Brain trauma is often associated with severe morbidity and is a major public health concern. Even when injury is mild and no obvious anatomic disruption is seen, many individuals suffer disabling neuropsychological impairments such as memory loss, mood dysfunction, substance abuse, and adjustment disorder. These changes may be related to subtle disruption of neural circuits as well as functional changes at the neurotransmitter level. In particular, there is considerable evidence that dopamine (DA) physiology in the nigrostriatal and mesocorticolimbic pathways might be impaired after traumatic brain injury (TBI)...

BACKGROUND: There has been increasing evidence that chronic low-grade inflammation is associated with mood disorders. However, the findings have been inconsistent because of heterogeneity across studies and methodological limitations. Our aim is to prospectively evaluate the bi-directional associations between inflammatory markers including interleukin (IL)-6, tumor necrosis factor (TNF)-α and high sensitivity C-reactive protein (hsCRP) with mood disorders. METHODS: The sample consisted of 3118 participants (53...

Lithium (Li) is a relevant mood stabilizer metal for the treatment of bipolar disorder (BD), as it protects from both depression and mania and reduces the risk of suicide. However, Lihas some clinical concerns as a narrow therapeutic index requiring routine monitoring of the serum level. The present study was designed to analyze the cardio-toxic side effect of Li and the ability of grape seed and skin extract (GSSE) to protect the heart against such toxicity. After 30days of exposure to Li (0, 2, 5 and 100mg/kg bw) and prevention with GSSE (4000mg/kg bw), rats were killed by decapitation and their heart processed for Li-induced oxidative stress...

Neuroactive steroids (NASs) are naturally occurring steroids, which are synthesized centrally as de novo from cholesterol and are classified as pregnane, androstane, and sulfated neurosteroids (NSs). NASs modulate many processes via interacting with gamma-aminobutyric acid (GABA), N-methyl-d-aspartate, serotonin, voltage-gated calcium channels, voltage-dependent anion channels, α-adrenoreceptors, X-receptors of the liver, transient receptor potential channels, microtubule-associated protein 2, neurotrophin nerve growth factor, and σ1 receptors...

BACKGROUND: Treatment of medical patients with the inflammatory cytokine, interferon-α (IFN-α), is frequently associated with the development of clinical depressive symptomatology. Several important biological correlates of the effect of IFN-α on mood have been described, but the neuropsychological changes associated with IFN-α treatment are largely unexplored. The aim of the present preliminary study was to assess the effect of IFN-α on measures of emotional processing. METHOD: We measured changes in emotional processing over 6-8 weeks in 17 patients receiving IFN-α as part of their treatment for hepatitis C virus infection...

Depression is a mental disorder associated with environmental, genetic and psychological factors. Recent studies indicate that chronic neuro-inflammation may affect brain physiology and alter mood and behavior. Consumption of a high-fat diet leads to obesity and chronic systemic inflammation. The gut microbiota mediates many effects of a high-fat diet on human physiology and may also influence the mood and behavior of the host. We review here recent studies suggesting the existence of a link between obesity, the gut microbiota and depression, focusing on the mechanisms underlying the effects of a high-fat diet on chronic inflammation and brain physiology...

BACKGROUND: Light at night creates a conflicting signal to the biological clock and disrupts circadian physiology. In rodents, light at night increases the risk to develop mood disorders, overweight, disrupted energy metabolism, immune dysfunction and cancer. We hypothesized that constant light (LL) in rats may facilitate tumor growth via disrupted metabolism and increased inflammatory response in the host, inducing a propitious microenvironment for tumor cells. METHODS: Male Wistar rats were exposed to LL or a regular light-dark cycle (LD) for 5 weeks...

OBJECTIVE: Chronic, low-level inflammation is associated with symptomatic bipolar disorder (BD) and with chronic insomnia. Disrupted sleep is a feature of episodes of both mania and depression. We examined the effect of neopterin, a marker of cellular immune activation, and kynurenine (KYN), an inflammatory byproduct of the serotonin pathway, on the association between total sleep time and depression severity in BD. METHOD: Twenty-one symptomatic BD participants and 28 healthy controls (HC) were recruited and followed during usual clinical care...

Neuro-inflammation has been shown to play a critical role in the development of depression. Beta-hydroxybutyrate (BHB) is a ketone body and has recently been reported to exert anti-inflammatory effects via inhibition of NLRP3 inflammasome. Here, we investigated the potential antidepressant and anti-inflammatory effects of BHB on rats exposed to acute and chronic stress. We examined the influence of repeated BHB administration on depressive and anxiety behaviors in a rodent model of chronic unpredictable stress (CUS)...

