Thinking Clearly About Personality Disorders

Thinking Clearly About Personality Disorders

SEOOKE.com: This weekend the Board of Trustees of the American Psychiatric Association will vote on whether to adopt a new diagnostic system for some of the most serious, and striking, syndromes in medicine: personality disorders.

Personality disorders occupy a troublesome niche in psychiatry. The 10 recognized syndromes are fairly well represented on the self-help shelves of bookstores and include such well-known types as narcissistic personality disorder, avoidant personality disorder, as well as dependent and histrionic personalities.

But when full-blown, the disorders are difficult to characterize and treat, and doctors seldom do careful evaluations, missing or downplaying behavior patterns that underlie problems like depression and anxiety in millions of people.

The new proposal — part of the psychiatric association’s effort of many years to update its influential diagnostic manual — is intended to clarify these diagnoses and better integrate them into clinical practice, to extend and improve treatment. The entire exercise has forced psychiatrists to confront one of the field’s most elementary, yet still unresolved, questions: What, exactly, is a personality problem?

Habits of Thought

Personality problems aren’t exactly new or hidden. They play out in Greek mythology, from Narcissus to the sadistic Ares. They percolate through biblical stories of madmen, compulsives and charismatics. They are writ large across the 20th century, with its rogues’ gallery of vainglorious, murderous dictators.

Yet it turns out that producing precise, lasting definitions of extreme behavior patterns is exhausting work. It took more than a decade of observing patients before the German psychiatrist Emil Kraepelin could draw a clear line between psychotic disorders, like schizophrenia, and mood problems, like depression or bipolar disorder.

Likewise, Freud spent years formulating his theories on the origins of neurotic syndromes. And Freudian analysts were largely the ones who, in the early decades of the last century, described people with the sort of “confounded identities” that are now considered personality disorders.

Their problems were not periodic symptoms, like moodiness or panic attacks, but issues rooted in longstanding habits of thought and feeling — in who they were.

“A pedantic sense of order is typical of the compulsive character,” wrote the Freudian analyst Wilhelm Reich in his 1933 book, “Character Analysis,” a groundbreaking text. “In both big and small things, he lives his life according to a preconceived, irrevocable pattern.”

Others coalesced too, most recognizable as extreme forms of everyday types: the narcissist, with his fragile, grandiose self-approval; the dependent, with her smothering clinginess; the histrionic, always in the thick of some drama, desperate to be the center of attention.

In the late 1970s, Ted Millon, scientific director of the Institute for Advanced Studies in Personology and Psychopathology, pulled together the bulk of the work on personality disorders, most of it descriptive, and turned it into a set of 10 standardized types for the American Psychiatric Association’s third diagnostic manual. Published in 1980, it is a best seller among mental health workers worldwide.

These diagnostic criteria held up well for years and led to improved treatments for some people, like those with borderline personality disorder. Borderline is characterized by an extreme neediness and urges to harm oneself, often including thoughts of suicide. Many who seek help for depression also turn out to have borderline patterns, making their mood problems resistant to the usual therapies, like antidepressant drugs.

Today there are several approaches that can relieve borderline symptoms and one that, in numerous studies, has reduced hospitalizations and helped aid recovery: dialectical behavior therapy.

This progress notwithstanding, many in the field began to argue that the diagnostic catalog needed a rewrite. For one thing, some of the categories overlapped, and troubled people often got two or more personality diagnoses. “Personality Disorder-Not Otherwise Specified,” a catchall label meaning little more than “this person has problems” became the most common of the diagnoses.

The assessment interviews can last hours, and treatments for most of the disorders involve longer-term, specialized talk therapy.

Resisting Simplification 

The most central, memorable, and knowable element of any person — personality — still defies any consensus.

A team of experts appointed by the psychiatric association has worked for more than five years to find some unifying system of diagnosis for personality problems.

The panel proposed a system based in part on a failure to “develop a coherent sense of self or identity.” Later, the experts tied elements of the disorders to distortions in basic traits.[nyt]
