Çiçek Zekey Ö, Uçar HN, Akyürek F, Arıcı Sağlıyan G, Çetin FH, Türkoğlu S, Altınbaş K. Neurotrophic factor levels and executive functions in children of parents with bipolar disorder: A case controlled study. J Affect Disord 2024; 359:327-332. [PMID: 38795781 DOI: 10.1016/j.jad.2024.05.112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 05/21/2024] [Accepted: 05/22/2024] [Indexed: 05/28/2024]
Abstract
BACKGROUND In the current study, it was aimed to evaluate neurotrophic factor levels and their relationship with executive functions in high-risk children and adolescents (high-risk group) whose parents were diagnosed with bipolar disorder (BD) but not affected by any psychiatric disease,and in order to determine possible vulnerability factors related to the disease. METHODS The study sample consisted of 32 high-risk group and 34 healthy controls. The Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version-Turkish Adaptation (KSADS-PL-T), Stroop Test, Serial Digit Learning Test (SDLT) and Cancellation Test to evaluate executive functions were administered to all participants by the clinician.Serum levels of neurotrophic factors were measured using commercial enzyme linked immunosorbent assay kits. RESULTS Serum BDNF, NT-3, NT-4 levels and SDLT scores were significantly lower in the high-risk group for BD compared to the healthy control group. A moderate negative correlation was found between BDNF levels and the Cancellation Test scores in the high-risk group. In addition to these results, the odds ratios of age, NT-4, SDLT scores for being in the risky group in terms of BD diagnosis were 1.26, 0.99 and 0.86 respectively. LIMITATIONS This was a cross-sectional study. Causality between study results is therefore difficult to establish. The relatively small sample size of the study is another limitation. CONCLUSION The results of the present study suggest that BDNF, NT-3, NT-4 may play a role in the physiopathology of BD and may be associated with impaired executive function areas such as attention and response inhibition in the high-risk group.

Abstract
Bipolar disorders (BP) are a class of psychiatric disorders with a complex symptom presentation. This systematic review aims to summarize literature pertaining to the misdiagnosis of pediatric BP using the DSM-IV and DSM-5 criteria, while emphasizing the negative impact that untreated BP has on life outcomes. This paper also attempts to outline and summarize available recommendations which may aid in improving diagnostic accuracy of pediatric BP. Scholars Portal Journals, PsychINFO, and MEDLINE databases were used to search articles until March 21, 2023. Inclusion criteria limited this review to articles published between 1995 and 2022 using a pediatric (age < 18) sample. Exclusion criteria omitted articles containing samples with self-reported diagnoses. A total of 15 articles are included in this review; study results were synthesized using a narrative summary. Youth with BP are most frequently misdiagnosed with attention-deficit hyperactive disorder (ADHD), schizophrenia, and major depressive disorder (MDD). Misdiagnosis can lead to inappropriate intervention plans and a delay in proper treatment, negatively impacting a child's quality of life by contributing to social, occupational, and economic adversity. Finally, this review addresses the need for future quantitative research on the implications of false negative diagnoses of pediatric BP.

Abstract
Editors' Note: The Editors would like to address issues related to the acceptance of this manuscript. The original manuscript referenced the study tool as the Bipolar Prodrome Symptom Interview Scale-Prospective (BPSS-P). After the manuscript's initial acceptance, the authors requested a revision of the tool name to Bipolar Prodrome Symptom Interview Scale-Full Perspective (BPSS-FP). When this request was made, the original acceptance was rescinded, and the authors were asked to formally revise and resubmit the manuscript with an explanation for the change. This revision and subsequent review led to the final acceptance of the manuscript. The authors have assured us that the tool used in the manuscript was the BPSS-FP (version 5) as opposed to abbreviated forms of this tool that are also used in research (e.g., Bipolar Prodrome Symptom Scale-Abbreviated Screen for Patients (BPSS-AS-P). Background: No scale exists to assess patients at-risk for bipolar disorder (BD) in Turkey. We aimed to assess the psychometric properties of the Turkish version of the Bipolar Prodrome Symptom Interview and Scale-Full Prospective (BPSS-FP). Method: Psychiatric service users aged 11-18 years old were interviewed using the BPSS-FP translated into Turkish and the Kiddie Schedule for Affective Disorders and Schizophrenia. Youth with major depressive disorder (MDD, n = 63), bipolar-spectrum disorder (n = 47), and healthy controls (n = 122) were included. Cronbach's alpha was calculated to assess internal consistency. The Young Mania Rating Scale (YMRS) and Children's Depression Rating Scale-Revised (CDRS-R) were administered to test convergent/discriminant validity. Discriminant validity was further tested using one-way ANOVA and "receiver operating characteristic" (ROC) curves. Inter-rater reliability was tested using correlation coefficients. Findings: Across 232 youth, Cronbach's alpha values were 0.932 for the BPSS-FP total score, 0.878 for the Mania Symptom Index, 0.887 for the Depression Symptom Index, and 0.797 for the General Symptom Index. Correlation coefficients for inter-rater reliability were high for the Mania Symptom Index (r = 0.989), Depression Symptom Index (r = 0.973), and General Symptom Index (r = 0.981). There were high correlations between the BPSS-FP Mania Symptom Index subscore and YMRS (r = 0.732), and the BPSS-FP Depression Symptom Index subscore and CDRS-R (r = 0.754), whereas cross-polarity correlations were non-significant. ROC analysis cut-off value was ≥21 for the BPSS-FP Mania Symptom Index between patients with BD and MDD (specificity = 85.7%, sensitivity = 78.7%). Conclusion: The Turkish version of the BPSS-FP has good psychometric properties and can be used in research. Longitudinal studies are needed to confirm the predictive value of the BPSS-FP.

