Neural and Cognitive Predictors of Stimulant Treatment Efficacy in Medication-Naïve ADHD Adults: A Pilot Diffusion Tensor Imaging Study.

OBJECTIVE: Stimulant medications are the main treatment for Attention Deficit Hyperactivity Disorder (ADHD), but overall treatment efficacy in adults has less than a 60% response rate. This study aimed to identify neural and cognitive markers predictive of longitudinal improvement in response to stimulant treatment in drug-naïve adults with ADHD. METHOD: We used diffusion tensor imaging (DTI) and executive function measures with 36 drug-naïve adult ADHD patients in a prospective study design. RESULTS: Structural connectivity (measured by fractional anisotropy, FA) in striatal regions correlated with ADHD clinical symptom improvement following stimulant treatment (amphetamine or methylphenidate) in better medication responders. A significant positive correlation was also found between working memory performance and stimulant-related symptom improvement. Higher pre-treatment working memory scores correlated with greater response. CONCLUSION: These findings provide evidence of pre-treatment neural and behavioral markers predictive of longitudinal treatment response to stimulant medications in adults with ADHD.

Effectiveness of a targeted brief intervention for recent suicide attempt survivors: a randomised controlled trial protocol.

INTRODUCTION: Effective, brief, low-cost interventions for suicide attempt survivors are essential to saving lives and achieving the goals of the National Strategy for Suicide Prevention and Zero Suicide. This study aims to examine the effectiveness of the Attempted Suicide Short Intervention Program (ASSIP) in averting suicide reattempts in the United States healthcare system, its psychological mechanisms as predicted by the Interpersonal Theory of Suicide, and the potential implementation costs, barriers and facilitators for delivering it. METHODS AND ANALYSIS: This study is a hybrid type 1 effectiveness-implementation randomised controlled trial (RCT). ASSIP is delivered at three outpatient mental healthcare clinics in New York State. Participant referral sites include three local hospitals with inpatient and comprehensive psychiatric emergency services, and outpatient mental health clinics. Participants include 400 adults who have had a recent suicide attempt. All are randomised to 'Zero Suicide-Usual Care plus ASSIP' or 'Zero Suicide-Usual Care'. Randomisation is stratified by sex and whether the index attempt is a first suicide attempt or not. Participants complete assessments at baseline, 6 weeks, and 3, 6, 12 and, 18 months. The primary outcome is the time from randomisation to the first suicide reattempt. Prior to the RCT, a 23-person open trial took place, in which 13 participants received 'Zero Suicide-Usual Care plus ASSIP' and 14 completed the first follow-up time point. ETHICS AND DISSEMINATION: This study is overseen by the University of Rochester, with single Institutional Review Board (#3353) reliance agreements from Nathan Kline Institute (#1561697) and SUNY Upstate Medical University (#1647538). It has an established Data and Safety Monitoring Board. Results will be published in peer-reviewed academic journals, presented at scientific conferences, and communicated to referral organisations. Clinics considering ASSIP may use a stakeholder report generated by this study, including incremental cost-effectiveness data from the provider point of view. TRIAL REGISTRATION NUMBER: NCT03894462.

Individuals who text crisis text line: Key characteristics and opportunities for suicide prevention.

OBJECTIVE: Text-based crisis services are increasingly prominent, with inclusion in the national 988 crisis number launching in 2022. Yet little is known about who uses them. This study seeks to understand the population served by Crisis Text Line (CTL), the largest crisis text service in the United States. METHODS: Secondary data analysis was conducted on de-identified Crisis Counselor reports, texter post-conversation survey responses, and anonymized text conversation data from 85,877 texters who contacted CTL during a 12-month period. We examined Crisis Counselor's ratings of suicide ideation severity, texters' reports of race, gender, sexual orientation, recent mental health symptoms, and additional sources of help, and logs of frequency of contact. RESULTS: 76% of texters were under 25. 79% were female. 48% identified as other than heterosexual/straight. 64% had only one conversation. 79% were above the clinical cutoff for depression and 80% for anxiety, while 23% had thoughts of suicide. 23% received help from a doctor or therapist, and 28% received help only from CTL. CONCLUSIONS: CTL reaches a highly distressed, young, mostly female population, including typically underserved minorities and a substantial percentage of individuals who do not receive help elsewhere. These findings support the decision to include texting in the forthcoming national 988 implementation.

Crisis text-line interventions: Evaluation of texters' perceptions of effectiveness.

