RESUMO

OBJECTIVES: To evaluate the effectiveness of repetitive transcranial magnetic stimulation (rTMS) started with citalopram in first-episode young major depressive patients. METHODS: In a 2-week double-blind study with a 2-week extended antidepressant phase, 60 first-episode young major depressive patients were randomly assigned to citalopram in combination with 2 weeks of either active or sham rTMS treatment. During the following 2 weeks, the patients continued only the citalopram treatment. The 17-item Hamilton depression rating scale (HAMD-17) and Montgomery-Asberg depression rating scale (MADRS) were used to assess the severity of depression. Moreover, the Wisconsin Card Sorting Test (WCST), Trail-Making Test (TMT), and Stroop Color-Word Test (SCWT) were used to assess executive function. RESULTS: (1) There was a significantly greater number of early improvers (a reduction of HAMD-17 score ≥ 20% within the first 2 weeks) observed in the active rTMS group compared to the sham group (57% vs. 29%, χ(2)=4.667, p=0.031). (2) There was no significant difference observed in responder rates (46% vs. 36%, χ(2)=0.295, p=0.586) or in remission rates (39% vs. 29%, χ(2)=0.319, p=0.572) between the two groups at 4 weeks. (3) There was a significant difference seen in both HAMD-17 and MADRS scores between the two groups at 2 and 4 weeks. The active rTMS group showed a significantly faster score reduction compared to the sham group at 2 weeks (HAMD-17, t=13.444, p=0.001; MADRS, t=30.123, p=0.000), which was maintained at 4 weeks on both scales (HAMD-17, t=46.915, p=0.000; MADRS, t=39.996, p=0.000). (4) The patients did not deteriorate in executive performance, and even improved in categories on WCST and completed TMT faster in the active group. CONCLUSIONS: RTMS accelerated the rapidity of the antidepressant response in first-episode young depressive patients. Our results call for future rTMS studies with larger sample sizes, high intensity of stimuli, and longer duration to draw more definitive conclusions.

RESUMO

OBJECTIVE: To assess the early therapeutic and cognitive effect of repetitive transcranial magnetic stimulation (rTMS) combined with antidepressant medication in treatment of first-episode patients with major depression. METHODS: Sixty first-episode depressed inpatients aged 18-45 y, who met the DSM-IV clinical criteria for major depressive episode were randomly assigned to citalopram treatment (20 mg/d) in combination with a two-week period of either rTMS (study group)or sham procedure (control group) on left dorsal-lateral prefrontal cortex (10 Hz, 90% motor threshold). The Hamilton Depression Rating Scale (HAMD) was used to assess the severity of depression. The Wisconsin Card Sorting Test (WCST) and Continuous Performance Test (CPT) were used to assess cognitive function of depression. RESULT: The response rate was significantly greater in the study group compared to the control group after treatment (57% compared with 29%,P<0.05). The HAMD scores significantly declined after treatment in two groups, and the study group showed lower scores compared to the control group after 2 weeks (P<0.01). Neuropsychological assessments showed that there was no significant difference between the two groups except for the significant improvement in the categories on WCST in study group compared to the baseline (P<0.05) and the control group (P<0.05)after 2 weeks treatment. No serious event occurred in the patients during the rTMS study. CONCLUSION: 10 Hz rTMS enhances early effects of citalopram and improves cognitive function in first-episode major depressive patients.

RESUMO

BACKGROUND: With the modification of DSM-5 mixed features specifier, a brief scale to screen mixed features in patients with mood disorders is needed in clinical practice. This study aimed to explore the psychometric properties of the Chinese version of the Clinically Useful Depression Outcome Scale supplemented with DSM-5 Mixed subtype (CUDOS-M-C) for the Chinese patients with mood disorders. METHODS: Overall, 300 patients with major depressive episode were recruited. All participants were assessed using CUDOS-M-C, Young Mania Rating Scale, Hamilton Anxiety Scale and Montgomery-Asberg Depression Rating Scale. The receiver operating characteristic (ROC) curve analysis was used to calculate the optimal cut-off values of CUDOS-M-C score. The reliability and validity of CUDOS-M-C were examined using Cronbach's alpha, intraclass correlation coefficient (ICC) and principal component analysis (PCA). RESULTS: The results of PCA indicated two-factor structure as the best solution for CUDOS-M-C, which explained 54.82% of cumulative variance. The Cronbach's alpha was 0.892 and the ICC was 0.853. The area under the ROC curve of the CUDOS-M-C for participants with mixed depression was 0.927 (p<0.001) and the suitable cut-off value was 8, with a sensitivity of 91.6% and specificity of 79.9%. LIMITATIONS: Most of the patients were recruited from eastern China and further research with larger sample is warranted. And this study did not perform confirmatory factor analysis to identify the generalization of factor structure of CUDOS-M-C. Besides, the study performed the test-retest reliability of CUDOS-M-C and further analysis is needed to ascertain the patient's post-treatment changes. CONCLUSION: The CUDOS-M-C demonstrated to have satisfactory psychometric properties as a self-report scale, and could be applied to screen patients with mixed depression in clinical practice.

