Risk factors associated with lifetime suicide attempts in bipolar I patients: findings from a French National Cohort. Compr Psychiatry 2009; 50:115-20.

Abstract
Risk factors that may be associated with suicide attempts in bipolar disorder are still a matter of debate. We compared demographic, illness course, clinical, and temperamental features of suicide attempters vs those of nonattempters in a large sample of bipolar I patients admitted for an index manic episode. One thousand ninety patients (attempters = 382, nonattempters = 708) were included in the study. Multivariate analysis evidenced 8 risk factors associated with lifetime suicide attempts as follows: multiple hospitalizations, depressive or mixed polarity of first episode, presence of stressful life events before illness onset, younger age at onset, no free intervals between episodes, female sex, higher number of previous episodes, and cyclothymic temperament. These characteristics may help identify subjects at risk for suicide attempt throughout the course of bipolar disorder. We finally propose to integrate such characteristics into a stress-diathesis model of suicidal behavior, adapted to bipolar patients.

Abstract
BACKGROUND 25-50% of bipolar patients attempt suicide at least once in their lifetime and completed suicide in this population is about 1% annually, about 60 times the rate of the general population. Psychotherapy may be an effective adjunctive option in preventing suicide in bipolar patients. It has been suggested that interpersonal, cognitive and behavioural techniques may be effective in controlling mood shifts, increasing compliance with pharmacotherapy, and maintaining morale in the face of therapeutic adversity and incomplete response. The aim of our study was to systematically review the literature concerning the efficacy of psychosocial interventions in reducing the risk for attempting or committing suicide. METHODS We searched MEDLINE with the combination of the key words 'psychotherapy' or 'psychoeducation' or 'cognitive therapy' or 'behavio(u)ral therapy', 'cognitive-behavio(u)ral' or 'family therapy' or 'social rhythm' or 'rhythm' with 'suicide' and 'bipolar', limited to English language papers published between 1990 and January 2008. Papers were selected based on the criterium that they provided definite data on the role of psychotherapy in suicide prevention, and specifically in bipolar disorder. RESULTS Our search returned 481 references, of which 17 were selected based on the above criteria. The selected papers were classified according to the area of suicide prevention they were dealing with as 1. Psychosocial and demographic factors, 2. Psychological profile and 3. Efficacy of psychotherapies. DISCUSSION Our paper summarizes specific features and correlates of suicide in bipolar patients and possible targets of psychosocial intervention in the prevention of suicide in bipolar patients. Although studies researching the effect of psychosocial interventions on suicidal behaviour are virtually non-existent, hard data concerning the effectiveness of psychosocial interventions in bipolar disorder are emerging, but still suffer from methodological drawbacks.

Abstract
OBJECTIVE To investigate the impact of coexistent psychiatric morbidity on risk of suicide after a suicide attempt. DESIGN Cohort study with follow-up for 21-31 years. SETTING Swedish national register based study. PARTICIPANTS 39 685 people (53% women) admitted to hospital for attempted suicide during 1973-82. MAIN OUTCOME MEASURE Completed suicide during 1973-2003. RESULTS A high proportion of suicides in all diagnostic categories took place within the first year of follow-up (14-64% in men, 14-54% in women); the highest short term risk was associated with bipolar and unipolar disorder (64% in men, 42% in women) and schizophrenia (56% in men, 54% in women). The strongest psychiatric predictors of completed suicide throughout the entire follow-up were schizophrenia (adjusted hazard ratio 4.1, 95% confidence interval 3.5 to 4.8 in men, 3.5, 2.8 to 4.4 in women) and bipolar and unipolar disorder (3.5, 3.0 to 4.2 in men, 2.5, 2.1 to 3.0 in women). Increased risks were also found for other depressive disorder, anxiety disorder, alcohol misuse (women), drug misuse, and personality disorder. The highest population attributable fractions for suicide among people who had previously attempted suicide were found for other depression in women (population attributable fraction 9.3), followed by schizophrenia in men (4.6), and bipolar and unipolar disorder in women and men (4.1 and 4.0, respectively). CONCLUSION Type of psychiatric disorder coexistent with a suicide attempt substantially influences overall risk and temporality for completed suicide. To reduce this risk, high risk patients need aftercare, especially during the first two years after attempted suicide among patients with schizophrenia or bipolar and unipolar disorder.

Abstract
OBJECTIVE To investigate the possible impact of the increased use of antidepressants on suicide rates in the Italian region of Friuli Venezia Giulia (FVG). METHOD Individual-based data on antidepressants in FVG from 1997 to 2006 were obtained from the regional prescription database, and linked to data on suicide for the same period obtained from the regional health information system. Age and sex were considered. RESULTS The number of users of antidepressants increased almost fivefold during the study period. Selective serotonin reuptake inhibitors accounted for 71% of the individual users in 2006. The number of defined daily doses (DDD) per patient increased almost sevenfold. In parallel, the suicide rate decreased by one-third in men as well as in women, and in subjects under and over the age of 60 years. CONCLUSION Suicide rates in FVG have declined in agreement with the hypothesis that the use of antidepressants may prevent suicide.

