Chakrabarti S, Singh N. Psychotic symptoms in bipolar disorder and their impact on the illness: A systematic review. World J Psychiatry 2022; 12:1204-1232. [PMID: 36186500 PMCID: PMC9521535 DOI: 10.5498/wjp.v12.i9.1204] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Revised: 05/02/2022] [Accepted: 08/26/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Lifetime psychotic symptoms are present in over half of the patients with bipolar disorder (BD) and can have an adverse effect on its course, outcome, and treatment. However, despite a considerable amount of research, the impact of psychotic symptoms on BD remains unclear, and there are very few systematic reviews on the subject.
AIM To examine the extent of psychotic symptoms in BD and their impact on several aspects of the illness.
METHODS The Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed. An electronic literature search of six English-language databases and a manual search was undertaken to identify published articles on psychotic symptoms in BD from January 1940 to December 2021. Combinations of the relevant Medical Subject Headings terms were used to search for these studies. Articles were selected after a screening phase, followed by a review of the full texts of the articles. Assessment of the methodological quality of the studies and the risk of bias was conducted using standard tools.
RESULTS This systematic review included 339 studies of patients with BD. Lifetime psychosis was found in more than a half to two-thirds of the patients, while current psychosis was found in a little less than half of them. Delusions were more common than hallucinations in all phases of BD. About a third of the patients reported first-rank symptoms or mood-incongruent psychotic symptoms, particularly during manic episodes. Psychotic symptoms were more frequent in bipolar type I compared to bipolar type II disorder and in mania or mixed episodes compared to bipolar depression. Although psychotic symptoms were not more severe in BD, the severity of the illness in psychotic BD was consistently greater. Psychosis was usually associated with poor insight and a higher frequency of agitation, anxiety, and hostility but not with psychiatric comorbidity. Psychosis was consistently linked with increased rates and the duration of hospitalizations, switching among patients with depression, and poorer outcomes with mood-incongruent symptoms. In contrast, psychosis was less likely to be accompanied by a rapid-cycling course, longer illness duration, and heightened suicidal risk. There was no significant impact of psychosis on the other parameters of course and outcome.
CONCLUSION Though psychotic symptoms are very common in BD, they are not always associated with an adverse impact on BD and its course and outcome.

Abstract
Psychotic episodes occur in a substantial proportion of patients suffering from major mood disorders (both unipolar and bipolar) at some point in their lives. The nature of these episodes is less well understood than the more common, non-psychotic periods of illness and hence their management is also less sophisticated. This is a concern because the risk of suicide is particularly high in this subtype of mood disorder and comorbidity is far more common. In some cases psychotic symptoms may be signs of a comorbid illness but the relationship of psychotic mood to other forms of psychosis and in particular its interactions with schizophrenia is poorly understood. Therefore, our targeted review draws upon extant research and our combined experience to provide clinical context and a framework for the management of these disorders in real-world practice - taking into consideration both biological and psychological interventions.

Abstract
OBJECTIVE To determine clinical predictors of lithium response in bipolar disorder. METHODS Systematic review of studies examining clinical predictors of lithium response was conducted. Meta-analyses were performed when ≥2 studies examined the same potential predictor. RESULTS A total of 71 studies, including over 12 000 patients, identified six predictors of good response: mania-depression-interval sequence [odds ratio (OR): 4.27; 95% CI: 2.61, 6.97; P < 0.001], absence of rapid cycling (OR for rapid cycling: 0.30; 95% CI: 0.17, 0.53; P < 0.001), absence of psychotic symptoms (OR for psychotic symptoms: 0.52; 95% CI: 0.34, 0.79; P = 0.002), family history of bipolar disorder (OR: 1.61; 95% CI: 1.03, 2.52; P = 0.036), shorter prelithium illness duration [standardised mean difference (SMD): -0.26; 95% CI: -0.41, -0.12; P < 0.001] and later age of onset (SMD: 0.17; 95% CI: 0.02, 0.36; P = 0.029). Additionally, higher body mass index was associated with poor response in two studies (SMD: -0.61; 95% CI: -0.90, -0.32; P < 0.001). There was weak evidence for number of episodes prior to lithium treatment (SMD: -0.42; 95% CI: -0.84, -0.01; P = 0.046), number of hospitalisations before lithium (SMD: -0.40; 95% CI: -0.81, 0.01; P = 0.055) and family history of lithium response (OR: 10.28; 95% CI: 0.66, 161.26; P = 0.097). CONCLUSIONS The relative importance of these clinical characteristics should be interpreted with caution because of potential biases and confounding.

