Pharmacological Mechanism of Herbal Interventions for Bipolar Disorder

: Bipolar disorder is a neuropsychiatric disease characterized by an abundance of undesired ideas and thoughts associated with recurrent episodes of mania or hypomania and depression. Alterations in the circuits, including the prefrontal cortex, striatum, and limbic system, regulate mood and cause variation in several crucial neurotransmitters, including serotonin, dopamine, GABA, and glutamate. Imbalances in dopamine levels have been implicated in the manic phase, while variance in serotonin is linked to depressive episodes. The precise pathophysiology of bipolar disorder is still unknown. Though different treatments are available, like lithium, risperidone, valproic acid, etc., which are widely used, they come with certain limitations, including narrow therapeutic index, hypothyroidism, weight gain, extrapyramidal symptoms, etc. The interest in herbal- based treatments for bipolar disorder arises from the desire for alternative, potentially more natural, and holistic approaches with fewer side effects. The current review focuses on the potential effects of herbal drugs and their derivatives to alleviate the symptoms of bipolar disorder.

Psychotherapies for the Treatment of Bipolar Disorder

Bipolar disorder is one of the major mental disorders leading to disability. This review aims to highlight the most effective psychotherapies used in the treatment of bipolar disorder. Across diverse schools of psychology, five psychotherapeutic approaches have emerged as both highly utilized and effective. These are interpersonal social rhythm therapy, psychoeducation, cognitive-behavioral therapy, family-focused therapy and mindfulness therapy. Multiple randomized controlled trials focusing on these psychotherapeutic interventions have provided strong evidence of their effectiveness when delivered alongside standard care. The results suggest that these approaches have a constructive role to play as adjunctive models of psychotherapy in the management of bipolar disorder. While the available evidence is robust, further randomized clinical trials are needed. Expanding these studies to sub-areas such as geriatrics and adolescents would provide more detailed information on the feasibility and efficacy of these psychotherapies among different demographic groups.

Measurement of lithium response in patients with bipolar disorder using the Retrospective Assessment of Response to Lithium Scale (Alda scale)

Lithium is the first-line medication for the treatment of bipolar disorder (BD), but its exact biological mechanisms have not been identified. One of the major obstacles in lithium-related research is the difficulty in precisely and reliably measuring the response to lithium. The Alda scale was developed to retrospectively measure lithium response in a standardized way. However, several aspects should be considered in understanding previous studies that used the Alda scale. In this narrative review, we aim to review previous studies and present the limitations of prior findings. Additionally, we suggest future strategies for applying the Alda scale in measuring lithium response. Initial studies using the Alda scale mainly included patients who were on lithium monotherapy for a long-term period. However, lithium monotherapy is relatively rare in clinical practice. More importantly, in clinical practice, if patients do not respond well to lithium, clinicians do not prescribe it for a long-term period. Thus, a modified approach to include diverse patients is necessary to identify true poor responders. Most previous studies also mainly included European populations, and ancestrally diverse populations should be included in the research. Furthermore, applying the same scale to explore the effects of other medications would also enhance our understanding of the neurobiological mechanisms of psychiatric medications in BD. Applying electronic health record data in evaluating lithium response would soon facilitate large-scale studies. Future studies that include diverse clinical populations reflecting the clinical practice are necessary to advance precision psychiatry.

Improving Social and Personal Rhythm Dysregulation in Young and Old Adults with Bipolar Disorder: Post-Hoc Analysis of a Feasibility Randomized Controlled Trial Using Virtual Reality-Based Intervention.

Introduction: Rehabilitative interventions employing technology play a crucial role in bipolar disorder (BD) treatment. The study aims to appraise the virtual reality (VR)-based cognitive remediation (CR) and the interpersonal rhythm approaches to treatment outcomes of BD across different age groups. Methods: Post-hoc analysis of a 12-week randomizedcontrolled cross-over feasibility trial involving people with mood disorders (BD, DSM-IV) aged 18-75 years old: thirty-nine exposed to the experimental VR-based CR vs 25 waiting list controls. People with BD relapse, epilepsy or severe eye diseases (due to the potential VR risks exposure) were excluded. Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) was used to measure the outcome. Results: Cases and controls did not statistically significantly differ in age and sex distributions. Personal rhythm scores improved over the study follow-up in the experimental vs the control group (APC = 8.7%; F = 111.9; p < 0.0001), both in young (18-45 years) (APC = 5.5%; F = 70.46; p < 0.0001) and, to a lesser extent, older (>46 years) adults (APC = 10.5%; F = 12.110; p = 0.002). Conclusions: This study observed improved synchronization of personal and social rhythms in individuals with BD after a virtual reality cognitive remediation intervention, particularly in social activity, daily activities, and chronotype, with greater benefits in the younger population.