RESUMO

Epidemiological studies have demonstrated that the genetic factors partly influence the development of same-sex sexual behavior, but most genetic studies have focused on people of primarily European ancestry, potentially missing important biological insights. Here, we performed a two-stage genome-wide association study (GWAS) with a total sample of 1478 homosexual males and 3313 heterosexual males in Han Chinese populations and identified two genetic loci (rs17320865, Xq27.3, FMR1NB, Pmeta = 8.36 × 10-8, OR = 1.29; rs7259428, 19q12, ZNF536, Pmeta = 7.58 × 10-8, OR = 0.75) showing consistent association with male sexual orientation. A fixed-effect meta-analysis including individuals of Han Chinese (n = 4791) and European ancestries (n = 408,995) revealed 3 genome-wide significant loci of same-sex sexual behavior (rs9677294, 2p22.1, SLC8A1, Pmeta = 1.95 × 10-8; rs2414487, 15q21.3, LOC145783, Pmeta = 4.53 × 10-9; rs2106525, 7q31.1, MDFIC, Pmeta = 6.24 × 10-9). These findings may provide new insights into the genetic basis of male sexual orientation from a wider population scope. Furthermore, we defined the average ZNF536-immunoreactivity (ZNF536-ir) concentration in the suprachiasmatic nucleus (SCN) as lower in homosexual individuals than in heterosexual individuals (0.011 ± 0.001 vs 0.021 ± 0.004, P = 0.013) in a postmortem study. In addition, compared with heterosexuals, the percentage of ZNF536 stained area in the SCN was also smaller in the homosexuals (0.075 ± 0.040 vs 0.137 ± 0.103, P = 0.043). More homosexual preference was observed in FMR1NB-knockout mice and we also found significant differences in the expression of serotonin, dopamine, and inflammation pathways that were reported to be related to sexual orientation when comparing CRISPR-mediated FMR1NB knockout mice to matched wild-type target C57 male mice.

RESUMO

We explored the psychological changes in suspected patients during the coronavirus disease 2019 (COVID-19) epidemic and obtained evidence for early psychological guidance and intervention in this group. A total of 31 inpatients with suspected COVID-19 were identified at our hospital. The depression module of the Patient Health Questionnaire (PHQ-9), the General Anxiety Disorder (GAD)-7 scale, and the Self-Reporting Questionnaire (SRQ-20) mental health self-assessment questionnaire were used to assess depression, anxiety, and overall mental health. Among the patients, 32.3% had symptoms of depression and 19.4% had symptoms of anxiety. Levels of anxiety and fear varied. In comparing the PHQ-9 and 7-item Generalized Anxiety Disorder Scale scores of suspected and confirmed patients, there was no significant difference in the distribution of severity of anxiety or depression in the 2 groups. The PHQ-9 scores indicated mild depression symptoms in 25.8% of suspected patients, moderate symptoms in 0%, and severe symptoms in 6.5%. Overall, 50% of confirmed patients had symptoms, with 30.8% classified as mild, 15.4% classified as moderate, and 3.8% classified as severe. The 7-item Generalized Anxiety Disorder Scale scores in the group of suspected patients showed that 9.7% had mild symptoms, 0% had moderate symptoms, and 9.7% had severe symptoms. In the group of confirmed patients, 38.4% had symptoms (34.6% mild, 0% moderate, and 3.8% severe). Diagnosed patients had more visible symptoms of depression and different total PHQ-9 scores. During the COVID-19 epidemic, suspected and diagnosed patients had different levels of mental health problems. Diagnosed patients had more visible symptoms. The performance of suspected patients was higher, but their mental state was more polarized. It may thus be important to monitor the psychological state of suspected patients as early as possible to enable timely interventions that promote psychological rehabilitation.

