Memory loss not enough to diagnose Alzheimer’s

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 […]

Parkinson’s study could pave way for early detection test

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 treatment strategy against Alzheimer’s disease?

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 […]

Alzheimer’s: Nicotinic receptors as a new therapeutic target

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 […]

From pollution to caffeine intake: Researcher reveals dementia risks

Dementia strikes one in 14 people in the UK over 65, and 47 million people worldwide.Yet scientists are still urgently trying to find why the disease affects some but not others. Dr Ruth Peters, a neuropsychologist from Imperial College London, is one such scientist. Her research involves trying to pinpoint the risk factors for dementia. […]

Could a Fluffy Pet Robot Revolutionize Dementia Care?

  With no cure on the horizon and a growing number of cases around the world, researchers are studying whether robots could replace costly medication in the treatment of dementia—and also improve the quality of care in nursing homes. With its long, batting eyelashes and wails for attention, the furry seal robot called Paro almost […]

Study suggests ‘use it or lose it’ to defend against memory loss

Iowa State University researchers have identified a protein essential for building memories that appears to predict the progression of memory loss and brain atrophy in Alzheimer’s patients. Auriel Willette, an assistant professor of food science and human nutrition; and Ashley Swanson, a graduate research assistant, say the findings also suggest there is a link between […]

Promising new methods for early detection of Alzheimer’s disease

New methods to examine the brain and spinal fluid heighten the chance of early diagnosis of Alzheimer’s disease. Results from a large European study, led by researchers at the Karolinska Institutet, are now published in the medical journal BRAIN. These findings may have important implications for early detection of the disease, the choice of drug […]

Cerebrovascular disease linked to Alzheimer’s

While strokes are known to increase risk for dementia, much less is known about diseases of large and small blood vessels in the brain, separate from stroke, and how they relate to dementia. Diseased blood vessels in the brain itself, which commonly is found in elderly people, may contribute more significantly to Alzheimer’s disease dementia […]

Certain leisure activities may reduce post-surgical delirium among older adults

Delirium, or the medical term for experiencing sudden confusion, is upsetting for both older adults and their families. In fact, it is one of the most common complications older adults face after surgery (a time often referred to as the “post-operative” period). Researchers believe that older adults who have higher levels of “cognitive reserve” may […]
