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...
Four studies being presented at the Alzheimer’s Association International Conference 2017 are highlighting the potential benefits of certain diets and how they can support healthy brain ageing and help to reduce dementia risk. There is a body...
Men and women react differently to compounds associated with immune system response to bipolar disorder, according to an international team of medical researchers. The findings suggest that bipolar disorder could one day be diagnosed by measuring biological...
Immune cells called perivascular macrophages (green) are observed in close contact with blood vessels in the brain (red). When activated by plaque deposits from the peptide amyloid-beta, which are a hallmark of Alzheimer’s disease, perivascular macrophages...
A group of researchers from diverse Spanish public entities, including UPM, has developed the bases of a new model to better classify patients when it comes to prescribing anabolic hormone supplementation. A female researcher from Faculty of...
According to a study encompassing the entire Finnish population, traumatic brain injury associated with an increased risk for dementia in working-age adults. Yet, no such relationship was found between traumatic brain injury and later onset of Parkinson’s...
Researchers from the Medical Research Council’s Laboratory of Molecular Biology, Cambridge, UK, have solved the structure of the dementia-causing ‘tau’ protein in unprecedented detail. Using brain tissue from a deceased 74-year-old Alzheimer’s patient, researchers...
The way we walk can say a lot about us; fast walkers are seen as individuals with high energy, while slow walkers are seen as more relaxed. Our gait can reveal more than just...
Dr. Efraim Jaul, director of geriatric skilled nursing at Herzog Hospital in Jerusalem, noticed that many patients with dementia — and especially those with Alzheimer’s disease — seemed more prone to developing pressure ulcers (bedsores). It occurred...
Alzheimer’s disease affects about 5.5 million Americans — a number that’s expected to balloon to 13.8 million by 2050. As the most common cause of dementia, it’s the sixth leading cause of death in the US,...
In the last decade, mounting evidence has linked seizure-like activity in the brain to some of the cognitive decline seen in patients with Alzheimer’s disease. Patients with Alzheimer’s disease have an increased risk of epilepsy and nearly...
Scientists studying Alzheimer’s have found that staying moderately active can lead to healthier brain functions in those at risk of developing the disease, potentially giving us another clue how to beat the condition. In...
Older adults with elevated levels of brain-clogging plaques — but otherwise normal cognition — experience faster mental decline suggestive of Alzheimer’s disease, according to a new study led by the Keck School of Medicine...
