Impact of biological rhythms on perception of illness and cognitive flexibility in bipolar patients in remission.

Our study aims to examine the possible mediating effects of biological rhythms on the relationship between illness perception, cognitive flexibility, and functionality in bipolar patients in remission. A total of 150 patients with bipolar disorder (BD) were enrolled. The sociodemographic data form, Biological Rhythm Interview of Assessment in Neuropsychiatry (BRIAN), Brief Illness Perception Questionnaire (BIPQ), Cognitive Flexibility Scale (CFS), Young Mania Rating Scale, Montgomery and Asberg Depression Scale, Beck Anxiety Inventory, and Short Functionality Assessment Scale were applied to the patients in the study. The mean age of the patients was 42.10 ± 12.92 (SD). The participants were 48.7% (n = 73) female and 66.6% (n = 100) BD-I. There was a negative correlation between the total BRIAN score and favorable BIPQ scores and a positive correlation between the total BRIAN score and unfavorable BIPQ scores (except timeline). Additionally, multiple regression analyses revealed that the total BRIAN score could predict favorable BIPQ (except treatment control) and unfavorable BIPQ (except timeline) scores (p < 0.05). The total CFS score also could predict favorable BIPQ (treatment control) and unfavorable BIPQ scores (except timeline). The second step mediation analysis showed that biological rhythm mediated the relationship between illness perception and cognitive flexibility. Our study found that biological rhythms played a full mediating role in the relationship between the perception of illness and cognitive flexibility. In addition, worsening in biological rhythms in bipolar patients could cause negative beliefs and attitudes towards their diseases with an unfavorable clinical course. Therefore, regularity in biological rhythms should be highly recommended for bipolar patients.

Peripheric and central olfactory measurements in patients with bipolar disorder.

BACKGROUND: Bipolar disorder (BD) is a mental health disorder. PURPOSE: To investigate the peripheric and central olfactory measurements in patients with BD using magnetic resonance imaging (MRI). MATERIAL AND METHODS: This study was conducted retrospectively. Group 1 consisted of 27 euthymic patients with BD (14 men, 13 women) and Group 2 consisted of 27 healthy controls (14 men, 13 women). Olfactory bulb (OB) volume and olfactory sulcus (OS) depth (peripheric), and corpus amygdala and insular gyrus area (central) measurements were performed using cranial MRI. RESULTS: OB volume and OS depth value of the bipolar group were lower than the control group, but there were no significant differences between the groups (P > 0.05). The corpus amygdala and left insular gyrus area of the bipolar group were significantly lower than those in the control group (P < 0.05). There were positive correlations between OB volumes and OS depths, the insular gyrus areas, and the corpus amygdala areas (P < 0.05). As the number of depressive episodes and duration of illness increased in bipolar patients, the depth of the sulcus decreased (P < 0.05). CONCLUSION: In the present study a correlation was detected between OB volumes and the structures, known as emotional processing (e.g. insular gyrus area, corpus amygdala), and clinical features. Accordingly, new treatment techniques, such as olfactory training, may be considered an option in the treatment of such patients with BD.

Emotion dysregulation in migraine patients: can it be a hallmark the probability of the transformation from episodIc to chronic?

OBJECTIVE: The main aim of this study was to examine patients with migraine in terms of emotional dysregulation and to evaluate whether the emotion dysregulation is effective on chronicity in migraine. MATERIALS AND METHODS: A total of 85 migraine patients and 61 healthy participants were included in this study. All participants were evaluated using Migraine Disability Scale (MIDAS), Visual Analog Scale (VAS), Depression, Anxiety, and Stress Scale (DASS-21), Difficulties in Emotion Regulation Scale (DERS), Pain Catastrophizing Scale (PCS), and the Discomfort Intolerance Scale (DIS). Then, all results were compared between the migraine patients and healthy individuals. In addition, the migraine patients were separated into three groups as patients without an aura, patients with an aura and patients with chronic migraine and then their results were compared among them. Finally, the predictive markers of chronic migraine were explored using regression analyses. RESULTS: Among 85 migraine patients, the mean age was 31.5 (SD = 7.98); 83.5% were women. The total and subscale scores of DERS, PCS, DIS, and DASS-21 were significantly higher in patients than in healthy individuals (p < 0.01). Subscale scores of DERS, DIS, and DASS-21 in the chronic migraine patients were found to be higher than in the other two patient groups (p < 0.01). Logistic regression analysis showed that chronic migraine could be associated with 'lack of emotional clarity' (OR = 1.229; p = 0.042), 'lack of awareness' (OR = 1.187; p = 0.032), 'migraine associated disability' (OR = 1.128; p = 0.033), and 'stress' (OR = 1.292; p = 0.027). CONCLUSION: This study results showed that chronic migraine could be associated with the emotional dysregulation. To our knowledge, this study is the preliminary study in the literature and, therefore, new studies with large samples are needed.

