The Canadian Network for Mood and Anxiety Treatments (CANMAT) previously published treatment guidelines for bipolar disorder in 2005, along with international commentaries and subsequent updates in 2007, 2009, and 2013. The last two updates were published in collaboration with the International Society for Bipolar Disorders (ISBD). These 2018 CANMAT and ISBD Bipolar Treatment Guidelines represent the significant advances in the field since the last full edition was published in 2005, including updates to diagnosis and management as well as new research into pharmacological and psychological treatments. These advances have been translated into clear and easy to use recommendations for first, second, and third‐ line treatments, with consideration given to levels of evidence for efficacy, clinical support based on experience, and consensus ratings of safety, tolerability, and treatment‐emergent switch risk. New to these guidelines, hierarchical rankings were created for first and second‐ line treatments recommended for acute mania, acute depression, and maintenance treatment in bipolar I disorder. Created by considering the impact of each treatment across all phases of illness, this hierarchy will further assist clinicians in making evidence‐based treatment decisions. Lithium, quetiapine, divalproex, asenapine, aripiprazole, paliperidone, risperidone, and cariprazine alone or in combination are recommended as first‐line treatments for acute mania. First‐line options for bipolar I depression include quetiapine, lurasidone plus lithium or divalproex, lithium, lamotrigine, lurasidone, or adjunctive lamotrigine. While medications that have been shown to be effective for the acute phase should generally be continued for the maintenance phase in bipolar I disorder, there are some exceptions (such as with antidepressants); and available data suggest that lithium, quetiapine, divalproex, lamotrigine, asenapine, and aripiprazole monotherapy or combination treatments should be considered first‐line for those initiating or switching treatment during the maintenance phase. In addition to addressing issues in bipolar I disorder, these guidelines also provide an overview of, and recommendations for, clinical management of bipolar II disorder, as well as advice on specific populations, such as women at various stages of the reproductive cycle, children and adolescents, and older adults. There are also discussions on the impact of specific psychiatric and medical comorbidities such as substance use, anxiety, and metabolic disorders. Finally, an overview of issues related to safety and monitoring is provided. The CANMAT and ISBD groups hope that these guidelines become a valuable tool for practitioners across the globe.

Background: The Canadian Network for Mood and Anxiety Treatments (CANMAT) conducted a revision of the 2009 guidelines by updating the evidence and recommendations. The scope of the 2016 guidelines remains the management of major depressive disorder (MDD) in adults, with a target audience of psychiatrists and other mental health professionals. Methods: Using the question-answer format, we conducted a systematic literature search focusing on systematic reviews and meta-analyses. Evidence was graded using CANMAT-defined criteria for level of evidence. Recommendations for lines of treatment were based on the quality of evidence and clinical expert consensus. ''Pharmacological Treatments'' is the third of six sections of the 2016 guidelines. With little new information on older medications, treatment recommendations focus on second-generation antidepressants.Results: Evidence-informed responses are given for 21 questions under 4 broad categories: 1) principles of pharmacological management, including individualized assessment of patient and medication factors for antidepressant selection, regular and

Canadian Network for Mood and Anxiety Treatments (CANMAT) and International Society for Bipolar Disorders (ISBD) collaborative update of CANMAT guidelines for the management of patients with bipolar disorder: update 2013. 
Bipolar Disord 2012: 00: 000–000. © 2012 John Wiley & Sons A/S.Published by Blackwell Publishing Ltd.The Canadian Network for Mood and Anxiety Treatments published guidelines for the management of bipolar disorder in 2005, with updates in 2007 and 2009. This third update, in conjunction with the International Society for Bipolar Disorders, reviews new evidence and is designed to be used in conjunction with the previous publications.The recommendations for the management of acute mania remain largely unchanged. Lithium, valproate, and several atypical antipsychotic agents continue to be first‐line treatments for acute mania. Monotherapy with asenapine, paliperidone extended release (ER), and divalproex ER, as well as adjunctive asenapine, have been added as first‐line options.For the management of bipolar depression, lithium, lamotrigine, and quetiapine monotherapy, as well as olanzapine plus selective serotonin reuptake inhibitor (SSRI), and lithium or divalproex plus SSRI/bupropion remain first‐line options. Lurasidone monotherapy and the combination of lurasidone or lamotrigine plus lithium or divalproex have been added as a second‐line options. Ziprasidone alone or as adjunctive therapy, and adjunctive levetiracetam have been added as not‐recommended options for the treatment of bipolar depression. Lithium, lamotrigine, valproate, olanzapine, quetiapine, aripiprazole, risperidone long‐acting injection, and adjunctive ziprasidone continue to be first‐line options for maintenance treatment of bipolar disorder. Asenapine alone or as adjunctive therapy have been added as third‐line options.

