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...
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...
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 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...
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...
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 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...
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...
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...
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...
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....
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 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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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,...
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...
