Different brain structures in females lead to more severe cognitive deficits after concussion than males      (via sciencedaily.com)     Original source 

Important brain structures that are key for signaling in the brain are narrower and less dense in females, and more likely to be damaged by brain injuries, such as concussion. Long-term cognitive deficits occur when the signals between brain structures weaken due to the injury. The structural differences in male and female brains might explain why females are more prone to concussions and experience longer recovery from the injury than their male counterparts.

Alzheimer's disease without symptoms: How is that possible?      (via sciencedaily.com)     Original source 

Everyone experiences aging in their own way, and factors such as genetics, lifestyle and environment play a role in this process. Some individuals reach the age of 90 or even 100 in good health, without medications or brain disease. But how do these individuals maintain their health as they age?

An astrocytic pH regulator that can repair the blood-brain barrier and reverse brain damage caused by ischemic stroke      (via sciencedaily.com)     Original source 

A recent study has found that an ion transporter protein that regulates the pH of specific brain cells can repair the blood-brain barrier and restore normal brain function after ischemic stroke. The study has revealed novel and specific therapeutic targets for ischemic stroke and related brain conditions for which no targeted treatments exist currently.

Some brain cells age faster and are more prevalent in Alzheimer's      (via sciencedaily.com)     Original source 

Engineers have discovered that some brain cells age more rapidly than others, and they are disproportionately abundant in individuals afflicted with Alzheimer's disease. Additionally, researchers observed male-female-specific differences in the aging process of certain brain cells, with the female cortex exhibiting a higher ratio of 'old' oligodendrocytes to 'old' neurons compared to the male cortex. The discoveries were made possible by a new technique called MUSIC (multinucleic acid interaction mapping in single cells), which allows researchers to peek inside individual brain cells and map out interactions between chromatin--which is the tightly coiled form of DNA -- and RNA.

Study reveals patients with brain injuries who died after withdrawal of life support may have recovered      (via sciencedaily.com)     Original source 

Analysis of 1,392 patients with traumatic brain injuries (TBIs) found that some patients for whom life support was withdrawn may have survived and recovered some level of independence a few months after injury. Families are often asked to make decision to withdraw life support within 72 hours of a brain injury, and the new study suggests delaying decisions may be beneficial for some patients.

Study shows heightened sensitivity to PTSD in autism      (via sciencedaily.com)     Original source 

A new study shows that a mild stress is enough to trigger post-traumatic stress disorder (PTSD) in mouse models of autism spectrum disorder (ASD). Researchers demonstrated that the two disorders share a reciprocal relationship, identifying a predisposition to PTSD in ASD, and discovering that core autism traits are worsened when traumatic memories are formed.

'Wraparound' implants represent new approach to treating spinal cord injuries      (via sciencedaily.com)     Original source 

A tiny, flexible electronic device that wraps around the spinal cord could represent a new approach to the treatment of spinal injuries, which can cause profound disability and paralysis. A team of engineers, neuroscientists and surgeons developed the devices and used them to record the nerve signals going back and forth between the brain and the spinal cord. Unlike current approaches, the new devices can record 360-degree information, giving a complete picture of spinal cord activity.

A new mother's immune status varies with her feeding strategy      (via sciencedaily.com)     Original source 

In one of the first studies of its kind, UC Santa Barbara researchers have found that the immune status of postpartum mothers shifts with how she feeds her baby. Certain inflammatory proteins -- substances that are secreted as part of an immune response -- peak at different times of day, correlating with whether the mothers breastfeed, pump or formula-feed their babies.
