양극성장애 부모의 자녀에서 정신 질환

Abstract

Objectives Information on the specificity of associations between parents with bipolar disorder (BPD) and risk of psychopathology in their offspring is limited. The aim of this study was to examine the prevalence of mental disorders in the offspring of individuals with BPD in South Korea.

Methods The sample consisted of 100 child and adolescent offspring (aged 6.0-18.9 years) from 65 nuclear families having at least one parent with BPD. Probands, offspring, and biological co-parents were interviewed using a semi-structured diagnostic interview and the offspring were evaluated using the Korean version of the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL).

Results Sixty one of the 100 participants met the criteria for at least one mental disorder. Of these, 35 participants had a mood disorder, 35 had an anxiety disorder, and 29 had attention-deficit hyperactivity disorder (ADHD). Thirty nine of the offspring had no psychiatric diagnosis. Of the 35 with a mood disorder, 16 (45.7%) had comorbid ADHD and 18 (51.4%) had comorbid anxiety disorders.

Conclusion Offspring of parents with BPD are at high risk for mental disorders. These findings further support the heredity of BPD and indicate the need for early identification and treatment.