Abstract
Patients with bipolar mania often require re-hospitalization, which can be a social-economic burden. This study aimed to investigate the factors affecting time to re-hospitalization for inpatients with acute bipolar mania. In this 6-year naturalistic study we reviewed the charts of inpatients with acute bipolar mania. Potential dichotomous factors including sex, family history of affective disorder, suicide history, and discharge against medical advice, involuntary admission, psychotic features, substance use disorder, and remission at discharge were recorded. Continuous variables including age, age at onset of affective episodes, and number of previous hospitalizations were also recorded. We used survival analysis with a univariate Cox proportional hazard regression model, along with forward multivariate model, to identify the potential factors. Of the 165 patients, 23% achieved symptomatic remission at discharge. In the forward Cox model, psychotic features, discharge against medical advice and higher number of previous hospitalizations were significant risk factors for re-admission. Remission at discharge was significantly associated with preventing re-hospitalization. We identified several predictors for re-hospitalization among inpatients with bipolar mania. Further studies are needed in other real-world settings to validate our results.

Abstract
OBJECTIVES To evaluate the effect of psychosis on prognosis as measured by the course of a manic episode, symptoms severity and time to remission and identify existing differences in positive and negative symptoms between psychotic and non-psychotic patients. STUDY DESIGN 40 bipolar patients presenting with a diagnosis of acute mania were enrolled (18 psychotic patients and 22 non-psychotic patients) in this cross-sectional study. Subjects were required to complete two self-reported questionnaires, the Young Mania Rating Scale (YMRS) for manic symptoms, and Positive and Negative Symptoms Scale (PANSS) for psychotic symptoms. Rating scales were administered at baseline and then again after three weeks of pharmacologic treatment. RESULTS There were no differences in socio-demographic characteristics between psychotic and non-psychotic subjects. Psychosis was associated with higher scores on the YMRS and PANSS (increased symptoms severity), compared to non-psychotic patients. Both groups demonstrated clinical improvement and remission, with scores amongst psychotic patients remaining higher. Groups were similar in symptomatology except with regards to psychotic symptoms (the content, insight, delusions, hallucinations, grandiosity, poor rapport and unusual thoughts). CONCLUSIONS Psychosis can be considered a severity index in bipolar disorder, with decreased severity and overall clinical improvement and remission taking place in response to pharmacotherapy.

Abstract
BACKGROUND Bipolar disorder is a complicated and chronic mental disorder. This study investigated factors affecting time to remission for inpatients with bipolar mania after 4 weeks of acute treatment. METHODS This naturalistic study recruited inpatients with bipolar mania for acute treatment. Symptom severity was assessed using the Young Mania Rating Scale (YMRS) at weeks 0, 1, 2, 3, and 4. Patients were included if they had had assessments at weeks 0 and 1 Remission was defined as an YMRS score ≤ 12. The Cox regression analysis was used to analyze factors associated with time to remission after 4 weeks of acute treatment. RESULTS Four hundred and forty-nine patients entered the analysis. Seventy-one of the 449 subjects (15.8%) reached symptomatic remission within 4 weeks of acute treatment. Using forward multivariate Cox regression analysis, comorbid substance use disorders, earlier age at onset, and greater manic symptom severity at baseline found to be statistically significant predictors of a longer time to reach remission after 4 weeks of treatment. LIMITATIONS As a retrospective chart review and naturalistic design, placebo effect and potentially confounding factors such as the possibility of missing records may have limited our results. CONCLUSIONS Early identification and intervention with integrated therapy is considered to shorten time to remission for patients at high risk of poor treatment outcome. More studies are needed in other real-world settings to generalize our results.

Efficacy, safety and tolerability of aripiprazole in bipolar disorder: An updated systematic review and meta-analysis of randomized controlled trials. Prog Neuropsychopharmacol Biol Psychiatry 2017; 79:289-301.

