This does not describe the doctors I work with every day. Sorry about yours. The fact remains, and unremarked in this article, is that the most common misdiagnosis in geriatrics is to diagnose treatable depression as dementia. I couldn't count the "demented" patients I have seen who have cognitively cleared once antidepressant medication was begun.
Gee, I can only report on things overheard in the doctors lounge (keeping my anonymity at the foremost). ;-)
I can write a book. Stay away from their darned drugs.
