Abortion Pill May Help Treat Severe Form of Depression
Erica Goode, New York Times- 10/23/2002
Mifepristone, once called RU-486, is best known as the abortion pill. But some
scientists believe that the drug may eventually serve another, far less controversial,
purpose: treating a particularly fierce and intractable form of depression. Two small
studies, the latest appearing last month in the journal Biological Psychiatry, have found
that mifepristone is effective in helping people whose severe depression is accompanied by
delusional beliefs or hallucinations. Of the 30 patients in the recent study, those who
took mifepristone for seven days at dosages higher than those used for abortions showed
substantial and rapid improvement in their symptoms, the researchers found. The drug
produced only mild side effects in the study.
Encouraged by such findings, Corcept Therapeutics, the small California
pharmaceutical company that financed the second study, has applied to the Food and Drug
Administration for approval to market mifepristone for psychotic depression, and two large
clinical trials of the drug are in progress. (Danco Laboratories of New York manufactures
and distributes mifepristone, sold as Mifeprex, for ending pregnancy.) Dr. Joseph K
Belanoff, a psychiatrist and Corcept's chief executive, said the drug could be available
within five years "if everything went well" and mifepristone was found to be
safe, as used in the study, and effective for the disorder. Dr. Belanoff was also the lead
author of the study published in the journal in September.
If mifepristone does reach the market, it will be the first medication
specifically approved for psychotic depression, which psychiatrists say is the most
difficult form of depression to treat. The illness accounts for 15 percent to 19 per-cent
of the cases of severe depression diagnosed in the United States, according to a study by
Dr. Maurice M. Ohayon and Dr. Alan Schatzberg of the, Stanford medical school to appear
soon in The American Journal of Psychiatry. Dr. Schatzberg, Stanford's chairman of
psychiatry, is a founder of Concept Therapeutics and a shareholder in the privately held
company.
Patients with psychotic depression often suffer from delusions,
believing, for example, that they deserve punishment for imagined crimes or that they have
terminal illnesses. Psychiatrists have traditionally treated psychotically depressed
patients with some combination of antidepressants, antipsychotic drugs and electroshock
therapy, an approach that has yielded only moderate success. But the investigators hope
that mifepristone, which patients would take for a short period then return to the usual
course of treatment, will relieve symptoms more quickly and effectively.
A chemical compound used for abortions may seem an odd candidate for a
depression drug. But mifepristone attracted the attention of researchers for good reason.
Mifepristone induces abortion by blocking the action of progesterone, a hormone necessary
for implanting a fertilized egg in the lin-ing of the uterus. But in higher doses, the
drug also blocks another hormone, cortisol, which is secreted by the adrenal glands and
plays a critical role in the body's response to stress. Patients with psychotic
depression, studies have shown, often have elevated lev-els of cortisol.
Dr. Anthony Rothschild, a professor of psychiatry at the University of
Massachu-setts Medical School, who has studied psychotic depression, said he and Dr.
Schatzberg had hoped to test RU-486 as a treatment in the late 1980's. "You just
couldn't get it because of the political controversy," Dr. Rothschild said. Dr.
Dennis Charney, the director of the mood and anxiety disorders research program at the
National Institute of Mental Health, said scientists at first assumed that the elevated
cortisol levels found in some severely depressed patients were only indirectly related to
their illness. In the last few years, however, researchers have demonstrated that stress
hormones can have a significant effect on brain areas involved in memory formation,
emotion and other mental functions.
The preliminary studies of mifepristone, said Dr. Charney, an author of
a commentary accompanying the recent journal article, suggest that cortisol may be
directly connected to the delusions and severe depression that patients experience. Such
research, he said,. "suggests that cortisol may be mediating a lot of the symptoms
associated with mood disorders." Prednisone, a drug closely related to cortisol, can
sometimes produce mood changes and psychosis as side effects, Dr. Charney noted. Still, he
said, more research is required before the effectiveness of mifepristone can be confirmed.
The study published last month, for example, was not double-blinded, a
protection that prevents the experimenters from knowing whether a patient is taking the
drug being tested or a dummy pill. Dr. Belanoff said the results of the first large
double-blinded clinical trial, of 200 patients at 25 medical centers around the country,
would be available early next year. A second trial is in the early stages.
Dr. Belanoff confirmed that one patient in the first clinical trial, a
49-year-old man, had died during the study. But he said an autopsy concluded that the man,
who had been taking 11 other medications in addition to mifepristone, died from congestive
heart failure, brought on by high blood pressure and heart disease, and that it was
unlikely that the death was related to his participation in the clinical trial.
Even if mifepristone wins approval as a treatment for psychotic
depression, the drug's controversial history may make it difficult to dispense, perhaps
restricting its use to hospital wards. When, in 2000, the F.D.A. finally approved Mifeprex
for abortions, it placed tight restrictions on its use. And the continuing debate over
chemical abortion will probably ensure that similar restrictions are applied to
mifepristone in any form, even one intended to help the most severely depressed patients.