Biochanin A Has Protective and Therapeutic Effects against Li2CO3-induced Nephrotoxicity in Rats Model

BACKGROUND: Long-term usage of lithium carbonate (Li2CO3) as treatment of bipolar disorder might cause nephrotoxicity. Li2CO3-induced nephrotoxicity usually treated by renal dialysis, which is quite expensive. Usage of natural products that possess anti-inflammatory and antioxidant properties as biochanin A (BCA) may be useful against Li2CO3 nephrotoxicity. Therefore, this study was conducted to evaluate Li2CO3 nephrotoxic effects and BCA therapeutic and protective effects against it.METHODS: Twenty-eight rats divided into 4 groups: negative control (NC), Li2CO3, Li2CO3 + BCA therapeutic, and BCA + Li2CO3 protective group. Complete blood picture, serum kidney function tests (urea, creatinine, and cystatin C) and kidney tissue homogenate oxidative stress index as malonaldehyde (MDA), superoxide dismutase (SOD), glutathione S-transferase (GST) and catalase (CAT) were measured using enzyme linked immunosorbent assay (ELISA) methods. While, kidney histopathological changes were evaluated under light microscope.RESULTS: Li2CO3 administration elicited significant changes in hematological parameters as hypochromic anemia, decreased platelets and leukocytosis. Serum urea, creatinine and cystatin C were elevated. Renal homogenate analysis revealed significant elevation of MDA and decline in GST, CAT, SOD levels. Kidney histopathology analysis revealed hemorrhage between renal tubules, glomerular capillaries congestion, Bowman’s space dilatation, structural alterations in renal tubules cells include loss of brush border, deeply stained nuclei and elevated in size and number of cytoplasmic vacuoles. Therapeutic and protective groups of BCA showed amelioration of hematological alteration, kidney functions, oxidative stress markers and restoration of kidney tissues.CONCLUSION: BCA has both protective and therapeutic effects against Li2CO3-induced nephrotoxicity possibly through the reduction of oxidative stress.KEYWORDS: biochanin A, hematological changes, kidney, lithium carbonate salt, oxidative stress, protective effects, therapeutic effects

Lithium, the gold standard drug for bipolar disorder: analysis of current clinical studies.

Lithium is the gold standard drug in the treatment of bipolar disorder. Despite increasing scientific interest, relatively few patients with bipolar disorder receive lithium therapy. Lithium is the only drug that is effective in the prophylaxis of manic, depressive, and suicidal symptoms. Lithium therapy is also associated with a variety of adverse drug reactions and the need for therapeutic drug monitoring. Numerous studies have focussed on the efficacy and safety of both lithium-monotherapy and lithium-add-on therapy. The aim of this study is to provide a systematic overview of clinicalstudies on lithium therapy for bipolar disorder from the last 7 years and to present a critical analysis of these studies. The results provide an up-to-date overview of the efficacy, tolerability, and safety of lithium therapy for bipolar disorder and thus improve the pharmacotherapy of bipolar disorder. A total of 59 studies were analysed using various analysis parameters. The studies were also categorised into different subgroups. These are lithium-monotherapy, lithium vs. placebo/drug, and lithium + adjunctive therapy. The majority of the studies (N = 20) had a duration of only 3-8 weeks. Only 13 studies lasted for > 40 weeks. Lithium was superior to aripiprazole, valproic acid, and quetiapine in terms of improving manic symptoms. Lithium therapy resulted in a lower relapse rate compared to valproic acid therapy. Lithium was more neuroprotectively effective than quetiapine. Fourteen of the 22 add-on therapies to lithium showed a predominantly positive effect on the treatment outcome compared to lithium-monotherapy. Only the add-on therapy with sertraline led to a higher rate of study discontinuations than lithium-monotherapy. Lithium is a safe and effective treatment option for children. However, risperidone and quetiapine were superior to lithium in some aspects, which is why these drugs should be considered as an alternative treatment option for children. Collectively, current clinical studies highlight the relevance of lithium in the treatment of bipolar disorder.

Pharmacological treatment for mental health illnesses in adults receiving dialysis: A scoping review.

