This term, "prescription cascade", should be lesson #1 at medical school. It's the natural result of an incomplete diagnosis, and is present in every medical field.
> At the hospital, where she stayed for two weeks, she was put on a new combination of pills: Lamictal, a mood stabilizer; Lexapro, an antidepressant; and Seroquel, an antipsychotic that she was told to use as a sleep aid.

These descriptions -- mood stabilizer, antidepressant, antipsychotic -- are just marketing terms that don't actually describe the actual function of the drug. These marketing terms are most useful for tricking medical professionals into prescribing these products.

This is the trap the mental health system has fallen into: the professionals want to help. The drug industry has FDA-approved drugs for the various diagnosises.
Joel on Software said a re-write is something that shouldn't be done. But what other choice does the mental health industry have? Their system doesn't work. The modern industry is based on the flawed chemical imbalance theory of mental illness.
Little bits of progress have been made, in spite of the inertia to treat misunderstood behavioral problems with patent medicines.
