“With an estimated 44 million adults affected, chances are that you know someone with a mental disorder. Many scientists believe that a variety of these brain ailments arise from complicated interactions between multiple genes and the environment. Now new technologies, including a tool known as a microarray that allows researchers to evaluate thousands of genes in a single experiment, are helping push the field forward. In examples of recent work, microarray studies provided insights into how sets of genes link to depression and schizophrenia. Altogether, new findings are helping researchers better understand the underpinnings of mental disease so they can develop improved treatments.” Brain Briefings
