Do genetics hold the key?

Hope Virgo explores the link between genetics and mental health issues, and how advances in research are helping our understanding

I have always wondered why I developed anorexia while none of my brothers and sisters did (I am one of five). While there were others in my wider family diagnosed with mental health issues and eating disorders, I still sometimes wonder: “Why me?” And what does this all mean for my son? Will the genetic predisposition overrule the way I bring him up or can I do more to prevent him developing a mental health issue himself?
