How Brain Regions Involved in Wakeful Rest May Play a Role in the Risk for Alzheimer’s Disease
Daydreaming puts the brain in a state of wakeful rest, allowing the connection of brain regions known as the Default Mode Network (DMN) to interact. The DMN is now a topic of investigation for researchers trying to understand why women are at a higher risk for Alzheimer's Disease than men.
SLEEP-SMART Intervention Shows Promising Results for Women Suffering from Sleeping Problems, Depression, and Anxiety
Preliminary data indicate SLEEP-SMART can improve sleep patterns, show associated reductions in symptoms of depression and anxiety, and improve the functioning of brain circuits important in emotional and cognitive health.
Research Begun by WHRY Continues to Show Possible Pathway to Derail Dementia
Research is revealing the mechanisms that underlie the role of estradiol in memory so that next generation treatments for Alzheimer's disease and other dementias can specifically target these mechanisms and avoid the potential for negative side effects of systemic estrogen therapy.
Alzheimer's Disease Research Center will hold a research day on Feb. 12
The Alzheimer's Disease Research Center will be hosting a Research Day, which will include a series of lectures on current research studies on Alzheimer's Disease. The following Investigators will be presenting: Christopher van Dyck, MD; Jason Cai, PhD; Amy Arnsten, PhD; Morgan Levine, PhD; Nenad Sestan, MD,PhD; In Hyun Park, PhD; and Flora Vaccarino, MD.
How do we lose memory? A STEP at a time, researchers say
In mice, rats, monkeys, and people, aging can take its toll on cognitive function. A new study by researchers at Yale and Université de Montréal reveal there is a common denominator to the decline in all of these species — an increase in the level of the molecule striatal-enriched phosphatase, or STEP.
Research in the news: Hyperactive neurons may be culprit in Alzheimer’s
A long-term reduction in neuronal activity reduces amyloid plaques associated with Alzheimer’s disease, Yale University researchers have found. The study, using mouse models of Alzheimer’s, found the opposite is also true — triggering an increase in neuronal activity spurs creation of plaques and toxic amyloid beta peptides believed to trigger the disease.
Immune cells are an ally, not enemy, in battle against Alzheimer’s
In Alzheimer’s disease (AD), β-amyloid plaques are tightly enveloped by microglia but the significance of this phenomenon is unknown. Here the authors used confocal and in vivo two-photon imaging in AD mouse models and revealed that microglia constitute a physical barrier that prevents the formation of neurotoxic hotspots of protofibrillar β-amyloid and shields adjacent neurons and synapses from the toxic effect of amyloid plaques
Alzheimer’s missing link found: Is a promising target for new drugs
Yale School of Medicine researchers have discovered a protein that is the missing link in the complicated chain of events that lead to Alzheimer’s disease, they report in the Sept. 4 issue of the journal Neuron. Researchers also found that blocking the protein with an existing drug can restore memory in mice with brain damage that mimics the disease.
Can Diabetes Drugs Lower the Risk of Age-Related Dementia?
In patients with diabetes, recent studies have found a positive correlation between taking metformin, a blood sugar medication, and lowered risk of dementia. While promising, this link is not definitive, and experts like Yale's Arman Fesharaki-Zadeh, MD, PhD, advise that patients maintain a healthy weight and diet and exercise in order to preserve cognitive wellbeing.Source: WebMD
