Familial coaggregation of major psychiatric disorders and neurodevelopmental disorders among first-degree relatives of individuals with panic disorder.

BACKGROUND

This study aimed to assess the risk of major psychiatric and neurodevelopmental disorders in first degree relatives (FDRs) of individuals with panic disorder (PD), including PD, bipolar Disorder (BD), major depressive disorder (MDD), schizophrenia, obsessive-compulsive disorder (OCD), attention deficit hyperactivity disorder (ADHD), and autism spectrum disorder (ASD).

MATERIAL AND

METHODS

Between 2001 to 2010, we included 153,091 FDRs of individuals with PD and 1:4 matched controls based on age and sex from the Taiwan National Health Insurance Research Database. Poisson regression model with a robust error variance to estimate the relative.

RESULTS

After adjusting for demographics and psychiatric disorders, FDRs of individuals with PD had a higher risk of PD (reported as adjusted relative risk with 95% confidence interval: (ARR:2.74, 95%CI: 2.56 to 2.93), BD (ARR:1.24, 95%CI: 1.15 to 1.34), MDD (ARR: 1.46, 95%CI: 1.40 to 1.53), ADHD (ARR: 1.25, 95%CI: 1.18 to 1.32), and OCD (ARR:1.54, 95%CI:1.40 to 1.69) compared to their matched controls.

CONCLUSION

Our findings may aid in counselling and early awareness of major psychiatric and neurodevelopmental disorders. Future genetic and population studies are needed to investigate the underlying mechanisms and confirm our findings.
