Patients with Alzheimer's disease may suffer the same age- and disease-related changes to sleep as their age-matched peers. However, as the dementia progresses, even more severe disturbances develop, with impairments in both nighttime sleep continuity and daytime alertness. This article focuses on long-term, holistic approaches to treatment, including environmental and behavioral interventions to augment sleep medications.

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.

New mothers may present to the emergency department (ED) with symptoms ranging from mild anxiety to severe psychosis. Postpartum psychosis has abrupt onset and severe symptoms and usually occurs in the immediate postpartum period. Patients who have had a previous episode of postpartum psychosis or have first-degree relatives with postpartum psychosis or bipolar disorder are at higher risk.

Women with postpartum depression frequently experience intrusive, obsessive ruminations that are part of a depressive episode. Many women with postpartum depression have significant anxiety, and many reach the level of meeting criteria for full-blown anxiety disorders. An anxiety disorder may also precede and contribute to the development of a depressive episode.

There is growing epidemiologic and clinical data that confirm progressive hypothalamic-pituitary-gonadal hypofunctioning in aging men. What role does the HPG axis play in the complex psychobiology of male sexual and affective disorders? The treatment rationale, clinical indications and risks in using exogenous testosterone for late-life depression are explored.

In recent years, depression and stress have emerged in the discussion of the impact of psychosocial aspects on coronary heart disease. Several studies indicate that these factors result in risk elevation comparable to hypercholesterolemia and hypertension.

Health-related quality of life can provide a simultaneous and net assessment of the therapeutic and adverse affects of psychiatric treatments for depression. While the cognitive side effects of ECT might be thought of as a limiting factor in HRQOL gains, they have not been systematically studied until recently. Find out what quantitative assessment of HRQOL following ECT for major depressive disorder shows.

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.

When a family member is diagnosed with depression the whole family is affected. Additional family and marital stresses imposed on the patient with depression can add to the severity of depression and affect long-term remission rates. In order to ensure the best possible success in treatment, the therapist should integrate the family into the patient’s treatment.

New Clinical Drug Evaluation Unit presented new clinical data at their 45th annual meeting in Boca Raton, Fla. In the first of two articles, suicide studies, the effectiveness of antidepressants and the efficacy of drug combination therapy are explored.

The incidence of polypharmacy is on the rise, and with the increase comes a greater risk of drug-drug reactions. One survey estimated that patients seeing a psychiatrist may be six times more likely to receive multiple psychotropic medicines compared to patients seen by a primary care physician. This article provides an overview of the extent of polypharmacy, the factors driving the phenomenon and issues clinicians should consider when treating patients who are already taking medicines for other illnesses.

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.

Through the Times With Max Fink, M.D. by Arline Kaplan Long viewed as a pre-eminent researcher and advocate for electroconvulsive therapy, Max Fink, M.D., reflects on more than five decades of groundbreaking research.

Evidence-Based Therapies in Child and Adolescent Psychiatry by Jon McClellan, M.D. Given the lack of large, randomized controlled studies of psychiatric medications that involve children and adolescents, it can be difficult to establish evidence-based therapies that are effective for this population. However, there are studies that have shown the effectiveness of various medications, as well as for various psychotherapy techniques.

Updates Show Progress in TMS for Depression and Schizophrenia by Arline Kaplan In research presented at the 2005 APA annual meeting, transcranial magnetic stimulation is showing efficacy in treating depression and schizophrenia in the research setting. The question of how to translate those findings to a real-world setting still remains.

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.
