There is a shortage of psychiatrists right now -- in part because of the last time the gov't got into the act and restricted the supply of new doctors about 20 years ago. As the US population continues to age, dementia will become even more of a problem than it is today, and the need for psychiatrists will continue to increase.
Kalifornia needs more psychiatrists because at least 20% of the population there admits to needing help.
Dementia is not a psychological condition. it's a medical one.
Not a damn thing a shrink can do for dementia. It's caused by one or more organic brain diseases, and unfortunately, there are few if any drugs that actually help in any significant way, either. There is no treatment. Quite frankly, the end game here is a locked facility. My wife works in this field, so I get to hear all about it. Not in all the years has she ever indicated a single person with dementia was seeing a shrink, and she's gonna burst out laughing (or crying) when I mention the idea to her.