Abstract
Cognitions in the form of mental images have a more powerful impact on emotion than their verbal counterparts. This review synthesizes the cognitive science of imagery and emotion with transdiagnostic clinical research, yielding novel predictions for the basis of emotional volatility in bipolar disorder. Anxiety is extremely common in patients with bipolar disorder and is associated with increased dysfunction and suicidality, yet it is poorly understood and rarely treated. Mental imagery is a neglected aspect of bipolar anxiety although in anxiety disorders such as posttraumatic stress disorder and social phobia focusing on imagery has been crucial for the development of cognitive behavior therapy (CBT). In this review we present a cognitive model of imagery and emotion applied to bipolar disorder. Within this model mental imagery amplifies emotion, drawing on Clark's cyclical panic model [(1986). A cognitive approach to panic. Behaviour Research and Therapy, 24, 461-470]. We (1) emphasise imagery's amplification of anxiety (cycle one); (2) suggest that imagery amplifies the defining (hypo-) mania of bipolar disorder (cycle two), whereby the overly positive misinterpretation of triggers leads to mood elevation (escalated by imagery), increasing associated beliefs, goals, and action likelihood (all strengthened by imagery). Imagery suggests a unifying explanation for key unexplained features of bipolar disorder: ubiquitous anxiety, mood instability and creativity. Introducing imagery has novel implications for bipolar treatment innovation--an area where CBT improvements are much-needed.

Abstract
Since its “rebirth” in 1966, bipolar disorder (BPD) has rapidly come to occupy a central position in the research and treatment of mood disorders. Compared with major depressive disorder (MDD), BPD is a more serious condition, characterized by much more frequent recurrence, more complex comorbidity, and higher mortality. One major problem is the lack of valid definitions in adult and in child psychiatry; the current definitions are unsatisfactory, and heavily favor an overdiagnosis of MDD. Biological research is partially based on those definitions, which have a short half-life. An additional, dimensional, approach, quantifying hypomania, depression, and anxiety by self-assessment and symptom checklists is recommended, A further, related problem is the early recognition of the onset of BPD, especially in adolescence, and the identification of correlates in childhood. Early and timely diagnosis of BPD is necessary to enable prompt intervention and secondary prevention of the disorder. The paper describes the current status and future directions of developing clinical concepts of bipolarity

Abstract
Antidepressants constitute a central cornerstone in the treatment of depressive syndromes. In bipolar patients, however, there is an ongoing controversy about their usefulness for at least 3 decades. Early reports, mainly concerning tricyclic antidepressants, have repeatedly pointed toward unfavorable side effects on the course of the disorder, namely switching into (hypo)mania, induction of rapid cycling, and increased risk of suicide. Most evidence for both unfavorable and favorable effects has been deducted, thus far, from small studies with methodological flaws. More substantiated evidence only recently became available. From this it appears that, at least, the switch risk, and perhaps also the risk for rapid cycling and new-onset suicidality have been overinterpreted. At the same time, these new data raise doubt about the efficacy of antidepressants as a primary-treatment choice in bipolar depression.

Abstract
The National Strategic Framework for Renal Services introduced the routine reporting of estimated glomerular filtration rates (eGFR) on serum urea and electrolyte tests. Estimated glomerular filtration rates might reduce renal failure induced by lithium and cardiovascular mortality but there are many false positives.

Abstract
In the past few years several papers have reported critically on the risk of suicidal thoughts and behaviour associated with antidepressants, primarily SSRIs. The risk-benefit ratio of antidepressant (AD) treatment has been questioned especially in children and adolescents. The critical publications led to warnings being issued by regulatory authorities such as the FDA, MHRA and EMEA and stimulated new research activity in this field. However, potential harmful effects of antidepressants on suicidality are difficult to investigate in empirical studies because these have several methodological limitations. Randomised controlled trials (RCTs) are the most reliable way to test the hypothesis that AD have such side effects. In addition to meta-analyses of RCTs, complementary research methods should be applied to obtain the most comprehensive information. We undertook a comprehensive review of publications related to the topics ADs, suicide, suicidality, suicidal behaviour and aggression. Based on this comprehensive review we conclude that ADs, including SSRIs, carry a small risk of inducing suicidal thoughts and suicide attempts, in age groups below 25 years, the risk reducing further at the age of about 30-40 years. This risk has to be balanced against the well-known beneficial effects of ADs on depressive and other symptoms (anxiety, panic, obsessive-compulsive symptoms), including suicidality and suicidal behaviour. According to the principles of good clinical practice, decision making should consider carefully the beneficial effects of AD treatment as well as potentially harmful effects and attempt to keep the potential risks of AD treatment to a minimum. It is the major problem facing efforts to identify the possible 'suicidal effects' of antidepressants.

