Question 1

What are anxiety disorders and what causes them?

Accepted Answer

Anxiety disorders are a group of conditions unified by shared dysfunction in the amygdala-BNST-prefrontal fear circuitry, with heritability of 20-60% across subtypes (51 risk loci identified in a 2024 GWAS of 1.2 million participants). They follow a predictable developmental sequence from separation anxiety (mean onset ~10.6 years) through GAD (mean onset ~34.9 years), persist into adulthood in the majority of cases, and respond to SSRIs (aggregate SMD 0.56 vs placebo; Gosmann et al., 2021) and CBT (NNT ~3 in children). They are the most prevalent class of psychiatric disorders worldwide, yet only 9.8% of affected individuals receive adequate treatment.