Abstract
Numerous studies have investigated aripiprazole as a treatment for bipolar disorder (BD). therefore we conducted this comprehensive meta-analysis to investigate the efficacy and safety profile of aripiprazole in treating BD. Two authors conducted systematic searches of PubMed and ScienceDirect from inception until May 14th, 2017. Randomized controlled trials (RCTs) of people with BD who received aripiprazole were included. A total of 20 RCTs met the eligibility criteria, including two which investigated the efficacy of aripiprazole versus haloperidol (aripiprazole=340; haloperidol=337), three which compared aripiprazole versus lithium (aripiprazole=208; lithium=212), and 15 with multiple comparisons of aripiprazole versus a placebo (aripiprazole=1923; placebo=1499). Compared to a placebo, aripiprazole improved acute mania (Hedges' g: -0.299, p=0.001) and psychosis (Hedges' g: -0.296, p<0.001) in the acute mania state, but did not improve depressive symptoms (Hedges' g: -0.127, p=0.054) in the acute depressive state. Aripiprazole was associated with lower relapse rates in bipolar mania when used in combination versus a placebo in maintenance therapy (odds ratio: 0.522, p<0.029). Aripiprazole was also associated with higher levels of high density lipoprotein, lower dropout rates, but no difference in extrapyramidal symptoms in the maintenance phase versus a placebo or in comparison with other medications (haloperidol or lithium). Our results suggest that aripiprazole is effective and safe in treating bipolar mania. Further trials are necessary to evaluate the efficacy and tolerability versus other medications.

Abstract
INTRODUCTION Prospective studies have shown that the course of bipolar disorder (BD) is characterized by the persistence of symptoms, predominantly depression, along most of the time. However, to our knowledge, no studies in Latin America have investigated it. OBJECTIVES To replicate international studies using a Brazilian sample to prospectively analyze treatment outcomes in the first year and to determine potential chronicity factors. METHODS We followed up 102 patients with BD for 12 months and evaluated the number of months with affective episodes and the intensity of manic and depressive symptoms using the Young Mania Rating Scale (YMRS) and the Hamilton Depression Scale (HAM-D17). Sociodemographic and retrospective clinical data were examined to determine possible predictors of outcome. RESULTS Almost 50% of the patients had symptoms about half of the time, and there was a predominance of depressive episodes. Disease duration and number of depressive episodes were predictors of chronicity. Depressive polarity of the first episode and a higher number of depressive episodes predicted the occurrence of new depressive episodes. CONCLUSION In general, BD outcome seems to be poor in the first year of monitoring, despite adequate treatment. There is a predominance of depressive symptoms, and previous depressive episodes are a predictor of new depressive episodes and worse outcome.

Abstract
Recent cognitive, genetic, and histological studies have highlighted significant overlap between psychotic bipolar disorder and schizophrenia. Specifically, both bipolar disorder and schizophrenia are characterized by interneuron dysfunction within the hippocampus, an essential structure for relational memory. Relational memory impairments are a common feature of schizophrenia, but have yet to be investigated in psychotic bipolar disorder. Here, we tested the hypothesis that psychotic bipolar disorder is characterized by relational memory deficits. We used a transitive inference (TI) paradigm, previously employed to quantify relational memory deficits in schizophrenia, to assess relational memory performance in 17 patients with psychotic bipolar disorder and 22 demographically matched control participants. Functional magnetic resonance imaging was used to examine hippocampal activity during recognition memory in patients and controls. Hippocampal volumes were assessed by manual segmentation. In contrast to our hypothesis, we found similar TI performance, hippocampal volume, and hippocampal recruitment during recognition memory in both groups. Both psychotic bipolar disorder patients and controls exhibited a positive correlation between hippocampal volume and relational memory performance. These data indicate that relational memory impairments are not a shared feature of non-affective and affective psychosis.

Abstract
OBJECTIVE In this study, we aimed to compare the clinical features and response patterns to the long-term prophylaxis of bipolar patients with or without psychotic features. METHOD The life charts of patients with bipolar I disorder were evaluated. Two hundred and eighty-one patients who suffer with bipolar disorder for at least 4 years and who had at least three mood episodes were included to the study. The patients whose all episodes are psychotic (psychotic group) and the patients who never experienced psychotic episode (non-psychotic group) were assigned as comparison groups. The clinical features and the response to long-term prophylaxis were compared across the groups. RESULTS The psychotic group consists of 43 patients; non-psychotic group consists of 54 patients. The history of bipolar disorder among the first-degree relatives was remarkably more prevalent in non-psychotic group (p=0.032). The predominance of manic/hypomanic episodes was significantly higher in psychotic group than non-psychotic group; and the rate of depressive episodes were higher in non-psychotic group than psychotic group (p=0.013). Episodes were more severe (p<0.001) and hospitalization rates were higher (p=0.023) in psychotic group. The response to lithium monotherapy was better in non-psychotic group (p<0.001). CONCLUSION The well identified psychotic subtype of bipolar patients may give important predictions about long term course and prophylaxis of bipolar disorder.

