The biochemical basis for "functional" mental illnesses remains as elusive as ever.
This is not precisely the conclusion of this book, but almost. The authors try to be sanguine about their speciality, ending with the hope that "biochemistry may indeed contribute significantly to the ultimate solution of the mystery of mental illness."
