Abstract
Second messenger systems, like the cyclic nucleotide, glycogen synthase kinase-3β, phosphoinositide, and arachidonic acid cascades, are involved in bipolar disorder (BD). We investigated their role on the development of novel therapeutic drugs using second messenger mechanisms. PubMed search and narrative review. We used all relevant keywords for each second messenger cascade combining it with BD and related terms and combined all with novel/innovative treatments/drugs. Our search produced 31 papers most were reviews, and focussed on the PI3K/AKT-GSK-3β/Nrf2-NF-ĸB pathways. Only two human randomized clinical trials were identified, of ebselen, an antioxidant, and celecoxib, a cyclooxygenase-2 inhibitor, both with poor unsatisfactory results. Despite the fact that all second messenger systems are involved in the pathophysiology of BD, there are few experiments with novel drugs using these mechanisms. These mechanisms are a neglected and potentially major opportunity to transform the treatment of bipolar illness.

Abstract
Bipolar spectrum disorders carry a significant public health burden. Disproportionately high rates of suicide, incarceration, and comorbid medical conditions necessitate an extraordinary focus on understanding the intricacies of this disease. Elucidating granular, intracellular details seems to be a necessary preamble to advancing promising therapeutic opportunities. In this chapter, we review a wide range of intracellular mechanisms including mitochondrial energetics, calcium signaling, neuroinflammation, the microbiome, neurotransmitter metabolism, glycogen synthase kinase 3-beta (GSK3β), protein kinase C (PKC) and diacylglycerol (DAG), and neurotrophins (especially BDNF), as well as the glutamatergic, dopaminergic, purinergic, and neurohormonal systems. Owing to the relative lack of understanding and effective therapeutic options compared to the rest of the spectrum, special attention is paid in the chapter to the latest developments in bipolar depression. Likewise, from a therapeutic standpoint, special attention should be paid to the pervasive mechanistic actions of lithium as a means of amalgamating numerous, disparate cascades into a digestible cognitive topology.

Add-on memantine may improve cognitive functions and attenuate inflammation in middle- to old-aged bipolar II disorder patients. J Affect Disord 2021; 279:229-238. [PMID: 33069121 DOI: 10.1016/j.jad.2020.10.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Revised: 09/03/2020] [Accepted: 10/01/2020] [Indexed: 11/17/2022]
Abstract
OBJECTIVES Chronic inflammation and neuroprogression underlie bipolar disorder (BP) and associated cognitive deficits. Memantine (MM) exerts neuroprotective effects by reducing neuroinflammation. Therefore, we investigated whether add-on low-dose MM (5 mg/day) in BP-II patients may improve cognition and inflammation. METHODS We combined two 12-week randomized, double-blind, placebo-controlled studies (NCT01188148 and NCT03039842) for analysis. Each participant was allocated to the MM or placebo group. Symptom severity, neuropsychological tests, and the cytokine plasma levels [tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), interleukin-8 (IL-8), transforming growth factor-β1 (TGF-β1), and brain-derived neurotrophic factor (BDNF)] were evaluated at baseline and endpoint. A subgroup analysis of middle- to old-aged BP-II patients was also performed. RESULTS We recruited 155 BP-II patients (23 of which were middle- to old-aged) for the MM group and 170 patients (20 of which were middle- to old-aged) for the placebo group. Add-on MM did not result in significant improvements in cognitive functions in all BP-II patients, but a group difference in TNF-α levels was found in the MM group (P=0.04). Specifically, in middle- to old-aged BP-II patients, there was a significant time and group interaction effect on omission T-scores, hit reaction time T-scores, and hit reaction time standard error T-scores on continuous performance tests (CPTs) in the MM group (P=0.007, 0.02, and 0.01, respectively), and a decrease in plasma TNF-α levels (P=0.04). LIMITATIONS The sample size of middle- to old-aged BP-II patients were limited. CONCLUSION Add-on MM may attenuate inflammation in BP-II and improve cognition in middle- to old-aged BP-II patients.

