Taking a low-dose aspirin once a day does not reduce the risk of thinking and memory problems caused by mild cognitive impairment or probable Alzheimer's disease, nor does it slow the rate of cognitive decline, according to a large study published in the March 25, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Many of us are spending a lot of time looking at our hands lately and we think we know them pretty well. But research from York University's Centre for Vision Research shows the way our brains perceive our hands is inaccurate.

Certain middle-aged and older adults, especially women who tend to disengage from difficult tasks and goals after they retire, may be at greater risk of cognitive decline as they age, according to research published by the American Psychological Association.

The strength of alpha brain waves reveals if you are about to make a biased decision, according to research recently published in JNeurosci.

Resolvins are lipids that 'resolve' the inflammation that normally follows injury or disease, returning the body back to normal. Therapeutic administration of one such resolvin can halt memory loss in a common preclinical model of Down syndrome, a finding that could also be relevant to memory loss in Alzheimer's disease, report researchers from the Medical University of South Carolina and elsewhere in Glia. This resolvin could enhance the body's ability to heal and resolve inflammation.

Using a mouse model, a pair of UC Riverside researchers demonstrated the formation of fear memory involves the strengthening of neural pathways between two brain areas: the hippocampus, which responds to a particular context and encodes it, and the amygdala, which triggers defensive behavior, including fear responses.

A new study has discovered that a lack of neuronal protein BIN1 leads to a defect in the transmission of chemical messages that activate brain cell communication allowing us to think, remember and behave. The preclinical research by a team from the University of South Florida Health (USF Health) Morsani College of Medicine and the University of Chicago provides new insights into how BIN1 may boost Alzheimer's disease risk.
