Yes, that's the theory of the medical community, like what came first, the chicken or the egg; really, we'll never know, but the medical community are bold enough to say they know it's absolutely the egg.....although they have no real proof of that.
You are entitled to your opinion. Here's mine...it isn't chemical imbalance that causes one to self-medicate. To me it seems most people with troubled lives. horrible lives, go looking for relief sometimes. Relief can come in a bottle, pill or needle. Sometimes it can happen just when someone is attempting to bond with others, to be part of something. Peer pressure, family pressure, life pressure....drugs just will take it all away.
Of course, then once a person is into it, the brain does crave it or needs it to feel normal or good since it starts to depend on the drug for that; at the same time, it tries to build tolerance by setting up opposing neurotransmitters... there's the real chemical imbalance.
Then there is the issue of "accidental addiction". Some pharmaceuticals can cause physical dependancy, tolerance and tolerance withdrawals. Those things can lead to higher need of the brain to have the drugs in order to function since the brain gets used to the chemical doing all the work so now it can't. Plus the brain still tries to build tolerance as self-defense, creating opposing neuros to combat the drug and maintain homostatis. But again, this is not normal and the balance of proper neuros is out of sorts as a result.
Anyway, "downregulation" of receptors is known to happen when the brain receptors are continually exposed to a drug. Downregulation is a desensitizing of receptors or a sort of dying off of them. This would seem to be a form of functional brain damage.
So drugs themselves, for whatever reason one is on them or starts them, can cause changes in the brain. Other psychoactive substances are also culprits such as alcohol and cigarettes.
Chicken or the egg? I don't claim to really, absolutely know but it does seem that most mentally ill people, I'm talking the truly ill ones...not ones with shyness or PMS....have a history of drugs/chemicals in one form or another so with that consistancy I would be highly suspect of the drugs since drugs do, in time, show considerable ability to damage normal brain functions.
I've read that, with drug-free time, the brain can recover from downregulation. But it could take months/years for complete recovery in some people and that's where sometimes people just cannot do it or are mistakenly told they'll never be able to do without some sort of drug so that fear keeps them on something.
But of course, I'm not saying every single case of mental illness is created ONLY by drugs or alcohol....that would be like saying there is only one cause of cancer.
But, drugs seem to be in the top catagory of suspects.