Pharmacologic management of mental health illnesses in patients receiving dialysis is complex and lacking data. Our objective was to synthesize published data for the treatment of depression, bipolar and related disorders, schizophrenia or psychotic disorders, and anxiety disorders in adults receiving hemodialysis or peritoneal dialysis. We undertook a scoping review, searching the following databases: Medline, Embase, CINAHL, PsycINFO, Cochrane Library, Scopus, and Web of Science. Data on patients who received only short-term dialysis, a kidney transplant, or non-pharmacologic treatments were excluded. Seventy-three articles were included: 41 focused on depression, 16 on bipolar disorder, 13 on schizophrenia and psychotic disorders, 1 on anxiety disorders, and 2 addressing multiple mental health illnesses. The majority of depression studies reported on selective serotonin reuptake inhibitors (SSRIs) as a treatment. Sertraline had the most supporting data with use of doses from 25 to 200 mg daily. Among the remaining SSRIs, escitalopram, citalopram, and fluoxetine were studied in controlled trials, whereas paroxetine and fluvoxamine were described in smaller reports and observational trials. There are limited published data on other classes of antidepressants and on pharmacological management of anxiety. Data on treatment for patients with bipolar disorder or schizophrenia and related disorders are limited to case reports. Over half of the studies included were case reports, thus limiting conclusions. More robust data are required to establish effect sizes of pharmacological treatments prior to providing specific recommendations for their use in treating mental health illnesses in patients receiving dialysis.

A grounded theory on acceptance of diagnosis as a pathway to recovery in bipolar disorder

The recovery process in bipolar disorder is a subjective and multidimensional experience that seeks to develop new meanings and purposes for living a satisfying life despite the limitations imposed by the disorder. Thus, this qualitative study aimed to explore the perceptions of recovery and the meanings attributed by individuals undergoing treatment for bipolar disorder to the elements considered relevant in this process. Semi-structured interviews with open-ended questions were conducted to explore the experiences and perspectives of recovery in individuals undergoing treatment for bipolar disorder. Grounded Theory was used as the method for qualitative analysis. The study included 26 participants aged between 18 and 65 years. Based on the analysis of participant reports, we identified two main themes: living with the illness and what it means to be in recovery. The perception of recovery is an individual process and can differ from the medical model. Participants suggest that accepting the diagnosis of bipolar disorder and finding meaning in life are essential to their recovery. They also describe how mental health professionals can facilitate or hinder this process. Understanding patients’ perceptions can facilitate access to healthcare services and treatment adherence.

N-(4-Bromo-2,5-Dimethoxyphenethyl)-6-(4-Phenylbutoxy)Hexan-1-Amine (XOB): A Novel Phenylalkylamine Antagonist of Serotonin 2A Receptors and Voltage-Gated Sodium Channels.

Bipolar disorder impacts millions of patients in the United States but the mechanistic understanding of its pathophysiology and therapeutics is incomplete. Atypical antipsychotic serotonin2A (5-HT2A) receptor antagonists, such as quetiapine and olanzapine, and mood-stabilizing voltage-gated sodium channel (VGSC) blockers, such as lamotrigine, carbamazepine, and valproate, show therapeutic synergy and are often prescribed in combination for the treatment of bipolar disorder. Combination therapy is a complex task for clinicians and patients, often resulting in unexpected difficulties with dosing, drug tolerances, and decreased patient compliance. Thus, an unmet need for bipolar disorder treatment is to develop a therapeutic agent that targets both 5-HT2A receptors and VGSCs. Toward this goal, we developed a novel small molecule that simultaneously antagonizes 5-HT2A receptors and blocks sodium current. The new compound, N-(4-bromo-2,5-dimethoxyphenethyl)-6-(4-phenylbutoxy)hexan-1-amine (XOB) antagonizes 5-HT-stimulated, Gq-mediated, calcium flux at 5-HT2A receptors at low micromolar concentrations while displaying negligible affinity and activity at 5-HT1A, 5-HT2B, and 5-HT2C receptors. At similar concentrations, XOB administration inhibits sodium current in heterologous cells and results in reduced action potential (AP) firing and VGSC-related AP properties in mouse prefrontal cortex layer V pyramidal neurons. Thus, XOB represents a new, proof-of-principle tool that can be used for future preclinical investigations and therapeutic development. This polypharmacology approach of developing a single molecule to act upon two targets, which are currently independently targeted by combination therapies, may lead to safer alternatives for the treatment of psychiatric disorders that are increasingly being found to benefit from the simultaneous targeting of multiple receptors. SIGNIFICANCE STATEMENT: The authors synthesized a novel small molecule (XOB) that simultaneously antagonizes two key therapeutic targets of bipolar disorder, 5-HT2A receptors and voltage-gated sodium channels, in heterologous cells, and inhibits the intrinsic excitability of mouse prefrontal cortex layer V pyramidal neurons in brain slices. XOB represents a valuable new proof-of-principle tool for future preclinical investigations and provides a novel molecular approach to the pharmacological treatment of complex neuropsychiatric disease, which often requires a combination of therapeutics for sufficient patient benefit.