RESUMO

BACKGROUND: Novel coronavirus disease 2019 (COVID-19) was first found in Wuhan, China, and it has rapidly spread worldwide since the end of 2019. There is an urgent need to treat the physical and psychological aspects of COVID-19. Interpersonal psychotherapy (IPT)-based psychological intervention is an evidence-based therapy for depression and post-traumatic stress disorder. CASE SUMMARY: This report describes a case of COVID-19 in a patient who transmitted the disease to his entire family. The patient received four sessions of IPT-based psychological intervention. We used the Hamilton Rating Scale for Depression and Patient Health Questionnaire to measure depression level, and the Hamilton Anxiety Scale and Generalized Anxiety Disorder to measure anxiety among the patients. CONCLUSION: This case shows that IPT-based therapy can reduce COVID-19 patient depression and anxiety and the advantage of IPT-based therapy.

RESUMO

At the end of 2019, a new form of pneumonia disease known as the corona virus disease 2019 (COVID-19) rapidly spread throughout most provinces of China, and the total global number of COVID-19 cases has surpassed 500 000 by Mar. 27, 2020 (WHO, 2020). On Jan. 30, 2020, the World Health Organization (WHO) declared COVID-19 a global health emergency (WHO, 2020). COVID-19 causes most damage to the respiratory system, leading to pneumonia or breathing difficulties. The confirmed case fatality risk (cCFR) was estimated to be 5% to 8% (Jung et al., 2020). Besides physical pain, COVID-19 also induces psychological distress, with depression, anxiety, and stress affecting the general population, quarantined population, medical staff, and patients at different levels (Kang et al., 2020; Xiang et al., 2020). Previous research on patients in isolation wards highlighted the risk of depressed mood, fear, loneliness, frustration, excessive worries, and insomnia (Abad et al., 2010).

RESUMO

Public health crises, such as the outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) since Dec. 2019, are widely acknowledged as severe traumatic events that impose threats not only because of physical concerns but also because of the psychological distress of infected patients. We designed an internet-based integrated intervention and evaluated its efficacy on depression and anxiety symptoms in patients infected by SARS-CoV-2.

RESUMO

BACKGROUND: Sexual orientation has been suggested to affect executive function, of which the neurobiological basis is still largely unknown. In this study, we explored the interrelationship between neuropsychological characteristics in homosexual and heterosexual men and their anatomical connectome by graph theoretical analysis. METHODS: Fifty-three homosexual and 47 heterosexual males underwent diffusion tensor magnetic resonance imaging (MRI) and neuropsychological assessments. Whole-brain anatomical networks were constructed using white matter tractography, performed on the diffusion tensor imaging data. Neuropsychological tests included the Wisconsin Card Sorting Test (WCST), the Continuous Performance Test (CPT) and the Trail-Making Test (TMT). RESULTS: The cognitive performance of homosexual men was significantly poorer than their heterosexual counterparts in terms of WCST total correct responses. Anatomical connectome analysis revealed a lower (P=0.001) anatomical connectivity between left PoCG and left SMG (P=0.003) in homosexual men as compared to heterosexual men. Linear regression analyses showed that the WCST total correct responses score was significantly linked with sexual orientation (P=0.001). The anatomical connectivity strength between left PoCG and left SMG was also shown to be significantly correlated with sexual orientation (P=0.039) and education (P=0.047). CONCLUSIONS: Our study demonstrated the differences in the performance of WCST and anatomical connectome of large-scale brain networks between homosexual and heterosexual men, extending our understanding of the brain's circuitry and the characteristics of executive function in men of different sexual orientation.

