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.
A study of 3,546 female twins found that genetics influence the rate of progression to problem drinking and alcohol dependence. Environmental factors played a significant role in the initiation of alcohol use, while genetic factors accounted for up to 47% of the influence on women's alcohol-related problems.
Social anxiety disorder is a chronic and pernicious condition that can lead to depression and substance abuse in adulthood. Research highlights the importance of understanding its neurobiological underpinnings, including increased amygdala activity and heritable temperamental traits.
Adolescent girls with ADHD are more likely to develop body-image dissatisfaction and binge-eating behaviors, according to a new study. The study found that these girls may be at risk for eating disorders, depression, and anxiety due to impulsive behaviors.
Researchers studied child/adolescent psychopathy, finding it resembles adult version but with areas of instability that could inform interventions. The special issue examines various aspects, including genetics, temperament, and parenting styles.
Risk factors for suicidal thoughts, plans, and attempts are consistent across countries, with mental disorders and female gender being key contributors. The study also found that impulse control disorders and substance use disorders increase the risk of acting on suicidal thoughts.
A new review integrates psychological and biological theories of autism, which may help medical professionals detect conditions such as Asperger's Disorder at an earlier stage. This approach could lead to better explanations for parents worried about their child's behaviour and potentially improve remediation.
A new UCLA study found that only half of children diagnosed with ADHD exhibit cognitive defects, challenging the common method for diagnosing the disorder. The research also suggested that medication is not always effective in treating ADHD, highlighting the need for alternative approaches to address long-term problems.
Adolescent girls who frequently eat with their families are less likely to engage in disordered eating behaviors. The study found that regular family meals reduced the risk of using diet pills or laxatives among teen girls. In contrast, adolescent boys did not show a similar protective effect.

A new study at the American College of Neuropsychopharmacology annual meeting found that psychotherapy, particularly cognitive therapy and cognitive behavioral therapy, significantly reduced PTSD symptoms when administered within a month after a traumatic event. The study suggests early intervention may prevent chronic PTSD development.
A new study found that individuals with alcohol dependence and conduct disorder have a high number of sex partners, increasing their risk for unintended pregnancies, infections, and reproductive health damage. Researchers also suggested that college campuses and healthcare staff play crucial roles in addressing this issue.
A randomized controlled trial found that combining fluoxetine with cognitive behavioral therapy improved depression scores in teens with co-occurring depression and substance abuse disorders. The treatment was as effective as the antidepressant alone in treating depression among teens without substance abuse problems.

A review of 32 cases finds violent behavior most frequently appears after direct provocation or close proximity, affecting 81% of sleep terror patients and 100% of confusional arousal patients. Sleepwalking episodes often follow minor provocation, with men displaying more aggressive behavior.
Researchers at Cold Spring Harbor Laboratory propose a new model for understanding how autism is acquired, suggesting that spontaneous germ-line mutation is a significant cause. This mutation can be carried by women without severe symptoms and passed on to their children, increasing the risk of sons developing autism.
A study of twins has connected genetic factors to the link between smoking addiction and major depression. The research found a shared gene associated with conduct disorder, which increases the risk of nicotine dependence and major depression, also leading to impulsivity and other drug addictions.

A new study finds that children whose mothers were exposed to second-hand smoke during pregnancy exhibit more symptoms of ADHD and conduct disorder compared to those with no prenatal exposure. The research suggests that nicotine affects brain development during pregnancy, leading to behavioral problems in children.
A recent literature review and formal classification of sleep-related disorders associated with abnormal sexual behaviors and experiences have been published. These disorders, referred to as 'sleepsex' or 'sexsomnia', can cause disturbing and embarrassing symptoms, and may lead to delays in seeking help due to fear of judgment.
A study found that adults who were close to the 9/11 disaster had increased amygdala activity in response to emotional stimuli several years later. The results suggest long-term neurobiological correlates of trauma exposure and potential vulnerability to mental health disorders.
A study by UCLA researchers found that children with autism exhibit reduced activity in the ventrolateral prefrontal cortex, a region responsible for evaluating emotions and context. This impairment affects their ability to process visual cues like eye gaze and facial expressions.
Children with a family history of autism exhibit impaired social referencing, seeking emotional cues less frequently and failing to respond consistently to adult reactions. Brain activity measurements also show differences in neural response to emotionally tagged objects.
A study published in The Journal of Pediatrics found that delayed treatment of childhood-onset bipolar disorder results in longer periods of depression, more episodes, and increased substance abuse risk.

The study reveals behaviors similar to humans with bipolar disorder, including hyperactivity and euphoria, which are restored by lithium treatment.
A study found no difference in the relapse rate of people with compulsive-buying disorder when taking escitalopram compared to those on a placebo, contradicting previous research findings. The results may be due to differences in biological roots among individuals with the disorder.
Researchers at the University of Iowa have developed genetic tests that may help identify individuals at risk of substance abuse and behavioral disorders. The study found differences in gene expression between people with a history of smoking and those without, suggesting potential blood tests for identifying risk factors.
Patients with Parkinson's disease who develop the condition at a younger age and have a history of alcohol abuse are more likely to experience pathological gambling as a side effect of dopamine agonist medications. Behavioral characteristics such as impulsivity and risk-taking behavior may also play a role in this increased risk.
A Mayo Clinic study found a link between dopamine agonist medications and compulsive gambling in RLS patients. The medication-induced behavior worsened with increasing doses, but was reversible when the dose was reduced or alternative medication was used.
The incidence of autism and two other childhood neuropsychiatric disorders increased significantly among Danish children between 1990 and 2004. This trend suggests a broader pattern in childhood mental illness, with the exception of obsessive-compulsive disorder.
Researchers focus on preventing psychopathological symptoms in pre-school children, with 99% of unaffected children not developing disorders later in life. The study aims to improve prevention and detection of emotional and behavioral disorders among this critical age group.

The research also shows that 33% of students with Attention Deficit Hyperactivity Disorder have never received treatment.
A recent study found that autism is a global disorder affecting how the brain processes information, particularly when it becomes complicated. The study discovered that individuals with autism perform well in basic functioning tasks but struggle with complex tasks involving sensory perception, movement, and memory.
Research on over 14,000 hospital patients and 38,000 controls found that workplace violence increases the risk of depression by 45-48% in both men and women. The magnitude of risk is directly proportional to the amount of violence experienced at work.
