Aging adults who report being very sleepy during the day were nearly three times more likely than those who didn’t to have brain deposits of beta amyloid, a protein that’s a hallmark for Alzheimer’s disease, years later. The finding, published on Sept. 5 in the journal SLEEP, adds to a growing body of evidence that poor quality sleep could encourage ...

Antiepileptic drugs may increase the risk of stroke among persons with Alzheimer’s disease, said a new study from the University of Eastern Finland. The risk remains the same whether the drugs are old or new antiepileptic drugs, said the study published in the Journal of the American Heart Association. The study, conducted at the University of Eastern Finland and funded ...

A Japanese research group has proposed that failure to recognize or memorize human faces in the short term could be early stage of dementia. The elderly with mild cognitive impairment (MCI) suffer from weakened ability to recognize faces when compared to healthy elderly people. When trying to memorize, their gaze is also different, suggest Japanese researchers. Alzheimer’s disease, the most ...

Cedars-Sinai neuroscience investigators have found that Alzheimer’s disease affects the retina — the back of the eye — similarly to the way it affects the brain. The study also revealed that an investigational, noninvasive eye scan could detect the key signs of Alzheimer’s disease years before patients experience symptoms. Using a high-definition eye scan developed especially for the study, researchers ...

In old-age, the frequent occurrence of B12 deficiency could lead to dementia and even Alzheimer’s disease as the body metabolism fails to absorb the vitamin from the diet, requiring an early medical intervention. To help detect B12 deficieny early, Australia’s University of Adelaide researchers have developed a first of its kind optical sensor using a technique called Raman spectroscopy that ...
