Awareness of Memory Loss May Decline 2-3 Years Before Dementia Onset

People who will develop dementia may begin to lose awareness of their memory problems two to three years before the actual onset of the disease, according to a new study published in the August 26, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study also found that several dementia-related brain changes, or pathologies, are associated with the decline in memory awareness.

NIH Study Shows No Benefit of Omega-3 Supplements for Cognitive Decline

While some research suggests that a diet high in omega-3 fatty acids can protect brain health, a large clinical trial by researchers at the National Institutes of Health found that omega-3 supplements did not slow cognitive decline in older persons. With 4,000 patients followed over a five-year period, the study is one of the largest and longest of its kind. It was published today in the Journal of the American Medical Association.

Newly Discovered Brain Network Recognizes What’s New, What’s Familiar

ParietalMemoryNetwork-larger.jpg

New research from Washington University in St. Louis has identified a novel learning and memory brain network that processes incoming information based on whether it’s something we’ve experienced previously or is deemed to be altogether new and unknown, helping us recognize, for instance, whether the face before us is that of a familiar friend or a complete stranger.
