A study published in JAMA Psychiatry found that rural African-American women had lower rates of major depressive disorder (MDD) and mood disorder compared to their urban counterparts. In contrast, rural non-Hispanic white women had higher rates of MDD and mood disorder. The findings suggest the need for further research into the correl...
PTSD survivors often experience sexual dysfunction due to biological and cognitive processes related to traumatic stress. The condition disrupts trust, safety, and emotional connection, associating arousal with threat.