Abstract
OBJECTIVE Relationships between antidepressant treatment and suicidality remain uncertain in major depressive disorder (MDD), and rarely evaluated in bipolar disorder (BPD). METHOD We evaluated changes in suicidality ratings (Hamilton Depression Rating Scale item-3) at the start and after 3.59 +/- 2.57 months of sustained antidepressant treatment in a systematically assessed clinical sample (n = 789) of 605 patients with MDD, 103 patients with BPD-II and 81 patients with BPD-I (based on DSM-IV; 68.1% women; aged 44.3 +/- 16.1 years), comparing suicidal vs. non-suicidal and recovered vs. unrecovered initially suicidal patients. RESULTS Suicidal patients (103/789, 16.5%; BPD/MDD risk: 2.2) were more depressed and were ill longer. During treatment, 81.5% of suicidal patients became non-suicidal; 0.46% of 656 initially non-suicidal patients reported new suicidal thoughts, with no new attempts. Becoming non-suicidal was associated with greater depression severity and greater improvement. CONCLUSION Suicidal ideation was prevalent in patients with depressed major affective disorder, but most of the initially suicidal patients became non-suicidal with antidepressant treatment, independent of diagnosis, treatment type or dose.

Abstract
The primary objective of this study was to compare the effectiveness of combination treatment of valproate and amisulpride with that of valproate and haloperidol in bipolar I disorder. Adult inpatients with a current manic episode fulfilling DSM-IV-TR diagnostic criteria for bipolar type I disorder were included. Patients were randomized to amisulpride (400-800 mg/day) or haloperidol (5-15 mg/day) for 3 months and all received valproate. The primary effectiveness criterion was the percentage of responders (defined by a decrease of >/=50% of the Y-MRS) in patients completing the study. Safety was evaluated by adverse event reporting, determination of extrapyramidal function and clinical examination. Sixty-two patients were randomized to receive valproate-amisulpride, and 61 to receive valproate-haloperidol. At study end, responder rates were 72.6% in the amisulpride group and 65.5% in the haloperidol group. Remission rates were 83.9% and 89.7%, respectively. At study end, neither response rates nor remission rates differed significantly between groups. Treatment-emergent adverse events occurred significantly (p = 0.009) more frequently in the haloperidol group (86.4%) than in the amisulpride group (66.1%). In conclusion, the valproate-amisulpride combination was as effective as the valproate - haloperidol combination in bipolar I patients, with a better safety profile.

Abstract
We examined differences in treatments received, and attitudes and adherence to them between suicidal and nonsuicidal patients with major depressive disorder (MDD). Psychiatric MDD patients with no suicidal behavior (N = 92), suicidal ideation (N = 92), or attempts (N = 34) were compared during 6 months of follow-up in the Vantaa Depression Study (VDS). Patients with suicidal behavior received antidepressants or adequate antidepressant treatment significantly more often, had more frequent appointments with psychiatrists, more psychotherapeutic support, and more favorable attitudes toward antidepressant treatment than nonsuicidal patients. However, after adjusting for the confounding severity of depression, the significance of these differences was lost. Adherence to treatment was similar in the patient groups. Overall, among psychiatric patients with MDD, those known to be suicidal have higher suicide risk and should receive more intensive treatment. However, suicidal behavior per se does not seem to markedly influence treatments provided nor should it be associated with negative attitudes or poor adherence to treatments.

Abstract
The proportion of diagnosed depressives prescribed antidepressants has increased markedly over the last 20 years, mainly following the introduction of the selective serotonin reuptake inhibitors. However, currently available antidepressants have notable limitations, relating to their only moderate efficacy relative to placebo, relatively slow onset of action, possible withdrawal symptoms, and problems of compliance. Sleep disturbances are often used to identify newly presenting depressive patients, and may be part of a more general alteration of bodily rhythms. There are links between pharmacological treatments and circadian rhythms in depression, which might represent another, new option for the development of a therapeutic approach to depression treatment. Many antidepressants affect sleep, some are sedative, and others have been used specifically in severely insomniac depressives. Disturbances in circadian rhythms may be an integral part of depressive mechanisms, and normalising them via an innovative mechanism of antidepressant action may be a fruitful avenue in the search for improved antidepressant agents.

Abstract
OBJECTIVE We estimated risks of suicidal behaviors in 2826 mood-disorder patients evaluated and followed in a Sardinian mood disorders research center over the past 30 years. METHOD We determined rates of suicidal ideation, attempts, and suicides, with associated risk factors, in men and women with DSM-IV bipolar I (BP-I; n = 529), BP-II; (n = 314), or major depressive disorders (MDD; n = 1983), at risk for an average of 11 years of illness. RESULTS Observed rates (% of patients/year) of suicide ranked: BP-II (0.16) > or = BP-I (0.14) > MDD (0.05); attempts: BP-I (1.52) > BP-II (0.82) > MDD (0.48); ideation: BP-II (42.7) > MDD (33.8) > BP-I (22.7). The ratio of attempts/suicides (lethality index) ranked: BP-II (5.12) < MDD (9.60) < or = BP-I (10.8). Male/female risk-ratios were greater for suicide than attempts or ideation. One-third of all reported acts occurred within the first year of illness, and earliest among MDD patients. Factors associated independently with suicidal acts included BP diagnosis, hospitalizations/person, and early illness-onset; factors associated with suicidal ideation were having an affective temperament, BP-II diagnosis, and higher suicidality-corrected depression score at intake. CONCLUSION Suicidal behaviors were more prevalent among BPD than MDD out-patients.

