A machine learning method analyzing large amounts of health information has potential in assessing the risk of cognitively healthy older people for later dementia, according to research published in the Journal of Alzheimer’s Disease. The new risk assessment tool also presents the individual risk profile in a quickly interpretable visual form. Preventing dementia is a […]

In a hopeful sign for the health of the nation’s brains, the percentage of American seniors with dementia is dropping, a new study finds. The downward trend has emerged despite something else the study shows: a rising tide of three factors that are thought to raise dementia risk by interfering with brain blood flow, namely […]

Taking a pill that prevents the accumulation of toxic molecules in the brain might someday help prevent or delay Alzheimer’s disease, according to scientists at Baylor College of Medicine, Texas Children’s Hospital and Johns Hopkins University School of Medicine. The study, published in Cell Press journal Neuron, took a three-pronged approach to help subdue early […]

Women may have better verbal memory skills than men even when their brains show the same level of problems metabolizing glucose, which occurs in people with Alzheimer’s disease, according to research published in the October 5, 2016, online issue of Neurology®, the medical journal of the American Academy of Neurology. “Women perform better than men […]

Among a group of older women, self-reported caffeine consumption of more than 261 mg per day was associated with a 36 percent reduction in the risk of incident dementia over 10 years of follow-up. This level is equivalent to two to three 8-oz cups of coffee per day, five to six 8-oz cups of black […]

It’s over a hundred years since the first case of Alzheimer’s disease was diagnosed. Since then we’ve learned a great deal about the protein ‘tangles’ and ‘plaques’ that cause the disease. How close are we to having effective treatments — and could we even prevent dementia from occurring in the first place? You may have […]

Relying on clinical symptoms of memory loss to diagnose Alzheimer’s disease may miss other forms of dementia caused by Alzheimer’s that don’t initially affect memory, reports a new Northwestern Medicine study. “These individuals are often overlooked in clinical trial designs and are missing out on opportunities to participate in clinical trials to treat Alzheimer’s,” said […]

A test that can detect Parkinson’s disease in the early stages of the illness has moved a step closer. Scientists have developed a way of detecting a molecule linked to the condition in samples of spinal fluid from patients. Experts say that the test needs to be validated with a larger sample group but they […]

New research suggests that Alzheimer’s disease may trigger increased expression of an enzyme called lysozyme, which attempts to counteract amyloid build-up in the brain. Investigators found that the expression of lysozyme was increased in the brains of both transgenic mice and humans with Alzheimer’s disease. Furthermore, lysozyme had favorable effects when expressed in different fly […]

Several scientific studies have indicated that nicotine may be beneficial for memory function. Scientists from the Institut Pasteur and the CNRS set out to shed further light on the properties attributed to nicotine — which is known to have an adverse effect on health — by determining the precise structure of the nicotinic receptors in […]
