A personal survey of patients with atrial fibrillatio, one of the most important causes of irregular heartbeats, has found that the majority of triggers for the condition are easily modifiable lifestyle choices, including alcohol, caffeine, exercise and lack of sleep.
For the first time, scientists discovered how neuroactive steroids naturally found in the brain and bloodstream inhibit the activity of a specific kind of protein called Toll-like receptors (TLR4), which have been known to play a role in inflammation in many organs, including the brain.
Adolescent cannabis use has been linked to an increased risk of depression and suicidal behavior in young adulthood, according to the first meta-analysis by a team of scientists at the Research Institute of the McGill University Health Centre and McGill University, in collaboration with the University of Oxford and Rutgers University-Camden, which is published in the journal JAMA Psychiatry today.
Four- to six-year-old children who express suicidal thoughts and behaviors have a better understanding of what it means to die than the majority of their peers, reports a study recently published in the Journal of the American Academy of Child and Adolescent Psychiatry.
Researchers in Germany have discovered why sleep can sometimes be the best medicine. Sleep improves the potential ability of some of the body's immune cells to attach to their targets, according to a new study that will be published Feb. 12 in the Journal of Experimental Medicine. The study, led by researchers at the University of Tübingen, helps explain how sleep can fight off an infection, whereas other conditions, such as chronic stress, can make the body more susceptible to illness.
Unlike postpartum readmissions for medical or obstetric complications, psychiatric readmissions were least likely to occur in the first 10 days after discharge. Instead, psychiatric readmissions take place later in the postpartum period.
Used in the right way, smartphones may not be as isolating as some would think. A new Carnegie Mellon University study suggests smartphone-based mindfulness training may help individuals feel less lonely and motivate them to interact with more people. The researchers also found acceptance skills training to be a critical active ingredient for improving these social functioning outcomes.
Researchers examined the prevalence and impact of six common symptoms (pain, fatigue, depression, anxiety, breathing difficulty, sleep problems) and found that nearly half of adults ages 65 and older have two or more of these symptoms and one-fourth have three or more. But often clinicians miss these symptoms, and the more serious health issues they portend because patients only talk about one of these symptoms during a visit.
A research team from Arizona State University, DePaul University and the University of Southern California analyzed how effective evidence-based mental health intervention programs were for ethnic minority youth in the United States. Four treatment programs met the criteria of 'well-established.' These treatments addressed substance abuse, disruptive behavior and anxiety in Hispanic/Latino and African-American youth. Native-American and Asian-American youth were underrepresented or absent from research studies on mental health intervention programs.
Chronic rhinosinusitis is a common condition marked by sinus inflammation that can make breathing difficult and cause face pain or tenderness. The condition affects quality of life but whether it contributes to depression and anxiety in patients is unclear. This study of about 49,000 people in a South Korean insurance database examined the risk of depression and anxiety in chronic rhinosinusitis and depending on the type of chronic rhinosinusitis (with or without nasal polyps).