Abstract
BACKGROUND Resistant bipolar disorder is a major mental health problem related to significant disability and overall cost. The aim of the current study was to perform a systematic review of the literature concerning (1) the definition of treatment resistance in bipolar disorder, (2) its clinical and (3) neurobiological correlates, and (4) the evidence-based treatment options for treatment-resistant bipolar disorder and for eventually developing guidelines for the treatment of this condition. MATERIALS AND METHODS The PRISMA method was used to identify all published papers relevant to the definition of treatment resistance in bipolar disorder and the associated evidence-based treatment options. The MEDLINE was searched to April 22, 2018. RESULTS Criteria were developed for the identification of resistance in bipolar disorder concerning all phases. The search of the literature identified all published studies concerning treatment options. The data were classified according to strength, and separate guidelines regarding resistant acute mania, acute bipolar depression, and the maintenance phase were developed. DISCUSSION The definition of resistance in bipolar disorder is by itself difficult due to the complexity of the clinical picture, course, and treatment options. The current guidelines are the first, to our knowledge, developed specifically for the treatment of resistant bipolar disorder patients, and they also include an operationalized definition of treatment resistance. They were based on a thorough and deep search of the literature and utilize as much as possible an evidence-based approach.

Abstract
Around 300 million individuals are affected by major depressive disorder (MDD) in the world. Despite this high number of affected individuals, more than 50% of patients do not respond to antidepressants approved to treat MDD. Patients with MDD that do not respond to 2 or more first-line antidepressant treatments are considered to have treatment-resistant depression (TRD). Animal models of depression are important tools to better understand the pathophysiology of MDD as well as to help in the development of novel and fast antidepressants for TRD patients. This review will emphasize some discovery strategies for TRD from studies on animal models, including, antagonists of N-methyl-D-aspartate (NMDA) receptor (ketamine and memantine), electroconvulsive therapy (ECT), lithium, minocycline, quetiapine, and deep brain stimulation. Animal models of depression are not sufficient to represent all the traits of TRD, but they greatly aid in understanding the mechanism by which therapies that work for TRD exert antidepressant effects. Interestingly, these innovative therapies have mechanisms of action different from those of classic antidepressants. These effects are mainly related to the regulation of neurotransmitter activity, including general glutamate and increased connectivity, synaptic capacity, and neuroplasticity.

Abstract
Background: Mania seems to be associated with an increased dopamine (DA) transmission. Antidepressant treatments can induce mania in humans and potentiated DA transmission in animals, by sensitizing DA D2 receptors in the mesolimbic system. We have suggested that the sensitization of D2 receptors may be responsible of antidepressant-induced mania. This review aims to report the experimental evidence that led to the hypothesis that antidepressant-induced DA receptors dysregulation can be considered an animal model of bipolar disorder. Methods: We reviewed papers reporting preclinical and clinical studies on the role of DA in the mechanism of action of antidepressant treatments and in the patho-physiology of mood disorders. Results: A number of preclinical and clinical evidence suggests that mania could be associated with an increased DA activity, while a reduced function of this neurotransmission might underlie depression. Chronic treatment with imipramine induces a sensitization of DA D2 receptors in the mesolimbic system, followed, after drug discontinuation, by a reduced sensitivity associated with an increased immobility time in forced swimming test of depression (FST). Blockade of glutamate NMDA receptors by memantine administration prevents the imipramine effect on DA receptors sensitivity and on the FST. Conclusion: We suggest that chronic treatment with antidepressants induces a behavioural syndrome that mimics mania (the sensitization of DA receptors), followed by depression (desensitization of DA receptors and increased immobility time in the FST), i.e. an animal model of bipolar disorder. Moreover the observation that memantine prevents the “bipolar-like” behavior, suggests that the drug may have an antimanic and mood stabilizing effect. Preliminary clinical observations support this hypothesis.

Abstract
Memantine, an N-methyl-d-aspartate receptor antagonist, is a well-established treatment option for moderate-to-severe cognitive impairment related to Alzheimer disease. Recently, growing evidence has indicated memantine might also be effective in treatment of affective disorders. The common drug-induced adverse events of memantine include confusion, dizziness, drowsiness, headache, insomnia, and agitation. Herein, we presented a case of a 73-year-old female patient with vascular neurocognitive disorder, who developed a manic episode after taking memantine.

Abstract
INTRODUCTION Treatment of patients suffering from major depression could be highly challenging for psychiatrists. Intractability as well as relapse is commonly seen among these patients, leading to functional impairment and poor quality of life. The present review discusses some of the novel investigational drugs that are under pre-clinical or clinical phases in the treatment of major depression. Areas covered: Molecules belonging to different classes such as triple reuptake inhibitors, opioid receptors, ionotropic and metabotropic glutamate receptors, and neurotrophin in the treatment of major depression are covered in this article. Expert opinion: Although the historical discovery of earlier antidepressant molecules (iproniazid and imipramine) is through serendipitous discovery, the present research focuses on discovering novel molecules based on our current pathophysiological knowledge of the disease condition. The fast-acting antidepressant property of N-methyl-d-aspartate (NMDA) receptor molecules, including ketamine is an exciting area of research. Other drug molecules such as amitifadine (triple reuptake inhibitor), ALKS-5461 (kappa receptor antagonist and mu opioidergic receptor agonist), rapastinel (NMDA glutamatergic receptor modulator) are under Phase-III clinical trials and could be approved in the near future for the treatment of major depression.