The Canadian Network for Mood and Anxiety Treatments (CANMAT) published guidelines for the management of bipolar disorder in 2005, with a 2007 update. This second update, in conjunction with the International Society for Bipolar Disorders (ISBD), reviews new evidence and is designed to be used in conjunction with the previous publications. The recommendations for the management of acute mania remain mostly unchanged. Lithium, valproate, and several atypical antipsychotics continue to be first-line treatments for acute mania. Tamoxifen is now suggested as a third-line augmentation option. The combination of olanzapine and carbamazepine is not recommended. For the management of bipolar depression, lithium, lamotrigine, and quetiapine monotherapy, olanzapine plus selective serotonin reuptake inhibitor (SSRI), and lithium or divalproex plus SSRI/bupropion remain first-line options. New data support the use of adjunctive modafinil as a second-line option, but also indicate that aripiprazole should not be used as monotherapy for bipolar depression. Lithium, lamotrigine, valproate, and olanzapine continue to be first-line options for maintenance treatment of bipolar disorder. New data support the use of quetiapine monotherapy and adjunctive therapy for the prevention of manic and depressive events, aripiprazole monotherapy for the prevention of manic events, and risperidone long-acting injection monotherapy and adjunctive therapy, and adjunctive ziprasidone for the prevention of mood events. Bipolar II disorder is frequently overlooked in treatment guidelines, but has an important clinical impact on patients' lives. This update provides an expanded look at bipolar II disorder.

There is increasing evidence for efficacy, tolerability, and safety of neurostimulation treatments. rTMS is now a first-line recommendation for patients with MDD who have failed at least 1 antidepressant. ECT remains a second-line treatment for patients with treatment-resistant depression, although in some situations, it may be considered first line. Third-line recommendations include tDCS and VNS. MST and DBS are still considered investigational treatments.

Sr. Editor, Nos últimos anos, a psiquiatria brasileira avançou muito no sentido de declarar todo e qualquer potencial conflito de interesse. No último congresso da Associação Brasileira de Psiquiatria (ABP), em Belo Horizonte (MG), todos os partici-pantes foram solicitados a declarar qualquer envolvimento comercial que pudesse, mesmo que remotamente, influen-ciar as suas apresentações. A própria Revista Brasileira de Psiquiatria (RBP) tem orientações muito claras para os auto-res quando da submissão dos artigos. Por isso, foi com grande surpresa que li, na última edição da RBP, o artigo do grupo do GREA-USP, 1 no qual não consta o reconhecimento de conflitos de interesse. É fato público que pelo menos dois dos autores desse artigo trabalham ou trabalharam na época da submissão do artigo numa ONG com financiamento da indústria do álcool (CISA). Na área da dependência química, várias das principais re-vistas internacionais têm códigos muito bem definidos sobre fontes de potencial conflitos de interesse, especialmente quan-do se trata de profissionais que aceitam financiamento da in-dústria do cigarro e do álcool. A declaração de haver, por parte dos profissionais, o envolvimento com a indústria do álcool ou do cigarro, lógico que não coloca necessariamente sob suspeita todo o eventual trabalho sério do ponto de vista científico. No entanto, acho que é um direito dos leitores da RBP saberem as eventuais fontes de conflitos de interesse para desenvolverem a sua própria opinião sobre a influência dessas indústrias na qualidade dos artigos publicados. Espero que os editores da RBP possam corrigir essa falta de informação.

Background: The Canadian Network for Mood and Anxiety Treatments (CANMAT) conducted a revision of the 2009 guidelines by updating the evidence and recommendations. The scope of the 2016 guidelines remains the management of major depressive disorder (MDD) in adults, with a target audience of psychiatrists and other mental health professionals. Methods: Using the question-answer format, we conducted a systematic literature search focusing on systematic reviews and meta-analyses. Evidence was graded using CANMAT-defined criteria for level of evidence. Recommendations for lines of treatment were based on the quality of evidence and clinical expert consensus. This section is the first of six guidelines articles.Results: In Canada, the annual and lifetime prevalence of MDD was 4.7% and 11.3%, respectively. MDD represents the second leading cause of global disability, with high occupational and economic impact mainly attributable to indirect costs. DSM-5 criteria for depressive disorders remain relatively unchanged, but other clinical dimensions (sleep, cognition, physical symptoms) may have implications for depression management. e-Mental health is increasingly used to support clinical and selfmanagement of MDD. In the 2-phase (acute and maintenance) treatment model, specific goals address symptom remission, functional recovery, improved quality of life, and prevention of recurrence. Conclusions:The burden attributed to MDD remains high, whether from individual distress, functional and relationship impairment, reduced quality of life, or societal economic cost. Applying core principles of care, including comprehensive assessment, therapeutic alliance, support of self-management, evidence-informed treatment, and measurement-based care, will optimize clinical, quality of life, and functional outcomes in MDD.
