There is conflicting evidence regarding the educational level and its importance for social and occupational functioning in bipolar disorder (BD). The aim of this study was to investigate how educational achievement relates to function in BD compared with the general population, and which clinical factors are associated with level of education.
Hospitalized patients with DSM-IV BD (N=257; 69.3% BD I; 25.7% BD II; 5.1 BD NOS; 51.4% females) were consecutively recruited from mental health clinics throughout Norway and compared with a geographically matched reference sample from the general population (N=56,540) on levels of education, marital status, income, and disability benefits. Further analyses of association were carried out using logistic regression analyses.
A significantly higher proportion of subjects in the BD group than in the reference group was single, had low income, or was disabled. No between-group difference was found in educational level. In the reference group education was inversely correlated with the risk of being disabled, but no such relationship was found in the BD group. Rapid cycling and recurring depressive episodes were the only clinical characteristics associated with low educational level.
Acutely admitted patients might not be representative for milder forms of disease.
Despite similar levels of education, BD patients had lower social and occupational function than the general population, and no association was found between education and disability for BD patients.
"Finally, many demographic variables were unavailable in the database, such as socioeconomic status, lifestyle, and family medical history; analysis of these variables may have provided useful information regarding additional factors associated with GERD and bipolar disorder. –. "
[Show abstract][Hide abstract] ABSTRACT: BackgroundStudies have shown that chronic inflammation may play a vital role in the pathophysiology of both gastroesophageal reflux disease (GERD) and bipolar disorder. Among patients with GERD, the risk of bipolar disorder has not been well characterized.ObjectiveWe explored the relationship between GERD and the subsequent development of bipolar disorder, and examined the risk factors for bipolar disorder in patients with GERD.MethodsWe identified patients who were diagnosed with GERD in the Taiwan National Health Insurance Research Database. A comparison cohort without GERD was matched according to age, sex, and comorbidities. The occurrence of bipolar disorder was evaluated in both cohorts based on diagnosis and the prescription of medications.ResultsThe GERD cohort consisted of 21,674 patients, and the comparison cohort consisted of 21,674 matched control patients without GERD. The incidence of bipolar disorder (incidence rate ratio [IRR] 2.29, 95% confidence interval [CI] 1.58–3.36, P<.001) was higher among GERD patients than among comparison cohort. Multivariate, matched regression models showed that the female sex (hazard ratio [HR] 1.78, 95% CI 1.76–2.74, P = .008), being younger than 60 years old (HR 2.35, 95% CI 1.33–4.16, P = .003), and alcohol use disorder (HR 4.89, 95% CI 3.06–7.84, P = .004) were independent risk factors for the development of bipolar disorder among GERD patients.ConclusionsGERD may increase the risk of developing bipolar disorder. Based on our data, we suggest that attention should be focused on female patients younger than 60 years, and patients with alcohol use disorder, following a GERD diagnosis.

"Specifically, earlier studies included patients with the classical diagnosis of manic-depressive illness whereas recent studies investigated patients diagnosed using a broader approach, reflecting the concept of bipolar spectrum. Early findings consistently showed an association between high SES and the diagnosis of BD (Malzberg 1956; Verdoux and Bourgeois 1995), whereas newer studies have failed to find any relationship at all (Schoeyen et al. 2011) and in some cases an opposite one (Tsuchiya et al. 2004). There have been speculations that these differences are due to methodological problems such as treatment bias, lack of appropriate reference samples, and failure to control for demographic variables (2011; Coryell et al. 1989).

[Show abstract][Hide abstract] ABSTRACT: Background
In psychiatric literature stretching over a century, there have been glaring discrepancies in the findings describing the relationship between bipolar disorder (BD) and socioeconomic status (SES). Early studies indicated an overall association between manic-depressive illness and higher social class. However, recent epidemiologic studies have failed to find an association between BD and SES. Instead, they report a similar distribution of BD among social classes and educational levels, and in one particular study, a lower family income was reported. The determinants of SES are complex, and the early findings are now interpreted as having been incorrect and stemming from past methodological weaknesses.
For this analysis we explored the relationship between SES and BD in a sample of patients who had participated in prior clinical and therapeutic studies. These patients met the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for BD, required long-term stabilizing treatment, and were assessed in terms of their response to lithium stabilization and a number of other clinical characteristics in accordance with research protocol. Good response to lithium stabilization (LiR) served as a proxy for identifying a subtype of manic-depressive illness, the classical form of BD. Non-responders to stabilizing lithium (LiNR) were considered belonging to other subtypes of bipolar spectrum disorder. The SES of the parents was measured upon entry into treatment using the Hollingshead SES scale, which despite its limitations has been used in psychiatry most widely to determine SES. The groups of LiR and LiNR were compared statistically in terms of SES. The influence of bipolar subtype and gender on SES was investigated.
Results and discussion
A significantly higher SES was associated with the lithium-responsive form (LiR) of BD when compared with patients continuing to relapse despite adequate lithium treatment (representing other types of bipolar spectrum). Our observation suggests that the discrepant literature findings about SES and BD may be better explained by the change in diagnostic practices: early studies describing a positive relationship included mostly classical manic-depressive disorder, while the patients in recent studies have been diagnosed according to much broader criteria, reflecting the era of bipolar spectrum disorder.
[Show abstract][Hide abstract] ABSTRACT: A model that assumes tonal decomposition of textures is proposed
for texture segmentation. The model assumes that the tones form an
orthogonal basis in a vector space of possible textures. Two methods for
texture segmentation that use a texture indicator developed from this
concept are demonstrated
