IMPORTANCE: Depression is frequent in patients with heart failure and is associated with adverse clinical outcomes. Long-term efficacy and safety of selective serotonin reuptake inhibitors in these patients are unknown. OBJECTIVE: To determine whether 24 months of treatment with escitalopram improves mortality, morbidity, and mood in patients with chronic systolic heart failure and depression. DESIGN, SETTING, AND PARTICIPANTS: The Effects of Selective Serotonin Re-Uptake Inhibition on Morbidity, Mortality, and Mood in Depressed Heart Failure Patients (MOOD-HF) study was a double-blind, placebo-controlled randomized clinical trial conducted at 16 tertiary medical centers in Germany...

Possible underlying organic causes of psychiatric symptoms can be overlooked in the clinical setting. It is important to increase awareness amongst psychiatric and neurological professionals with regard to certain inborn errors of metabolism as, in some cases, disease-specific therapies are available that can, for instance, treat underlying metabolic causes. The following article describes the basic pathophysiology, clinical and neurological features, and available diagnostic procedures of six treatable metabolic diseases that are associated with neuropsychiatric symptoms: Wilson's disease, cerebrotendinous xanthomatosis, porphyrias, homocysteinemia, urea cycle disorders, and Niemann-Pick disease type C (NP-C)...

Innate immune activation and inflammation have been posited to play a role in the pathophysiology of both depression and neoplastic growth. Cancer patients experience a threefold higher rate of depression than the general population within the first five years of diagnosis. Chronic depression is associated with increased cancer risk and shortened survival. Although the precise cellular and molecular mechanisms of this bidirectional relationship remain unclear, elevated concentrations of circulating plasma proinflammatory cytokines associated with depression may mediate the neuroendocrine, neural, and immune pathways that account for the relationship...

Metabolic disorders are not well-recognized by psychiatrists as a possible source of secondary psychoses. Inborn errors of metabolism (IEMs) are not frequent. Although their prompt diagnosis may lead to suitable treatments. IEMs are well-known to pediatricians, in particular for their most serious forms, having an early expression most of the time. Recent years discoveries have unveiled later expression forms, and sometimes very discreet first physical signs. There is a growing body of evidence that supports the hypothesis that IEMs can manifest as atypical psychiatric symptoms, even in the absence of clear neurological symptoms...

OBJECTIVE: The vascular depression hypothesis postulates that cerebral small vessel disease (CSVD) leads to depressive symptoms by disruption of brain structures involved in mood regulation. However, longitudinal data on the association between CSVD and depressive symptoms are scarce. The authors investigated the association between CSVD and incident depressive symptoms. METHOD: Longitudinal data were taken from the Age, Gene/Environment Susceptibility-Reykjavik Study of 1,949 participants free of dementia and without baseline depressive symptoms (mean age: 74...

Frailty is increasingly being recognized as a relevant health measure in older populations, associated with an increased risk of adverse health outcomes and care dependency. Because it is generally perceived that people with intellectual disabilities are "old" from age 50 onwards, frailty research in this group might lead to an understanding of factors, contributing to this perception. The development since the 1990s of conceptual and operational definitions of frailty has resulted in different approaches: biological (phenotype), multidimensional, and non-specific deficit accumulation...

Obstructive sleep apnea (OSA) is associated with impairments in cognitive functioning. Although cognitive complaints are related to quality of life, work productivity and health care expenditures, most research and all reviews have focused exclusively on objective cognitive functioning so far. In this systematic review, we assessed the available literature on subjective measures of cognition in adult OSA patients. Concentration complaints were consistently found to be more severe in untreated OSA patients as compared to primary snorers and healthy controls...

OBJECTIVE: To assess the utility of prophylactic administration of antidepressants in preventing a major depressive episode during antiviral treatment for chronic hepatitis C. DATA SOURCES: A computerized literature search was conducted in MEDLINE, PsycINFO, EMBASE, the Cochrane Library, and ClinicalTrials.gov to locate articles published in any language from the earliest available online year until October 2012, using the following phrase and Boolean logic algorithm: "hepatitis and c and (interferon-alpha OR peginterferon OR (pegylated and interferon)) and (depression OR mood) and (prevention OR prophylactic OR prophylaxis OR antidepressant)...

BACKGROUND: Antiviral therapy with interferon-alpha (IFN-α) for hepatitis C virus (HCV) infection is associated with increased risk for depression. AIMS: To identify clinical predictors for IFN-α-induced depression during antiviral therapy for HCV infection. METHOD: Depression (defined with the Montgomery-Åsberg Depression Rating Scale (MADRS)) was evaluated before and during antiviral treatment in 91 people with chronic HCV infection without a history of psychiatric disorders...

Liver failure affects brain function, leading to neurological and psychiatric alterations; such alterations are referred to as hepatic encephalopathy (HE). Early diagnosis of minimal HE reveals an unexpectedly high incidence of mild cognitive impairment and psychomotor slowing in patients with liver cirrhosis - conditions that have serious health, social and economic consequences. The mechanisms responsible for the neurological alterations in HE are beginning to emerge. New therapeutic strategies acting on specific targets in the brain (phosphodiesterase 5, type A GABA receptors, cyclooxygenase and mitogen-activated protein kinase p38) have been shown to restore cognitive and motor function in animal models of chronic HE, and NMDA receptor antagonists have been shown to increase survival in acute liver failure...

Systemic lupus erythematosus (SLE) is a relapsing-remitting autoimmune disease with CNS involvement occurring in up to 75% of patients. However, the frequency of neuropsychiatric manifestations in SLE studies varies widely, depending on the type of manifestations included and the method used for evaluation. CNS involvement may be considered primary if directly related to SLE activity in the CNS or secondary when related to treatment, infections, metabolic abnormalities or other systemic manifestations such as uraemia and hypertension...
