Are mental illnesses genetic?

Author's Note: Are mental illnesses genetic?

When we find out (or suspect due to our family histories) that we're genetically predisposed to such conditions as cardiovascular diseases or cancer, many of us want preventative measures and we want them now. A healthy lifestyle, and maybe cholesterol-lowering medications, may help prevent you from having a heart attack. And cancer? Angelina Jolie, for example, took a proactive stance against breast cancer after testing positive for the high-risk mutation in the BRCA-1 gene -- in 2013 she underwent a voluntary double mastectomy. Are we close to the day when we'll be able to preventively treat our mental health as we do other chronic conditions?
