A study of more than 83,000 questionnaires by women ages 50-79, found more than 25% developed irregular heart rhythms, known as atrial fibrillation, which may increase their risk for stroke and heart failure. http://dlvr.it/SvR8KY

Researchers have succeeded in transforming brain signals into audible speech. By decoding signals from the brain through a combination of implants and AI, they were able to predict the words people wanted to say with an accuracy of 92 to 100%. http://dlvr.it/SvPcB3

A new study shows that people suffering from hospital-treated depression may have a high risk of developing conditions such as substance abuse, bipolar disorder, schizophrenia and anxiety -- depending on their genetic predisposition to the individual disorder. http://dlvr.it/SvMBh7

Sleep is a critical part of a child's overall health, but it can also be an important factor in the way they behave. According to a new study, getting enough sleep can help children combat the effects of stressful environments. http://dlvr.it/SvLyW1

In the new study, the team used the model to demonstrate that as Alzheimer's pathology accumulates in the brain, specific types of immune cells called CT8+ T Cells surge into the brain and amplify the destruction caused by neuroinflammation. http://dlvr.it/SvBQMT

Researchers make progress in developing a digital biomarker that detects early signs of Alzheimer's disease in brainwave patterns using a simple 'wearable' headband at night. http://dlvr.it/Sv6j58

Researchers have developed a brain-computer interface (BCI) that has enabled a woman with severe paralysis from a brainstem stroke to speak through a digital avatar. http://dlvr.it/Sv545X

Many researchers believe that the neurodegenerative disorder gets started in the gut. Research now suggests that an autoimmune reaction may be driving those early events. http://dlvr.it/Sv2T0P

People who have recovered from a major depressive episode, when compared with individuals who have never experienced one, tend to spend more time processing negative information and less time processing positive information, putting them at risk for a relapse, according to new research. http://dlvr.it/Sv2DNR

A new study has demonstrated the ability for gene therapy to repair neural connections for those with the rare genetic brain disorder known as Hurler syndrome. http://dlvr.it/Sv0GSS

Amyotrophic lateral sclerosis (ALS) is a widespread neurodegenerative disease caused by the loss of neurons that control movement. Although abnormal accumulation of proteins called TDP-43 accompanies ALS, its role in disease progression is not well understood. Recently, using novel mouse models of ALS, researchers have identified the neurological spreading patterns through which TDP-43 perpetuates the degeneration of the movement-related neural circuitry. http://dlvr.it/StzBJk

Obesity leads to altered energy metabolism and reduced insulin sensitivity of cells. The so-called 'anti-obesity drugs' are increasingly used to treat obesity and have caused tremendous interest, especially in the USA. Researchers have now shown in people with obesity that reduced insulin sensitivity affects learning of sensory associations. A single dose of the anti-obesity drug liraglutide was able to normalize these changes and restore the underlying brain circuit function. http://dlvr.it/StxTbk

Somatostatin, a signaling molecule produced by many inhibitory neurons in the brain, broadly dampens communication among a variety of cell types in the prefrontal cortex and promotes exploratory and risk-taking-like behavior in mice. http://dlvr.it/Stw0pX

The largest ever study of the genetics of the brain -- encompassing some 36,000 brain scans -- has identified more than 4,000 genetic variants linked to brain structure. http://dlvr.it/SttgJ7

When choosing their behavior in socially difficult situations, anxious people use a less suitable section of the forebrain than people who are not anxious. http://dlvr.it/Stt3Yg

Researchers have found an injection of a specific blood factor can replicate the benefits of exercise in the brain. They've discovered that platelets secrete a protein, exerkine CXCL4/Platelet factor 4 or PF4, that rejuvenates neurons in aged mice in a similar way to physical exercise. This protein, which is released from platelets after exercise, results in regenerative and cognitive improvements when injected into aged mice. http://dlvr.it/StsTMs

Can you recognize an old friend, but forget what you had for breakfast yesterday? Our brains constantly rearrange their circuitry to retain information, but the molecular basis behind this process isn't well understood. New research suggests that complex sugars called glycosaminoglycans might play a major role in the 'plasticity' of the brains of mice and could be used to repair neural connections after injury. http://dlvr.it/Stpr35

Developing a framework for future research requires a comprehensive approach based on diagnosis, stage of recovery, and domain. http://dlvr.it/Stm53c

A new digital headset designed to measure alterations in brain function could change decisions about how quickly an athlete is ready to return to play after a concussion. In an evaluation of the device, researchers found it revealed brain changes even in athletes whose concussion symptoms had gone away, suggesting they could be playing too soon. http://dlvr.it/Stl1g0

A first-in-human trial of deep brain stimulation (DBS) for post-stroke rehabilitation patients has shown that using DBS to target the dentate nucleus -- which regulates fine-control of voluntary movements, cognition, language, and sensory functions in the brain -- is safe and feasible. http://dlvr.it/StfH1H
