That was a great response and I agree. If psychologists start prescribing it will not negatively affect psychiatrists a bit. There will always be a need for psychiatrists, and my guess is we will an increased need for psychiatry when psychologists start prescribing. I noticed the more I learned about psychopharm, clinical medicine etc, the more I ordered psychiatric consults for the patients I treat, and the more I relied on psychiatry for help.
Exactly - psychiatry evolves. Remember a hundred years ago it was neurology (e.g., Freud).
In ancient greece it was almost philosophical (e.g., writings of Aristotle), in the 1940-50s it was asylum based (in the US at least - Germany and UK had advanced considerably) with ECT and the psycho-socio-politcal problems of the 1960s and involuntary treatment.
The 1980s have seen rapid psychopharm development and prescribing much more open.
The 2000s on have shown gene advances, etc., .
And all the way through has been the psychiatrist, assisted by the neurologist, the surgeon (when psychosurgery was in vogue), the psychologist (in the 1990s and hopefully always but you never know with fragile ego problems!) the internist with thyroid/diabetes/post-concussion/epileptic/you name it, the obgyn and endocrine changes of pregnancy and post-partum.
And all through it, there has been more and more recognition of psychiatry as vital to a healthy society - e.g., the high funding in europe and the slaughter of psychiatry by managed care in the US (but I'll leave my politcal views for another time).
The future is bright, regardless.