Abstract
INTRODUCTION Visuospatial processing and task switching are impaired in individuals with mood disorders. It is unknown whether early deficits are present before mood symptom on set or are related to risk for a specific type of mood disorder. To investigate, we compared visual attention and task switching during sequencing among never-disordered youth with parental family histories of bipolar (BD) and major depressive disorders (MDD) and healthy controls (HC) with no personal or family history of psychopathology. METHOD 8-17-year-old youth of parents with BD (n = 31, "BD-risk"), youth of parents with MDD (n = 49, "MDD-risk"), and demographically similar HC (n = 31, "HC") were examined using the Delis-Kaplan Executive Functioning System Trail Making Test. Seed-based resting-state functional connectivity (RSFC) was collected from a subset of 88 participants (25 BD-risk, 37 MDD-risk, 26 HC) to investigate group differences in RSFC related to visuospatial processing. RESULTS BD-risk and MDD-risk offspring had impaired sequencing and task switching, demonstrated by reduced scores on visual scanning, F(2, 108) = 4.12, p = .02, number sequencing, F(2, 88) = 4.75, p = .01, letter sequencing, F(2, 108) = 4.24, p = .02, and number-letter sequencing, F(2, 108) = 4.66, p = .01, compared to scores in HC. RSFC between the posterior cingulate (PCC) and clusters in the subcallosal cortex, amygdala, and hippocampus significantly differed among HC, BD-risk, and MDD-risk groups. PCC-subcallosal/limbic RSFC was positively coupled in the MDD-risk and BD-risk groups and negatively coupled in HCs. CONCLUSIONS Youth at familial risk for mood disorders demonstrate visuospatial deficits early in the processing stream. Improved methods for identifying at-risk children with the earliest possible neurocognitive impairments may inform remediation strategies that could prevent mood disorders.

Abstract
OBJECTIVE To compare brain-derived neurotrophic factor (BDNF) levels between offspring of individuals with bipolar disorders (BD) and healthy controls (HCs) and investigate the effects of BDNF levels and body mass index (BMI) on brain structures. METHOD Sixty-seven bipolar offspring and 45 HCs were included (ages 8-28). Structural images were acquired using 3.0 Tesla magnetic resonance imaging. Serum BDNF levels were measured using enzyme-linked immunosorbent assay. Multivariate and univariate analyses of covariance were conducted. RESULTS Significantly higher BDNF levels were observed among bipolar offspring, relative to HCs (P > 0.025). Offspring status moderated the association between BDNF and BMI (F1 =4.636, P = 0.034). After adjustment for relevant covariates, there was a trend for a significant interaction of group and BDNF on neuroimaging parameters (Wilks'λ F56,94 =1.463, P = 0.052), with significant effects on cerebellar white matter and superior and middle frontal regions. Brain volume and BDNF were positively correlated among HCs and negatively correlated among bipolar offspring. Interactions between BDNF and BMI on brain volumes were non-significant among HCs (Wilks'λ F28,2 =2.229, P = 0.357), but significant among bipolar offspring (Wilks'λ F28,12 =2.899, P = 0.028). CONCLUSION Offspring status and BMI moderate the association between BDNF levels and brain structures among bipolar offspring, underscoring BDNF regulation and overweight/obesity as key moderators of BD pathogenesis.

