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 […]

PET imaging with special tracer can detect, diagnose early Alzheimer’s disease

The effort to find ways to detect and diagnose preclinical Alzheimer’s disease (AD) has taken a big step forward with the use of positron emission tomography (PET), a “nuclear medicine” for imaging processes in the body, when PET is used with a special ‘tracer’ that binds to the amyloid plaques in the brain that are […]

Will heart medication help treat Alzheimer’s disease?

A new study from Örebro University, published in Science Signaling, shows that heart medication reduces the build-up of plaque in the brain’s blood vessels in mice. The question is if this is true also in humans; if the answer is yes, it might bring scientists a step closer to developing a medicine against Alzheimer’s disease. […]

Should older people and those with dementia have their licences revoked?

One in ten people over the age of 65 and three in ten people over the age of 85 have dementia. As a degenerative and debilitating disease, people with dementia find they are unable to perform some of the everyday tasks they used to do very well. One of the major dilemmas for families and […]
