(Whitaker originally was a highly regarded medical reporter at the Albany Times Union and also wrote off and on for the Boston Globe. A series he co-wrote for the Boston Globe on harmful psychiatric research was a finalist for the Pulitzer Prize in 1998. When he began his investigative research into psychiatric issues, Whitaker was still a believer in the story of progress that psychiatry has been telling the public for decades.)

| SS: Let’s now move from the antidepressants like Prozac to consider another new group of supposed wonder drugs -- the new antipsychotic drugs. You write that long-term use of antipsychotic drugs -- both the original neuroleptic drugs like Thorazine and Haldol and the newer atypicals like Zyprexa and Risperdal -- cause pathological changes in the brain that can lead to a worsening of the symptoms of mental illness. What changes in brain chemistry result from the antipsychotics, and how can that lead to the most frightening prospect you describe -- chronic mental illness that is locked in by these drugs? RW: This is a line of research that goes across 40 years. This problem of chronic illness shows up time and time again in the research literature. This biological mechanism is somewhat well understood now. The antipsychotics profoundly block dopamine receptors. They block 70-90 percent of the dopamine receptors in the brain. In return, the brain sprouts about 50 percent extra dopamine receptors. It tries to become extra sensitive. So in essence you’ve created an imbalance in the dopamine system in the brain. It’s almost like, on one hand, you’ve got the accelerator down -- that’s the extra dopamine receptors. And the drug is the brake trying to block this. But if you release that brake, if you abruptly go off the drugs, you now do have a dopamine system that’s overactive. You have too many dopamine receptors. And what happens? People that go abruptly off of the drug, do tend to have severe relapses. SS: So people that have been treated with these antipsychotic drugs have a far greater tendency to relapse, and have new episodes of mental illness, as opposed to people who have had other kinds of non-drug therapies? RW: Absolutely, and that was understood by 1979, that you were actually increasing the underlying biological vulnerability to the psychosis. And by the way, we sort of understood that if you muck with the dopamine system, that you could cause some symptoms of psychosis with amphetamines. So if you give someone amphetamines enough, they’re at increased risk of psychosis. This is well known. And what do amphetamines do? They release dopamine. So there is a biological reason why, if you’re mucking up the dopamine system, you’re increasing the risk of psychosis. That’s in essence what these antipsychotic drugs do, they muck up the dopamine system. Here’s just one real powerful study on this: Researchers with the University of Pittsburgh in the 1990s took people newly diagnosed with schizophrenia, and they started taking MRI pictures of the brains of these people. So we get a picture of their brains at the moment of diagnosis, and then we prepare pictures over the next 18 months to see how those brains change. Now during this 18 months, they are being prescribed antipsychotic medications, and what did the researchers report? They reported that, over this 18-month period, the drugs caused an enlargement of the basal ganglia, an area of the brain that uses dopamine. In other words, it creates a visible change in morphology, a change in the size of an area of the brain, and that’s abnormal. That’s number one. So we have an antipsychotic drug causing an abnormality in the brain. Now here’s the kicker. They found that as that enlargement occurred, it was associated with a worsening of the psychotic symptoms, a worsening of negative symptoms. So here you actually have, with modern technology, a very powerful study. By imaging the brain, we see how an outside agent comes in, disrupts normal chemistry, causes an abnormal enlargement of the basal ganglia, and that enlargement causes a worsening of the very symptoms it’s supposed to treat. Now that’s actually, in essence, a story of a disease process -- an outside agent causes abnormality, causes symptoms... |

about this. I have had two people in my life with untreated BPD and I have learned a lot. One friendship I have had to distance myself from because it was so draining. The other person is my mother and because of her age and other health concerns the BPD will never be treated so I have had to learn a lot of coping skills and a lot about the disorder. There is a lot of misinformation out there.
). But I kind of feel unfairly maligned. I mentioned the reason I was prescribed a particular drug. It's not an unusual drug to be used for that dx with my symptoms, especially since BPD is not really an illness per se, more a combination of behaviors. Because of this it is usually necessary to treat the behaviors, either through drugs or therapy. In response to my mention of a dx/drug combo I was told that my doctor was wrong and that I need a different treatment.