RESUMO

OBJECTIVE: To study the nephrotoxicity tacrolimus (FK506) at the therapeutic dose the preventive effect of diltiazem (Dil), a calcium antagonist against the FK506-induced pathological changes. METHODS: 24 Sprague-Dawley male rats were randomly divided into 4 equal groups: cyclosporine A (CsA) group, undergoing treatment of CsA at the therapeutic dose after kidney transplantation (25 mg x kg(-1) x d(-1)) for 4 weeks, FK506 group treated with FK506 (0.8 mg x kg(-1) x d(-1)), FK506 + Dil group treated with FK506 (0.8 mg x kg(-1) x d(-1)) and Dil at the dose of 8 mg x kg(-1) x d(-1), and control group. Four weeks later body weight was measured and 24 h urine sample was collected. Then the rats were killed. Their kidneys underwent light and transmission electron microscopy. RESULTS: The body weight ad weight gain, and the weights of both kidney of the CsA group were all significantly lower than those of the other 3 groups (all P < 0.05), and there were not significant differences in there parameters among the other 3 groups. The serum creatinine levels of the FK506 and CsA groups were (36.0 +/- 2.6) and (34.2 +/- 4.5) micromol/L respectively, both significantly higher than those of the FK506 + Dil and control groups [(28.5 +/- 2.1) and (29.2 +/- 3.428) micromol/L respectively, all P < 0.05], however, there was no significant difference between the FK506 + Dil and control groups. The creatinine clearance rate of the FK506 and CsA groups were (0.63 +/- 0.45) and (0.58 +/- 0.39) ml x min(-1) x 100 g(-1) respectively, significantly lower than those of the FK506 + Dil and control groups [(1.55 +/- 0.91) and (1.02 +/- 0.62) mlxmin(-1) x 100 g(-1) respectively, all P < 0.05]. Pathological examination showed epithelial cell cloudy swelling and vacuolization and interstitial fibrosis in the renal tubules, mitochondria swelling and vacuolization in renal tubular epithelial cells, renal arteriole hyalinization, and foot cell conjugation glomerulus, mitochondria swelling and vacuolization in the FK506 and CsA groups, and such changes were relatively mild in the FK506 + Dil group. CONCLUSION: FK506 at renal transplantation therapeutic dose, as well as CsA, induces pathological changes in renal tissues and ultrastructural organization. Dil is able to prevent FK506-induced these pathological changes.

RESUMO

OBJECTIVE: To quickly assess the psychological status of the wounded who were transferred in the earthquake and their family members, as to promoting the system of psychological crisis intervention. METHODS: The triage assessment system was used to the 44 wounded and 37 family members, additionally, the Hamilton Depression Rating Scale (HAMD), and Hamilton Anxiety Rating Scale (HAMA) for related analysis were also administrated to verify the effectiveness of screening of the triage assessment system. RESULTS: Of the 79 wounded and their families in the triage assessment system, the score of emotion in the wounded group was (3.07 +/- 1.38), the score of cognition was (2.34 +/- 1.39), the score of behavior was (2.71 +/- 1.47), and the total score was (8.12 +/- 3.69); the score of emotion in the family group was (2.51 +/- 1.27), the score of cognition was (1.57 +/- 0.85), the score of behavior was (1.71 +/- 1.02), and the total score was (5.80 +/- 2.61). There were significant differences in the family and the wounded group in cognition, behavior and the total (t(cognition) = 2.853, P = 0.006; t(behavior) = 3.366, P = 0.001; t(total) = 3.116, P = 0.003). Both the depression and anxiety symptoms in the Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA) were 11.48 +/- 7.62, 9.23 +/- 5.64, and 8.49 +/- 4.87, 9.38 +/- 7.05, respectively. In the emotion, cognition, behavior and total scores of the triage assessment system related to higher with HAMD and HAMA were r(emotion-HAMD) = 0.393, P = 0.001; r(emotion-HAMA) = 0.443, P = 0.000; r(cognition-HAMD) = 0.434, P = 0.000; r(cognition-HAMA) = 0.240, P = 0.037; r(behavior-HAMD) = 0.529, P = 0.000; r(behavior-HAMA) = 0.256, P = 0.026; r(total-HAMD) = 0.517, P = 0.000; r(total-HAMA) = 0.369, P = 0.001. CONCLUSION: The triage assessment system should be the reliable method for an assessment featured by a rapid, accurate and simple one in screening and monitoring.

