Correlates of 1-year prospective outcome in bipolar disorder: results from the Stanley Foundation Bipolar Network.
ABSTRACT The purpose of the study was to examine potential correlates of outcome in patients treated for bipolar disorder.
During a 1-year period, 258 patients with DSM-IV bipolar disorder or schizoaffective disorder were rated with the prospective NIMH-Life Chart Method, which characterizes each day in terms of the severity of manic and depressive symptoms on the basis of patients' mood-related impairment in their usual educational, social, or occupational roles. Mean ratings for the severity of mania, depression, and overall bipolar illness and the number of manic, depressive, and overall illness episodes were calculated. Potential risk factors were assessed at the start of the study, and multivariate linear regression analysis was used to determine the correlates of the six 1-year outcome measures.
Three of the six outcome measures were largely independent of each other and were used in the analysis. The mean rating for severity of mania was associated with comorbid substance abuse, history of more than 10 prior manic episodes, and poor occupational functioning at study entry. The mean rating for severity of depression was associated with a history of more than 10 prior depressive episodes and poor occupational functioning at study entry. The total number of overall illness episodes was associated with a positive family history of drug abuse, a history of prior rapid cycling, and poor occupational functioning. In addition, the mean rating for severity of mania and the total number of overall illness episodes were both initially associated with a history of childhood abuse, but these relationships were lost with the addition of other illness variables to the analysis.
Clinicians who treat patients with bipolar disorder should consider a family history of drug abuse, a history of childhood abuse, prior course of illness, comorbid substance abuse, and occupational functioning in determining prognosis and setting goals for further treatment.

ABSTRACT: Assessment of studies related with bipolar disorder in Turkey did not reveal an epidemiologically qualified field study. Most of the studies are hospital based or clinical studies which did not include a systematical scanning and did not aim to collect any epidemiological data and transfer information to health authorities. The generalizability of these studies to our community is far from being valid and reliable. On the other hand, a profile which will be created by reviewing the findings of these studies performed in various regions of Turkey will have a contribution to knowing the “unique to us” features of bipolar disorder and determining cultural risk factors. All this information can constitute a basis for formation and development of public mental health services related with bipolar disorder. In Turkey, the need for epidemiologically significant, polycentric, public sampled studies with broad participation is indispensable. Although our psychiatric epidemiology and clinical studies include necessary scientific basis, they are not powerful enough to evaluate the authentic and progressional relations such as rapid urbanization and immigration. The aim of this review is to evaluate and discuss prominent epidemiological findings, deficiencies and possibile future activities related with studies conducted in Turkey about bipolar disorderPsikiyatride Guncel Yaklasimlar 06/2014; 6(2):199-209.

ABSTRACT: OBJECTIVE The authors sought to identify and evaluate longitudinal mood trajectories and associated baseline predictors in youths with bipolar disorder. METHOD A total of 367 outpatient youths (mean age, 12.6 years) with bipolar disorder with at least 4 years of follow-up were included. After intake, participants were interviewed on average 10 times (SD=3.2) over a mean of 93 months (SD=8.3). Youths and parents were interviewed for psychopathology, functioning, treatment, and familial psychopathology and functioning. RESULTS Latent class growth analysis showed four different longitudinal mood trajectories: "predominantly euthymic" (24.0%), "moderately euthymic" (34.6%), "ill with improving course" (19.1%), and "predominantly ill" (22.3%). Within each class, youths were euthymic on average 84.4%, 47.3%, 42.8%, and 11.5% of the follow-up time, respectively. Multivariate analyses showed that better course was associated with higher age at onset of mood symptoms, less lifetime family history of bipolar disorder and substance abuse, and less history at baseline of severe depression, manic symptoms, suicidality, subsyndromal mood episodes, and sexual abuse. Most of these factors were more noticeable in the "predominantly euthymic" class. The effects of age at onset were attenuated in youths with lower socioeconomic status, and the effects of depression severity were absent in those with the highest socioeconomic status. CONCLUSIONS A substantial proportion of youths with bipolar disorder, especially those with adolescent onset and the above-noted factors, appear to be euthymic over extended periods. Nonetheless, continued syndromal and subsyndromal mood symptoms in all four classes underscore the need to optimize treatment.American Journal of Psychiatry 05/2014; 171(9).

ABSTRACT: The severity of bipolar disorder can be assessed using the daily prospective National Institute of Mental Health׳s Life Chart Method (LCM-p). Also for scientific research the LCM-p, has been used frequently. However, processing and analyzing the LCM-p for research purposes, are challenging because of the multitude of complex measures that can be derived from the data. In the current paper we review the different LCM-p course variables (mood episodes, average severity, proportion of time ill and mood switches) and their definitions. Strengths and limitations and the impact of the use of different LCM-p course measures and definitions on the research results are described. A systematic review of original papers on the LCM was conducted using 9 electronic databases for literature between January 1996 and December 2014. Papers using other prospective charting procedures were not evaluated in the current study. The initial literature search led to 1352 papers of which 21 were eventually selected. A relatively wide variety of definitions of LCM-p course variables was used across the studies. Especially for the calculation of number of episodes and mood switch no univocal definition seems to exist. Across studies several different durations and severity criteria are applied to calculate these variables. We describe which variables and definitions are most suitable for detecting specific bipolar disease course characteristics and patterns. In the absence of a golden standard for the calculation of LCM-p course variables, researchers should report the exact method they applied to their LCM-p data, and clearly motivate why this is their method of first choice considering their research aim.
