The investigation also revealed that children with atypically high depression and anxiety levels are more likely to have mothers with a history of depression.
A study published in BMC Psychiatry found that lesbian, gay, and bisexual individuals are twice as likely to receive mental health treatment as heterosexuals. The researchers attribute this disparity to higher exposure to discrimination and violence, as well as societal pathologizing of homosexuality.
A recent study published in Biological Psychiatry found that hormone levels play a crucial role in stress resilience among military combat divers. Soldiers with higher dehydroepiandrosterone (DHEA) levels performed better during stressful underwater navigation exercises.
Research suggests preschool depression is a continuous, chronic condition that increases the likelihood of subsequent depression and psychiatric disorders. Early intervention during the preschool period may be crucial in addressing childhood major depressive disorder.
Researchers have found similarities between brain activity during lucid dreaming and psychosis, suggesting dream therapy could be useful in treating psychiatric conditions. Dissociation, a state of losing conscious control, is common in both lucid dreaming and certain psychiatric disorders.
A new definition of major depressive disorder (MDD) suggests that only mood and cognitive symptoms are included, excluding somatic criteria. This revised definition was found to be highly concordant with the current version in a large sample of psychiatric outpatients, offering benefits such as reduced time needed for assessment and sh...
A 20-year study found that impulsive boys with inadequate supervision and poor families are more likely to commit criminal acts. The study also revealed that the juvenile justice system's help increased the risk of early adulthood crime, especially among those with similar histories without judicial involvement.