RESUMO

OBJECTIVE: To detect the reliability and validity of the self-reporting questionnaire (SRQ-20), and to make a rapid assessment on mental health among victims in sudden crisis. METHODS: The SRQ-20 which is on appendix of the Ministry of Health adopted as "emergency psychological crisis intervention guiding principles" was administrated among 1222 victims in Wenchuan earthquake. The reliability of the questionnaire was tested by split-half coefficient and Cronbach's alpha coefficient; the validity was tested by means of principal component factor analysis. RESULTS: The self-reporting questionnaire and split-half coefficient was 0.748, each item of Cronbach's alpha in the reliability coefficient was between in 0.778 to 0.789, overall Cronbach's alpha in the reliability coefficient was 0.792. There were five main components in principal component factor analysis: lacking of power, somatization/biological symptoms, depression thought, emotions and awareness. CONCLUSION: The self-reporting questionnaire (SRQ-20) should have good reliability, and validity, and China's psychological crisis intervention in processing assessment of the mental health should be a fast, accurate and effective screening tool.

RESUMO

OBJECTIVE: To investigate the effects of androgen on sexually dimorphism nucleus in preoptic area (SDN-POA) and anteroventral periventricular nucleus (AVPV) before sexual differentiation of the brain in female rats. METHODS: Neonatal female SD rats (n=12) were randomly divided into two groups: androgen group and control group. Twenty-four hours after birth animals were subjected to intraperitoneal injection of 50 microl of testosterone propionate (TP,10.0 g/L) or aseptic oil as control. The rats were sacrificed 60 days after the injection and the brains were collected for crystal violet staining. LEICA Q Win system was applied in detecting the boundaries of SDN-POA and AVPV, then the volumes of SDN-POA and AVPV were calculated. RESULTS: The volumes of SDN-POA in androgen group were significantly larger than those in control group [(16.77+/-2.68) vs (8.99+/-1.42)mm(3)x10(-3), P<0.01], while the volumes of AVPV in androgen group were significantly smaller than those in control group [(9.14+/-1.16) vs (14.62+/-2.80)mm(3)x10(-3), P<0.01]. CONCLUSION: Exogenous androgen rendered before sexual differentiation in female rats results in enlargement of SDN-POA volumes and reduction of AVPV.

RESUMO

OBJECTIVE: To compare the differences between homosexual and heterosexual men in the pattern of induced aversive emotion regulation. METHODS: Ten healthy homosexual men and 10 heterosexual men were investigated by functional magnetic resonance imaging under three types of visual sexual stimuli designed by Block. SPM2 software was used for data analysis. RESULTS: Same levels of negative emotions of homosexual men and heterosexual were induced by female-female and male-male erotic stimuli respectively. Activations of same brain regions including prefrontal gyrus, temporal gyrus, occipital gyrus and cerebellum were observed in two groups. However, there were significant differences in the side of hippocampus and precuneus. Activations of right cingulate cortex were observed in homosexual men, but not in heterosexual men. CONCLUSION: There are some differences in the patterns of aversive emotion regulation between homosexual and heterosexual men.

RESUMO

OBJECTIVE: To study the nephrotoxicity induced by first oral administration of tacrolimus (FK506) and the prevention of diltiazem (Dil). METHODS: 24 Sprague-Dawley male rats were randomly divided into 4 equal groups: control (n = 6), cyclosporine A (CsA) group (receiving CsA 25 mg.kg(-1).d(-1) so as to develop CsA-induced nephropathy model), FK506 group (receiving FK506 0.8 mg.kg(-1).d(-1), the common renal transplantation therapeutic dose, so as to develop FK506-induced nephropathy model), FK506 + Dil group (receiving CsA 0.8 mg.kg(-1).d(-1) and Dil 8 mg.kg(-1).d(-1)), and control group. Four weeks later body weight was measured, blood samples were collected to examine the creatinine, urea nitrogen, and uric acid, and urine samples were collected to examine the 24 h urine protein, uric acid, and creatinine. Then the rats were killed with their kidneys taken out to undergo histopathological examination. RESULTS: The urine creatinine levels of the CsA and FK506 groups were significantly lower than that of the control group (both P < 0.05), however, there was no significant difference in urine creatinine between the FK506 + Dil group and control group. The blood creatinine levels of both CsA and FK506 groups were significantly higher than those of the FK506 + Dil group and control group (all P < 0.05), however, there was no significant difference in blood creatinine between the FK506 + Dil group and control group. The urea nitrogen level of the CsA group was significantly higher than those of the other 3 groups (all P < 0.05). The creatinine clearance rates of the CsA and FK506 groups were both significantly lower than that of the control group (both P < 0.05), and the creatinine clearance rate of the FK506 + Dil group was between those of the FK506 group and control group, however, with significant differences with both of them. Histopathology examination showed cloudy swelling and vacuolization of the renal tubular epithelial cells in the CsA and FK506 groups. However, the pathological changes of the FK506 + Dil group were remarkably milder in comparison with these 2 groups. CONCLUSION: FK506 and CsA at the renal transplantation therapeutic dose induce nephrotoxicity. Diltiazem prevents FK506-induced nephrotoxicity.

