Genetics of Mental Illness

Genetics of mental illness involves how our inherited DNA influences brain function and susceptibility to conditions like depression, anxiety, or schizophrenia. Certain genes can affect brain chemicals, structure, or development, increasing risk, but they don't directly cause the illness. Usually, genetics interact with environmental factors, such as stress or trauma, to influence mental health. While no single gene determines a diagnosis, a family history can increase vulnerability, highlighting the complex interplay between genetics and life experiences in mental health.
