Kaplan argue that the criteria for establishing a connection between strep and behavioral disorders are too vague, citing a lack of evidence from large, carefully controlled studies.
Researchers at UCLA have made a groundbreaking discovery about the biology of fear, finding that yohimbine accelerates the process of overcoming conditioned fear in mice. By enhancing the effects of natural adrenaline release, yohimbine allows mice to overcome their fear four times faster than those treated with vehicle or propanolol.

A study published in The Lancet found that single-session psychological debriefing after traumatic events is ineffective and may even do more harm than good. The research suggests that formal therapy like critical incident stress debriefing can prevent people from seeking natural family or social support systems.
A study by Larry W. Hawk Jr., Ph.D., found that paid college students showed decreased blink size and strength in response to loud noises, indicating increased attentiveness. While payment motivated better task performance, it didn't lead to significant differences in overall results.

A study conducted by Ohio State University found that 20% of women and 5.8% of men among the student-athletes reported behaviors associated with eating disorders, including binge-eating and purging. The survey also revealed that 38% of athletes thought certain body parts were too fat, with a higher prevalence among female athletes.

A new study found that risperidone, an antipsychotic agent, was effective in reducing irritability and behavioral problems in children with severe autism. The trial involved 101 children between ages 5 and 17, showing a significant positive response to treatment, with 69% experiencing marked improvement.
The article highlights the significant impact of behavioral factors on various diseases, including coronary heart disease, diabetes, obesity, and asthma. Research shows that negative emotions can lower immunity, while stress and depression can provoke the release of hormones that affect immune function.
A study found that nearly 16% of alcoholics had attempted suicide, and first-degree relatives of those who attempted suicide were more likely to have made attempts as well. The risk factors included a history of severe alcohol dependence and psychiatric disorders.
Researchers at Stanford Medicine have identified a medical condition causing violent 'sleep sex' behaviors, characterized by loud moaning and sexual assault during sleep. The disorder can be treated with standard sleep disorder treatments, including therapy and medication.
A recent study found that heightened depressive symptoms, emotional eating, and low self-esteem can predict binge-eating disorders in teenage girls. The research also revealed that low peer support increases the risk of binge eating, while parental support has no effect on this issue.
A study of 820 female college students found depression and alexithymia more strongly associated with disordered eating than childhood abuse and neglect. Researchers suggest interventions addressing adaptive coping mechanisms for depression may help individuals with disordered eating behaviors.
Researchers studied brain lesions in children with tuberous sclerosis complex and found autism results from complex brain events, not single source. Biochemical abnormalities in outer layer of the brain impacted communication skills, while subcortical changes led to stereotypical behaviors.

Researchers found that an early AFD is associated with increased rates of substance abuse, mental health problems, and educational underachievement. Early drinking is also linked to genetic risk for disinhibitory behaviors, suggesting it may be a symptom rather than a cause of alcoholism.
A recent study found that adolescents with both alcohol and antisocial problems exhibit an increase in serotonin function, contradicting previous research on Type II alcoholism. This suggests that serotonin dysregulation may be key to high-risk behaviors, rather than low or high levels of the neurotransmitter.
