A new Cleveland Clinic-led study has identified mechanisms by which COVID-19 can lead to Alzheimers disease-like dementia. The findings, published in Alzheimers Research & Therapy, indicate an overlap between COVID-19 and brain changes common in Alzheimers, and may help inform risk management and therapeutic strategies for COVID-19-associated cognitive impairment.

In aging humans, aerobic exercise training increases gray and white matter volume, enhances blood flow, and improves memory function. ...

As visual recognition memory emerges in visual cortex, one circuit of inhibitory neurons supplants another and slower neural oscillations prevail, according to a new MIT study.

New research into Alzheimers disease (AD) suggests that secondary infections and new inflammatory events amplify the brains immune response and affect memory in mice and in humans -- even when these secondary events occur outside the brain.

Alzheimers & Dementia: The Journal of the Alzheimers Association. "We found that all causes of dementia are risk factors for severity and death in COVID-19 and that these risks are more pronounced for Alzheimers patients," Sérgio Verjovski-Almeida, principal investigator for the project and a professor at USPs Chemistry Institute, told Agência FAPESP. Dementia had already been identified as a risk factor for COVID-19, alongside other comorbidities, such as cardiovascular and respiratory dis...

Conservatives are less able to distinguish political truths from falsehoods than liberals, mainly because of a glut of right-leaning misinformation, a new national study conducted over six months shows. Researchers found that liberals and conservatives in the United States both tended to believe claims that promoted their political views, but that this more often led conservatives to accept falsehoods while rejecting truths.

 E-Mail Credit: MPI for Empirical Aesthetics A facial expression or the sound of a voice can say a lot about a persons emotional state; and how much they reveal depends on the intensity of the feeling. But is it really true that the stronger an emotion, the more intelligible it is? An international research team comprised of scientists from the Max Planck Institute for Empirical Aesthetics, New York University, and the Max Planck NYU Center for Language, Music, and Emotion (CLaME) has now disc...

 E-Mail Autistic peoples ability to accurately identify facial expressions is affected by the speed at which the expression is produced and its intensity, according to new research at the University of Birmingham. In particular, autistic people tend to be less able to accurately identify anger from facial expressions produced at a normal real world speed. The researchers also found that for people with a related disorder, alexithymia, all expressions appeared more intensely emotional. The que...