Abstract
AIM The aim of this updated meta-analysis was to further assess the effectiveness of cognitive behavioral therapy (CBT) in treating bipolar disorder (BD). METHODS We carried out a literature search on PubMed, Embase, and the Cochrane Library up to October 2015. We calculated the pooled relative risk of relapse rate and standard mean difference (SMD) of mean change (data at a follow-up time-point - baseline) of the Beck Depression Inventory, Beck Hopelessness Scale, Hamilton Rating Scale for Depression, Young Mania Rating Scale (YMRS) and Mania Rating Scale scores with their 95% confidence interval (95%CI). Subgroup analyses based on follow-up time were performed. RESULTS Nine randomized controlled trials with 520 bipolar I or II disorder patients were reanalyzed. Overall analysis showed that CBT did not significantly reduce the relapse rate of BD or improve the level of depression. However, significant efficacy of CBT in improving severity of mania was proved based on the YMRS (SMD = -0.54, 95%CI, -1.03 to -0.06, P = 0.03) but not based on MRS. Subgroup analyses showed that CBT had short-term efficacy in reducing relapse rate of BD (at 6 months' follow-up: relative risk = 0.49, 95%CI: 0.29-0.81, P = 0.006) and improving severity of mania based on YMRS score (post-treatment: SMD = -0.30, 95%CI, -0.59 to -0.01, P = 0.04). CONCLUSION Short-term efficacy of CBT in reducing relapse rate of BD and improving the severity of mania was proved. But these effects could be weakened by time. In addition, there was no effect of CBT on level of depression in BD.

Abstract
Bipolar disorder is prevalent, with high risks of disability, substance abuse and premature
mortality. Treatment responses typically are incomplete, especially for depressive components, so that
many cases can be considered “treatment resistant.” We reviewed reports on experimental treatments
for such patients: there is a striking paucity of such research, mainly involving small incompletely
controlled trials of add-on treatment, and findings remain preliminary. Encouraging results have been reported by adding
aripiprazole, bupropion, clozapine, ketamine, memantine, pramipexole, pregabalin, and perhaps tri-iodothyronine in
resistant manic or depressive phases. The urgency of incomplete responses in such a severe illness underscores the need
for more systematic, simpler, and better controlled studies in more homogeneous samples of patients.

Abstract
Obsessive-compulsive disorder (OCD) is one of the most common comorbidities in bipolar disorder (BD). Clinicians often get perplexed in making treatment decisions when encountering comorbid OCD and BD as treatment of OCD by pharmacotherapy may induce or exacerbate mood instability and psychotherapeutic approaches for OCD may not be feasible in acute manic or depressive state of BD. In this study, we reviewed literature, whether existing guideline-based treatments of BD may be effective in OCD and whether newer agents will be of use for treating this comorbidity. We could find that treatment of such comorbid disorder is largely understudied. Adjuvant topiramate or olanzapine- selective serotonin reuptake inhibitor/clomipramine combination along with mood stabilizer is found to be effective for treating OCD in BD. Use of other conventional pharmacological agents and psychotherapy for treating comorbid OCD in BD lacks evidence and is limited to case reports. Our review also highlights the need for further studies regarding the treatment strategies in this highly prevalent comorbid disorder.

Abstract
AIM: To evaluate antidepressant-like effect of memantine in a rat model.
METHODS: Male Wistar rats were treated intraperitoneally with either vehicle, memantine (10 mg/kg) or imipramine (20 mg/kg), for 3 wk. Twenty-four hour after the last treatment animals were challenged with quinpirole (0.3 mg/kg s.c.) and tested for motor activity. After 1 h habituation to the motility cages, the motor response was recorded for the following 45-min and the data were collected in 5-min time bins.
RESULTS: As expected, chronic treatment with imipramine potentiated the locomotor stimulant effect of quinpirole. On the contrary, chronic memantine administration failed to induce the behavioral supersensitivity to the dopamine agonist.
CONCLUSION: The results show that memantine, at variance with antidepressant treatments, fails to induce dopaminergic behavioral supersensitivity. This observation is consistent with the results of preclinical and clinical studies suggesting that memantine does not have an acute antidepressant action but does have an antimanic and mood-stabilizing effect.

