Affect How We Think

There have a been a number of convincing studies in recent years showing that the old adage “you are what you eat” is pretty accurate. But if you weren’t quite convinced to cut back...

Negative mood signals body’s immune response

Negative mood — such as sadness and anger — is associated with higher levels of inflammation and may be a signal of poor health, according to researchers at Penn State. The investigators found...

Nutrients found in Mediterranean diet linked to better brain connectivity & cognition

A new study links higher levels of several key nutrients in the blood with more efficient brain connectivity and performance on cognitive tests in older adults. The study, reported in the journal NeuroImage, looked at 32 key nutrients...

Parkinson’s disease – new research on the role of cognition and sex differences

Parkinson’s disease (PD) mainly affects the body’s motor system. It’s symptoms – which result from the long-term degeneration of the central nervous system – occur over time and include shaking, difficulty walking, slow movements, and rigidity. People with...

Possible Alzheimer’s Vaccine Discovered

Researchers at the University of Texas (UT) Southwestern Medical Center reported Tuesday that they have developed a vaccine that could arm the body to attack Alzheimer’s plaques and tangles before they even start to...
