Depression, behavior changes may be earliest symptoms of Alzheimer’s disease

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.

Paradoxical effect of certain antidepressants discovered

Why some antidepressants may initially worsen symptoms – New research helps explain a paradoxical effect of certain antidepressants–that they may actually worsen symptoms before helping patients feel better. These findings may help investigators fix the problem as well as create new classes of drugs to treat depression.

Anxiety can damage brain and increases Alzheimer’s disease risk

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.

Thousand genes differences contribute to autism risk

Changes in scores of genes contribute to autism risk — Newfound genetic differences provide many hints at causes – Small differences in as many as a thousand genes contribute to risk for autism or autism spectrum disorder (ASD). This new study examined data on several types of rare, genetic differences in more than 14,000 DNA samples from parents, affected children, and unrelated individuals.

Dietary cocoa flavanols reverse age related memory decline

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.

Fitness linked to heart health and then to brain health

Train your heart to protect your mind — New study links cardiovascular health to cognitive changes as we age – Exercising to improve our cardiovascular strength may protect us from cognitive impairment as we age. This is revealed in a new study by researchers at the University of Montreal and its affiliated Institut universitaire de gératrie de Montréal Research Centre.

3-D brain-like tissue developed by US bioengineers

Bioengineers create functional 3-D brain-like tissue — Tissue model could change the way scientists study the brain in vitro-NIH study – US Bioengineers have created three-dimensional brain-like tissue that functions like and has structural features similar to tissue in the rat brain and that can be kept alive in the lab for more than two months.