OBJECTIVE: Crisis Text Line (CTL), the largest provider of text-based crisis intervention services in the U.S., has answered nearly 7 million conversations since its inception in 2013. The study's objective was to assess texter's perceptions of the effectiveness of CTL crisis interventions. METHOD: Survey data completed by 85,877 texters linked to volunteer crisis counselor (CC) reports from October 12, 2017, to October 11, 2018 were analyzed. The relationship of several effectiveness measures with texters' demographic and psychosocial characteristics, frequency of CTL usage, and texters' perceptions of engagement with their CCs was examined using a series of logistic regression analyses. RESULTS: By the end of the text-based conversation, nearly 90% of suicidal texters reported that the conversation was helpful, and nearly half reported being less suicidal. CONCLUSIONS: Our study offers evidence for CTL's perceived effectiveness. These findings are of critical importance in light of the launch of a nationwide three-digit number (988) for suicide prevention and mental health crisis supports in the U.S., which will include texting.

Association between frontal cortico-limbic white-matter microstructure and risk for pediatric depression.

This study aimed to identify white-matter microstructural characteristics associated with risk for pediatric major depressive disorder (MDD) measured by the Child Behavior Checklist (CBCL) Anxiety/Depression scores. Children (N = 32) of both sexes, aged 6-12, underwent T1-weighted whole-head anatomical and diffusion-weighted imaging. Each participant's mean diffusion measure image was generated and thinned to create an alignment-invariant tract representation. Voxel-wise analysis on the resulting map was carried out in Track Based Spatial Statistics (TBSS) using general linear models by regressing the CBCL-Anxiety/Depression score against measures of diffusion tensor imaging (DTI). We also compared these results with prior DTI findings from the same children associated with CBCL-Emotion Dysregulation profile, an indicator for bipolar disorder. TBSS voxel-wise analysis showed a significant negative correlation between fractional anisotropy (FA) and CBCL-Anxiety/Depression scores localized in the right anterior cingulum and connected corpus callosal region. The negative FA correlations in these regions were greater in CBCL-Anxiety/ Depression scores compared to CBCL-Emotional Dysregulation scores. Reduced white-matter connectivity in the anterior cingulum and connected corpus callosal region may represent a biomarker of risk for pediatric MDD. These results may help identify brain differences associated with the development of MDD, and assist with earlier clinical identification of pediatric MDD.

Differentiating bipolar disorder from unipolar depression in youth: A systematic literature review of neuroimaging research studies.

Differentiating bipolar disorder from unipolar depression is one of the most difficult clinical questions posed in pediatric psychiatric practices, as misdiagnosis can lead to severe repercussions for the affected child. This study aimed to examine the existing literature that investigates brain differences between bipolar and unipolar mood disorders in children directly, across all neuroimaging modalities. We performed a systematic literature search through PubMed, PsycINFO, Embase, and Medline databases with defined inclusion and exclusion criteria. Nine research studies were included in the systematic qualitative review, including three structural MRI studies, five functional MRI studies, and one MR spectroscopy study. Relevant variables were extracted and brain differences between bipolar and unipolar mood disorders in children as well as healthy controls were qualitatively analyzed. Across the nine studies, our review included 228 subjects diagnosed with bipolar disorder, 268 diagnosed with major depressive disorder, and 299 healthy controls. Six of the reviewed studies differentiated between bipolar and unipolar mood disorders. Differentiation was most commonly found in the anterior cingulate cortex (ACC), insula, and dorsal striatum (putamen and caudate) brain areas. Despite its importance, the current neuroimaging literature on this topic is scarce and presents minimal generalizability.

Can the CANTAB identify adults with attention-deficit/hyperactivity disorder? A controlled study.

We examined the diagnostic utility of the Cambridge Neuropsychological Test Automated Battery (CANTAB) for identifying adults with attention-deficit/hyperactivity disorder (ADHD). The sample consisted of clinically referred adults aged 18 to 60 years old, with (n = 474) and without (n = 163) DSM-IV diagnosis of ADHD. All subjects were administered seven subtests from the CANTAB that targeted domains of executive functioning and verbal memory. Data were analyzed to identify which CANTAB tasks would best predict ADHD status. Our results failed to show any diagnostic utility for the CANTAB in adults with ADHD, even when using the most robust tests (Affective Go/No-go [AGN] Total Commissions and [RTI] Simple Reaction Time) identified from stepwise logistic regression (forward selection; p > 0.05 for entry). However, the CANTAB was helpful in identifying executive functioning disorder (EFD) in adults with ADHD when compared with controls subjects. Even though the CANTAB lacked diagnostic utility for adults with ADHD, the findings provided further evidence that adult ADHD is strongly associated with EFD. This study represents the most comprehensive evaluation of the diagnostic utility of the CANTAB in a clinical sample of adults with ADHD.

Cingulum-Callosal white-matter microstructure associated with emotional dysregulation in children: A diffusion tensor imaging study.