Abstract
BACKGROUND Psychosis has been identified in as many as 68% of patients with bipolar mania. This analysis identified psychotic symptoms in these patients. METHODS Data were from two placebo-controlled, 3-week studies in patients with an acute episode of bipolar mania. Symptoms were identified by the 30-item Positive and Negative Syndrome Scale (PANSS; item ratings, 1 = absent to 7 = extremely severe), the Young Mania Rating Scale, and the Global Assessment Scale. RESULTS Psychotic features at study entry were diagnosed in 264 (51.3%) of the 515 patients. At baseline, these patients had significantly more severe scores on the PANSS, Young Mania Rating Scale, and Global Assessment Scale than patients without psychotic features. Patients with psychotic features had mean (+/-SD) scores of mild (3) or greater on six PANSS items: grandiosity (4.5+/-1.4), delusions (4.4+/-1.4), lack of judgment/insight (4.1+/-1.5), excitement (3.9+/-1.3), suspiciousness/persecution (3.1+/-1.6), and hostility (3.1+/-1.5). Grandiosity symptoms of delusional proportions (scores > or = 4) were noted in 205 (78%) of patients with a diagnosis of psychotic features and in 113 (45%) patients without the diagnosis. LIMITATIONS The study was not specifically designed to assess patients with psychotic features and the PANSS was developed to evaluate symptoms of schizophrenia. CONCLUSIONS These findings support prior reports indicating high rates of psychosis in patients with bipolar mania and identify the most prominent symptoms in these patients.

Abstract
Previous research is inconsistent regarding the significance of mood-incongruent psychotic symptoms in relation to the severity and course of bipolar disorder. In the present study, bipolar I patients were assessed at index hospitalization using standardized symptom measures and followed up to 28 months. We contrasted the symptomatic course in patients experiencing mood-congruent versus mood-incongruent psychotic symptoms. Results revealed that patients spent an average of 29% of the time during follow-up in a mood episode, but only 5% of the time with psychotic symptoms. Few differences were found at the index hospitalization and no differences were found on any longitudinal course variables between mood-congruence subtypes. Although experiencing high levels of psychosis at baseline, both subtypes improved considerably following hospitalization, and psychotic symptom levels remained relatively stable. Current results suggest that when provided efficacious treatment, mood-incongruent psychotic mania does not predict a worse symptomatic course of illness.

Abstract
Bipolar Disorders affect up to 5% of the population. While the pharmacological options for the treatment of bipolar disorder have expanded over the past several years, lithium remains an inexpensive and efficacious treatment for bipolar disorder. Lithium has been demonstrated to be an effective treatment for acute mania, bipolar depression, the prophylactic treatment of bipolar disorder, and as an augmentation agent in the treatment of unipolar major depression. Lithium also is the only mood stabilizer that has been demonstrated to lower the suicide rate in patients with bipolar disorder. Use in special populations, side effects and toxicity, and drug interactions are discussed. Important laboratory monitoring guidelines are included in this review. Lithium remains an important intervention for the treatment of mood disorders.

Abstract
OBJECTIVES The aim of this study was to systematically integrate the available evidence on response prediction to prophylactic lithium based on clinical factors. METHODS Each clinical variable that was related to lithium response in at least one prior study was examined with respect to response prediction. If several studies were located for the same variable, results were integrated using the meta-analytic approach as suggested by DerSimonian and Laird which was developed for substantial heterogeneity in primary studies. RESULTS Of 42 potential clinical predictors investigated, five variables were identified as possible response predictors of prophylactic lithium: [1] An episodic pattern of mania-depression-interval, and [2] a high age of illness onset were identified as potentially protective against a recurrence under lithium. [3] A high number of previous hospitalizations, [4] an episodic pattern of depression-mania-interval, and [5] continuous cycling were identified as potential risk factors. Six further variables were found to be significantly related to lithium response, though calculation of fail-safe numbers indicates that current evidence is not sufficient to hold these variables as reliable predictors of lithium response. All effect-sizes relating clinical predictors to response were small to moderate. CONCLUSIONS Although a few variables are quite robustly supported as response-predictors in this review, a more in-depth analysis of each potential predictor is needed. As none of the potential predictors had a very strong impact on response, prediction of lithium response should be based on a multitude of variables.

