Yes, but I think the film brings up a good point. A patient is subjectively diagnosed with a "chemical imbalance", in which no test can confirm or refute, then prescribed medication to "fix" this chemical imbalance for an indefinite amount of time and with no measurable outcome. Correct me if I'm wrong, but would that ever fly in non-experimental medicine?quote]
It's unrealistic to say that there is NO measurable outcome. I had an internship for a year at an out-patient clinic for people with schizophrenia. The part of the clinic I worked in ran several studies at a time regarding the effectiveness of therapy, drugs, etc. If someone with schizophrenia (or another diagnosis) comes in exhibiting X, Y, and Z symptoms that significantly hinder their life to the point that they can't hold down a job, live on their own, maintain relationships, or clean themselves and then they receive therapy, a prescription, or both and then several weeks later they CAN get a job, live on their own, etc. then I would argue that the above would be considered a measurable outcome. Is it a definite test? No. Is it easy to measure that a person's life is more manageable and improved. Yes.