Evaluation of emotional dysregulation in patients with restless legs syndrome.

The aim of this study is to examine patients with restless legs syndrome (RLS) in terms of difficulty in emotion regulation and insomnia. A total of 52 patients with RLS and 57 healthy volunteers were enrolled. Difficulties in Emotion Regulation Scale Short Form (DERS-16), Insomnia Severity Index (ISI), Hospital Anxiety and Depression Scale (HADS), and International Restless Legs Syndrome rating scale were applied to participants. The mean age was 34.00 ± 8.27 years in patients and 31.70 ± 9.12 years in control. The scores of DERS-16, ISI, HADS-A, and HADS-D were significantly higher in the patients than the controls (p = 0.000). The DERS-16 total score showed a significant correlation with age (r = 0.404, p = 0.003), ISI (r = 0.281, p = 0.043), IRLS score (r = 0.422, p = 0.002), HADS-A (r = 0.409, p = 0.003), and HADS-D (r = 0.416, p = 0.002). The factors (age, gender, ferritin, ISI, and IRLS scores) that may be associated with the DERS-16 total scores were assessed with stepwise regression analysis. It was seen that the IRLSs variable had the most ability and could predict 45% (ß = 0.625, p < 0.001, ∆R2 = 0.450) of difficulty in emotion regulation. In addition, the variable of insomnia could predict difficulty in emotion regulation by 17% (ß = 0.097, p = 0.001, ∆R2 = 0.170). Patients with RLS may experience more emotion regulation difficulties than healthy controls. RLS severity and insomnia may be factors affecting emotion regulation difficulties in patients with RLS. According to our knowledge and our literature review, this finding seems to be the first report in the literature.

Impact of metabolic syndrome and clinical features on functioning in patients with bipolar disorder: a cross-sectional study

Objective: The metabolic syndrome (MS) is highly prevalent among patients with bipolar disorder (BD), and may affect progression, functioning, and comorbid conditions in BD. The aim of this study was to investigate the effect of clinical variables and MS on overall functioning and specific areas of functioning in patients with BD. Methods: A total of 210 participants (140 participants with BD I and BD II in remission and 70 non-psychiatric control subjects) were included. The investigators administered the Young Mania Rating Scale (YMRS), the Bipolar Depression Rating Scale (BDRS), the Global Assessment of Functioning Scale (GAF), and the Bipolar Disorder Functioning Scale (BDFS). The participants completed the Beck Depression Scale (BDS) and the Beck Anxiety Scale (BAS). MS was diagnosed according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria. Hierarchical regression analysis was used to investigate potential correlations of comorbid MS with clinical variables and level of functioning. Results: Level of functioning did not differ between patients with and without MS. However, there were significant correlations between the level of functioning subscales and the number of depressive episodes (p = 0.033), level of general functioning (p = 0.012), duration of illness (p = 0.012), BDS (p = 0.005), BDRS (p = 0.021), BAS total scores (p = 0.021), number of hypomanic episodes (p = 0.022), number of hospitalizations (p = 0.003), employment status (p = 0.032), and diagnosis of BD I (p = 0.007) and BD II (p = 0.044). Conclusion: Our findings suggest that clinical variables had a greater effect on functioning than MS in BD patients.

Metabolic syndrome in bipolar disorder: prevalence, demographics and clinical correlates in individuals with bipolar I, bipolar II, and healthy controls

Abstract Background: The metabolic syndrome is a growing global public health problem and highly prevalent in patiens with bipolar disorder. There are a few studies about relationship between metabolic syndrome and bipolar disorder subtypes. Objective: The aim of this study was to investigate the prevalence of metabolic syndrome (MS) and its individual components in subjects with bipolar I (BD I) and bipolar II (BD II) disorder compared with non-psychiatric controls, and to determine the variables affecting MS. Methods: A total of 210 individuals (mean age 42.5 ± 11.87, 58.1% female) of whom 70 had BD I, 70 BD II, and 70 controls, were included in this study. MS was diagnosed according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III), the adapted ATP III (ATP III-A) and the International Diabetes Federation (IDF) criteria. Results: Participants with BD I had a significantly higher prevalence of MS when compared to individuals BD II and non-psychiatric controls according to the NCEP-ATP III, ATP III-A, and IDF criteria (ps < 0.01). In individuals with MS, increased waist circumference was the most common abnormality. Logistic regression analysis revealed that the presence of physical illness, age and number of cigarettes smoked significantly predicted the presence of MS. Discussion: This study showed that MS was more prevalent among BD I individuals compared to BD II and controls, and highlighted the importance of regular screening for MS in individuals with BD.
