I absolutely agree! I feel there needs to be a blend between neuroscience and psychiatry/psychology. It just makes sense. I mean, for one, not everyone sits at the same level on the autistic spectrum. And while both neuroscience and psychology can find the nuances, they would also each have their own methods. It's important to understand these methodologies to both better diagnosing and can also aid in better treatment - whether that be medicine or behavioral.

It's also important to note that some mental illnesses, like depression, can be treated with medicine at first and then swapped to behavioral. Medicine is not a cure, then, it's just a way to mitigate the circumstances for the long term, or at least until they change.

I know people who have taken anti-depressants for one year and then weaned themselves off in favour of behavioral treatment. Their social and environmental circumstances changed enough for them to not need medication.

In fact, I've heard testimony from various psychologists who say that many of their patients could have a better life if they weren't disadvantaged by the world around them. If they had enough money, or had a better job, or lived in a better suburb.

As an aside: I think you might be interested in reading Incognito. It's from a neuroscientist point of view, but they guy (David Eagleman) really paints the picture on how our brains can be programmed into effective behavior.