An Retrospective Study of Commonly Prescribed Antiepileptic Drugs and it’s Interaction with Other Drugs which are Already in use Respect to Other Disease

Antiepileptic drugs (AED) are increasingly used in the treatment of some non-epileptic neurological diseases and psychiatric diseases. Most of the available data on the use of these agents in clinical conditions other than epilepsy are from case series, uncontrolled studies, or small randomized clinical trials, and their apparent efficacy requires confirmation in well-designed large phase III trials. Interactions between antiepileptic drugs or between antiepileptic drugs and other drugs can be pharmacokinetic or pharmacodynamic. Pharmacokinetic interactions include changes in absorption, distribution ,or eliminate , while pharmacodynamic interactions include synergism and antagonism at the site ,of action. Most clinically significant antiepileptic drug interactions are due to induction or inhibition of drug metabolism. Carbamazepine, phenytoin, phenobarbital and primidone are strong inducers of cytochrome P450 and glucuronide enzymes (as well as P-glycoprotein) and may reduce the effectiveness of concomitantly administered drugs such as oral anticoagulants, calcium antagonists, antimicrobial steroids. Mechanism Oxcarbazepine, eslicarbazepine acetate, felbamate, rufinamide, topiramate (at doses ≥ 200 mg/day) and perampanel (at doses ≥ 8 mg/day) have weaker inducing properties and less tendency to produce interactions mediated by enzyme induction. In contrast to enzyme induction, enzyme inhibition results in decreased metabolic clearance of the affected drug, which can increase serum concentrations leading to toxic effects. Examples of important interactions mediated by enzyme inhibition include valproic-induced increases in serum concentrations of phenobarbital and lamotrigine. There are also interactions where other drugs induce or inhibit the metabolism of antiepileptic drugs. Examples include an increase in serum carbamazepine concentration due to erythromycin and a decrease in serum lamotrigine concentration due to estrogen-containing contraceptives. Pharmacodynamic interactions between antiepileptic drugs may also be clinically important. These interactions can have potentially beneficial effects, such as the combined therapeutic synergy of valproic acid and lamotrigine, or adverse effects, such as the mutual potentiation of neurotoxicity in patients treated with a combination of sodium channel blocking antiepileptic drugs. AEDs are also used to treat psychiatric conditions, particularly bipolar disorder. To date, the AEDs most commonly used to treat this disorder have been carbamazepine and valproic acid, which have shown manic efficacy and likely long-term mood-stabilizing effects in many bipolar patients, including those who are lithium-intolerant. . The availability of new generation AEDs has expanded treatment options for bipolar disorder. Lamotrigine, oxcarbazepine, gabapentin, and topiramate appear to show promise in the treatment of bipolar disorder, both as monotherapy and in combination with traditional mood stabilizers. In addition, newer AEDs appear to have a more favorable tolerability and drug interaction profile than older compounds, thus improving compliance

Integrated proteomic and genomic analysis to identify predictive biomarkers for valproate response in bipolar disorder: a 6-month follow-up study

BackgroundSeveral genetic studies have been undertaken to elucidate the intricate interplay between genetics and drug responses in bipolar disorder (BD). However, there has been notably limited research on biomarkers specifically linked to valproate, with only a few studies investigating integrated proteomic and genomic factors in response to valproate treatment. Therefore, this study aimed to identify biological markers for the therapeutic response to valproate treatment in BD. Patients with BD in remission were assessed only at baseline, whereas those experiencing acute mood episodes were evaluated at three points (baseline, 8 ± 2 weeks, and 6 ± 1 months). The response to valproate treatment was measured using the Alda scale, with individuals scoring an Alda A score ≥ 5 categorized into the acute-valproate responder (acute-VPAR) group. We analyzed 158 peptides (92 proteins) from peripheral blood samples using multiple reaction monitoring mass spectrometry, and proteomic result-guided candidate gene association analyses, with 1,627 single nucleotide variants (SNVs), were performed using the Korean chip.ResultsThe markers of 37 peptides (27 protein) showed temporal upregulation, indicating possible association with response to valproate treatment. A total of 58 SNVs in 22 genes and 37 SNVs in 16 genes showed nominally significant associations with the Alda A continuous score and the acute-VPAR group, respectively. No SNVs reached the genome-wide significance threshold; however, three SNVs (rs115788299, rs11563197, and rs117669164) in the secreted phosphoprotein 2 gene reached a gene-based false discovery rate-corrected significance threshold with response to valproate treatment. Significant markers were associated with the pathophysiological processes of bipolar disorders, including the immune response, acute phase reaction, and coagulation cascade. These results suggest that valproate effectively suppresses mechanisms associated with disease progression.ConclusionsThe markers identified in this study could be valuable indicators of the underlying mechanisms associated with response to valproate treatment.