Abstract
BACKGROUND Linkage of bipolar disorder to a broad region on chromosome 13q has been supported in several studies including a meta-analysis on genome scans. Subsequent reports have shown that variations in the DAOA (G72) locus on 13q33 display association with bipolar disorder but these may not account for all of the linkage evidence in the region. OBJECTIVE To identify additional susceptibility loci on 13q32-q33 by linkage disequilibrium mapping and explore the impact of phenotypic heterogeneity on association. METHODS In the initial phase, 98 single nucleotide polymorphism (SNPs) located on 13q32-q33 were genotyped on 285 probands with bipolar disorder and their parents were drawn from families in the NIMH Genetics Initiative consortium for bipolar disorder (NIMH1-4) and two other series. Fine scale mapping using one family series (NIMH1-2) as the test sample was targeted on a gene that displayed the highest evidence of association. A secondary analysis of familial component phenotypes of bipolar disorder was conducted. RESULTS Three of seven SNPs in DOCK9, a gene that encodes an activator of the Rho-GTPase Cdc42, showed significant excess allelic transmission (P=0.0477-0.00067). Fine scale mapping on DOCK9 yielded evidence of association at nine SNPs in the gene (P=0.02-0.006). Follow-up tests detected excess transmission of the same allele of rs1340 in two out of three other sets of families. The association signals were largely attributable to maternally transmitted alleles (rs1927568: P=0.000083; odds ratio=3.778). A secondary analysis of familial component phenotypes of bipolar disorder detected significant association across multiple DOCK9 markers for racing thoughts, psychosis, delusion during mania and course of illness indicators. CONCLUSION These results suggest that DOCK9 contributes to both risk and increased illness severity in bipolar disorder. We found evidence for the effect of phenotypic heterogeneity on association. To our knowledge this is the first report to implicate DOCK9 or the Rho-GTPase pathway in the etiology of bipolar disorder.

Abstract
INTRODUCTION Antipsychotics, particularly second generation agents, are widely used in bipolar disorder, but their effect on suicidal behavior in this population has not been systematically studied. METHODS Retrospective chart review of 405 veterans with bipolar disorder followed for a mean of three years, with month-by-month systematic assessment of current pharmacotherapy and suicide completion, attempt or hospitalization for suicidality. Comparison of rates of suicidal events during mood stabilizer monotherapy, antipsychotic monotherapy, and combination of mood stabilizer and antipsychotic. RESULTS Non-lethal suicide event rates were 9.4 times greater (chi2=28.29, p<.0001) during antipsychotic monotherapy and 3.5 times greater during mood stabilizer+antipsychotic (chi2=15.13, p=0.0001) than during mood stabilizer monotherapy. LIMITATIONS Antipsychotics may have been prescribed because patients were at greater risk of suicidal behavior. First and second generation antipsychotics were not distinguished. CONCLUSIONS Treatment of bipolar patients with antipsychotics is associated with an increase in non-lethal suicidal behavior. Thus, use of antipsychotics for bipolar patients requires careful monitoring for suicidal behavior. Further studies are urgently needed to better characterize this relationship.

Abstract
Epidemiological data suggest that between 59 and 87% of suicide victims suffered from major depression while up to 15% of these patients will eventually commit suicide. Male gender, previous suicide attempt(s), comorbid mental disorders, adverse life-situations, acute psycho-social stressors etc. also constitute robust risk factors. Anxiety and minor depression present with a low to moderate increase in suicide risk but anxiety-depression comorbidity increases this risk dramatically Contrary to the traditional psychoanalytic approach which considers suicide as a retrospective murder or an aggression turned in-wards, more recent studies suggest that the motivations to commit suicide may vary and are often too obscure. Neurobiological data suggest that low brain serotonin activity might play a key role along with the tryptophan hydroxylase gene. Social factors include social support networks, religion etc. It is proven that most suicide victims had asked for professional help just before committing suicide, however they were either not diagnosed (particularly males) or the treatment they received was inappropriate or inadequate. The conclusion is that promoting suicide prevention requires the improving of training and skills of both psychiatrists and many non-psychiatrists and especially GPs in recognizing and treating depression and anxiety. A shift of focus of attention is required in primary care to detect potentially suicidal patients presenting with psychological problems. The proper use of antidepressants, after a careful diagnostic evaluation, is important and recent studies suggest that successful acute and long-term antidepressant pharmacotherapy reduces suicide morbidity and mortality.