Patterns Seen in Murderers' Brains
Ned Potter, ABC News- 10/24/2002
Joel Rifkin strangled 17 prostitutes in four years, at random and without remorse. But
years after New York police caught him in 1994, he still said he had no idea why he
killed. "It was just something that happened and, you know, I had no plans to repeat
it," Rifkin said in an interview from prison, where he is serving a life sentence.
"Am I just evil? Am I brain-damaged? I mean, these are questions I want
answered." So do a lot of scientists. Using imaging techniques that allow them to map
the brain with growing precision, they have found subtle but similar patterns in the brain
activity of people who commit violent crimes.
The Frontal Lobe
In the 1990s a research team -- led by Adrian Raine of the University of Southern
California and Monte Buchsbaum, now at Mount Sinai School of Medicine in New York - did
brain scans of 25 convicted murderers. They found that many of the killers had
abnormalities in the front sections of the brain -- the so-called frontal lobes. "In
the normal person the frontal lobe is one of the most highly active areas of the
brain," says Buchsbaum, calling up an image on his computer. He points at a brightly
colored cross-section of a man's brain on the screen. "In this individual, who
carried out a murder, we can see that the frontal lobe is quite inactive."
Why does that matter? Because scientists have found that parts of the
frontal lobes seem to be involved in planning and organizing, and - perhaps most important
to the understanding of violent crime - impulse control. "The frontal lobes are the
part of the brain that put a brake on impulses and drives," says Dr. Jonathan Pincus,
a psychiatrist at Georgetown University in Washington. "It's the part of the brain
that allows us to say, 'Don't do that! Don't say that! It's not appropriate! There are
going to be consequences!'" Pincus has examined brain scans of more than 100 killers,
including some of Rifkin. He says Rifkin matches many other offenders he's seen: "His
frontal lobes were very, very seriously damaged."
Understanding Criminal Urges
That brain deficiency alone is not enough to make a person violent. Researchers say people
with poor impulse control may simply seem poorly organized, or socially inept. Researchers
cite a myriad of other factors - ranging from schizophrenia to severe abuse in childhood -
that may play roles. If a person was badly abused, says Pincus, there may be anger waiting
to be released. If the person also has frontal lobe deficiency, he says, "then you
have a very dangerous combination of impulses and drives that cannot be easily controlled
by the damaged frontal lobes."
Buchsbaum warns against reading too much into this. Research has moved
gradually, partly because doctors do not want to create a false impression that they are
looking for ways to excuse violence. Researchers also agree it is far too early to say
anything about the serial sniper slayings in Maryland, Virginia and Washington, D.C.
"We can't specifically say, 'This person will be a sniper and at age 30 will carry
out such-and-such a crime.' That is fundamentally impossible," Buchsbaum says.
"What we can do is understand the underlying dimensions of impulse control - how the
brain stops behavior - and perhaps we can learn to strengthen this, with educational
strategies, or with drugs." Meanwhile, Joel Rifkin concedes that if he were ever set
free, he is not sure he could prevent himself from killing again.
Forum on Child Abuse Eyes Role of Age
Patricia Wen, Boston Globe- 10/25/2002
WALTHAM - The tale of Sam Stone and the preschoolers captivated more than 150
Massachusetts judges, lawyers, and therapists at a conference yesterday on the abuse of
children. In an experiment described at the conference, 170 preschool children between the
ages of 3 and 6 were told about a man named Sam Stone who was clumsy and broke things. Sam
Stone soon visited the classroom, walked around barely touching anything, and left. Weeks
later, teachers asked the children leading questions about Sam Stone, ''reminding'' them
that he had ripped books and damaged teddy bears in the classroom. More than 70 percent of
the children between the ages of 3 and 4 agreed that Sam Stone had damaged those things --
some even describing the events in great detail -- while 65 percent of the preschoolers
ages 5 and 6 said Sam Stone did nothing of the sort. ''This shows you can create false
stories in children,'' said Thomas Lyon, a professor at the University of Southern
California Law School.
The role of age in the validity of a child's testimony, particularly in
tense custody disputes that include charges of sexual abuse, was one of the topics at the
conference. The two-day meeting, aimed at helping the courts better protect children who
are physically or sexually abused, was held at the Massachusetts Medical Society
headquarters. Given how traumatic it can be for children to recount these events, speakers
emphasized the need to minimize the times children are forced to relive experiences for
the benefit of the court.
One in four to five girls and one in seven to 10 boys is abused before
turning 18, according to the Massachusetts Citizens for Children, which sponsored the
event that ends today. In 90 percent of the cases, the child knows and trusts the person
who commits the abuse.
Speakers also addressed the need for the court system to better
understand the psychological state of mothers upon hearing that their husband has been
accused of sexually abusing their child. Rebecca Bolen, a professor at the Boston
University School of Social Work, said such charges set up a cascade of events -
separation from the husband, loss of income, loss of family structure - that compound the
crisis. Too often, she said, these women are perceived as ''hysterical'' when they need
more mental health support. Judges talked about the agonizing choices they make each day
in sex abuse cases. Juvenile Court Judge Stephen Limon said in the early 1980s, the court
system used to believe that ''kids don't lie,'' then in the 1990s, ''people started
questioning all kids' testimony.'' ''Now, it's coming back to the middle,'' he said. |
