The bipolar spectrum is a broader concept, which questions the strict dichotomous categorical division of erstwhile manic-depressive illness into two discrete categories viz. bipolar disorder and major depressive disorder, thereby overlooking a wide 'spectrum' of patients which lie 'in between' the two extremes. The presence of underlying bipolar 'spectrum' or 'soft bipolarity' often goes undetected in patients presenting with major depression. This sub-group of patients may not stabilize with indiscriminate use of anti-depressant drugs, and without proper management, it may be associated with continued non-responsive symptoms, increased suicidality and poorer prognosis...

Although the brains of patients with schizophrenia and bipolar disorder exhibit decreased brain pH relative to those of healthy controls upon postmortem examination, it remains controversial whether this finding reflects a primary feature of the diseases or is a result of confounding factors such as medication and agonal state. To date, systematic investigation of brain pH has not been undertaken using animal models, which can be studied without confounds inherent in human studies. In the present study, we first reevaluated the pH of the postmortem brains of patients with schizophrenia and bipolar disorder by conducting a meta-analysis of existing datasets from ten studies...

Around the world, psychiatrists are in exceptionally short supply. The majority of mental health treatment is delivered in primary care. In the United States, the Collaborative Care Model (CCM) addresses the shortfall of psychiatrists by providing indirect consultation in primary care. A Cochrane meta-analysis affirms the efficacy this model for depression and anxiety. However, our experience with the CCM suggests that most patients referred for consultation have problems far more complex than simple depression and anxiety...

Many neuropsychiatric disorders show localized dysfunction in specific cortical regions. The mechanisms underlying such region-specific vulnerabilities are unknown. Post-mortem analyses have demonstrated a selective reduction in the expression of parvalbumin (PV) in GABAergic interneurons in the frontal rather than the sensory cortex of patients with neuropsychiatric disorders such as schizophrenia, autism spectrum disorders, and bipolar disorders. PV neurons are surrounded by perineuronal nets (PNNs), and are protected from oxidative stress...

Altered synaptic function has been associated with neurological and psychiatric conditions including intellectual disability, schizophrenia and autism spectrum disorder (ASD). Amongst the recently discovered synaptic proteins is p140Cap, an adaptor that localizes at dendritic spines and regulates their maturation and physiology. We recently showed that p140Cap knockout mice have cognitive deficits, impaired long-term potentiation (LTP) and long-term depression (LTD), and immature, filopodia-like dendritic spines...

In recent years an increasing number of studies focus on the issue of early diagnosis and intervention. At the same time, a large number of special service units for early psychosis have been established around the world especially in Australia, USA, UK, Germany etc. Recently, similar units operate in Greece also. The Diagnostic Manual of Mental Disorders of the American Psychiatric Association in its latest edition in 2013 (DSM-5), introduced the category "Attenuated Psychosis Syndrome" (APS) for people with early psychotic experiences in the section: "Conditions for further study '...

The personal, social and economic burden of post-traumatic stress disorder (PTSD) is high and therapeutic approaches are only partially effective. Therefore, there is an urgent need to understand the cellular and molecular alterations in PTSD brains in order to design more effective treatment strategies. Although brain imaging strategies have considerably improved our understanding of PTSD, these strategies cannot identify molecular and cellular changes. Post-mortem examination of the brain is a crucial strategy to advance our understanding of the underlying neuropathology, neurochemistry and molecular pathways of PTSD...

Importance: Early identification of individuals at high risk for the onset of bipolar spectrum disorder (BPSD) is key from both a clinical and research perspective. While previous work has identified the presence of a bipolar prodrome, the predictive implications for the individual have not been assessed, to date. Objective: To build a risk calculator to predict the 5-year onset of BPSD in youth at familial risk for BPSD. Design, Setting, and Participants: The Pittsburgh Bipolar Offspring Study is an ongoing community-based longitudinal cohort investigation of offspring of parents with bipolar I or II (and community controls), recruited between November 2001 and July 2007, with a median follow-up period of more than 9 years...

Several studies highlight a key involvement of endocannabinoid (EC) system in autism pathophysiology. The EC system is a complex network of lipid signaling pathways comprised of arachidonic acid-derived compounds (anandamide, AEA) and 2-arachidonoyl glycerol (2-AG), their G-protein-coupled receptors (cannabinoid receptors CB1 and CB2) and the associated enzymes. In addition to autism, the EC system is also involved in several other psychiatric disorders (i.e., anxiety, major depression, bipolar disorder and schizophrenia)...

Bipolar disorder (BD) spectrum and alcohol use disorders (AUDs) commonly occur together. Comorbidity between the two conditions predisposes patients to elevated risks of adverse outcomes, including hospitalization and suicide, compared with either condition alone. Despite the consistent relationship observed between BD and AUD, the underlying cause remains incompletely characterized. Few trials conducted have been able to identify promising interventions for patients with these disease states. The antipsychotic quetiapine has been evaluated most commonly as a therapeutic agent for patients with BD and AUD followed by naltrexone and acamprosate...

BACKGROUND: Bipolar disorders are ranked amongst the top ten causes of global disability and cause high health care costs. Previous studies have showed that mood stabilizing drug therapy combined with psychological treatments lead to significantly fewer relapses and a reduction in hospitalization rates. However, there is a wide spectrum of psychosocial intervention methods for individuals and groups which have been insufficiently examined on a scientific basis. METHODS: Studies published between 2003 and 2015 on different types of adjuvant psychosocial group interventions in the MESH database were reviewed and evaluated for their efficacy on patients with bipolar disorder related to the relapse ratio by a meta-analysis...

Individuals with bipolar spectrum disorders experience higher morbidity and mortality rates relative to the general population because of increased commission of dangerous behaviors. Despite this impact, little is known about the overall rates of risk-taking behaviors in patients currently being treated for such illness. This study examined the frequency of a variety of risk-taking behaviors in 100 adults with bipolar spectrum disorders in an active outpatient psychiatric treatment. It was found that 70% of individuals assessed reported at least one risk-taking behavior over the preceding 7 days...

Early life stress has been shown to exert profound short- and long-term effects on human physiology both in the central nervous system and peripherally. Early life stress has demonstrated clear association with many psychiatric disorders including major depression, posttraumatic stress disorder, and bipolar disorder. The Diagnostic and Statistics Manuel of Mental Disorders (DSM) diagnostic categorical system has served as a necessary framework for clinical service, delivery, and research, however has not been completely matching the neurobiological research perspective...
