Evidence supporting three interventions that might slow cognitive decline and the onset of dementia is encouraging — Cognitive training, blood pressure management for people with hypertension, and increased physical activity all show modest evidence that they can help prevent cognitive decline and dementia. “There is good cause for hope that in the next several years … Read more
Saliva may hold the keys to understanding a person’s likelihood of developing Alzheimer’s, even among those who don’t yet have memory and thinking problems associated with the disease. Knowing that Alzheimer’s typically coexists with certain metabolic disorders, Shraddha Sapkota, a neuroscience PhD student at the U of A, along with psychology professor Roger Dixon and … Read more
Depression, behavior changes may start in Alzheimer’s even before memory changes – Depression and other behavior changes may show up in people who will later develop Alzheimer’s disease even before they start having memory problems, reported by researchers in the medical journal of the American Academy of Neurology.
Anxiety can damage brain — Accelerate conversion to Alzheimer’s for those with mild cognitive impairment – People with mild cognitive impairment (MCI) are at increased risk of converting to Alzheimer’s disease within a few years, but a new study warns the risk increases significantly if they suffer from anxiety.
Dietary flavanols reverse age-related memory decline — Findings strengthen link between specific brain region and normal memory decline – Dietary cocoa flavanols—naturally occurring bioactives found in cocoa—reversed age-related memory decline in healthy older adults, revealed by researchers in Nature Neuroscience.
First biological marker for major depression could enable better diagnosis and treatment – Teenage boys who show a combination of depressive symptoms and elevated levels of the ‘stress hormone’ cortisol are up to fourteen times more likely to develop major depression than those who show neither trait, according to a research study published.
Excess weight linked to brain changes that may relate to memory, emotions, and appetite – Being overweight appears related to reduced levels of a molecule that reflects brain cell health in the hippocampus, a part of the brain involved in memory, learning, and emotions, and likely also involved in appetite control, revealed by researchers.
Cleveland Clinic identifies mechanism in Alzheimer’s-related memory loss — Study uncovers role of Neuroligin-1 protein – Cleveland Clinic researchers have identified a protein in the brain that plays a critical role in the memory loss seen in Alzheimer’s patients. The protein – Neuroligin-1 (NLGN1) – is known to be involved in memory formation; this is the first time it’s been linked to amyloid-associated memory loss.
High good and low bad cholesterol levels are healthy for the brain, too – High levels of “good” cholesterol and low levels of “bad” cholesterol are correlated with lower levels of the amyloid plaque deposition in the brain that is a hallmark of Alzheimer’s disease, UC Davis researchers have found.
Vitamin E May Delay Decline in Mild-to-Moderate Alzheimer’s Disease — Study Shows Benefit in Activities of Daily Living and Savings in Caregiver Time with Vitamin E – A new research suggests that alpha tocepherol, fat-soluble Vitamin E and antioxidant, may slow functional decline (problems with daily activities such as shopping, preparing meals, planning, and traveling) in patients with mild-to-moderate Alzheimer’s disease and decrease caregiver burden.
