DSM-IV-TR emphasizes that patients with borderline personality disorder (BPD) show a "instability of interpersonal relationships, self-image, and affects, and marked impulsivity beginning by early adulthood and present in a variety of contexts," and any five out of nine listed criteria must be present for the diagnosis to be made.

Paraphilias as defined by DSM-IV, are sexual impulse disorders characterized by intensely arousing, recurrent sexual fantasies, urges and behaviors (of at least six months' duration) that are considered deviant with respect to cultural norms and that produce clinically significant distress or impairment in social, occupational or other important areas of psychosocial functioning. The common paraphilias described include exhibitionism (exposure of genitals to a stranger), pedophilia (sexual activity with a prepubescent child, generally 13 years of age or younger), voyeurism (observing others' sexual activities), fetishism (use of inert objects, such as female undergarments), transvestic fetishism (cross-dressing), sexual sadism (inflicting suffering or humiliation), sexual masochism (being humiliated, beaten, bound or made to suffer) and frotteurism (touching, rubbing against a nonconsenting person).

Published a decade ago, the original National Comorbidity Survey focused largely on anxiety and depression. In an exclusive interview, the survey's designer, Ronald C. Kessler, Ph.D., talks with Psychiatric Times about the just-published replication study, which found that the combined lifetime prevalence of impulse control disorders is higher than that for either mood or substance use disorders.

Over the past decade, there has been increasing attention to the identification and management of mood and anxiety disorders related to childbearing. Emergen- cy physicians, including psychiatrists, primary care providers, obstetricians, gynecologists, and pediatricians, encounter women who are struggling with mental health issues in the context of reproductive events, such as pregnancy, pregnancy loss, and the postpartum adjustment period. In some cases, the reproductive event may precipitate a mental health crisis. In others, it may exacerbate an underlying mental health condition that, in turn, may need to be managed differently because of issues related to pregnancy or breast-feeding.

Recent evidence suggests that reorganization of neuronal connectivity might play an important role in the pathophysiology of mood disorders and in both pharmacological and psychological treatments of depression. This evidence suggests a new framework for the etiology of mood disorders that focuses more on the problems in neuronal connectivity, plasticity and information processing in the brain than on abnormalities in chemical neurotransmission. Although this framework is still controversial and far from being complete, improved familiarity with the concepts of neuronal development and activity-dependent plasticity among mental health professionals would be useful.

Comorbidity of Dysthymic Disorders in Children and Adolescents by Atilla Turgay, M.D. Many patients with dysthymic disorders also have associated comorbid disorders. A detailed history will provide insight into the comorbidity profile, cross-sectionally and developmentally. Dysthymic disorder should be addressed clinically, as it may cause long-term chronic unhappiness and poor quality of life for the patient.

The Emerging Role of GABAergic Mechanisms in Mood Disorders by Po W. Wang, M.D., and Terence A. Ketter, M.D. Gamma-aminobutyric acid is a major inhibitory neurotransmitter widely distributed in the mammalian central nervous system. Animal models of depression have pointed toward the importance of the GABA system in the pathophysiology of mood disorders. Thus, elucidating the GABAergic effects of benzodiazepines, mood stabilizers, antidepressants, and new anticonvulsants and antipsychotics may expand our understanding of mood disorder pathophysiology and potentially generate new targets for treatment.

Suicidal behavior is a complex and multi-factorial phenomenon for which epidemiological genetics suggests a genetic basis that may be specific and independent from those implicated in the vulnerability to the psychiatric disorders associated with SB. Recently, new molecular biology tools have been designed to identify predisposition factors to complex disorders. One of the main goals of current studies is to specify the suicidal phenotype, as well as the intermediate phenotypes associated with these genes.

Three recently published studies uncovered some answers to the genetic underpinnings of depression. Familial vulnerability was shown to increase with each generation affected by depression. Two genetic variants pointed in opposite directions: one showed an increase risk of depression and the other predicted responsiveness to antidepressants.

The post-stroke patient is at significant risk for various psychiatric syndromes. The most commonly reported of these in the literature are post-stroke depression (PSD) and post-stroke dementia (PSDem), which may present simultaneously with overlapping mood and cognitive symptoms. In this article, we offer a review of current literature on post-stroke psychiatric syndromes and an integrated clinical approach to screening, diagnosis, and pharmacologic intervention.

Patients with anorexia nervosa often attempt to deceive health care professionals because they do not want treatment for their disorder. Thus, physicians must maintain a high index of suspicion for signs and symptoms of AN due to its potentially fatal complications.

Borderline personality disorder is a complex, disabling disorder. The chairperson for the American Psychiatric Association workgroup for the evidence-based practice guideline on its treatment gives an overview of this disorder's etiologies, neurobiology, longitudinal course and recommended treatments. Future directions for both treatments and research are also discussed.