Abstract
The high prevalence of comorbidity between bipolar disorder (BD) and other medical conditions, including autoimmune diseases, supports the hypothesis of the nature of BD as a biological illness category. Hence, an immune dysregulation process may play an important role in the development of at least certain subtypes of BD. Increasing evidence also suggests that the N-methyl-d-aspartate receptor (NMDAR) may be relevant in the pathophysiology of BD. A possible key mechanism underlying the physiopathology of certain autoimmune diseases that may present with affective symptoms might be the production of anti-NMDAR auto-antibodies (auto-Abs). The best characterized autoimmune anti-NMDAR disease is the anti-NMDAR encephalitis. It has been found that 4% of these patients present isolated, mostly affective, psychiatric manifestations during their illness. An interesting suggestion emerged from this overview is that the same mechanisms that trigger affective symptoms in patients with increased anti-NMDAR auto-Abs levels could be involved in the physiopathology of at least a subgroup of BD. Future studies are needed to characterize the relationship between anti-NMDAR auto-Abs and BD.

Abstract
A great deal of evidence suggests that virtually all antidepressant treatments induce a dopaminergic behavioral supersensitivity. We have suggested that this effect may play a key role not only in the antidepressant effect of these treatments, but also in their ability to induce a switch from depression to mania. In 2003-4 we found that the sensitization of dopamine receptors induced by imipramine is followed, after imipramine withdrawal, by a desensitization of these receptors associated with a depressive-like behavior assessed in the forced swimming test. The dopamine receptor sensitization can be prevented by MK-801, an NMDA receptor antagonist, but not by currently used mood stabilizers (lithium, carbamazepine, valproate). These observations led us to suggest - and later confirm - with preliminary clinical observations that memantine may have an acute antimanic and a long-lasting mood-stabilizing effect in treatment-resistant bipolar disorder patients. Here we present data showing that memantine prevents not only the dopamine receptor sensitization induced by imipramine, as observed with MK-801, but also the ensuing desensitization and the associated depressive-like behaviorq observed after antidepressant withdrawal.

Abstract
UNLABELLED We review preclinical and clinical evidences strongly suggesting that memantine, an old drug currently approved for Alzheimer's dementia, is an effective treatment for acute mania and for the prevention of manic/hypomanic and depressive recurrences of manic-depressive illness. Lithium remains the first line for the treatment and prophylaxis of bipolar disorders, but currently available treatment alternatives for lithium resistant patients are of limited and/or questionable efficacy. Thus, research and development of more effective mood stabilizer drugs is a leading challenge for modern psychopharmacology. We have demonstrated that 21 d administration of imipramine causes a behavioural syndrome similar to a cycle of bipolar disorder, i.e., a mania followed by a depression, in rats. Indeed, such treatment causes a behavioural supersensitivity to dopamine D2 receptor agonists associated with an increase sexual activity and aggressivity (mania). The dopamine receptor sensitization is followed, after imipramine discontinuation, by an opposite phenomenon (dopamine receptor desensitization) and an increased immobility time (depression) in the forced swimming test of depression. Memantine blocks the development of the supersensitivity and the ensuing desensitization associated with the depressive like behavior. On the basis of these observations we have suggested the use of memantine in the treatment of mania and in the prophylaxis of bipolar disorders. To test this hypothesis we performed several naturalistic studies that showed an acute antimanic effect and a long-lasting and progressive mood-stabilizing action (at least 3 years), without clinically relevant side effects. To confirm the observations of our naturalistic trials we are now performing a randomized controlled clinical trial. Finally we described the studies reporting the efficacy of memantine in manic-like symptoms occurring in psychiatric disorders other than bipolar. LIMITATIONS A randomized controlled clinical trial is needed to confirm our naturalistic observations. CONCLUSION We believe that this review presents enough pharmacological and clinical information to consider the administration of memantine in the treatment of bipolar disorders that no respond to standard mood stabilizers.

