REVIEW
Nobuyoshi Ishii, Takeshi Terao
Lithium therapy is generally accepted as a first-line treatment for bipolar disorder, and it is also identified as one of the best augmenting options for treatment-resistant depression. Furthermore, lithium has been investigated in association with suicide, dementia and aggressiveness. In this review, we examined articles about the effects of very small amounts of lithium in treating suicide, dementia, bipolar disorder and temperament, to assess the present state of trace lithium's effect on mental state. The results indicate that trace lithium may be effective for suicide prevention but randomized, placebo-controlled trials are required to draw a definite conclusion...

BACKGROUND: Few high-quality, large-scale, controlled trials comparing the effectiveness and safety of acupuncture,auricular acupuncture and combined acupuncture treatment for insomnia are available. OBJECTIVE: To carry out a randomised, assessor-blinded, waitlist-controlled trial to test the superiority of combination treatment. METHODS: After in-person and polysomnography screening, 224 subjects (mean age 53.4 years; 75.4% female) with DSM-5 insomnia disorder, who were free from major psychiatric disorders and with sleep-diary-derived sleep efficiency averaged over 1 week of <85%, were randomised to acupuncture alone, acupuncture plus auricular acupuncture (combination treatment), or a waitlist in a 3:3:1 ratio...

Major Depressive Disorder (MDD) is one of the most prevalent psychiatric disorders worldwide. About 20-30% of patients do not respond to the standard psychopharmacological and/or psychotherapeutic interventions. Mounting evidence from neuroimaging studies in MDD patients reveal altered activation patterns in lateral prefrontal brain areas. Successful cognitive behavioral therapy (CBT) is associated with a recovery of these neural alterations. Moreover, it has been demonstrated that transcranial direct current stimulation (tDCS) is capable of influencing prefrontal cortex activity and cognitive functions such as working memory and emotion regulation...

An ambition of depression biomarker research is to augment psychometric and cognitive assessment of clinically relevant phenomena with neural measures. Although such applications have been slow to arrive, we observe a steady evolution of the idea and anticipate emerging technologies with some optimism. To highlight critical themes and innovations in depression biomarker research, we take as our point of reference a specific research narrative. We begin with an early model of frontal-limbic dysfunction, which represents a conceptual shift from localized pathology to understanding symptoms as an emergent property of distributed networks...

OBJECTIVES: Spontaneous orgasm is characterized by a spontaneous onset of orgasm without any preceding sexual or nonsexual trigger. It sheds insight on the mechanisms underlying orgasms and the sexual response cycle in humans. METHODS: We report a male patient of repetitive spontaneous orgasm under trazodone treatment and systematically review the literature on drug-associated spontaneous orgasm (DASO). RESULTS: A total of 25 patients (18 women and 7 men), including our reported case, experienced 27 DASO events...

Organophosphorus compounds, including nerve agents and pesticides, exert their toxicity through irreversible inhibition of acetylcholinesterase (AChE) resulting in an accumulation of acetylcholine and functional impairment of muscarinic and nicotinic acetylcholine receptors. Current therapy comprises oximes to reactivate AChE and atropine to antagonize effects induced by muscarinic acetylcholine receptors. Nicotinic malfunction leading to depression of the central and peripheral respiratory system is not directly treated calling for alternative therapeutic interventions...

In M. sativa cv. Gabès plants treated with 150mM NaCl, the height of the stem is decreased and the internode number, length and diameter are reduced. This depressive effect on growth, but also on photosynthetic activity and water balance, is accompanied by structural changes. In the upper internodes, NaCl treatment increases cambium development, so that the vascular ring is initiated earlier than in controls. In the lower internodes, the number of lignified phloem fibers is increased by NaCl, and their wall thickness is augmented, compared to controls; in the phloem complex, the nacreous layer is enlarged, the number of internal wall ingrowths is increased, but companion cells are damaged...

Elevated kynurenine (Kyn) production from tryptophan (Trp) metabolism is a biomarker of immune dysregulation in depression, but its mechanistic contributions to the behavioral symptoms are poorly defined. In this study, Kyn was shown to be a metabolic regulator of proinflammatory monocytes that orchestrated peripheral immune activation and neuroinflammation in depressive mice. Kyn-induced depressive behavior was paralleled by brain infiltration of proinflammatory monocytes and astrocytic activation. Kyn enhanced chemokine (C-C motif) ligand-2-mediated chemotaxis of monocytes and their proinflammatory capability on cocultured astrocytes in vitro, which involved the activation of aryl hydrocarbon receptor (AhR) signaling...

The action of memantine on N-methyl-D-aspartate (NMDA) glutamatergic receptors and the other pharmacodynamic actions of this drug suggest that it may benefit patients with schizophrenia. Many randomized controlled trials (RCTs) have examined this possibility. These RCTs have been meta-analyzed by at least 2 groups of authors. In one meta-analysis (8 RCTs, pooled N = 448), memantine (20 mg/d for 6-12 weeks) augmentation of antipsychotic drug therapy was found to attenuate the severity of negative symptoms and improve cognitive functioning; in both regards, the effect was large...