Abstract
OBJECTIVES To further test the hypothesis that past illness episodes and delay of long-term treatment do not limit maintenance treatment response among patients with manic-depressive illnesses (MDI). METHODS In a sample of 764 MDI patients in Cagliari and Berlin, 77% of whom had bipolar disorder (BPD), we: (i) correlated treatment latency or pretreatment episode counts versus hospitalized morbidity during treatment; (ii) correlated treatment duration versus pretreatment morbidity; (iii) correlated treatment latency versus pretreatment or treated morbidity; (iv) modeled factors associated with longer treatment latency; (v) compared treatment latencies at extremes of treatment outcomes, and (vi) compared pretreatment morbidity within 2 years of the longest versus shortest treatment latency quartiles. RESULTS Pretreatment morbidity was strongly correlated with shorter treatment latency, but morbidity during treatment was unrelated to treatment latency, pretreatment episode counts, sex, diagnosis, treatment type or treatment duration. In multivariate modeling, treatment latency was longer among patients who had experienced an early onset of illness, mainly in depressive disorders (BPD II and major depression) and among women, but was unrelated to morbidity during treatment. Patients with no illness recurrences during treatment and those who were ill at least 50% of the time had similar treatment latencies. Pretreatment morbidity occurring just prior to the initiation of long-term treatment was very similar at the highest and lowest treatment latencies. CONCLUSIONS These findings support the therapeutically favorable conclusion that prior episode counts and treatment delay have little association with morbidity during prophylaxis with mood-stabilizing agents. Comparisons of morbidity during versus before treatment in episodic disorders are misleading because overall morbidity becomes diluted with longer time-at-risk, whereas therapeutic intervention is typically determined by immediately preceding illness.

Abstract
Individuals with bipolar disorder are at increased risk for suicide attempts and completion. Although anxiety may be a modifiable suicide risk factor among bipolar patients, anxiety disorder comorbidity has not been highlighted as critical in identification of high-risk individuals nor has its treatment been integrated into suicide prevention strategies. In this study, ancillary to the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD), 120 outpatients with bipolar disorder completed detailed assessment of suicidal ideation and behaviors. We examined the association of current and lifetime comorbid anxiety disorders with suicidal ideation and behaviors univariately and with adjustment for potential confounders in regression models. Lifetime anxiety disorders were associated with a more than doubling of the odds of a past suicide attempt, and current anxiety comorbidity was associated with a more than doubling of the odds of current suicidal ideation. Individuals with current anxiety disorders had more severe suicidal ideation, a greater belief suicide would provide relief, and a higher expectancy of future suicidal behaviors. However, some of these associations appeared to be better accounted for by measures of bipolar severity including an earlier age at bipolar onset and a lack of current bipolar recovery. Comorbid anxiety disorders may play a role in characteristics of bipolar disorder that then elevate risk for suicidal ideation and attempts. While further research is needed to establish the precise nature of these associations, our data support that the presence of comorbid anxiety disorders in individuals with bipolar disorder should trigger careful clinical assessment of suicide risk.

Abstract
OBJECTIVE This study aimed to determine the associations between guideline-concordant pharmacotherapy for depression and the use of health services in the year following diagnosis. METHOD This population-based, retrospective cohort study examined Quebec drug plans between 1999 and 2002. We included beneficiaries aged 18 to 64 years who were newly diagnosed with an episode of depression by primary care physicians and psychiatrists between October 1, 2000, and March 31, 2001, and who made at least one psychotropic pharmacy claim within 31 days of diagnosis. We defined guideline concordance as the receipt of recommended medication, starting dosage, and treatment duration as defined by the Canadian Network for Mood and Anxiety Treatments guidelines. We measured outcomes on use of ambulatory (number of visits to prescribing physician, other physicians, or emergency departments) and inpatient (hospitalization) services. RESULTS There were 2742 patients (mean age 42 years; 64% female patients) who met the study criteria. Of the 2047 (75%) patients to whom an antidepressant was dispensed, 1958 (71%) received a recommended first-line medication, 1297 (63%) received a recommended starting dosage, and 304 (15%) received a recommended duration. According to the 3 criteria, only 8% were treated appropriately; 21% received benzodiazepines rather than antidepressants. There were 2 median visits (inferquartile range [IQR] 1 to 3) to prescribing physicians, 0 visits (IQR 0 to 1) to other physicians, and 0 visits (IQR 0 to 0) to emergency departments; 497 (18%) patients were hospitalized. In separate multivariate models for repeated measures, recommended first-line medication, dosage, and duration were associated with more prescribing physician visits. Recommended first-line medication reduced the odds of hospitalization. CONCLUSION Guideline concordance was associated with more visits to prescribing physicians and lower odds of hospitalization.

