Vitamin D Deficiency Increases Poor Brain Function After Cardiac Arrest by Sevenfold

October 20, 2014

New data presented at the European Society of Cardiology’s Acute Cardiovascular Care Association’s annual meeting suggests vitamin D deficiency could play a role in reduced brain function after a cardiac arrest. In a study of 53 patients at a hospital in Seoul, Korea, researchers found, for example, that 65% of those patients with low vitamin D had “poor neurological outcomes” six months later compared to just 23% of those patients with sufficient levels of vitamin D. Furthermore, among the low-vitamin D group, 29% had died at the six-month mark since cardiac arrest compared to none of the sufficient D group.

Mental Rest and Reflection Boost Learning, Study Suggests

October 21, 2014

University of Texas at Austin scientists, writing in the Proceedings of the National Academy of Sciences, reveal that resting reflection could boost the process of learning and memory formation. In two memory study groups, those subjects who used rest time to reflect on what they had already learned fared better in later tests than those who used rest time to think of other things. This research suggests that new information doesn’t necessarily interfere with standing memory, and that focused reflection could actually help “consolidate and strengthen” new information more efficiently.

Brain Scans Show Cause of Seasonal Affective Disorder

October 21, 2014

The BBC reports University of Copenhagen researchers may have located the source of seasonal affective disorder (SAD), commonly called the “winter blues.” After reviewing PET brain scans of those with SAD and comparing them to those without SAD symptoms, the researchers found significant summer-to-winter differences in serotonin transporter protein in those with SAD. This research suggests those with SAD have less available serotonin in the brain during winter months, leading to depressed mood. Further studies could determine if this effect is light-related in SAD patients, or if there is another cause.

Brain’s “Internal Compass” Found

December 22, 2014

University College London scientists, releasing data in the journal Current Biology, report that the strength of nerve signals in the entorhinal region of the brain could correlate to the strength of a person’s “sense of direction.” In a study, a group of subjects were asked to remember the placement of objects in a virtual room, then navigate toward those objects while their brain activity was monitored via an MRI. More studies of the entorhinal region of the brain could reveal why those with dementias lose their sense of direction and hopefully lead to ways to prevent this loss of function.

Older Minds Need Physical and Mental Activity

January 21, 2015

Edith Cowan University scientists in Australia present new findings on the combination of mental and physical activity on the health of older citizens in a new paper published in the journal Translational Psychiatry. The team’s study looked at 172 subjects aged 60 to 85, who had been split into four study groups—those who underwent weeks of consistent exercise, memory training, both, and neither. Exercise combined with memory training produced the only significant increases in verbal memory. This study, while isolated, does support the stance that both physical and mental exercise are necessary for the preservation of brain function in older citizens.
