What the age of your brain says about you
A study just published in Molecular Psychiatry introduces a clinically relevant neuroimaging aging biomarker and demonstrates that combining distinct measures of biological aging further helps to determine risk of age-related deterioration and death. Such biomarkers could potentially identify those at risk of age-associated health problems years before symptoms appear, and be used as outcome measures in trials of therapeutics aimed at delaying the onset of age-related disease.

Could regulating the circadian rythm help people regain consciousness?
A study published today in the journal Neurology is the first to report an association between circadian variations in body temperature and arousal in brain-injured patients.

Researchers discover birth-and-death life cycle of neurons in the adult mouse gut
Using a mouse model, Johns Hopkins researchers finds proof that every day the gut loses and regenerates about 5% of its nerve cells, and that over the course of a few weeks, the whole enteric nerve system turns over. The study findings are published in Proceedings of the National Academy of Sciences.

Surprising brain change appears to drive alcohol dependence
A new study could help researchers develop personalized treatments for alcoholism and alcohol use disorder. The research reveals that when alcohol-dependent versus nondependent rats were given alcohol, both groups showed increased activity in the central amygdala (CeA) -- but that this activity was due to 2 completely different brain signaling pathways.

Cognitive decline after surgery tied to brain’s own immune cells
A new study in mice by UC San Francisco researchers suggests that brain inflammation and cognitive decline following surgery are triggered by the brain's own microglia. The study is published in JCI Insight, an online, open-access companion publication to the Journal of Clinical Investigation.

Cost of neurologic disease in United States approaching $800 billion a year
A study published in the Annals of Neurology looks at 9 the most prevalent and costly diagnosed neurologic disorders and finds that research investment is critical to prevent the destabilizing impact of these enormous rising costs.

Never before seen images of early stage Alzheimer disease
Researchers at Lund University have used the MAX IV synchrotron to produce images that predate the formation of of beta-amyloid plaques. They reveal that beta-amyloid is not a single peptide, but instead a tetramer. This suggests that instead of attempting to eliminate beta-amyloid, it should be stabilized.

Researchers find neurologic link between religious experiences and epilepsy
Researchers from the University of Missouri found a neurologic relationship exists between religiosity--a disposition for spiritual experience and religious activity--and epilepsy. This finding sheds light on the connection between religion and neuropsychological processes within the human brain.

New analysis reveals 24 compounds that can help reduce impact of harmful proteins in the brain
A study by Indiana University researchers has identified 24 compounds--including caffeine--with the potential to boost an enzyme in the brain--NMNAT2--shown to protect against dementia. The new study appears today in the journal Scientific Reports.

Zika may cause miscarriages, thin brain tissue in babies carried to term
Using unique mouse model, Johns Hopkins researchers believe they can develop treatment or vaccine targets in order to fight the virus. The study findings were published today in Nature Communications.