Abstract
Background. Recent preclinical research suggests that lithium, clozapine, and possibly even antidepressants, have neurotrophic and neuroprotective properties. However, it remains unclear whether their long-term use can prevent the development of dementia or attenuate its severity in patients with major mood disorders. Method. Subjects included patients with bipolar disorder (N=220) and major depressive disorder (N=186) admitted between 1959 and 1963 and followed from 1965 to 1985. The presence of dementia was assessed clinically using ICD-9 criteria, and functioning was determined with the Global Assessment Schedule (GAS). Long-term medication with lithium, clozapine and antidepressants was documented. Results. In the total sample, the occurrence of dementia correlated only with age. In a restricted analysis of the 88 patients with dementia, age became non-significant and lithium showed a trend to an inverse correlation with the severity of dementia. In the subgroup of bipolar demented patients, both lithium and clozapine medication were inversely related to the severity of dementia. Conclusions. The results are consistent with an attenuating effect of lithium and possibly clozapine on the development of severe dementia. Limitations. The sample of patients with dementia was small and the results are based on a naturalistic study. Dementia was only assessed once, without the use of cognitive measures.

Abstract
PURPOSE OF REVIEW The aim of this review is to highlight the traditional and newly recognized suicide risk factors in patients with mood disorders. RECENT FINDINGS Current research findings clearly suggest that suicidal behaviour in patients with mood disorder is a 'state-dependent' phenomenon. Recently, there is, however, a growing body of evidence that besides the well accepted clinically explorable suicide risk factors in mood disorders (e.g., severe depression, prior suicide attempt, comorbid anxiety, substance use, personality disorders and so on), mixed state of depression could also be an important precursor of suicidal behaviour. This might be particularly true in unrecognized cases of bipolar depressives, when antidepressant monotherapy (unprotected by mood stabilizers or atypical antipsychotics) can worsen the clinical picture and rarely induce an aggressive or self-destructive behaviour. SUMMARY In the majority of patients with mood disorders, suicidal behaviour is predictable and preventable, with a good chance. A careful and systematic exploration of suicide risk factors in patients with mood disorder helps clinicians to identify patients at high suicide risk. A successful, acute and long-term treatment of these patients substantially reduces the suicidal behaviour even in this high-risk population.

Abstract
Bipolar disorder (BD) is a prevalent condition in the United States that typically begins before the age of 18 years and is being increasingly recognized in children and adolescents. Despite great efforts in discovering more effective treatments for BD, it remains a difficult-to-treat condition with high morbidity and mortality. Therefore, it appears prudent to focus energies into developing interventions designed to prevent individuals from ever fully developing BD. Such interventions early in the development of the illness might prevent inappropriate interventions that may worsen or hasten development of BD, delay the onset of first manic episode, and/or prevent development of full BD. Studies of populations at high-risk for BD development have indicated that children with strong family histories of BD, who are themselves experiencing symptoms of attention-deficit/hyperactive disorder (ADHD) and/or depression or have early mood dysregulation, may be experiencing prodromal states of BD. Understanding the neurobiological and genetic underpinnings that create risk for BD development would help with more accurate identification of this prodromal population, which could then lead to suitable preventative interventions. Such interventions could be pharmacologic or psychosocial in nature. Reductions in stress and increases in coping abilities through psychosocial interventions could decrease the chance of a future manic episode. Similarly, psychotropic medications may decrease negative sequelae of stress and have potential for neuroprotective and neurogenic effects that may contribute to prevention of fully expressed BD. Further research into the biologic and environmental mechanisms of BD development as well as controlled early intervention studies are needed to ameliorate this significant public health problem.

Abstract
In 2005, the Canadian Network for Mood and Anxiety Treatments (CANMAT) published guidelines for the management of bipolar disorder. This update reviews new evidence since the previous publication and incorporates recommendations based on the most current evidence for treatment of various phases of bipolar disorder. It is designed to be used in conjunction with the 2005 CANMAT Guidelines. The recommendations for the management of acute mania remain mostly unchanged. Lithium, valproate and several atypical antipsychotics continue to be recommended as first-line treatments for acute mania. For the management of bipolar depression, new data support quetiapine monotherapy as a first-line option. Lithium and lamotrigine monotherapy, olanzapine plus selective serotonin reuptake inhibitors (SSRI), and lithium or divalproex plus SSRI/bupropion continue to remain the other first-line options. First-line options in the maintenance treatment of bipolar disorder continue to be lithium, lamotrigine, valproate and olanzapine. There is recent evidence to support the combination of olanzapine and fluoxetine as a second-line maintenance therapy for bipolar depression. New data also support quetiapine monotherapy as a second-line option for the management of acute bipolar II depression. The importance of comorbid psychiatric and medical conditions cannot be understated, and this update provides an expanded look at the prevalence, impact and management of comorbid conditions in patients with bipolar disorder.

