Sometimes, however, the twitching or jerking of your hand or foot—a condition known as sleep myoclonus—is enough to awaken you. Or your

The science of whether some dietary choices are really “brain food” continues to unfold. Given the long time frames of conditions such as Alzheimer’s disease and other dementias, it’s challenging to prove any cause-and-effect relationship between specific foods and brain health. Most such associations are drawn from observational studies, in
If you were to look only at the record of pharmaceutical interventions against Alzheimer’s disease and other forms of dementia, the picture would be bleak. “’The history of the results of clinical trials has been a history of disappointment,” says Keith Fargo, PhD, director of scientific programs and outreach for
The moment your doctor tells you that you’ll have to undergo a surgical procedure can be a frightening, confusing, and stressful experience. All kinds of thoughts will cross your mind—it’s natural to worry about the skills of your medical team, the operation’s outcome, and potentially high medical bills that will

The looming threat of losing memory and other mental abilities is frightening for many older adults. It’s helpful to understand what Alzheimer’s disease is, and also what it is not.
For example, from
A growing body of evidence indicates that the underlying neuropathological mechanisms associated with Alzheimer’s disease (AD) begin 10 years or more before cognitive impairment manifests.
In 1995 the BIOCARD study (Biomarkers of Cognitive Decline among Normal Individuals) was developed to identify people who could be participants in AD clinical trials, as well
TRAUMATIC HEAD INJURY DOES NOT RAISE RISK FOR DEMENTIA
It has long been believed that traumatic head injury (TBI) involving damage to the brain is associated with increased risk for dementia. However, a new study published in the Nov. 21, 2012 online edition of the Journal of Neurology, Neurosurgery & Psychiatry