Short-term synaptic plasticity (SSP) is a basic mechanism for temporal processing of neural information in synaptic transmission. Facilitation, the fastest component of SSP, has been extensively investigated with regard to Ca2+ signalling and other relevant substances. However, systematic analyses on the slower components of SSP, originated by Magleby and Zengel, have remained stagnant for decades, as few chemicals directly modifying these slower components have been identified. In combination with refined experimental protocols designed to study the stimulation frequency-dependence of SSP and botulinum neurotoxins A and C (BoNT-A and BoNT-C), we investigated SSP of frog neuromuscular transmission to clarify the roles of synaptosomal-associated protein of 25 kDa (SNAP-25) and syntaxin, SNARE proteins exclusively participating in vesicular events including docking, priming and exocytosis...

Major depressive disorder (MDD) is a severe psychiatric syndrome with high prevalence and socioeconomic impact. Current antidepressant treatments are based on the blockade of serotonin (5-hydroxytryptamine, 5-HT) and/or noradrenaline transporters. These drugs show slow onset of clinical action and limited efficacy, partly due to the activation of physiological negative feed-back mechanisms operating through autoreceptors (5-HT1A, 5-HT1B, α2-adrenoceptors) and postsynaptic receptors (e.g., 5-HT3). As a result, clinically-relevant doses of reuptake inhibitors increase extracellular (active) 5-HT concentrations in the midbrain raphe nuclei but not in forebrain, as indicated by rodent microdialysis studies and by PET-scan studies in primate/human brain...

Clinical Practice Guidelines (CPGs) are seen as the gold standard of evidence-based care. Because of their influence, these guidelines can have profound legal and economic effects. Despite their proliferation and influence, the trustworthiness and quality of guidelines have been seriously questioned and they have been implicated as drivers of overtreatment. In the U.S, augmentation with second generation antipsychotics (SGAs) is becoming an increasingly common strategy for treating major depressive disorder (MDD) when initial antidepressant treatment does not result in remission of symptoms...

Mental illnesses like schizophrenia (SCZ) and major depression disorder (MDD) are devastating brain disorders. The SCZ risk gene, disrupted in schizophrenia 1 (DISC1), has been associated with neuropsychiatric conditions. However, little is known regarding the long-lasting impacts on brain metabolism and behavioral outcomes from genetic insults on fetal NPCs during early life. We have established a new mouse model that specifically interrupts DISC1 functions in NPCs in vivo by a dominant-negative DISC1 (DN-DISC1) with a precise temporal and spatial regulation...

RATIONALE: Depressive episodes are the leading cause of mental health-related hospital admissions in Australia, and 44% of those admitted have a previous history of hospitalisations for depression (Admitted patient mental health-related care: (Australian Institute of Health and Welfare Aust Hospital Stat 2011-12, 2013). Despite numerous available antidepressant treatments, many patients do not respond to conventional therapy, having what is called 'treatment resistance' (Fava Biol Psychiatry 53:649-659, 2003)...

Various internalizing risk factors predict, in separate studies, both augmented and reduced cortisol responding to lab-induced stress. Stressor severity appears key: We tested whether heightened trait-like internalizing risk (here, trait rumination) predicts heightened cortisol reactivity under modest objective stress, but conversely predicts reduced reactivity under more robust objective stress. Thus, we hypothesized that trait rumination would interact with a curvilinear (quadratic) function of stress severity to predict cortisol reactivity...

Perinatal depression (PND) affects 15% of women. During the perinatal period both stress- and gonadal hormones fluctuate widely. Putatively, these fluctuations are involved in PND disease mechanisms. The serotonin system is sensitive to such hormone fluctuations, and serotonin reuptake inhibitors (SSRIs) are used to treat PND, although treatment is suboptimal and it is not known at which peripartum time-point SSRI treatment may be most efficacious. In this study, we investigate the effect of the SSRI paroxetine (5mg/kgs...

It has long been known from microneurographic recordings in human subjects that activity of postganglionic sympathetic axons occurs as spontaneous bursts, with muscle sympathetic nerve activity (MSNA) exhibiting strong cardiac rhythmicity via the baroreflex and skin sympathetic nerve activity (SSNA) showing much weaker cardiac modulation. Here we review the firing properties of single sympathetic neurons, obtained using highly selective microelectrodes. Individual vasoconstrictor neurons supplying muscle or skin, or sudomotor neurones supplying sweat glands, always discharge with a low firing probability (~30%) and at very low frequencies (~0...

PURPOSE OF REVIEW: The purpose of this paper is to provide a review of the use of ketamine as an antidepressant for treatment-resistant depression (TRD) in the geriatric population. Available treatment options for late-life treatment-resistant depression are limited and include electroconvulsive therapy and transcranial magnetic stimulation as well as possible pharmacologic augmentation. Ketamine has been shown to be a promising treatment in TRD; however, data regarding the use of ketamine in the elderly includes only five case reports...
