An Antidepressant to Prevent Alzheimer’s?

July 21, 2014

Scientists report promising results from a small clinical trial of an SSRI drug to lower amyloid beta levels, but years of further tests lie ahead.

How Far Should Brain Researchers Go?

July 14, 2014

How much should we enhance our brains, how far should we go to treat risky pre-term pregnancies, and when can we morally do research on people having surgery for something else were among the topics at the William Safire Seminar on Neuroethics.

Obesity Linked to Changes in Brain’s White Matter Structure—and Cognition

July 7, 2014

Reducing fat levels in obese mice through exercise or surgery appears to result in better cognitive performance.

A Purposeful Life is a Healthier Life

June 26, 2014

Results from programs like Experience Corps suggest that having a goal or purpose helps protect against cognitive decline as we age.

‘Smart’ Drugs Alter Developing Brain

June 23, 2014

Though many “normal” people—students, lawyers, doctors—are taking drugs that may enhance cognitive function, there is little research into how these drugs affect non-disordered brains. A research review suggests that using cognitive-enhancing drugs may have unintended and quite negative consequences, especially in youngsters.

A Fountain of Youth for the Brain?

June 12, 2014

Scientists have reported promising rejuvenation experiments on mouse brains-but it isn't clear that such results can be translated usefully into human therapies.

NIH Calls for ‘Sea Change’ Regarding Sex Differences in Research

June 9, 2014

New policy for US National Institutes of Health funding will require that researchers propose studies that have balance of male and female cells, tissues, or animals.

Uncovering the Mysteries of Myelin

May 28, 2014

Now that researchers have the technology to test the hypothesis that myelin is a simple, regular axonal insulator, they find it isn’t true. Now the fun begins.

The Neuroprotective Effects of Education

May 22, 2014

Research published in the past few years suggests that longer years of formal study can strengthen the brain, making it more resistant to the ravages of old age—and perhaps mitigating the damage that occurs after traumatic brain injury.

A Key Defender of the Aging Brain?

May 20, 2014

The loss of the REST protein from neurons appears to be an important early event in neurodegenerative disease. Researchers now are looking for ways to restore it in the elderly.

 

First Language Learned, Hearing Status Affects Brain Structure

May 15, 2014

Deaf people who learned American Sign Language first show differences in brain structure compared with deaf people who learned to lip-read English first.

Glia: Earning Some Respect

May 6, 2014

Either as “handmaidens to neurons” or as actors in their own right, researchers find glial cells show powerful effects in mouse models of disease.

Neuroimaging Offers Potential for Early Diagnosis of Neurodegenerative Disorders

April 29, 2014

Using DTI, researchers find brain "biomarkers" that identify who has the at-risk variation of a gene for a late onset fragile X-associated syndrome. Others are using PET scanning to track the plaques associated with Alzheimer's years before symptoms show.

 

Gene Variants May Help Predict Recovery from TBI and PTSD

April 22, 2014

Researchers investigating the gene that directs the building of protein BDNF find that people with one variation seem to recover more slowly and less well than those with other variations.

Glycotoxicity: A New Risk Factor for Alzheimer’s?

April 16, 2014

Advanced glycation end-products from high-temperature cooking have already been linked to diabetes and heart disease, and scientists are now looking at their effects on the brain.
