With long-term use of psychoactive drugs, the result is, in the words of Steve Hyman, a former director of the NIMH and until recently provost of Harvard University, “substantial and long-lasting alterations in neural function.” As quoted by Whitaker, the brain, Hyman wrote, begins to function in a manner “qualitatively as well as quantitatively different from the normal state.” After several weeks on psychoactive drugs, the brain’s compensatory efforts begin to fail, and side effects emerge that reflect the mechanism of action of the drugs… The episodes of mania caused by antidepressants may lead to a new diagnosis of “bipolar disorder” and treatment with a “mood stabilizer,” such as Depokote (an anticonvulsant) plus one of the newer antipsychotic drugs. And so on.
Some patients take as many as six psychoactive drugs daily. One well- respected researcher, Nancy Andreasen, and her colleagues published evidence that the use of antipsychotic drugs is associated with shrinkage of the brain, and that the effect is directly related to the dose and duration of treatment. As Andreasen explained to The New York Times, “The prefrontal cortex doesn’t get the input it needs and is being shut down by drugs. That reduces the psychotic symptoms. It also causes the prefrontal cortex to slowly atrophy.”
Getting off the drugs is exceedingly difficult, according to Whitaker, because when they are withdrawn the compensatory mechanisms are left unopposed. When Celexa is withdrawn, serotonin levels fall precipitously because the presynaptic neurons are not releasing normal amounts and the postsynaptic neurons no longer have enough receptors for it. Similarly, when an antipsychotic is withdrawn, dopamine levels may skyrocket. The symptoms produced by withdrawing psychoactive drugs are often confused with relapses of the original disorder, which can lead psychiatrists to resume drug treatment, perhaps at higher doses.
Angell’s review of three books about psychoactive drugs and depression suggests that for the most part the pills don’t work, and are (see above) positively dangerous.
And what’s this got to do with universities? High-profile professors of psychiatry all over this country, some of them paid by drug companies, legitimize the use of these pills by millions and millions of Americans, including very small children.
