Effects of cognitive psychotherapy on the biological rhythm of patients with depression

Effectiveness of Chinese herbal medicine granules and traditional Chinese medicine-based psychotherapy for perimenopausal depression in Chinese women: a randomized controlled trial

OBJECTIVE

The aim of the study was to assess the effectiveness of Chinese herbal medicine combined with traditional Chinese medicine (TCM)-based psychotherapy (TBP) on perimenopausal depression (PMD).

METHODS

This multicenter, randomized, placebo-controlled clinical trial was conducted in nine hospitals in China between August 2015 and June 2017. The study included 307 women with PMD who were divided randomly into two treatment groups: the Bushen Tiaogan formula (BSTG) plus TBP (n = 156) and placebo plus TBP (n = 151). All participants underwent treatment for 8 weeks and were followed up for 4 weeks. The primary outcome measures included scores of the Greene Climacteric Scale (GCS), Self-Rating Depression Scale (SDS), and Self-Rating Anxiety Scale (SAS). Secondary outcomes included serum levels of sex hormones and lipids, as well as adverse events.

RESULTS

The average GCS, SDS, and SAS scores after treatment were significantly lower in the BSTG-plus-TBP group than those in the placebo-plus-TBP group, and the differences were greatest at the end of the 12th week: the average GCS scores were 10.8 in the BSTG-plus-TBP group versus 18.5 in the placebo-plus-TBP group (P < 0.001); the average SDS scores were 30.7 in the BSTG-plus-TBP group versus 45.4 in the placebo-plus-TBP group (P < 0.001); the SAS scores were 28.6 in the BSTG-plus-TBP group versus 42.6 in the placebo-plus-TBP group (P < 0.001). In addition, treatments with BSTG plus TBP significantly reduced the levels of basal follicle-stimulating hormone (P = 0.045) and triglycerides (P = 0.039) and increased the level of high-density lipoprotein cholesterol (P < 0.001) compared to placebo treatments with TBP. No serious adverse events occurred, and the safety indices of complete blood counts, renal function, and liver function were within normal ranges, before and after treatments.

CONCLUSIONS

Treatment with BSTG formula plus TBP was more effective than TBP alone for improving PMD symptoms, sexual hormone levels, and blood lipid conditions in women with mild PMD.

Circadian insights into the biology of depression: Symptoms, treatments and animal models

In depression, symptoms range from loss of motivation and energy to suicidal thoughts. Moreover, in depression alterations might be also observed in the sleep-wake cycle and in the daily rhythms of hormonal (e.g., cortisol, melatonin) secretion. Both, the sleep-wake cycle and hormonal rhythms, are regulated by the internal biological clock within the hypothalamic suprachiasmatic nucleus (SCN). Therefore, a dysregulation of the internal mechanism of the SCN might lead in the disturbance of temporal physiology and depression. Hence, circadian symptoms in mood disorders can be used as important biomarkers for the prevention and treatment of depression. Disruptions of daily rhythms in physiology and behavior are also observed in animal models of depression, giving thus an important tool of research for the understanding of the circadian mechanisms implicated in mood disorders. This review discusses the alterations of daily rhythms in depression, and how circadian perturbations might lead in mood changes and depressive-like behavior in humans and rodents respectively. The use of animal models with circadian disturbances and depressive-like behaviors will help to understand the central timing mechanisms underlying depression, and how treating the biological clock(s) it may be possible to improve mood.

Construction of a biological rhythm assessment scale for children

Abstract Introduction Biological rhythm is associated with the level of alertness, cognitive performance and mood of the individuals. Its regularity is essential to preserve good health and quality of life. Objective To present the steps for the construction of the scale entitled Biological Rhythm Interview of Assessment in Neuropsychiatry – Kids (BRIAN-K), designed to measure biological rhythm disruptions in Brazilian children and adolescents. Methods Items were developed following the adult version of the scale. Analysis of the psychometric characteristics of the scale was based on the responses of 373 parents/caregivers of school age children (7 and 8 years old). Results A theoretical model of 17 items with the purpose of evaluating four domains (sleep, activities, social rhythm and eating pattern) was determined using exploratory factor analysis (EFA) and via identification of a general factor. The psychometric properties of the BRIAN-K showed favorable properties. Conclusion Only two items needed to be rewritten. Further studies are needed to investigate the instrument's adequacy to different age groups and additional evidence of validity and reliability.

Long-term effects of cognitive therapy on biological rhythms and depressive symptoms: A randomized clinical trial

OBJECTIVE

To evaluate the effect of cognitive therapy on biological rhythm and depressive and anxious symptoms in a twelve-month follow-up period. In addition, correlations between the reduction of depression and anxiety symptoms and the regulation of biological rhythm were observed.