Abstract
Patients with bipolar disorder are at very high risk for suicidal ideation, non-fatal suicidal behaviors and suicide and are frequently treated with antidepressants. However, no prospective, randomized, controlled study specifically evaluating an antidepressant on suicidality in bipolar disorder has yet been completed. Indeed, antidepressants have not yet been shown to reduce suicide attempts or suicide in depressive disorders and may increase suicidal behavior in pediatric, and possibly adult, major depressive disorder. Available data on the effects of antidepressants on suicidality in bipolar disorder are mixed. Considerable research indicates that mixed states are associated with suicidality and that antidepressants, especially when administered as monotherapy, are associated with both suicidality and manic conversion. In contrast, growing research suggests that antidepressants administered in combination with mood stabilizers may reduce depressive symptoms in patients with bipolar depression. Further, the only prospective, long-term study evaluating antidepressant treatment and mortality in bipolar disorder, although open-label, found antidepressants and/or antipsychotics in combination with lithium, but not lithium alone, reduced suicide in bipolar and unipolar patients (Angst F, et al. J Affect Disord 2002: 68: 167-181). We conclude that antidepressants may induce suicidality in a subset of persons with depressive (and probably anxious) presentations; that this induction may represent a form of manic conversion, and hence a bipolar phenotype, and that lithium's therapeutic properties may include the ability to prevent antidepressant-induced suicidality.

Abstract
OBJECTIVES To update and extend comparisons of rates of suicides and suicide attempts among patients with major affective disorders with versus without long-term lithium treatment. METHODS Broad searching yielded 45 studies providing rates of suicidal acts during lithium treatment, including 34 also providing rates without lithium treatment. We scored study quality, tested between-study variance, and examined suicidal rates on versus off lithium by meta-analytic methods to determine risk ratios (RRs) and 95% confidence intervals (CI). RESULTS In 31 studies suitable for meta-analysis, involving a total of 85,229 person-years of risk-exposure, the overall risk of suicides and attempts was five times less among lithium-treated subjects than among those not treated with lithium (RR = 4.91, 95% CI 3.82-6.31, p < 0.0001). Similar effects were found with other meta-analytic methods, as well as for completed versus attempted suicide, and for bipolar versus major mood disorder patients. Studies with higher quality ratings, including randomized, controlled trials, involved shorter exposures with somewhat lesser lithium superiority. Omitting one very large study or those involving lithium-discontinuation had little effect on the results. The incidence-ratio of attempts-to-suicides increased 2.5 times with lithium-treatment, indicating reduced lethality of suicidal acts. There was no indication of bias toward reporting positive findings, nor were outcomes significantly influenced by publication-year or study size. CONCLUSIONS Risks of completed and attempted suicide were consistently lower, by approximately 80%, during treatment of bipolar and other major affective disorder patients with lithium for an average of 18 months. These benefits were sustained in randomized as well as open clinical trials.

Abstract
OBJECTIVES Bipolar patients are at high risk for suicidal ideation and attempts. Suicidal behavior is correlated with poor family communication and/or high levels of intrafamilial conflict, particularly among adolescent bipolar patients. This article describes the application of family-focused therapy (FFT) as an adjunct to pharmacotherapy in the management of suicidal ideation and behavior among bipolar patients. METHODS We describe the empirical basis of FFT in studies of adult and adolescent patients. We then describe the manner by which the three modules of FFT - psychoeducation, communication skills training and problem solving - are adapted to address the clinical issues presented by suicidal bipolar adults or adolescents and their families. RESULTS Key objectives of the treatment are to help the family recognize that suicidal behavior is a part of the pathophysiology of bipolar disorder but that it is also to some extent under environmental control. Thus, the family is in a unique position to develop and help assure the success of a suicide prevention contract. A case study of an adolescent with suicidal behavior is presented. CONCLUSIONS Future research should include a focus on: (i) cross-cultural issues in suicide and bipolar disorder; and (ii) the adaptation of interventions shown to be effective in reducing suicidal behaviors in non-bipolar populations.

Abstract
What have you heard or read over the past 10 years that has improved you ability to assess and manage suicide risk in your patients?There has been a paucity of data. What little data there is reviewed in this month's articles.They highlight findings that you should know about. Clinicians seem to cling to the familiar, unless some intense marketing is done.For instance, are you aware that the current evidence shows that a denial of suicide thoughts, plans, or intent—even a contract for safety—means absolutely nothing in the absence of a full suicide risk assessment?Yet clinicians seem to rely on these ’reassurances“ from their patients and are shocked when the patient later commits suicide. Why should a patient who is deciding that life is too painful to live tell you the truth? Robert I. Simon, MD, and Daniel W. Shuman, JD, review these facts.Are you aware that severe psychic anxiety, panic attacks, agitation, and severe insomnia often precede suicide within hours, days, or weeks and can be rapidly modified with treatment?On the other hand, standard risk factors for suicide such as suicidal ideation, hopelessness, and past suicidal attempts are not good predictors of suicide in the short term. A suicide plan, recent high intent attempt, or refusal to contract for safety may well indicate immediate risk, but a denial of suicidal ideation or intent and a contract for no harm mean absolutely nothing without a full suicide assessment that takes current clinical status, past suicidal tendencies, social support, and willingness to accept help into account.

Abstract
The range of available antidepressants is reviewed in relation to mechanisms of action and the evidence of efficacy in general and efficacy in severe depression in particular. In studies investigating efficacy in major depressive disorder, not all antidepressants have been shown to have clear-cut efficacy in severe depression. Here, the minimum standards for the necessary methodology to investigate efficacy in severe depression are reviewed and the methods that are needed to establish efficacy as a superior antidepressant or as an antidepressant with a faster than expected response are suggested. A review of the mechanisms of action of different antidepressants is accompanied by a critical review of the properties of an antidepressant likely to achieve either efficacy in severe depression or the status of a superior antidepressant.

