Major depressive disorder is a complex and common mental disease, for which the pathology has not been elucidated. The purpose of this study is to provide knowledge about the importance of mitochondrial dysfunction, dysregulated lipid metabolism and inflammation. Mitochondrial carnitine palmitoyl transferase 1a (CPT1a) is a key molecule involved in lipid metabolism and mutations in CPT1a causing reduced function is hypothesized to have a protective role in the development of depression. Moreover, CPT1a is found to be upregulated in suicide patients with history of depression...

OBJECTIVE: Hardly any studies exist on the duration of major depressive disorder (MDD) and factors that explain variations in episode duration that lack biases. This limits clinical decision-making and leaves patients wondering when they will recover. METHOD: Data were used from the Netherlands Mental Health Survey and Incidence Study-2, a psychiatric epidemiological cohort study among a nationally representative adult population. Respondents with a newly originated depressive episode were selected: 286 MDD and 107 minor depressive disorder (MinDD) cases...

BACKGROUND: The present study was conducted to examine the hypothesis based on our previous studies, that the multiple diagnoses of comorbid anxiety disorders (ADs) and higher interpersonal sensitivity predict treatment-resistant depression (TRD). METHODS: The participants were 199 consecutive outpatients with major depressive disorder (MDD), who were comprehensively diagnosed using the Mini International Neuropsychiatric Interview (MINI). TRD was defined as the failure to achieve remission with two or more adequate antidepressant trials...

BACKGROUND: Although eating disorders (EDs) are common in bipolar disorder (BD), little is known regarding their longitudinal consequences. We assessed prevalence, clinical correlates, and longitudinal depressive severity in BD patients with vs. without EDs. METHODS: Outpatients referred to Stanford University BD Clinic during 2000-2011 were assessed with the Systematic Treatment Enhancement Program for BD (STEP-BD) affective disorders evaluation, and while receiving naturalistic treatment for up to 2 years, were monitored with the STEP-BD clinical monitoring form...

Gabriele Sani, Giulio Perugi, Leonardo Tondo
Lithium preparations have been successfully used to treat bipolar disorder (BD), and remain the best established long-term treatment for the disorder. In fact, lithium is a cornerstone of treatment to minimize the risk of recurrences and improve inter-episodic symptomatology. We reviewed the available evidence for the use of lithium in the treatment of BD, including its efficacy, limitations, and potential benefits also in consideration of the different formulations available. We also overviewed salient comparative aspects regarding the long-term alternative use of anticonvulsants, antidepressants, and antipsychotics in BD patients...

PURPOSE: Depression currently affects 350 million people, and its prevalence among adolescents is 4% to 8%. Adolescents who abandon antidepressant treatment or drop out of clinical trials are less likely to recover or experience a remission of symptoms because they are not being followed up by a medical team. The objective of this study was to analyze the dropout rates of randomized clinical trials of depressed adolescents receiving treatment with antidepressant drugs and the factors associated with nonadherence by summarizing this information in a systematic review and meta-analysis...

Depression is a common mental disorder and a leading cause of disability. At its most severe, it can lead to suicide. Recently, there has been growing interest in the application of natural herbs for the prevention and treatment of depression. In this report, we found that the ginsenoside active component Rg3 has an apparent antidepressant effect. In N-methyl-d-aspartic acid (NMDA)-treated HT22 murine hippocampal neuronal cells, Rg3 recovered proliferation and inhibited apoptosis by altering the cell cycle...

A 60-year-old female was treated for depression with the antidepressant paroxetine for 13 years. The patient had experienced clumsiness and mild rigidity in the left hand, and had agraphia and mild subjective memory complaints for 3 years prior to admission in our hospital. She experienced exacerbated depression that included worsened depressive mood, lowered motivation, and suicidal ideation without precipitating stressful life events for 2 years prior to admission, and although she had continued taking the antidepressant, these symptoms were not ameliorated by increasing the dose of paroxetine...

