Easy at-home assessment of teeth grinding in sleep
An easy-to-use electrode set can assess sleep bruxism severity as well as a conventional polysomnography, a new study shows.

Health care intervention: Treating high-need, high-cost patients
Patients with complex needs — serious mental and physical health problems and substance use disorders — flock to emergency rooms costing the health care system billions every year. A new study suggests a nontraditional approach to these patients can significantly improve their daily functioning and health outcomes.
Read moreBARseq builds a better brain map
A brain mapping technique called BARseq is capable of mapping thousands of neurons in a single mouse, at single neuron resolution, while also detailing which neuron expresses what genes. It could be a game-changer for how neuroscientists look at brains.
Read moreTreatment of metabolic dysfunction could be a potential therapy for Alzheimer's disease
A team of researchers has found evidence that metabolic dysfunction is a primary cause of Alzheimer's disease.
Read moreScientists develop test for uncommon brain diseases
Scientists have developed an ultrasensitive new test to detect abnormal forms of the protein tau associated with uncommon types of neurodegenerative diseases called tauopathies. This advance gives them hope of using cerebrospinal fluid, or CSF — an accessible patient sample — to diagnose these and perhaps other, more common neurological diseases, such as Alzheimer's disease.
Read moreNew insights into biological underpinnings of schizophrenia
Researchers have implicated 10 new genes in the development of schizophrenia using a method called whole exome sequencing, the analysis of the portion of DNA that codes for proteins. A global consortium of schizophrenia research teams incorporated genetic data from over 125,000 people to gain deeper insights into the genetic underpinnings of schizophrenia.
Read moreProtein misfolding as a risk marker for Alzheimer's disease
In symptom-free individuals, the detection of misfolded amyloid-beta protein in the blood indicated a considerably higher risk of Alzheimer's disease — up to 14 years before a clinical diagnosis was made. Amyloid-beta folding proved to be superior to other risk markers evaluated.
Read moreHope is a key factor in recovering from anxiety disorders
A psychologist is reporting that hope increases in therapy and is a trait that predicts resilience and recovery from anxiety disorders, an important mechanism for therapists to restore in patients to move them forward toward recovery.
Read moreWidely available drug reduces head injury deaths
A low cost and widely available drug could reduce deaths in traumatic brain injury patients by as much as 20%, depending on the severity of injury, according to a major study. The researchers say that tranexamic acid (TXA), a drug that prevents bleeding into the brain by inhibiting blood clot breakdown, has the potential to save hundreds of thousands of lives.
Read moreHappy, angry or neutral expressions? Eyes react just as fast
Scientists have investigated how our eyes and brain react when we see emotionally charged or neutral faces. She combined eye-tracking and electroencephalography (EEG). The result: reflex-like eye movements are independent of the expression a face shows; our attention is drawn to them just as fast.