BACKGROUND: Treatments for depression in bipolar disorder (BD) are far less well developed than for unipolar major depressive disorder. Several innovative and experimental approaches have been emerging recently, including use of the dissociative anesthetic ketamine and other antagonists of central NMDA glutamate receptors, as well as unsaturated fatty acids, anti-inflammatory agents, and possibly probiotic methods. METHODS: We reviewed relevant reports from the past decade...

Epilepsy is one of the most complex neurological disorders whose study requires a broad knowledge of neurology and neuroscience. It comprises a diverse group of neurological disorders that share the central feature of spontaneous recurrent seizures, and are often accompanied by cognitive deficits and mood disorder. This condition is one of the most common neurological disorders. Until recently, alterations of neuronal activities had been the focus of epilepsy research. This neurocentric emphasis did not address issues that arise in more complex models of epileptogenesis...

Neuroprogression is a term used to describe worsening psychopathology, poor treatment response, and declining cognitive and functional outcomes among patients with chronic mental disorders. Chronic inflammatory activation and glutamate-mediated excitotoxicity are two key etiological factors implicated in the development of neuroprogression. In this chapter, we hypothesize that the association between chronic inflammatory activation, neuroprogression, and glutamate dysregulation might be mediated by glial dysfunction...

Treatment refractoriness remains one of the biggest challenges in the field of bipolar disorder (BD) as treatments are often suboptimal or unsatisfactory. Recent evidence points towards a potential link between the progressively evolving nature of BD, increased inflammation, and reduced treatment response. There are several medications and other somatic treatments available, but remission rates are low, and medication compliance is still problematic. Psychotherapeutic techniques appear to be promising in several disease states and in relapse prevention, but additional research is needed to determine who will benefit from what strategy the most...

BACKGROUND: Depression and anxiety are two common mood disorders that are both linked to systemic inflammation. Increased white blood cell (WBC) count and red cell distribution width (RDW) are associated with negative clinical outcomes in a wide variety of pathological conditions. WBC is a non-specific inflammatory marker and RDW is also strongly related to other inflammatory markers. Therefore, we proposed that there might be an association between these hematological inflammatory markers and depression/anxiety symptoms...

Background: Late Onset Bipolar Disorder (LOBD) is the development of Bipolar Disorder (BD) at an age above 50 years old. It is often difficult to differentiate from other aging dementias, such as Alzheimer's Disease (AD), because they share cognitive and behavioral impairment symptoms. Objectives: We look for WM tract voxel clusters showing significant differences when comparing of AD vs. LOBD, and its correlations with systemic blood plasma biomarkers (inflammatory, neurotrophic factors, and oxidative stress)...

The goal of this review is to summarize studies in which concentrations of circulating endocannabinoids in humans have been examined in relationship to physiological measurements and pathological status. The roles of endocannabinoids in the regulation of energy intake and storage have been well studied and the data obtained consistently support the hypothesis that endocannabinoid signaling is associated with increased consumption and storage of energy. Physical exercise mobilizes endocannabinoids, which could contribute to refilling of energy stores and also to the analgesic and mood-elevating effects of exercise...

BACKGROUND: Although inflammatory cytokines are established biomarkers of mood disorders, their molecular mechanism is not known. We hypothesized that circulating mitochondrial DNA (mtDNA) contributes to inflammation and could be used as biomarkers. We investigated if circulating mtDNA level is associated with inflammatory cytokines and can be used as a biomarker of mood disorders. METHODS: Plasma mtDNA concentration was measured with real-time quantitative PCR targeting two regions of the mtDNA and plasma levels of four cytokines (GM-CSF, IL-2, IL-4, and IL-6) were measured with a multiplex immunoassay method in 109 patients with major depressive disorder (MDD)...

REVIEW
Shih-Jen Tsai
A high level of Interleukin-1beta (IL1B), a key mediator of inflammation, is expressed in the brain, particularly in the hippocampus, which plays a pivotal role in memory and mood regulation. In the brain, IL1B exerts a myriad of effects such as neuronal proliferation, differentiation, apoptosis, and long-term potentiation. Considering its pleiotropic effects in the brain, IL1B has been implicated in the pathogenesis of various psychiatric disorders as well as cognitive function in normal individuals. Thus, IL1B has been considered a candidate gene for the study of psychiatric diseases as well as brain function in normal individuals...