Abstract
OBJECTIVE To report a case of mania associated with the titration of donepezil in an elderly patient. SETTING A 400-bed academic acute care psychiatric facility. CASE SUMMARY A 70-year-old male with a history of paranoid schizophrenia, alcohol dependence, and mild cognitive impairment was admitted after concerns that he was responding to internal stimuli and exhibited increased disorganization. The patient was initiated on quetiapine, titrated to 500 mg at bedtime, to address disorganization, hallucinations, and poor sleep. After improvement of psychotic symptoms and assessment of cognitive function, donepezil 5 mg daily was initiated and titrated to 10 mg daily after two weeks. Days following the increase of donepezil to 10 mg daily, the patient exhibited symptoms of mania and became hyperverbal with elevated mood and agitation. A decreased need for sleep with an increase in cleaning activities throughout the day was noted. Donepezil was suspected to have induced the new symptoms and was discontinued. Following discontinuation, the manic symptoms completely resolved over a two-week period. CONCLUSION The titration of donepezil was associated with the onset of mania. Previous trials involving off-label donepezil use in patients with bipolar disorder, but not schizophrenia, have reported the development of manic symptoms. Although rare, there is mounting evidence that donepezil is associated with the emergence of mania. Clinicians should be aware of this potential side effect in all patients treated with donepezil.

Abstract
Mood disorders such as major depressive disorder and bipolar disorder are chronic and recurrent illnesses that cause significant disability and affect approximately 350 million people worldwide. Currently available biogenic amine treatments provide relief for many and yet fail to ameliorate symptoms for others, highlighting the need to diversify the search for new therapeutic strategies. Here we present recent evidence implicating the role of N-methyl-D-aspartate receptor (NMDAR) signaling in the pathophysiology of mood disorders. The possible role of NMDARs in mood disorders has been supported by evidence demonstrating that: (i) both BPD and MDD are characterized by altered levels of central excitatory neurotransmitters; (ii) NMDAR expression, distribution, and function are atypical in patients with mood disorders; (iii) NMDAR modulators show positive therapeutic effects in BPD and MDD patients; and (iv) conventional antidepressants/mood stabilizers can modulate NMDAR function. Taken together, this evidence suggests the NMDAR system holds considerable promise as a therapeutic target for developing next generation drugs that may provide more rapid onset relief of symptoms. Identifying the subcircuits involved in mood and elucidating the role of NMDARs subtypes in specific brain circuits would constitute an important step toward the development of more effective therapies with fewer side effects.

Abstract
Memantine is a non-competitive N-methyl-d-asparate (NMDA) receptor antagonist with a mood-stabilizing effect. We investigated whether using valproic acid (VPA) plus add-on memantine to treat bipolar II disorder (BP-II) is more effective than using VPA alone (VPA + Pbo). We also evaluated, in BP-II patients, the association between the brain-derived neurotrophic factor (BDNF) Val66Met polymorphism with treatment response to VPA + add-on memantine and to VPA + Pbo. In this randomized, double-blind, controlled 12 wk study, BP-II patients undergoing regular VPA treatments were randomly assigned to a group: VPA + Memantine (5 mg/day) (n = 115) or VPA + Pbo (n = 117). The Hamilton Depression Rating Scale (HDRS) and Young Mania Rating Scale (YMRS) were used to evaluate clinical response during week 0, 1, 2, 4, 8 and 12. The genotypes of the BDNF Val66Met polymorphisms were determined using polymerase chain reactions plus restriction fragment length polymorphism analysis. To adjust within-subject dependence over repeated assessments, multiple linear regression with generalized estimating equation methods was used to analyze the effects of the BDNF Val66Met polymorphism on the clinical performance of memantine. Both groups showed significantly decreased YMRS and HDRS scores after 12 wk of treatment; the differences between groups were non-significant. When stratified by the BDNF Val66Met genotypes, significantly greater decreases in HDRS scores were found in the VPA + memantine group in patients with the Val Met genotype (p = 0.004). We conclude that the BDNF Val66Met polymorphism influenced responses to add-on memantine by decreasing depressive symptoms in patients with BP-II.

Abstract
Memantine and other glutamatergic agents have been currently investigated in some off-label indications due to glutamatergic involvement in several psychoneurological disorders. We assumed that memantine similarly to ketamine may positively influence mood, moreover having a potential to improve cognition and general quality of life. We report a case of a 49-year-old male hospitalized during a manic and a subsequent moderate depressive episode. After an ineffective use of lithium, olanzapine and antidepressive treatment with mianserin, memantine was added up to 20 mg per day for 10 weeks. The mental state was assessed using the Hamilton Depression Rating Scale, the Young Mania Rating Scale, the Hamilton Anxiety Scale, the Clinical Global Inventory, the World Health Organization Quality of Life Scale and psychological tests. After 10 weeks the patient achieved a partial symptomatic improvement in mood, anxiety and quality of sleep, but his activity remained insufficient. We also observed an improvement in the parameters of cognitive functioning and quality of life. There was neither significant mood variations during the memantine use nor mood changes after its termination. No significant side effects were noted during the memantine treatment. We conclude that using memantine in bipolar depression may improve mood, cognitive functioning and quality of life.