Abstract
OBJECTIVES To describe the onset pattern, frequency, and severity of the signs and symptoms of the prodrome of the first hypomanic/manic episode and first depressive episode of bipolar disorder (BD) and to investigate the influence of a history of childhood maltreatment on the expression of prodromal symptoms. METHODS Using a semi-structured interview, the Bipolar Prodrome Symptom Scale-Retrospective (BPSS-R), information regarding prodromal symptoms was assessed from patients with a DSM-IV diagnosis of BD. History of childhood maltreatment was evaluated using the Childhood Trauma Questionnaire (CTQ). RESULTS Forty-three individuals with stable BD were included. On average, the prodrome of mania lasted 35.8 ± 68.7 months and was predominantly subacute or insidious, with rare acute presentations. The prodrome of depression lasted 16.6 ± 23.3 months and was also predominantly subacute or insidious, with few acute presentations. The prodromal symptoms most frequently reported prior to the first hypomanic or manic episode were mood lability, depressive mood, and impatience. A history of childhood abuse and neglect was reported by 81.4% of participants. Presence of childhood maltreatment was positively associated with prodromal symptoms, including social withdrawal, decreased functioning, and anhedonia. CONCLUSIONS This study provides evidence of a long-lasting, symptomatic prodrome prior to first hypomanic/manic and depressive episode in BD and suggests that a history of childhood maltreatment influences the manifestations of this prodrome.

Differentiation between major depressive disorder and bipolar disorder by auditory steady-state responses. J Affect Disord 2016; 190:800-806. [PMID: 26625092 DOI: 10.1016/j.jad.2015.11.034] [Citation(s) in RCA: 44] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2015] [Revised: 10/26/2015] [Accepted: 11/17/2015] [Indexed: 12/21/2022]
Abstract
BACKGROUND The auditory steady-state response (ASSR) elicited by gamma band neural oscillations has received considerable interest as a biomarker of psychiatric disorders. Although recent ASSR studies have reported that patients with bipolar disorder (BD) show altered ASSRs, little is known about ASSRs in patients with major depressive disorder (MDD). The aim of this study was to evaluate whether ASSRs in MDD subjects differed from those in BD subjects or normal controls (NC). METHOD We analyzed ASSRs in 14 MDD patients, 19 BD patients, and 29 normal control subjects. We used whole-head 306-channel magnetoencephalography to evaluate ASSR power and phase-locking factors (PLF) elicited by 20-, 30-, 40-, and 80-Hz click trains. We determined optimal sensitivity and specificity of ASSR power and PLF for the diagnosis of MDD or BD via receiver operating characteristic (ROC) curve analysis using a nonparametric approach. RESULTS MDD patients exhibited no significant differences in ASSR power or PLF compared with NC subjects, while BD patients showed deficits on the ASSR measures. MDD patients showed significantly larger ASSR power and PLF for 30-, 40-, and 80-Hz stimuli compared with BD patients. The area under the curve (AUC) for the ROC analysis (MDD vs. BD) was 0.81 [95% CI=0.66-0.96, p=0.003] concerning 40-Hz ASSR power. LIMITATIONS We could not exclude the effect of medication and the sample size of the current study is relatively small. CONCLUSIONS We could differentiate between MDD and BD subjects in terms of gamma band ASSR. Our data suggest that the 40-Hz ASSR may be a potential biomarker for differentiation between MDD and BD patients.

Abstract
AIM To compare patterns of sleep and the presence of sleep disturbances in individuals in at-risk mental states (ARMS) for psychosis and bipolar disorder (BD) with a healthy control (HC) group. METHODS This was a comparative study involving 20 individuals in ARMS for psychosis or BD, according to the Comprehensive Assessment of At-Risk Mental States, and 20 age- and sex-matched healthy controls. Quality of sleep in the previous month was assessed using the Pittsburgh Sleep Quality Index, diurnal somnolence was evaluated using The Epworth Sleepiness Scale, and chronotype was determined using the Questionnaire of Morningness/Eveningness (QME). All of the participants underwent polysomnography (PSG) during the entire night for two consecutive nights. The first night aimed to adapt the subject to the environment, and only the data from the second night were used for the analysis. RESULTS Compared with the HC group, individuals in the ARMS group reported significantly worse sleep quality, as measured by the Pittsburgh Sleep Quality Index. Both groups had scores consistent with daytime sleepiness on the Epworth Sleepiness Scale, and there were no differences with regard to chronotype between the groups, with a predominance of the indifferent type in both groups. In the PSG assessment, we observed increased Sleep Latency (SL) and increased Rapid Eye Movement Sleep Onset Latency (REMOL) in the ARMS group, compared to the HC group. CONCLUSION The results of this study indicated that sleep abnormalities could be found early in the course of mental diseases, even in at-risk stages, and support the further investigation of their predictive value in the transition to psychosis and BD.
