During the decades I have spent in academic medicine and psychiatry, I have read countless inspired theories and hypotheses concerning diseases and their treatments. Unfortunately, few have panned out. Scientists were going to cure schizophrenia with renal dialysis. Personally, I was going to alleviate tardive dyskinesia and depression with the dietary neurotransmitter precursors lecithin and tyrosine.
Fortunately, medical science is not a religious faith. The nature of empiricism allows for hypotheses to be proved—or more commonly, disproved. That’s been the story of my career and, sadly, most psychiatric science of the last century. But in our healing arts, it’s better to face the truth.
Doesn’t it stand to reason that if we inhibit both the norepinephrine and serotonin reuptake pumps, we should heal more depressed people than if we block only the serotonin transporter? A study called PREVENT showed that not to be the case.
And if we administer long-acting injectable antipsychotic medicines to patients with schizophrenia, shouldn’t we lower the relapse rate more than if we depend on their taking oral tablets? Again, no. An upcoming article in Biological Therapies in Psychiatry—“Does LAIR Beat Oral Antipsychotics?”—bursts this very logical bubble.
Someday, we’ll reach “personalized medicine” in psychiatry. Someday, more good theories will prove true than not. We’re not there yet.
