I actually think psychiatry as a whole, is somewhat of a grey area because what markers are used in order to determine whether a person is suffering from depression or not? Yes, the have questions and etc that supposedly help them to decide if a sufferer or not, but I truly wonder how many people are turned away and told they're fine? My bet is anyone could go see a shrink and 99% of them would be given prescriptions.
Richard mentions, poor eating habits, smoking and drinking, and hints that this indicates depression, but yet all three of these are part of my daily life, and yet I certainly don't consider myself to be suffering from depression. Sure there are times when I feel down, but if you ask me, that's perfectly normal.
I also believe that mood/depression and etc can be manipulated through diet and exercise.
Another grey area is ADHD in kids. A child only has to be a little bit more active that the "average" child, and they're given medication, which ironically enough, is classified as a Category II Controlled Substance, effectively putting the most common ADHD drugs in the same class as cocaine, morphine, and opium. But hey, it does make life a whole lot easier for teachers and parents. When I was a kid, the disorder was known as "naughty" and severe cases treated very effectively with a smack or a lack of pocket money. Strange how everything is a "disorder" these days.
My own daughter is clearly hyperactive, but there is no way I would even consider letting her take medication for it. And for those who say diet and exercise don't work, I'm pleased to say they do. By increasing my daughter's exercise, I have seen a huge change. Rather than suppress her energy with drugs, I allow her to burn it up naturally.
Anyway, sorry for going off topic. It's just that I'm a bit skeptical about all this psychiatry business.
