The Influence of Chronic Stress on the Development of Psychiatric Conditions

摘要

A 20-year-old woman with a history of bipolar disorder (BD), posttraumatic stress disorder (PTSD), and borderline personality disorder (BPD) presented to the emergency department with suicidal ideation. This report compares her clinical course with that of her twin brother, who also had received a BD diagnosis but grew up in a less stressful environment than his sister. It also describes the possible genetic and environmental etiologic factors associated with BD, PTSD, BPD, and other psychiatric conditions. Chronic stress is strongly associated with the development of these conditions; pathologic processes involving the effect of stress hormones and neurotransmitters on the brain and central nervous system are described, along with pharmacologic and nonpharmacologic approaches to reducing chronic stress in persons with BD and other psychological disorders.
