Steadily emerging from the research of neuroscience are new approaches and new treatments for mental illness. The use of psychiatric drugs could be replaced in the future. Rather than developing new medicines there is more focus on research that looks at how the neural circuits in the brain can be altered by physical intervention into the brain itself.
This new research focuses not only on how each network of the brain works but also how it interacts with the other neural networks within the brain. The idea is that by researching into these neural networks more specific treatments for mental illness can be created.
