Eating disorders are 40–60% heritable, shaped by genes and environment together. A landmark anorexia GWAS revealed both psychiatric and metabolic roots, implicating genes like HTR2A and BDNF. This article explains the genetics, the metabo-psychiatric model, and evidence-based, compassionate treatment context.

Stress resilience is partly genetic. Named variants in COMT (Val158Met), FKBP5, and BDNF shape how intensely your brain and cortisol system react to pressure and how quickly they recover. Learn the biology of stress coping and how pathway-level genetic insight adds context to your resilience.

ADHD is highly heritable, and dopamine-system genes like DRD4, SLC6A3 (DAT1), and COMT shape attention and focus. This article explains how these pathways work, what genetic testing can and cannot tell you about attention, and why ADHD remains a clinical diagnosis rather than a DNA result.

Genetics explain roughly 50–60% of reaction-time differences, driven by genes such as COMT and BDNF that tune dopamine clearance and neuroplasticity. This guide explains how reaction time works, what your DNA contributes, and evidence-based habits — sleep, exercise, and practice — that sharpen cognitive speed.