METHODS

This was a randomized clinical trial with young adults from 18 to 29 years of age who were diagnosed with depression. Two models of psychotherapy were used: Cognitive Behavioral Therapy (CBT) and Narrative Cognitive Therapy (NCT). Biological rhythm was assessed with the Biological Rhythm Interview of Assessment in Neuropsychiatry (BRIAN). Severity of depressive and anxious symptoms was assessed by the Hamilton Depression Rating Scale (HDRS) and the Hamilton Anxiety Rating Scale (HARS), respectively. The sample included 97 patients who were divided within the protocols of psychotherapy.

RESULTS

There was a significant reduction in depressive and anxious symptoms (p<0.001) and an increase on regulation of biological rhythm (p<0.05) at the twelve-month follow-up. Moreover, we showed a positive correlation between the reduction of depressive symptoms and regulation of biological rhythm (r=0.638; p<0.001) and between the reduction of anxious symptoms and regulation of biological rhythm (r=0.438; p<0.001).

CONCLUSION

Both models showed that cognitive therapy was effective on the reduction of depressive and anxious symptoms and on the regulation of biological rhythm at a twelve-month follow-up evaluation. This study highlights the association between biological rhythm and symptoms of depression and anxiety.

LIMITATION

We did not assess genetic, hormonal or neurochemical factors and we did not include patients under pharmaceutical treatment or those with severe symptomatology.

Cognitive psychotherapy treatment decreases peripheral oxidative stress parameters associated with major depression disorder

INTRODUCTION

Studies have already pointed out the contribution of oxidative stress in the pathophysiology of major depressive disorder (MDD). The aim of the present study was to investigate the oxidative-antioxidative systems in MDD and in response to cognitive psychotherapies. Oxidative stress were analyzed in 49 MDD patients at baseline, post-treatment, and follow-up; and 49 control subjects without history of psychiatric disorders.

RESULTS

MDD subjects presented an increase in oxidative damage related to control subjects for thiobarbituric acid reactive species (TBARS), nitric oxide, and a decrease in total thiol content. Cognitive psychotherapies were able to counteract peripheral oxidative stress in MDD patients, reducing TBARS levels (p<0.001) in the follow-up, nitric oxide (p<0.001) in the post-treatment and follow-up, and increasing the total thiol content (p<0.01) in the post-treatment and follow-up.

CONCLUSION

Oxidative stress was associated with MDD and the regulation of these parameters might represent an important mechanism associated with the clinical improvement of cognitive psychotherapy.

Analysing Biological Rhythms in Fibromyalgia Syndrome

AIM

This study evaluated biological rhythm disorders in patients with fibromyalgia syndrome (FMS).

METHODS

The study enrolled 82 patients with FMS and 82 controls. Pain intensity was evaluated using a visual analogue scale (VAS). The psychological conditions of the patients were evaluated using the Beck Depression Inventory (BDI). The Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) was used to assess disturbances in biological rhythms (ie sleep, activity, social and eating patterns).

RESULTS

There was no difference between the two groups at baseline (all p > 0.05). The BDI, BRIAN total, sleep, activity, social, and eating scores were higher in patients with FMS than in the controls (all p < 0.001). Further, a significant correlation was found between biological rhythms and BDI scores (p < 0.001) and there were positive correlations between the VAS score and BRIAN total, sleep, and eating and BDI in patients with FMS (all p < 0.001).

CONCLUSION

There are marked biological rhythm disturbances in FMS. There is an important relationship between rhythm disorders and FMS. The disturbances in sleep, functional activities, social participation, and disordered rhythms like eating patterns show the need for a multidisciplinary approach to treating patients with FMS.

Neurotrophic factors, clinical features and gender differences in depression

Recent studies have evaluated the role of brain-derived neurotrophic factor (BDNF) in mood disorders; however, little is known about alterations in nerve growth factor (NGF) and glial cell line-derived neurotrophic factor (GDNF). The aim of this study was to evaluate differences among serum neurotrophic factors (BDNF, NGF and GDNF) in depressed patients and healthy controls and to verify the association between serum neurotrophic levels and clinical characteristics in a young, depressed population stratified by gender. This is a cross-sectional study with depressed patients and population controls 18-29 years of age. The concentrations of neurotrophic factors were determined by the ELISA method. The diagnosis of depression and the duration of the disease were assessed by the Structured Clinical Interview according to the diagnostic and statistical manual of mental disorders. Depression severity was measured with the 17-item Hamilton Rating Scale for Depression, and the severity of anxiety symptoms was measured using the Hamilton Anxiety Rating Scale. Serum BDNF and GDNF were lower in major depressive disorder (MDD) patients compared to controls (p ≤ 0.001). Serum NGF levels were higher in MDD patients versus controls (p ≤ 0.001). BDNF was associated with the duration of disease only in women (p = 0.005). GDNF was not associated with clinical characteristics in either gender. In women, NGF was associated with the severity of depressive symptoms (p = 0.009), anxiety (p = 0.011) and disease duration (p = 0.005). NGF was associated with disease duration in men (p = 0.026). Our results demonstrated that significant neurochemical differences in NGF and BDNF, but not in GDNF, were associated with the clinical features of MDD when patients were stratified by gender.
