Mental Health Official Softens Stance on New Psychiatric
Debate over the validity of the latest version of what is
considered the diagnostic "bible" of psychiatry eased Tuesday after
a top government health official who had criticized the manual
softened his position in a public statement.
Set to be released Saturday, the fifth edition of the Diagnostic
and Statistical Manual of Mental Disorders (DSM) is published by
the American Psychiatric Association (APA). This latest edition has
raised some concerns because of changes in the diagnoses of some
disorders, most notably in the area of autism spectrum
But the issue that Thomas Insel, director of the U.S. National
Institute of Mental Health (NIMH), recently took with the manual
was more fundamental.
Insel wrote in a blog post that the manual is "at best, a
dictionary, creating a set of labels and defining each," and that
its "weakness is its lack of validity."
In his post, Insel added that his agency would instead steer its
research toward a new set of diagnostic parameters known as
Research Domain Criteria (RDoC), because "DSM diagnoses are based
on a consensus about clusters of clinical symptoms, not any
objective laboratory measure."
However, in a joint release issued Monday, Insel and APA
president-elect Jeffrey Lieberman noted that the DSM-5 "represents
the best information currently available for clinical diagnosis of
The new statement further clarified that while the manual is
used by practitioners, it "is no longer sufficient for
researchers," and so RDoC will be the new focus for NIMH.
"Looking forward, laying the groundwork for a future diagnostic system that more directly reflects modern brain science will require openness to rethinking traditional categories," the statement explained. "This is the focus of the NIMH's Research Domain Criteria [RDoC] project. RDoC is an attempt to create a new kind of taxonomy for mental disorders by bringing the power of modern research approaches in genetics, neuroscience and behavioral science to the problem of mental illness."
The latest statement also pointed out that the DSM and RDoC
"represent complementary, not competing, frameworks. . . . As
research findings begin to emerge from the RDoC effort, these
findings may be incorporated into future DSM revisions and clinical
U.S. Files Appeal to Delay Non-Prescription 'Morning After'
The Obama administration on Monday filed an eleventh-hour appeal
to delay the over-the-counter sale of "Plan B" emergency
contraception to girls of any age.
Last month, U.S. District Judge Edward Korman ruled that the
so-called "morning after" pill be made available without a
prescription, with a deadline for any appeal set for Monday. On
Friday Korman denied a U.S. government request to put a hold on his
order while the Obama administration readied an appeal.
The appeal was filed Monday just before the noon deadline, the
Associated Pressreported. In the document, the government
contends that Korman overstepped his authority.
But Korman said politics are driving moves by U.S. Health and
Human Services Secretary Kathleen Sebelius to block
over-the-counter access to Plan B. Earlier this month, the U.S.
Food and Drug Administration lowered the age limit for access to
the emergency contraceptive from 17 to 15 years of age, but Korman
believes that doesn't go far enough.
In the meantime, the Center for Reproductive Rights, which
instigated the lawsuit behind Korman's decision, said it would
answer the Obama administration's filing within 10 days, the
APreported. In papers filed before the court, the center
said that delays in access to Plan B could be "life-altering" for
some women, the