RESUMO

The present study aimed to explore the possible associations between the dorsolateral prefrontal cortex (DLPFC) metabolites and the cognitive function in first-episode schizophrenia (FES).This study included 58 patients with FES (29 males and 29 females; mean age, 22.66 ±â€Š7.64 years) recruited from the First Affiliated Hospital, College of Medicine, Zhejiang University, and 43 locally recruited healthy controls (16 males and 27 females; mean age, 23.07 ±â€Š7.49 years). The single-voxel proton magnetic resonance spectroscopy was used to measure the levels of N-acetylaspartate (NAA); complex of glutamate, glutamine, and γ-aminobutyric acid (Glx); choline-containing compounds; and myo-inositol in the DLPFC. The ratios of metabolites to creatine (Cr) were calculated. The cognitive function was assessed by Measurement and Treatment Research to Improve Cognition in Schizophrenia Consensus Cognitive Battery (MCCB). Correlation analysis was used to assess the relationships between the DLPFC metabolites and the cognitive function.Compared with the healthy controls, the patients with FES showed significantly reduced scores in each part of the MCCB, significantly reduced NAA/Cr, and significantly increased Glx/Cr in the left DLPFC. Poor performance in verbal learning and visual learning was correlated to the reduced NAA/Cr ratio in the left DLPFC.These findings suggest that a lower NAA/Cr ratio in the left DLPFC is associated with the cognitive deficits in patients with FES, and may be an early biochemical marker for the cognitive impairment in schizophrenia.

RESUMO

This study aimed to investigate the less known activation pattern of T lymphocyte populations and immune checkpoint inhibitors on immunocytes in patients with bipolar II disorder depression (BD) or major depression (MD). A total of 23 patients with BD, 22 patients with MD, and 20 healthy controls (HCs) were recruited. The blood cell count of T lymphocyte subsets and the plasma level of cytokines (IL-2, IL-4, IL-6, IL-10, TNF-α, and IFN-γ) were selectively investigated. The expression of T-cell immunoglobulin and mucin-domain containing-3 (TIM-3), programmed cell death protein 1 (PD-1) and its ligands, PD-L1 and PD-L2, on T lymphocytes and monocytes, was detected. In results, blood proportion of cytotoxic T cells significantly decreased in BD patients than in either MD patients or HCs. The plasma level of IL-6 increased in patients with BD and MD. The expression of TIM-3 on cytotoxic T cells significantly increased, whereas the expression of PD-L2 on monocytes significantly decreased in patients with BD than in HCs. These findings extended our knowledge of the immune dysfunction in patients with affective disorders.

RESUMO

The clinical and cognitive responses to repetitive transcranial magnetic stimulation (rTMS) in bipolar II depressed patients remain unclear. In this study, thirty-eight bipolar II depressed patients were randomly assigned into three groups: (i) left high-frequency (n = 12), (ii) right low-frequency (n = 13), (iii) sham stimulation (n = 13), and underwent four-week rTMS with quetiapine concomitantly. Clinical efficacy was evaluated at baseline and weekly intervals using the 17-item Hamilton Depression Rating Scale (HDRS-17) and Montgomery-Asberg Depression Rating Scale (MADRS). Cognitive functioning was assessed before and after the study with the Wisconsin Card Sorting Test (WCST), Stroop Word-Color Interference Test (Stroop), and Trail Making Test (TMT). Thirty-five patients were included in the final analysis. Overall, the mean scores of both the HDRS-17 and the MADRS significantly decreased over the 4-week trial, which did not differ among the three groups. Exploratory analyses revealed no differences in factor scores of HDRS-17s, or in response or remission rates. Scores of WCST, Stroop, or TMT did not differ across the three groups. These findings indicated active rTMS combined with quetiapine was not superior to quetiapine monotherapy in improving depressive symptoms or cognitive performance in patients with bipolar II depression.