Abstract
UNLABELLED Memantine is a noncompetitive NMDA receptor antagonist. As an augmenting agent, it has an antidepressant-like and mood-stabilizing effect. Memantine also reduces binge eating episodes and weight. We investigated whether memantine added on to valproate (VPA) is more effective than VPA alone for treating BP-II depression and improving the patient's metabolic profile. This was a randomized, double-blind, controlled study. BP-II patients undergoing regular VPA treatments were randomly assigned to one of two groups: VPA plus either add-on [1] memantine (5 mg/day) (n = 62) or [2] placebo (n = 73) for 12 weeks. The Young Mania Rating Scale (YMRS) and Hamilton Depression Rating Scale (HDRS) were used to evaluate clinical response. Height, weight, fasting serum glucose, fasting total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides were followed regularly. Multiple linear regressions with generalized estimating equation methods were used to analyze the effects of memantine on clinical performance. There were no significant differences in pre- and post-treatment YMRS and HDRS scores between the VPA + memantine and VPA + placebo groups. Although there were no significant differences in the pre- and post-treatment values of most metabolic indices between the two groups, there was a significant increase of HDL-C (p = 0.009) in the VPA + memantine group compared with the VPA + placebo group. This increase remained significant even after controlling for body mass index (BMI) (p = 0.020). We conclude that add-on memantine plus VPA treatment of BP-II depression increases the blood level of HDL-C even in the absence of change in affective symptoms.

Abstract
Administration of NMDA receptor antagonists, such as ketamine and MK-801, may induce psychotic-like behaviors in preclinical models of schizophrenia. Ketamine has also been observed to exacerbate psychotic symptoms in schizophrenia patients. However, memantine, a non-competitive NMDA receptor antagonist approved for Alzheimer's disease and proposed for antipsychotic augmentation, may challenge this view. To date, the molecular mechanisms by which these NMDA receptor antagonists cause different neurochemical, behavioral, and clinical effects are still a matter of debate. Here, we investigated by molecular imaging whether these agents could differently modulate gene expression and topographical distribution of glutamatergic postsynaptic density (PSD) proteins. We focused on Homer1a/Homer1b/PSD-95 signaling network, which may be implicated in glutamate-dependent synaptic plasticity, as well as in psychosis pathophysiology and treatment. Ketamine (25 and 50mg/kg) and MK-801 (0.8mg/kg) significantly induced the transcripts of immediate-early genes (Arc, c-fos, and Homer1a) in cortical regions compared to vehicle, whereas they reduced Homer1b and PSD-95 expression in cortical and striatal regions. Differently, memantine (5mg/kg) did not increase Homer1a signal compared to vehicle, whereas it induced c-fos in the somatosensory and in the medial agranular cortices. Moreover, memantine did not affect Homer1b and PSD-95 expression. When compared to ketamine and MK-801, memantine significantly increased the expression of c-fos, Homer1b and PSD-95. Overall, ketamine and MK-801 prominently increased Homer1a/Homer1b expression ratio, whereas memantine elicited the opposite effect. These data may support the view that ketamine, MK-801 and memantine exert divergent effects on PSD transcripts, which may contribute to their partially different behavioral and clinical effects.

Abstract
INTRODUCTION Bipolar disorder (BD) is a severe and chronic medical condition typified by episodic recurrent mania (or hypomania) in addition to major depression. BD is associated with a number of negative outcomes including premature death, reduced quality of life and can also lead to other complications including impaired cognitive function. Unfortunately, the currently available pharmacological treatments for BD are insufficient for many with the condition. AREAS COVERED This review focuses on known therapeutic targets of mood stabilizing drugs including: the glycogen synthase kinase-3 (GSK-3), the phosphoinositide pathway and protein kinase C (PKC), the brain-derived neurotrophic factor (BDNF), and histone deacetylases (HDACs). This article also presents new promising therapeutic targets including: the glutamatergic pathway, mitochondrial modulators, neuropeptide-converting endopeptidases, the insulin transduction pathway, the purinergic system and the melatoninergic system. EXPERT OPINION Challenges in improving methods and tools to generate, integrate and analyze high-dimensional data are required to allow opening novel routes to BD drug discovery. Through the application of systems biology approaches and the use of bioinformatical tools to integrate all omics data, it will be possible in the near future to gain deeper insights into pathophysiology of BD. This will in turn lead to the identification and exploitation of new potential therapeutic approaches.

