Antidepressants constitute a central cornerstone in the treatment of depressive syndromes. In bipolar patients, however, there is an ongoing controversy about their usefulness for at least 3 decades. Early reports, mainly concerning tricyclic antidepressants, have repeatedly pointed toward unfavorable side effects on the course of the disorder, namely switching into (hypo)mania, induction of rapid cycling, and increased risk of suicide. Most evidence for both unfavorable and favorable effects has been deducted, thus far, from small studies with methodological flaws. More substantiated evidence only recently became available. From this it appears that, at least, the switch risk, and perhaps also the risk for rapid cycling and new-onset suicidality have been overinterpreted. At the same time, these new data raise doubt about the efficacy of anti-depressants as a primary-treatment choice in bipolar depression.

Mild cognitive impairment (MCI) is a clinical diagnosis in which deficits in cognitive function are evident but not of sufficient severity to warrant a diagnosis of dementia. For the majority of patients, MCI represents a transitional state between normal aging and mild dementia, usually Alzheimer's disease. Multiple subtypes of MCI are now recognized. In addition to presentations featuring memory impairment, symptoms in other cognitive domains (eg, executive function, language, visuospatial) have been identified. Neuropsychological testing can be extremely useful in making the MCI diagnosis and tracking the evolution of cognitive symptoms over time. A comprehensive test battery includes measures of baseline intellectual ability, attention, executive function, memory, language, visuospatial skills, and mood. Informant-bassed measures of neuropsychiatric symptoms, behaviors, and competency in instrumental activity are also included. Careful assessment can identify subtle deficits that may otherwise elude detection, particularly in individuals of superior baseline intellectual ability. As we move closer to disease-modifying therapy for Alzheimer's disease, early identification becomes critical for identifying patients who have an opportunity to benefit from treatment.

Current evidence from epidemiological, neuroimaging, pathological, pharmacotherapeutic, and clinical studies indicate an association of Alzheimer's disease with risk factors of vascular atherosclerotic disease either in isolation or in aggregate. “Metabolic syndrome” (MetS) is the name for a clustering of risk factors for cardiovascular disease and type 2 diabetes that are of metabolic origin. These include central obesity, elevated plasma glucose, high blood pressure, atherogenic dyslipidemia, a prothrombotic state, and a proinflammatory state. In this article, we provide an overview of the relevant literature with regard to the relationship of Alzheimer's disease with MetS. Accumulating evidence suggests a “vascular hypothesis” to be related to the pathology of Alzheimer's disease. In the light of this evidence, clinician may consider lifestyle interventions toward an early and effective cardiovascular risk-factor management to reduce the cardiometabolic and the cognitive decline risk, while further research of other preventive strategies may be warranted.

This report describes the case of a young man with a large calcification in the right thalamus that was first diagnosed at 9 years of age. Case history reveals specific eating rituals and other obsessive-compulsive personality traits during the patient's childhood and adolescence, fulfilling diagnostic criteria of obsessive-compulsive personality disorder. After a critical life event the patient develops anorexia nervosa. We suggest that our case and further literature provide evidence for an involvement of specific thalamic structures, such as the dorsomedial nucleus, in the development of anorexia nervosa. Furthermore, the treatment of the patient by a combined psychotherapeutic and pharmacotherapeutic approach is described. We focus on the beneficial effect of the atypical antipsychotic olanzapine, which can induce weight gain by an increase of leptin levels.

Dementia is a neuropsychiatric disorder characterized by cognitive impairment and behavioral disturbances. The behavioral and psychological symptoms of dementia (BPSD) are common, contributing to caregiver burden and premature institutionalization. Management of BPSD is complex and often needs recourse to psychotropic drugs. Though widely prescribed, there is a lack of consensus concerning their use, and serious side effects are frequent. This is particularly the case with antidepressant treatment based on the assumption that BPSD is depressive in nature. A better understanding of BPSD etiology could lead to better management strategies. We submit that some BPSD could be the consequence of both dementia and an undiagnosed comorbid bipolar spectrum disorder, or a pre-existing bipolar diathesis pathoplastically altering the clinical expression of dementia. The existence of such a relationship is based on clinical observation, as far as the high frequency of bipolar spectrum disorders in the general population, with a prevalence estimated to be between 5.4% and 8.3%, and the psychopathological similarities between BPSD and mood disorder episodes in bipolar illness. We will review the concept of the bipolar spectrum and explain BPSD before proposing clinical pointers of a possible bipolar spectrum contaminating the phenomenology of dementia, which could lead to the targeted prescription of mood-stabilizing agents in lieu of antidepressant monotherapy. These considerations are of heuristic interest in reconceptualizing the origin of the behavioral manifestations of dementia, with important implications for geriatric practice.

Objective: Understanding variations in disease presentation in men and women is clinically important as differences may reflect biological and sociocultural factors and have implications for prevention and treatment strategies. Few empirical investigations have been performed in kleptomania, particularly with respect to gender-related influences.

Methods: From 2001–2007, 95 adult subjects (n = 27 [28.4%] males) with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-defined kleptomania were assessed on sociodemographics and clinical characteristics, including symptom severity, comorbidity, and functional impairment, to identify gender-related differences.

Results: Men and women showed substantial symptom severity and functional impairment. Compared with affected men, women with kleptomania were more likely to be married (47.1% vs 25.9%; P = .039), have a later age at shoplifting onset (20.9 vs 14 years of age; P = .001), steal household items (P <.001), hoard stolen items (P =.020), and have an eating disorder (P = .017) and less likely to steal electronic goods (P < .001) and have another impulse-control disorder (P = .018).

Conclusion: Kleptomania is similarly associated with significant impairment in women and men. Gender-related differences in clinical features and co-occurring disorders suggest that prevention and treatment strategies incorporate gender considerations.

Today’s therapies must be put in the context of both currently available treatments as well as treatment trials with exciting potential for use in the near future. Current clinical trial methodologies do not allow for clear separation of symptomatic treatments from disease-modifying therapies; it may be unproductive to maintain this distinction given the current range of treatments available. A more currently relevant focus is added value. Therapies should aim to provide added value through incremental benefits above and beyond existing treatments, as well as enduring benefits.

Alzheimer’s disease (AD) treatment guidelines are not used by physicians only. Healthcare payers often make use of these guidelines to delimit coverage. Cost concerns will also impact AD treatments after generic cholinesterase inhibitors are made available; it is widely believed that a great number of patients will switch to generics. Therefore, treatment guidelines must account for the possible adverse effects of switching therapies as well as the desirability of persistent treatment. There are many AD treatment guidelines, among them the American Academy of Neurology (AAN) Management of Dementia Guidelines, which are currently being revised. The Institute for the Study on Aging (ISOA) Management of Alzheimer’s Disease in Managed Care Guideline also presents a different approach for a different audience.

The first step to creating evidence-based best practices guidelines is to determine what is meant by “evidence.” A system of classification exists for examining forms of evidence: Class I evidence is provided by one or more well-designed, randomized, controlled clinical trials, including overviews or meta-analyses of such trials. Class II evidence is provided by well-designed observational studies with concurrent controls; for example, case-control studies that generate hypotheses about epidemiologic associations. Class III evidence is provided by expert opinion, case series, case reports, and studies with historical controls.
