Diabetes Drug Shows Promise in Reducing Alzheimer's Disease in an Experimental Model
BOSTON; March 24, 2014—Researchers from Boston University School of Medicine (BUSM) have found that the diabetic drug, pramlintide, reduces amyloid-beta peptides, a major component of Alzheimer's disease (AD) in the brain and improves learning and memory in two experimental AD models. These findings, which appear online in Molecular Psychiatry, also found AD patients have a lower level of amylin in blood compared to those without this disease. These results may provide a new avenue for both treatment and diagnosis of AD.

Don't Judge Older Drivers by Age, Study Says
January 28, 2014—Encouraging older drivers to self-regulate their driving rather than revoking their licence based on age, has the potential to improve their safety and maintain their independence, aQUT study has found. Dr. Ides Wong, from QUT's Centre for Accident Research & Road Safety—Queensland (CARRS-Q), said a person's age was not an accurate predictor of their driving ability. "People do not wake up on their 75th birthday a worse driver than they were the day before, which is what current age-based testing assumes," Dr Wong said.

Brain Area Attacked by Alzheimer's Links Learning and Rewards
Crucial linkage normally helps brain step up to new challenges
DURHAM, NC; December 18, 2013—One of the first areas of the brain to be attacked by Alzheimer's disease is more active when the brain isn't working very hard, and quiets down during the brain's peak performance. The question that Duke University graduate student Sarah Heilbronner wanted to resolve was whether this brain region, called the posterior cingulate cortex, or PCC, actively dampens cognitive performance, say by allowing the mind to wander, or is instead monitoring performance and trying to improve it when needed.

Novel Algorithm Detects Early Signals of Alzheimer’s Disease in Everyday Motion Behavior
Rostock, Germany, October 5, 2013—The projected substantial increase in Alzheimer’s disease due to the higher life expectancy in modern societies is one of the great future challenges of health care systems worldwide. Alzheimer’s disease leads to significant changes in the temporal structure of activities that impair everyday activities. Abnormal motion behavior and degeneration of the sleep-waking cycle are among the most severe behavioral symptoms. An early detection and even a prediction of these behaviors would allow a timely onset of interventions that aim to delay the manifestation or exacerbation of symptoms and reduce the need of institutionalized care.

Study Suggests Iron is at Core of Alzheimer's Disease
Findings challenge conventional thinking about possible causes of disorder
August 20, 2013—Alzheimer's disease has proven to be a difficult enemy to defeat. After all, aging is the No. 1 risk factor for the disorder, and there's no stopping that.
Most researchers believe the disease is caused by one of two proteins, one called tau, the other beta-amyloid. As we age, most scientists say, these proteins either disrupt signaling between neurons or simply kill them. Now, a new UCLA study suggests a third possible cause: iron accumulation.

New Drugs May Offer Hope for Alzheimer's Patients
Scientists have unveiled the mechanisms behind two classes of compound currently being tested in clinical trials
August 2, 2013—The future is looking good for drugs designed to combat Alzheimer's disease. Scientists at Ecole Polytechnique Fédérale de Lausanne (EPFL) have unveiled how two classes of drug compounds currently in clinical trials work to fight the disease. Their research suggests that these compounds target the disease-causing peptides with high precision and with minimal side-effects. At the same time, the scientists offer a molecular explanation for early-onset hereditary forms of Alzheimer's, which can strike as early as thirty years of age. The conclusions of their research, which has been published in the journal Nature Communications, are very encouraging regarding the future of therapeutic means that could keep Alzheimer's disease in check.
During their investigation, the scientists also identified possible causes behind some hereditary forms of Alzheimer's disease.

Living Longer, Living Healthier
Research shows that people are remaining healthier later in life
July 29, 2013—A new study, conducted by David Cutler, the Otto Eckstein Professor of Applied Economics, shows that, even as life expectancy has increased over the past two decades, people have become increasingly healthier later in life.
"With the exception of the year or two just before death, people are healthier than they used to be," Cutler said. "Effectively, the period of time in which we're in poor health is being compressed until just before the end of life. So where we used to see people who are very, very sick for the final six or seven years of their life, that's now far less common. People are living to older ages and we are adding healthy years, not debilitated ones."

Senior Moment? Stereotypes about Aging Can Hurt Older Adults' Memory
Scientists show that attributing every forgetful moment to getting older can actually worsen memory problems—and reveal a surprising twist that can improve performance
July 1, 2013—Of the many negative stereotypes that exist about older adults, the most common is that they are forgetful, senile and prone to so-called "senior moments." In fact, while cognitive processes do decline with age, simply reminding older adults about ageist ideas actually exacerbates their memory problems, reveals important new research from the USC Davis School of Gerontology.

Drugs Found to Both Prevent and Treat Alzheimer's Disease in Mice
May 21, 2013—Researchers at the University of Southern California (USC) have found that a class of pharmaceuticals can both prevent and treat Alzheimer’s disease in mice.
The drugs, known as “TSPO ligands,” are currently used for certain types of neuroimaging.
“We looked at the effects of TSPO ligand in young adult mice when pathology was at an early stage and in aged mice when pathology was quite severe,” said lead researcher Christian Pike of the USC Davis School of Gerontology. “TSPO ligand reduced measures of pathology and improved behavior at both ages.”

Cinnamon Compound Could Potentially Prevent Alzheimer's
Santa Barbara; May 23, 2013––Cinnamon: Can the red-brown spice with the unmistakable fragrance and variety of uses offer an important benefit? The common baking spice might hold the key to delaying the onset of––or warding off––the effects of Alzheimer's disease.
That is, according to Roshni George and Donald Graves, scientists at the University of California, Santa Barbara. The results of their study, "Interaction of Cinnamaldehyde and Epicatechin with Tau: Implications of Beneficial Effects in Modulating Alzheimer's Disease Pathogenesis," appears in the online early edition of the Journal of Alzheimer's Disease, and in the upcoming Volume 36, issue 1 print edition.
Alzheimer's disease is the most common form of dementia, a neurodegenerative disease that progressively worsens over time as it kills brain cells. No cure has yet been found, nor has the major cause of Alzheimer's been identified.
