The study, which examined 46 inpatients with traumatic brain injuries, suggests that losing consciousness may be a protective factor against developing PTSD.
The U-M study found lower rates of major depression, panic disorder, social phobia, and generalized anxiety disorder among African Americans, especially men. Afro-Caribbean women had higher rates of mental disorders compared to their counterparts, likely due to structural inequalities in economic and social resources.
A study found that individuals with panic disorder have reduced expression of the 5-HT1A receptor protein, which regulates serotonin synthesis and release. This reduction is associated with decreased function in brain areas critical for anxiety regulation.