Abstract
OBJECTIVES Many patients diagnosed with bipolar disorder (BD) respond incompletely or unsatisfactorily to available treatments. Given the potentially devastating nature of this prevalent disorder, there is a pressing need to improve clinical care of such patients. METHODS We performed a literature review of the research findings related to treatment-resistant BD reported through February 2012. RESULTS Therapeutic trials for treatment-resistant bipolar mania are uncommon, and provide few promising leads other than the use of clozapine. Far more pressing challenges are the depressive-dysthymic-dysphoric-mixed phases of BD and long-term prophylaxis. Therapeutic trials for treatment-resistant bipolar depression have assessed anticonvulsants, modern antipsychotics, glutamate [N-methyl-D-aspartate (NMDA)] antagonists, dopamine agonists, calcium-channel blockers, and thyroid hormones, as well as behavioral therapy, sleep deprivation, light therapy, electroconvulsive therapy (ECT), transcranial magnetic stimulation, and deep brain stimulation-all of which are promising but limited in effectiveness. Several innovative pharmacological treatments (an anticholinesterase, a glutamine antagonist, a calcium-channel blocker, triiodothyronine, olanzapine and topiramate), ECT, and cognitive-behavior therapy have some support for long-term treatment of resistant BD patients, but most of trials of these treatments have been methodologically limited. CONCLUSIONS Most studies identified were small, involved supplementation of typically complex ongoing treatments, varied in controls, randomization, and blinding, usually involved brief follow-up, and lacked replication. Clearer criteria for defining and predicting treatment resistance in BD are needed, as well as improved trial design with better controls, assessment of specific clinical subgroups, and longer follow-up.

Abstract
An up-regulated brain arachidonic acid (AA) cascade and a hyperglutamatergic state characterize bipolar disorder (BD). Lamotrigine (LTG), a mood stabilizer approved for treating BD, is reported to interfere with glutamatergic neurotransmission involving N-methyl-d-aspartate receptors (NMDARs). NMDARs allow extracellular calcium into the cell, thereby stimulating calcium-dependent cytosolic phospholipase A2 (cPLA2) to release AA from membrane phospholipid. We hypothesized that LTG, like other approved mood stabilizers, would reduce NMDAR-mediated AA signalling in rat brain. An acute subconvulsant dose of NMDA (25 mg/kg) or saline was administered intraperitoneally to unanaesthetized rats that had been treated p.o. daily for 42 d with vehicle or a therapeutically relevant dose of LTG (10 mg/kg.d). Regional brain AA incorporation coefficients k* and rates J in, and AA signals, were measured using quantitative autoradiography after intravenous [1-14C]AA infusion, as were other AA cascade markers. In chronic vehicle-treated rats, acute NMDA compared to saline increased k* and J in in widespread regions of the brain, as well as prostaglandin (PG)E2 and thromboxane B2 concentrations. Chronic LTG treatment compared to vehicle reduced brain cyclooxygenase (COX) activity, PGE2 concentration, and DNA-binding activity of the COX-2 transcription factor, NF-κB. Pretreatment with chronic LTG blocked the acute NMDA effects on AA cascade markers. In summary, chronic LTG like other mood stabilizers blocks NMDA-mediated signalling involving the AA metabolic cascade. Since markers of the AA cascade and of NMDAR signalling are up-regulated in the post-mortem BD brain, mood stabilizers generally may be effective in BD by dampening NMDAR signalling and the AA cascade.