Abstract
The effects of chronic lithium administration on regional brain incorporation coefficients k* of arachidonic acid (AA), a marker of phospholipase A2 (PLA2) activation, were determined in unanesthetized rats administered i.p. saline or 1 mg/kg i.p. (+/-)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane hydrochloride (DOI), a 5-HT2A/2C receptor agonist. After injecting [1-(14)C]AA intravenously, k* (brain radioactivity/integrated plasma radioactivity) was measured in each of 94 brain regions by quantitative autoradiography. Studies were performed in rats fed a LiCl or a control diet for 6 weeks. In the control diet rats, DOI significantly increased k* in widespread brain areas containing 5-HT2A/2C receptors. In the LiCl-fed rats, the significant positive k* response to DOI did not differ from that in control diet rats in most brain regions, except in auditory and visual areas, where the response was absent. LiCl did not change the head turning response to DOI seen in control rats. In summary, LiCl feeding blocked PLA2-mediated signal involving AA in response to DOI in visual and auditory regions, but not generally elsewhere. These selective effects may be related to lithium's therapeutic efficacy in patients with bipolar disorder, particularly its ability to ameliorate hallucinations in that disease.

Abstract
Lithium is considered to be the first choice mood stabilizer in recurrent mood disorders. Its widespread and large-scale use is the result of its proven efficacy. In spite of this fact, patients have been observed to show a variable response to lithium treatment: in some cases it is completely effective in preventing manic or depressive relapses, while in other cases it appears to show no influence on the disease course. The possible definition of a genetic liability profile for adverse effects and efficacy will be of great help, as lithium therapy needs at least 6 months to be effective in stabilizing mood disorders. During the last few years, a number of groups have reported possible liability genes. Lithium long-term prophylactic efficacy has been associated with serotonin transporter protein, tryptophan hydroxylase and inositol polyphosphate 1-phosphatase variants. A number of other candidate genes and anonymous markers did not yield positive associations. Therefore, even if some positive results have been reported, no unequivocal susceptibility gene for lithium efficacy has been identified. Although the available data may not currently allow a meaningful prediction of lithium response, future research is aimed at the development of individualized treament of mood disorders, including the possibility of 'pharmacological genetic counseling'.

Abstract
Although psychosis is common in bipolar disorder, few studies have examined the prognostic significance of psychotic features. In addition, some studies suggest that the presence of mood-incongruent psychosis, in particular, is associated with poorer outcome compared with mood-congruent psychosis. We assesses the phenomenology and prevalence of mood-congruent and mood-incongruent psychotic symptoms in 352 patients with bipolar I disorder participating in the Stanley Foundation Bipolar Treatment Network. We compared the demographic and clinical features, and measures of psychosocial and vocational functioning in patients with and without a history of psychosis. The phenomenology of psychosis in this cohort of patients with bipolar disorder was similar to that reported in earlier studies and supported the lack of diagnostic specificity of any one type of psychotic symptom. There were no significant differences between patients with and without a history of psychosis on any demographic, psychosocial, vocational, or course of illness variables. Only family history of bipolar disorder was significantly more common in patients with nonpsychotic bipolar disorder compared to patients with a history of psychosis. Among bipolar patients with a history of psychosis, only the proportion of women and lifetime prevalence rates of anxiety disorders occurred significantly more in patients with mood-incongruent delusions. In this large cohort of outpatients with bipolar I disorder, neither a history of psychosis nor of mood-incongruent psychosis had prognostic significance at entry into the Network. The lack of observable prognostic impact may have been, in part, due to the relatively high morbidity and poor functional outcome of a substantial portion of the total cohort.

Abstract
BACKGROUND The purpose of this study was to determine the prevalence of substance use disorders (substance abuse or substance dependence: SA/SD) in a large sample of Bipolar Type I (BPI) patients drawn from the Costa Rican population and to describe the effects of SA/SD on the course of their bipolar disorder. METHOD 110 subjects from two high-risk (for BPI) Costa Rican pedigrees and 205 unrelated Costa Rican BPI subjects were assessed using structured interviews and a best estimate process. Chi(2) and survival analyses were performed to assess the effect of gender on comorbidity risk, and the effect of comorbidity on the clinical course of BPI. RESULTS SA/SD (primarily alcohol dependence) occurred in 17% of the BPI patients from the population sample and 35% of the BPI patients from the pedigree sample. Comorbid SA/SD was strongly associated with gender chi(2) = 16.84, P = 0.00004). In comorbid subjects, alcohol dependence tended to predate the first manic episode (chi(2) = 6.54, P < 0.025). History of SA/SD did not significantly alter the prevalence of psychosis or age of onset of mania in BPI subjects. CONCLUSIONS These results suggest that SA/SD comorbidity rates are lower in this type of population than in BPI patient populations in the US. Gender is a strong predictor of comorbidity prevalence in BPI patients from this population. Although SA/SD may be a risk factor for precipitating BPI in those at risk, in this population comorbid BPI subjects do not have a different onset or course of BPI in comparison to BPI patients without comorbidity.