LiFT (a Lithium Fiber-Based Test): An At-Home Companion Diagnostics for a Safer Lithium Therapy in Bipolar Disorder.

This work presents LiFT (a lithium fiber-based test), a low-cost electrochemical sensor that can measure lithium in human saliva and urine with FDA-required accuracy. Lithium is used for the treatment of bipolar disorder, and has a narrow therapeutic window. Close monitoring of lithium concentration in biofluids and adjustment of drug dosage can minimize the devastating side effects. LiFT is an inexpensive, yet accurate and simple-to-operate lithium sensor for frequent at-home testing for early identification of lithium toxicity. The low cost and high accuracy of LiFT are enabled through an innovative design and the use of ubiquitous materials such as yarn and carbon black for fabrication. LiFT measures Li+ through potentiometric recognition using a lithium selective sensing membrane that is deposited on the ink-coated yarn. A detection limit of 0.97 µM is obtained with a sensitivity of 59.07±1.25 mV/decade for the Li+ sensor in deionized water. Moreover, the sodium correction extended LiFT's linear range in urine and saliva to 0.5 mM. The LiFT platform sends the test results to the patient's smartphone, which subsequently can be shared with the patient's healthcare provider to expedite diagnosis and prevention of acute lithiumtoxicity.

Cariprazine: An Antipsychotic Medication with High Therapeutic Potential

Introduction and purposeCariprazine is an atypical antipsychotic drug approved for the treatment of schizophrenia, as well as manic and mixed episodes associated with bipolar disorder. It functions as a dopamine multifunctional agent, a partial agonist at dopamine and serotonin receptors. Unlike the majority of antipsychotics, which primarily target positive symptoms through dopaminergic antagonism, often neglecting negative, cognitive, and affective symptoms, the unique cariprazine's pharmacological profile, particularly potent blockade of D3 dopamine receptors, suggests the potential for numerous clinical applications. The aim of this study is to present current knowledge of cariprazine, focusing particularly on its mechanism of action, potential applications, adverse effects, and pharmacokinetic properties that could impact its clinical use.Methods and materialsA review of the literature available in the PubMed database was performed using the key words: cariprazine; atypical antipsychotic drug; antipsychotic medication; schizophrenia treatment; bipolar disorder treatment; mania treatment; depression treatment, dopamine agonist.ConclusionsCariprazine demonstrates a unique pharmacological profile, offering potential benefits in managing a wide range of psychiatric disorders, including schizophrenia, bipolar disorder (mania, depression, mixed episodes), unipolar depression, and co-occurring substance use disorders. Clinical studies have shown efficacy in reducing symptoms and improving negative and cognitive function, with a favorable metabolic profile, minimal impact on cardiovascular system, and generally mild adverse effect profile. However, further research is necessary to explore its full therapeutic potential and optimize its clinical use in diverse patient populations.

Combining predominant polarity and affective spectrum concepts in bipolar disorder: towards a novel theoretical and clinical perspective

This is an overview of recent advances on predominant polarity conceptualization in bipolar disorder (BD). Current evidence on its operationalized definitions, possible contextualization within the affective spectrum, along with its epidemiological impact, and treatment implications, are summarized. Predominant polarity identifies three subgroups of patients with BD according to their mood recurrencies: (i) those with depressive or (ii) manic predominance as well as (iii) patients without any preponderance (‘nuclear’ type). A predominant polarity can be identified in approximately half of patients, with similar rates for depressive and manic predominance. Different factors may influence the predominant polarity, including affective temperaments. More generally, affective disorders should be considered as existing on a spectrum ranging from depressive to manic features, also accounting for disorders with ‘ultrapredominant’ polarity, i.e., unipolar depression and mania. While mixed findings emerge on its utility in clinical practice, it is likely that the construct of predominant polarity, in place of conventional differentiation between BD-I and BD-II, may be useful to clarify the natural history of the disorder and select the most appropriate interventions. The conceptualization of predominant polarity seems to reconcile previous theoretical views of both BD and affective spectrum into a novel perspective. It may provide useful information to clinicians for the early identification of possible trajectories of BD and thus guide them when selecting interventions for maintenance treatment. However, further research is needed to clarify the specific role of predominant polarity as a key determinant of BD course, outcome, and treatment response.