Abstract
In this chapter we review research on the diagnosis, course, etiology, and pharmacological and psychosocial treatment of bipolar disorder (BD). BD is a highly recurrent and severe illness, with high rates of suicidality and functional impairment. The disorder is heritable and appears to share susceptibility genes with schizophrenia. It is characterized by dysregulation in the dopamine and serotonin systems and by pathology in the brain systems involved in regulating emotion. Psychosocial stressors, notably life events and familial expressed emotion, significantly influence the course of the illness in the context of these vulnerabilities. Findings of randomized clinical trials indicate that psychosocial interventions enhance long-term outcomes when added to pharmacotherapy. Much remains to be clarified about the interactive contributions of genetic, neurobiological, and psychosocial factors to the course of the disorder, and the moderators and mediators of treatment effects.

Abstract
Depression is a highly disabling, recurrent disease that imposes a significant burden on the individual, their close contacts, and on society. Despite the existence of treatment guidelines for major depression, management frequently falls short of these recommendations, sometimes due to inadequate doses or duration of prescribed antidepressant medication; at other times secondary to patient non-adherence to the recommended treatment. Evidence-based treatment guidelines developed by the major mental health organizations advise that patients who have experienced either a first or a recurrent episode of major depression should receive continued therapeutic doses of medication for at least 4-6 months following symptom remission, to reduce the risk of relapse. Further to this, antidepressant prophylaxis is beneficial in any patient with a history of three or more major depressive episodes, or two or more episodes in the last 5 years. Selective serotonin reuptake inhibitors (SSRIs) have demonstrated excellent efficacy and tolerability in the treatment and prophylaxis of major depression, as well as being associated with significant reduction in suicide risk in some populations. Escitalopram, an atypical SSRI that has shown superiority to conventional SSRIs and venlafaxine in clinical studies, has demonstrated particular benefits in severely depressed patients, in whom its efficacy appears to increase with increasing severity of depression. In the absence of formal treatment guidelines for severe depression, or comborbid depression and anxiety, escitalopram appears to be a logical treatment choice.

Abstract
This study was designed to develop models for vulnerability to suicidal ideation in bipolar patients. Logistic regression models examined correlates of suicidal ideation in patients who had versus had not attempted suicide previously. Of 477 patients assessed, complete data on demographic, illness history, and personality variables were available on 243. The regression models achieved positive predictive values of 55% and 59% for the attempter (N = 92) and nonattempter groups (N = 151), respectively. Depression was cross-sectionally associated with suicidal ideation in both the attempter and nonattempter groups but made a smaller contribution among attempters. Poor psychosocial adaptation and the personality factor "openness" were stronger contributors to suicidal ideation among prior attempters while anxiety and extraversion appeared protective against ideation. Among nonattempters, depression, anxiety, and neuroticism were the predominant influences on suicidal ideation. Bipolar patients with suicidal ideation may benefit from different treatment strategies depending on their prior attempt status.

Abstract
Lifestyle, illness and treatment factors in people with bipolar disorder (BD) may confer additional risk of morbidity and mortality to the increasing rates of obesity, metabolic syndrome, diabetes mellitus and cardiovascular mortality in the general population.The aim of this review is to examine whether the risk of obesity and related morbidity and mortality are raised in BD, and possible contributory effects of lifestyle, illness and treatment factors to this risk.Systematic search of Medline and Cochrane Collaboration for relevant studies followed by a critical review of literature was carried out.Mortality from cardiovascular causes and pulmonary embolism (standardized mortality ratio approximately 2.0), and morbidity from obesity and type 2 diabetes mellitus may be increased in BD compared to the general population. Reduced exercise and poor diet, frequent depressive episodes, comorbidity with substance misuse and poor quality general medical care contribute to the additional risk of these medical problems in people with BD. There is no evidence that patients with BD are more sensitive than other patients to weight gain and medical problems associated with long-term use of psychotropic medication; in fact long-term treatment with lithium, antipsychotics and tricyclic antidepressants may reduce overall mortality. Psychiatrists, general practitioners and other health professionals should work together to systematically assess and manage weight gain and related medical problems to reduce the morbidity and mortality associated with obesity in BD. There is insufficient evidence to associate any of these factors with specific drug treatments. More research is required to understand how BD changes the risk for physical health comorbidity.

Abstract
Although the existence of mood disorders was identified centuries ago, the present state of knowledge is unsatisfactory. This special issue of Archives of Suicide Research (ASR), the official journal of the International Academy for Suicide Research, presents the state of the science and collects new empirical data. Different aspects of suicidality in bipolar and bipolar spectrum disorders are outlined and the prophylactic aspects of pharmacotherapy are noted, especially the anti-suicide effect of lithium. A call for further study is, however, necessary.