Abstract
Memantine, a non-competitive NMDA receptor antagonist approved for Alzheimer's disease with a good safety profile, is increasingly being studied in a variety of non-dementia psychiatric disorders. We aimed to critically review relevant literature on the use of the drug in such disorders. We performed a PubMed search of the effects of memantine in animal models of psychiatric disorders and its effects in human studies of specific psychiatric disorders. The bulk of the data relates to the effects of memantine in major depressive disorder and schizophrenia, although more recent studies have provided data on the use of the drug in bipolar disorder as an add-on. Despite interesting preclinical data, results in major depression are not encouraging. Animal studies investigating the possible usefulness of memantine in schizophrenia are controversial; however, interesting findings were obtained in open studies of schizophrenia, but negative placebo-controlled, double-blind studies cast doubt on their validity. The effects of memantine in anxiety disorders have been poorly investigated, but data indicate that the use of the drug in obsessive-compulsive disorder and post-traumatic stress disorder holds promise, while findings relating to generalized anxiety disorder are rather disappointing. Results in eating disorders, catatonia, impulse control disorders (pathological gambling), substance and alcohol abuse/dependence, and attention-deficit hyperactivity disorder are inconclusive. In most psychiatric non-Alzheimer's disease conditions, the clinical data fail to support the usefulness of memantine as monotherapy or add-on treatment However, recent preclinical and clinical findings suggest that add-on memantine may show antimanic and mood-stabilizing effects in treatment-resistant bipolar disorder.

Abstract
Mania has long been recognized as aberrant behaviour indicative of mental illness. Manic states include a variety of complex and multifaceted symptoms that challenge clear clinical distinctions. Symptoms include over-activity, hypersexuality, irritability and reduced need for sleep, with cognitive deficits recently linked to functional outcome. Current treatments have arisen through serendipity or from other disorders. Hence, treatments are not efficacious for all patients, and there is an urgent need to develop targeted therapeutics. Part of the drug discovery process is the assessment of therapeutics in animal models. Here we review pharmacological, environmental and genetic manipulations developed to test the efficacy of therapeutics in animal models of mania. The merits of these models are discussed in terms of the manipulation used and the facet of mania measured. Moreover, the predictive validity of these models is discussed in the context of differentiating drugs that succeed or fail to meet criteria as approved mania treatments. The multifaceted symptomatology of mania has not been reflected in the majority of animal models, where locomotor activity remains the primary measure. This approach has resulted in numerous false positives for putative treatments. Recent work highlights the need to utilize multivariate strategies to enable comprehensive assessment of affective and cognitive dysfunction. Advances in therapeutic treatment may depend on novel models developed with an integrated approach that includes: (i) a comprehensive battery of tests for different aspects of mania, (ii) utilization of genetic information to establish aetiological validity and (iii) objective quantification of patient behaviour with translational cross-species paradigms.

[PMID: 22030128 DOI: 10.1016/j.jad.2011.09.040] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2011] [Revised: 08/28/2011] [Accepted: 09/28/2011] [Indexed: 12/26/2022]
Abstract
BACKGROUND We have recently provided preliminary clinical observations indicating that memantine, as augmenting agent, was associated with a meaningful antimanic and mood-stabilizing effect in treatment-resistant bipolar disorders. To further investigate the therapeutic and prophylactic action of the drug we administered memantine, as augmenting agent, to 40 treatment-resistant bipolar disorder patients, monitored and evaluated for 12 months. METHODS The sample population encompassed 40 treatment-resistant bipolar disorder patients monitored for 12 months. Memantine, at the dose of 10-30 mg/day, was added to the ongoing treatment, which was left unmodified. The severity of the patients' condition before memantine and the changes after memantine addition were evaluated on the Clinical Global Impression Bipolar (CGI-BP) Overall Bipolar Illness Scale. The severity of patients' condition was scored before memantine and the change was evaluated after memantine addition at 6 and 12 months. LIMITATIONS The present study has the limitations of an open clinical study and the observed effects require testing in a blinded, randomized, controlled trial which is planned. RESULTS The average CGI-BP score of the patients was 6.7 (SD=0.58, range: 5-7) before the addition of memantine. After 6 months of memantine treatment, 72.5% of patients were very much or much improved. Among the rapid cyclers 68.4% of patients reached stability, defined by the absence of recurrences. Patients very much or much improved were 72.5% at 12 months; while 12.5% discontinued memantine or were lost to follow-up. CONCLUSIONS The results confirm our previous observations and strongly suggest that memantine, as augmenting agent, was associated with a clinically substantial antimanic and sustained mood-stabilizing effect, with excellent safety and tolerability profile.

Abstract
Bipolar disorder (BD) is one of the most potentially severe mental disorders. Literature data indicate that despite the current available treatments, a large proportion of patients do not achieve complete remission, with consequent residual symptoms and chronic impairment. We carried out a comprehensive review of new pharmacologic treatments for BD. Even though the core treatment of BD likely will not likely undergo substantial changes over the next few years, many promising results with respect to new augmentation strategies were identified. New treatments for bipolar depression and for BD-related cognitive impairment seem to represent particularly fertile areas of research.