CONTEXT: Depression, a sustained mood disorder caused by selective diminution of specialized cells in brain is increasing at an alarming rate. It will be the second largest morbid illness by next decade and is the leading cause of suicidal deaths. The available antidepressant medications benefit only a third of its recipients and have many side effects. Hence, it is imperative to search in Ayurveda for leads. AIM: To evaluate Anti- depressant activity of Hiṅgvādi Ghṛta in vivo ...

Rapid cycling bipolar disorder is encountered frequently in clinical practice with a lifetime prevalence of up to 31 %. Besides its association with greater illness severity, increased suicide and comorbidity rates, rapid cycling bipolar disorder has been closely associated with a longer and more complicated course of disease and inadequate treatment response compared to non-rapid cycling bipolar disorder. However rapid cycling does not serve as a stable characteristic of bipolar disorder, though its prevalence increases with illness duration...

Suicide is a major public health problem everywhere in the world and in the WHO European Region suicide accounts for over 120,000 deaths per year. 1. Recognition and diagnosis: An underlying psychiatric disorder is present in up to 90% of people who completed suicide. Comorbidity with depression, anxiety, substance abuse and personality disorders is high. In order to achieve successful prevention of suicidality, adequate diagnostic procedures and appropriate treatment for the underlying disorder are essential...

OBJECTIVE: Smoking prevalence rates are elevated in individuals with schizophrenia spectrum disorders (SSD) compared with the general population, with attendant disproportionate smoking-related morbidity and mortality. Pharmacotherapies that improve abstinence rates in this population are underutilized, partly due to concerns about neuropsychiatric safety, particularly for those with comorbid depression or prior suicide attempt. Prospective assessment of the psychiatric safety profile of varenicline in those with SSD is needed...

BACKGROUND: Conventional antidepressants usually require several weeks to achieve a full clinical response in patients with major depressive disorder, an illness associated with dysregulated circadian rhythms and a high incidence of suicidality. Two rapid-acting antidepressant strategies, low-dose ketamine (KT) and sleep deprivation (SD) therapies, dramatically reduce depressive symptoms within 24 hours in a subset of major depressive disorder patients. However, it is unknown whether they exert their actions through shared regulatory mechanisms...

OBJECTIVE: To explore the prevalence and clinical profile of males and females who develop antidepressant treatment-emergent mania (ATEM). METHOD: From an original sample of 754 patients with BD, we identified ATEM+ cases (n = 75) and ATEM- controls (n = 135) that met stringent criteria. We specifically examined the combinations of clinical factors that best classified males and females as ATEM+ cases. RESULTS: Seventy-five individuals were classified as ATEM+; 87% of ATEM events occurred during antidepressant monotherapy...

BACKGROUND: Decreased binding capacity of SERT in the prefrontal cortex has been observed in both suicide victims and suicide attempters. Moreover, some studies have shown that SERT has a seasonal variation with lower binding capacity in the spring and summer, which coincides with a seasonal peak of suicides. Our aim was to explore whether the season of treatment initiation with antidepressants is associated with suicide or suicide attempt and compare it with the underlying suicide seasonality in the general population...

RATIONALE: Major depressive disorder is a leading cause of suicide and disability. Despite this, current antidepressants provide insufficient efficacy in more than 60% of patients. Most current antidepressants are presynaptic reuptake inhibitors; postsynaptic signal regulation has not received as much attention as potential treatment targets. OBJECTIVES: We examined the effects of disruption of the postsynaptic cyclic nucleotide hydrolyzing enzyme, phosphodiesterase (PDE) 1b, on depressive-like behavior and the effects on PDE1B protein in wild-type (WT) mice following stress...

Publications reporting concentrations of caffeine in postmortem blood were reviewed if the cause of death was attributed to overdosing (poisoning) with drugs. Age and gender of the deceased, the manner of death (accident, suicide or undetermined) and types of co-ingested drugs were evaluated in relation to the concentrations of caffeine in blood (N = 51). The mean age (±SD) of the victims was 39 ± 17.8 years (range 18-84 years) and most were female (N = 31 or 61%). The difference in mean age of males (42 ± 17...
