The research, led by Boston University School of Medicine, found that individuals with impulsive tendencies were more likely to engage in binge eating behavior.
Childhood obesity is linked to mental health issues and decreased academic performance. Dr. Kaliebe's three rules aim to promote physical and mental well-being through healthy eating, regular movement, and reducing sensory overload.
A new study published in Biological Psychiatry found that deep brain stimulation increases striatal dopamine release in patients with OCD, potentially aiding their control over compulsive behaviors. The treatment's effectiveness may relate to its ability to compensate for underlying dopamine dysfunction.
The study found that copy number variant (CNV) genetic testing can help diagnose and treat autism more effectively. CNV testing uncovered dozens of cases where autism-linked gene changes were associated with additional health risks warranting medical attention.
Two new studies published in Biological Psychiatry suggest that obsessive-compulsive disorder (OCD) may be characterized by a tendency to form compulsive habits, rather than irrational beliefs. Researchers found that individuals with OCD displayed impairments in goal-directed decision making and avoidance habits.
A small study published in BMJ Open suggests that men with eating disorders are underdiagnosed, undertreated, and understudied. The perception that eating disorders are a women's problem delays men from seeking help, with some experiencing significant distress and suicidal thoughts.
A study in the Journal of Developmental & Behavioral Pediatrics found a strong association between teen indoor tanning and unhealthy weight control behaviors. Females who used indoor tanning were more likely to report fasting, vomiting, or taking laxatives to lose weight.
Researchers found that repeated hUCB MNC injections produced greater neuroprotection in mice modeled with MPS III B, preserving hippocampal structure and reducing microglial activation. The treatment also showed promise in modulating anxiety and inflammation.
A randomized trial found that integrating brief behavioral and mental health programs in pediatric practices improved access to care, participation, and treatment completion. Pediatricians who received training reported increased confidence and efficacy in treating ADHD.

Participants with gender variance also experienced elevated anxiety and depression symptoms, but to a lesser extent among...
A major new study found that pre-enlistment mental disorders are a significant risk factor for suicidal ideation among US soldiers. The study, which surveyed over 975,000 Army personnel, reveals that nearly 60% of soldier suicide attempts can be traced to these conditions, with the vast majority developing them before enlistment.
A study of 64,322 children found that mothers who used acetaminophen during pregnancy were at higher risk for their children developing ADHD-like behaviors and hyperkinetic disorders. The use of acetaminophen in multiple trimesters increased the risk further.
