Utah researchers link military sexual trauma to higher risk for veteran homelessness

Utah researchers link military sexual trauma to higher risk for veteran homelessness

The devastating consequences of sexual trauma in the military reported by 25 percent of female and 1 percent of male veterans who served in the U.S. armed forces don't end with psychological and physical trauma, but are associated with a much higher risk for homelessness, a study led by Utah researchers has found.

Scientists find interaction between amyloid and tau proteins that cause brain damage linked with AD

Scientists find interaction between amyloid and tau proteins that cause brain damage linked with AD

For years, neuroscientists have puzzled over how two abnormal proteins, called amyloid and tau, accumulate in the brain and damage it to cause Alzheimer's disease (AD). Which one is the driving force behind dementia? The answer: both of them, according to a new study by researchers at the Douglas Mental Health University Institute. [More]
New diagnostic approach may help physicians more efficiently screen for dementia

New diagnostic approach may help physicians more efficiently screen for dementia

A tiered diagnostic approach that incorporates clinical, imaging and laboratory data may help physicians more efficiently screen for neurodegenerative disorders such as dementia, according to the consensus of a multi-disciplinary panel of experts. [More]
Psilocybin administration reduces reaction to social rejection in associated brain areas

Psilocybin administration reduces reaction to social rejection in associated brain areas

Social ties are vital for mental and physical health. However, psychiatric patients in particular frequently encounter social exclusion and rejection. Furthermore, psychiatric patients often react more strongly to social rejection than healthy persons and this can have negative consequences for the development and treatment of psychiatric disorders.

Irvine neurobiologists find new way to change damaging course of Huntington disease

A study appearing April 14 in the journal Neuron suggests there may be a new way to change the damaging course of Huntington disease. [More]
Mouse model offers insight into molecular, neurological basis of stuttering

Mouse model offers insight into molecular, neurological basis of stuttering

Mice that vocalize in a repetitive, halting pattern similar to human stuttering may provide insight into a condition that has perplexed scientists for centuries, according to a new study by researchers at Washington University School of Medicine in St. Louis and the National Institutes of Health.

Heavy marijuana use may lead to lower dopamine release in the brain

Heavy marijuana use may lead to lower dopamine release in the brain

In a recent study, researchers found evidence of a compromised dopamine system in heavy users of marijuana. Lower dopamine release was found in the striatum - a region of the brain that is involved in working memory, impulsive behavior, and attention. Previous studies have shown that addiction to other drugs of abuse, such as cocaine and heroin, have similar effects on dopamine release, but such evidence for cannabis was missing until now. [More]

M10 peptide could help protect systemic sclerosis patients against fibrotic damage

M10 peptide could help protect systemic sclerosis patients against fibrotic damage

The results of preclinical studies by investigators at the Medical University of South Carolina (MUSC) reported in the April 2016 issue of Translational Research suggest that the M10 peptide could help protect against fibrotic damage in patients with systemic sclerosis, particularly in those who develop interstitial lung diseases (ILD), its deadliest complication.

PTSD patients carry long-term burden even with early clinical interventions

PTSD patients carry long-term burden even with early clinical interventions

The majority of people with post-traumatic stress disorder (PTSD) recover after early treatment -- but a substantial number still suffer for years after a traumatic event even with early clinical interventions, according to a study publishing online April 12, 2016 in The Journal of Clinical Psychiatry.

Depression combined with behavioral, metabolic symptoms increases risk of type 2 diabetes

Depression combined with behavioral, metabolic symptoms increases risk of type 2 diabetes

Depression may compound the risk of developing type 2 diabetes in people with such early warning signs of metabolic disease as obesity, high blood pressure and unhealthy cholesterol levels, according to researchers from McGill University, l'Université de Montréal, the Institut de recherches cliniques de Montréal and the University of Calgary.

Combination of genetic, environmental risk factors can trigger fatal eating disorder in humans

Combination of genetic, environmental risk factors can trigger fatal eating disorder in humans

In a new study, researchers from Columbia University Medical Center described a new mouse model featuring a combination of genetic and environmental risk factors that can trigger the compulsive restriction of food intake seen in patients with anorexia nervosa. The findings may help to identify new prevention and treatment strategies for the eating disorder in humans. [More]
Researchers link alcohol, cocaine misuse with future suicide attempt

Researchers link alcohol, cocaine misuse with future suicide attempt

In a general sense, medical studies support the popular intuition -- a staple of movies and literature -- that suicidal behavior and substance misuse are linked. But the relationship between the two is not so simple. A new study of hundreds of suicidal emergency department (ED) patients from around the U.S. found that the significance of the link varied with age, gender and race. Across the board, however, the use of cocaine and alcohol together was a red flag. [More]
Long-term medication use reduces risk of relapse and improves symptoms in BDD patients

Long-term medication use reduces risk of relapse and improves symptoms in BDD patients

People with Body Dysmorphic Disorder (BDD) fare better and are less likely to relapse when treated with medication on a long-term basis, according to researchers at Rhode Island Hospital and Massachusetts General Hospital. [More]
Monetary incentives aid smoking cessation among pregnant, post-partum women

Monetary incentives aid smoking cessation among pregnant, post-partum women

Smoking during pregnancy is the leading preventable cause of poor pregnancy outcomes. Studies further indicate that in-utero smoke exposure contributes to respiratory and cardiac illnesses later in life. [More]
Researchers identify blood-based biomarkers to accurately predict suicidal ideation in women

Researchers identify blood-based biomarkers to accurately predict suicidal ideation in women

Researchers have identified blood-based biomarkers and developed questionnaire-based apps that may help clinicians identify which of their female patients being treated for psychiatric disorders are at greatest risk of suicidal ideation or behavior. [More]
Chronic lack of sleep, irregular sleep-wake cycles may increase risk of Parkinson's disease

Chronic lack of sleep, irregular sleep-wake cycles may increase risk of Parkinson's disease

Chronic lack of sleep and irregular sleep-wake cycles may be risk factors of Parkinson's disease, new work by researchers at the Lewis Katz School of Medicine at Temple University suggests. In an animal model, the researchers show that disturbances in circadian rhythm that exist before Parkinson's onset dramatically worsen motor and learning deficits brought on by the disease. [More]

Mindfulness training can help manage painful cycles of thoughts in veterans with PTSD

Like an endlessly repeating video loop, horrible memories and thoughts can keep playing over and over in the minds of people with post-traumatic stress disorder. They intrude at the quietest moments, and don't seem to have an off switch. [More]
Remotely tracking patients' eye gaze could help identify children with ASD

Remotely tracking patients' eye gaze could help identify children with ASD

A study to be published in the April 2016 issue of the Journal of the American Academy of Child and Adolescent Psychiatry reports that eye tracking can differentiate children with autism spectrum disorder (ASD) from children without ASD but with other developmental problems (non-ASD). [More]
