A study from Université de Montréal and Douglas Mental Health University Institute found that 10-15% of women experience maladaptive eating behaviors, which can lead to binge eating, bulimia, and excessive exercise. The study also revealed a link between problematic eating habits and self-rated health.
Researchers found that medications used to treat substance addictions can also help suppress the urge to gamble, particularly for those driven by urge. Medications targeting the brain opioid system or catechol-O-methyl-transferase (COMT) enzyme showed positive outcomes in treating pathological gambling disorder.
Researchers found that a mutation in a dopamine receptor causes flies to exhibit exaggerated hyperactivity and hypersensitivity to air puffs. The study suggests a link between dopamine regulation and ADHD symptoms, as well as learning disabilities. Flies without the mutation learn to associate an odor with an electric shock quickly.

A new study suggests that maternal smoking during pregnancy may increase newborns' distress levels, potentially related to reduced monoamine oxidase A (MAO-A) activity. This reduction in MAO-A activity can lead to dysregulation of brain neurotransmission, creating a potential vulnerability to behavioral disorders later in life.
Researchers found that devout Christians and nonbelievers use the same brain regions to judge the truth of religious and nonreligious propositions. The study also found increased activity in the ventromedial prefrontal cortex (VMPFC) when contrasting belief and disbelief, regardless of content.

Fetal alcohol exposure can disrupt thyroid hormone levels, leading to neurodevelopmental disorders such as emotional behavioral disorders and deficits in learning, memory, and speech.
A new study published in Archives of General Psychiatry found that the antidepressant citalopram did not reduce repetitive behaviors in children and teens with autism spectrum disorders. The medication, an SSRI, was tested in a randomized controlled trial involving 149 children with moderate to severe repetitive behavior.
Hyperactivity disorder as understood today is a relatively recent phenomenon, says researcher Matthew Smith. He argues that historical figures like Mozart were not necessarily considered hyperactive due to societal context.

The study also notes the potential for 'child-to-parent effects' and emphasizes the need for further international research.
A new study finds that black girls are 50% more likely to exhibit bulimic behavior, including binging and purging, compared to white girls. The study also reveals that girls from low-income families are significantly more likely to experience bulimia than their wealthier peers.
Researchers discovered an abnormality in the brains of adolescent boys with attention deficit hyperactivity disorder, particularly in the anterior cingulate cortex. This region normally activates when a reward stops, but in boys with ADHD, it fails to do so, leading to continued activation and impulsive behavior.

The study found that nearly half of patients with this condition develop a neurodegenerative disease within 12 years of diagnosis.
A recent study used Diffusion Tensor Imaging (DTI) to assess white-matter microstructure in youth with and without histories of heavy prenatal alcohol exposure. The findings show that alcohol can damage the microstructural integrity of fetal cerebral white matter, particularly in the frontal and occipital lobes, which are relevant for ...

Researchers used Palm Pilots as electronic diaries to analyze mood variability in BPD patients, finding significant instability in positive and negative moods. The devices helped bridge the communication gap between therapists and patients.
Researchers have uncovered structural features of the brain that may contribute to the development of ADHD. The study used a new analysis tool to examine shape differences in the brains of children with ADHD and found significant abnormalities in boys, but not girls.
Researchers found that high doses of cortisone can prevent negative consequences of stress exposure, including increased startle response and behavioral freezing. This finding suggests a possible treatment option for post-traumatic stress disorder (PTSD) in its acute phase.
Researchers have identified three new candidate genes for schizophrenia that may contribute to a better understanding of the disease. These genes are associated with brain function and are present in only 1% of schizophrenia patients, suggesting they play a significant role in its development.
Researchers found a correlation between motor task performance and myelin integrity, peaking in middle age before declining. Myelin breakdown may underlie cognitive decline and physical skills erosion, but therapeutic interventions could slow the process.
A new study finds that non-daily smokers are 16 times more likely to be hazardous drinkers than non-smokers, and five times more likely to meet criteria for an AUD. The study suggests that casual smoking may promote hazardous drinking behavior.
Researchers found that participants primed with action words chose active tasks, but the stimulus triggered diverse array of tasks not normally seen together. This suggests a need for more specific cues on how to be active.

Research suggests a strong association between depression, sleep deprivation, and suicidal behavior in children and adolescents. Sleep complaints during depressive episodes can be an indicator of suicidal behavior, particularly in pediatric bipolar disorder patients.
A team of scientists found that intrinsic disorder in relaxor crystals leads to their extreme sensitivity to mechanical pressure or voltage. This property makes them useful for applications such as medical ultrasound imaging, loudspeakers, sonar, and computer hard drives. The research was published in Nature Materials.
Researchers identified associations between genetic variants in genes controlling affiliative behaviors and social deficits in autistic children. The strongest findings implicate the prolactin gene, oxytocin receptor gene, and prolactin receptor gene.
A recent study published in the American Journal of Psychiatry estimates that major mental disorders result in significant losses of human productivity, with individuals with serious mental illness earning approximately $22,545 per year. The total economic burden is attributed to lost earnings and increased likelihood of unemployment.
A multi-site consortium is gathering genetic and behavioral information about cases with only one family member having autism. The Simons Simplex Collection will create a database of genetic and behavioral information, leading to the discovery of new genetic factors that increase the risk of autism.
A study published in Archives of Pediatrics and Adolescent Medicine found that US teens adopted as infants may be at a greater risk for emotional and behavioral problems. Adoptees were more likely to have contact with a mental health professional and experience disruptive behavior disorders compared to non-adopted adolescents.
A Yale University study found that individuals who used a computer-assisted training program in addition to traditional counseling stayed abstinent significantly longer. The subjects had fewer positive drug tests at the conclusion of the study.
A new study published in PLOS ONE reveals that mice and humans exhibit similar behavioral patterns, with no differences in statistics between resting periods and activity durations. This discovery has implications for the development of new treatments for depression and challenges current models of human-specific disorders.
