Women with Genetic Risk of Alzheimer’s More Likely than Men to Develop It Between Age 65 and 75

White women whose genes put them at risk of developing Alzheimer’s disease are more likely than white men with similar risk genes to be diagnosed between the ages of 65 and 75, a study drawing on...

Stopping Alzheimer’s Years Before It Starts

Researchers at the Keck School of Medicine of USC are tackling the sixth-leading cause of death in the United States—Alzheimer’s disease—with a new study that intervenes decades before the disease develops. The school is...

AI COULD HELP DIAGNOSE ALZHEIMER’S DISEASE A DECADE EARLIER THAN DOCTORS CAN

A devastating chronic neurodegenerative disease, Alzheimer’s disease (AD) currently affects around 5.5 million people in the United States alone. Causing progressive mental deterioration, it ultimately advances to impact basic bodily functions such as walking and...

Intermittent electrical brain stimulation improves memory

Intermittent electrical stimulation of an area deep inside the brain that degenerates in Alzheimer’s appears to improve working memory, scientists report. Conversely, continuous deep brain stimulation, like the type used for Parkinson’s...

Blood Test Seen to Identify Alzheimer’s with Accuracy

A new type of analysis allowed researchers to use a blood test to help to identify patients with Alzheimer’s in a group of people with neurodegenerative diseases, a study published in the journal...

Moving When Young May Strengthen the Adult Brain

Being active in youth may change the inner workings of brain cells much later in life and sharpen some types of thinking, according to a remarkable new neurological study involving rats. The study...

Women at Risk for Alzheimer’s Face Critical 10-Year Window

Women with a genetic predisposition for Alzheimer’s disease face a 10-year window when they have far greater chances of developing the disease than men with similar genetic risks, a new analysis suggests. That window...

All Signs Point to Tau Tangles as the Culprit in Fading Memory

The two hallmark pathologies of Alzheimer’s disease, amyloid plaques and tau tangles, play different roles in disease progression. Accumulating research suggests that amyloid plaques kick off the disease, precipitating the spread of tau, which then...

CSF and Brain Markers Highlight Different Facets of Dementia

While biomarkers have opened a window onto Alzheimer’s pathogenesis, the view has remained cloudy. At the Alzheimer’s Association International Conference 2017 held July 16-20 in London, the number of biomarker talks was noteworthy, with nearly...

Serotonin may play important role in brain-aging

Recent findings suggested the serotonin system may be an effective target for prevention and treatment of mild cognitive impairment. “Now that we have more evidence that serotonin is a chemical that appears affected early in...

Smell test may identify Alzheimer’s risk

By the time you start losing your memory, it’s almost too late. That’s because the damage to your brain associated with Alzheimer’s disease (AD) may already have been going on for as long as twenty years....

Eye scan reveals Alzheimer’s years before symptoms appear

For decades, the only way to officially diagnose Alzheimer’s disease was by analysing a patient’s brain during a postmortem. More recently, physicians have been able to use positron emission tomography scans of the brains of living people...

The female brain is more active than the male brain

The results of the largest functional brain imaging survey ever conducted suggest female brains are more active than male brains. Scientists surveyed the results of 46,034 brain imaging studies involving single-photon emission computed tomography, or...

Can Brain Bacteria Contribute to Alzheimer’s?

Patients with Alzheimer’s disease may have more bacteria — and different types — in their brains, compared to the general population, according to results of a new study. These findings support that...

Cardiovascular Factors May Up Risk for Alzheimer’s

In a new study, researchers have discovered a link between mild cognitive impairment, elevated cardiovascular risk factors, and Alzheimer’s disease. Advances have been made toward determining the probability of developing dementia as scientists have...

Walnuts may promote health by changing gut bacteria

Research led by Lauri Byerley, PhD, RD, Research Associate Professor of Physiology at LSU Health New Orleans School of Medicine, has found that walnuts in the diet change the makeup of bacteria in the gut, which suggests...

Data Mining Strategy Shows Promise in Alzheimer’s Treatment

The push to develop treatments for Alzheimer’s disease has been a promising and disappointing endeavor over the past two decades, yielding a greater understanding of the disease yet still failing to generate successful...

Cell Death Mechanism Involved in Other Diseases Plays Role in Development of Alzheimer’s

A cell death mechanism linked to neuron loss in ALS and stroke also plays a role in neuron loss in Alzheimer’s, a study reports. The insight could lead to ways to stop neuron death...

Blood test identifies key Alzheimer’s marker

A new study led by researchers at Washington University School of Medicine in St. Louis suggests that measures of amyloid beta in the blood have the potential to help identify people with altered levels of...

Estrogen levels linked to depression risk in women

  Depression is a constant sadness affecting our activity level, behavior, thoughts, feelings, and sense of well-being. Those affected often feel empty and worthless, which could lead to erratic behavior or even suicide. There are numerous...

Risk Tool Helps Discern When Complaints about Memory Matter

A biomarker-based personalized risk estimate may help predict which patients with subjective cognitive decline (SCD) will progress to dementia, Dutch researchers reported here. A model that takes into account age, Mini Mental State Exam...

Second Thoughts About Memory Complaints

They were once dismissed as anxieties of the “worried well” — but now that subjective memory complaints may be a valuable tool for recruiting patients into disease-modifying drug trials, researchers are beginning to pay...

Adding Pounds in Adulthood Ups Major Health Risks

Gaining a small amount of weight each year during early and middle adulthood can add up to major health risks later in life, a large cohort study found. From early adulthood to age 55,...

Hearing and language problems could be forerunners of cognitive decline

Scientists have traced the roots of dementia back to midlife, a time when hearing loss and changes in speech patterns may signal the onset of cognitive decline. In research presented Monday at the Alzheimer’s...