Abstract
Lithium is the most widely used long-term treatment for recurrent mood disorders. Despite its proven efficacy, patients show a variable response, ranging from complete efficacy to no influence at all. This paper reviews possible predictors of response focusing on molecular genetic studies. The functional polymorphism in the upstream regulatory region of the serotonin transporter gene (5-HTTLPR) has been associated with lithium long-term efficacy in two independent studies, marginal associations have been reported for tryptophan hydroxylase and inositol polyphosphate 1-phosphatase (INPP1). A number of other candidate genes and anonymous markers did not yield positive associations. Therefore, even though some positive results have been reported, no unequivocal susceptibility gene for lithium efficacy has been identified.

Abstract
Psychotic symptoms are common in both the manic and depressive phases of bipolar disorder. More than half of patients with bipolar disorder will experience psychotic symptoms in their lifetime. Grandiose delusions are the most common type of psychotic symptom, but any kind of psychotic symptom, including thought disorder, hallucinations, mood-incongruent psychotic symptoms, and catatonia can present as part of a manic episode. Psychotic symptoms suggest poor prognosis when they occur in the absence of affective symptoms. However, psychotic symptoms can mask affective symptoms and make the distinction between manic-depressive illness and other psychiatric disorders difficult, especially in minorities. Careful assessment of prior psychiatric history, family history, and treatment response can aid in the differentiation of affective disorders with psychotic features from psychotic disorders.

Abstract
Clinical predictors of the efficacy of lithium prophylaxis in mood disorders have great potential value. Melancholic features during depressive phases have been both proposed and rejected as valid predictors of favorable outcome. The aim of the present study is to describe the validity of melancholic features during depressive phases as predictors of the prophylactic efficacy of lithium. Sixty-one subjects affected by bipolar (n = 51) and major depressive (n = 10) disorder were followed prospectively for an average of 53 months. All subjects were evaluated as a lifetime perspective at intake, by the Operational Criteria checklist for psychotic illness (OPCRIT). Melancholic features were correlated with outcome only when controlling for time of first lithium administration. These two variables accounted for more than 30% of the total variance in lithium response. Others clinical factors such as polarity, delusions, gender, onset, personality disorders, and family history of mood disorders did not influence the observed association. Our preliminary findings suggest that melancholic features may be associated with favorable lithium prophylactic outcome in mood disorders.

Abstract
We studied a group of 23 manic patients to ascertain the prognostic significance of mixed affective features. Eight patients (34.8%) presented with a mixed manic state. This mixed state correlated with a longer hospitalization and significantly worse disposition outcome. In the light of previous conceptual models the authors speculate about the meaning of DSM-III defined mixed bipolar disorder.

Abstract
Four hundred thirty-eight bipolar manics were admitted to an acute care psychiatric inpatient ward over a 12-year period. Eighty percent had good and 20% poor immediate outcome. Good outcome patients were characterized by short episode duration, older age of onset, a longer hospitalization, fewer suicide thoughts, and less psychiatric and medical comorbidity than the poor outcome group. Patients were divided into four treatment groups based on primary mode of therapy during index hospitalization: electroconvulsive therapy (ECT), adequate lithium, inadequate lithium, and neither treatment. Patients experiencing good outcome were more likely to be in the adequate lithium group and less likely to receive neither treatment. Regression analysis identified the absence of comorbidity, duration of lithium treatment more than 2 weeks, and duration of episode of less than 1 month as predictors of good outcome at hospital discharge.

Abstract
There have been several advances in the knowledge of the phenomenology of Bipolar Manic-Depressive Illness in the past decade. Studies of groups of carefully diagnosed bipolar patients have characterized features of the course of illness, the presence and prognostic influence of psychotic features, the influence of stressful life events, features of social adjustment and aspects of personality and long-term functioning. Similar studies of bipolar illness in non-western cultures would be of interest.