Emotional dysregulation symptoms in youth frequently predispose individuals to increased risk for mood disorders and other mental health difficulties. These symptoms are also known as a behavioral risk marker in predicting pediatric mood disorders. The underlying neural mechanism of emotional dysregulation, however, remains unclear. This study used the diffusion tensor imaging (DTI) technique to identify anatomically specific variation in white-matter microstructure that is associated with pediatric emotional dysregulation severity. Thirty-two children (mean age 9.53 years) with varying levels of emotional dysregulation symptoms were recruited by the Massachusetts General Hospital and underwent the DTI scans at Massachusetts Institute of Technology. Emotional dysregulation severity was measured by the empirically-derived Child Behavior Checklist Emotional Dysregulation Profile that includes the Attention, Aggression, and Anxiety/Depression subscales. Whole-brain voxel-wise regression tests revealed significantly increased radial diffusivity (RD) and decreased fractional anisotropy (FA) in the cingulum-callosal regions linked to greater emotional dysregulation in the children. The results suggest that microstructural differences in cingulum-callosal white-matter pathways may manifest as a neurodevelopmental vulnerability for pediatric mood disorders as implicated in the clinical phenotype of pediatric emotional dysregulation. These findings may offer clinically and biologically relevant neural targets for early identification and prevention efforts for pediatric mood disorders.

An innovative SMS intervention to improve adherence to stimulants in children with ADHD: Preliminary findings.

BACKGROUND: Although large datasets document that stimulants decrease the risk for many adverse ADHD-associated outcomes, compliance with stimulants remains poor. AIMS: This study examined the effectiveness of a novel ADHD-centric text messaging-based intervention aimed to improve adherence to stimulant medications in children with ADHD. METHODS: Subjects were 87 children aged 6-12, who were prescribed a stimulant medication for ADHD treatment. Prescribers gave permission to contact their patients for participation in the study. Subjects were primarily from the primary care setting with a subsample of psychiatrically referred subjects for comparison. Age- and sex-matched comparators were identified (3:1) from the same pool of prescriber-approved subjects that did not participate. Timely prescription refills (within 37 days) were determined from prescription dates documented in patients' electronic medical record. RESULTS: Eighty-five percent of SMS intervention patients refilled their prescriptions in a timely manner compared with 62% of patients receiving treatment as usual (OR = 3.46, 95% CI: 1.82, 6.58; p < 0.001). The number needed to treat statistic was computed as five, meaning for every five patients who receive the SMS intervention, we can keep one adherent to their stimulant treatment. CONCLUSIONS: These preliminary findings support the potential utility of a readily accessible technology to improve the poor rate of adherence to stimulant treatment in children with ADHD. To the best of our knowledge, this study is the first digital health intervention aimed at improving adherence to stimulant medication for children with ADHD. These results support the need for further examination of this technology through more definitive randomized clinical trials.

An integrative dance class to improve physical function of people with developmental and intellectual disabilities: a feasibility study.

Background: This paper examines the feasibility of utilizing an integrative contemporary dance class for improving physical function in adults with developmental and intellectual disabilities. Methods: Eighteen individuals participated in a 12-week dance class alongside 11 matriculated college students registered in an integrative dance course. Lower extremity strength, flexibility, mobility and balance testing was measured at pre- and post- testing. The dance class comprised 60 min of dance training two times per week. College students participated by dancing alongside the individuals in the class and assisting, if required. Results: Significant improvements were found in lower extremity strength in all muscle groups tested, hamstring flexibility, generalized mobility and stability. Conclusions: Integrative contemporary dance may provide meaningful physical improvements for individuals with developmental and intellectual disabilities and are in need of further development and research.

Are subsyndromal manifestations of attention deficit hyperactivity disorder morbid in children? A systematic qualitative review of the literature with meta-analysis.

We conducted a qualitative review (n = 15 manuscripts) and meta-analysis (n = 9 manuscripts) of the extant literature to evaluate the prevalence and morbidity of subthreshold Attention Deficit Hyperactivity Disorder (ADHD). Our qualitative review showed that a sizable minority (mean: 17.7%) of clinically referred and non-referred children met a priori definitions of subthreshold ADHD. Those affected exhibited significantly higher rates of family dysfunction, cognitive impairment, executive dysfunction, interpersonal and school deficits, temperament problems, psychiatric comorbidity, and juvenile delinquency compared to children with no ADHD symptoms. These deficits were highly consistent with those observed in children with full threshold ADHD. These findings indicate that children with subthreshold ADHD symptoms are at significantly greater risk for negative outcomes in a wide range of non-overlapping functional domains worthy of further clinical and scientific consideration.

Subsyndromal Manifestations of Depression in Children Predict the Development of Major Depression.

OBJECTIVE: To evaluate the utility of assessing subsyndromal symptoms of major depressive disorder in childhood, indexed through the Child Behavior Checklist (CBCL) anxiety/depression scale, in predicting risk of developing major depressive disorder in adolescent and young adult years. STUDY DESIGN: The sample consisted of 537 children, 6-17 years of age, originally ascertained for a longitudinal family genetic study of youth with and without attention-deficit hyperactivity disorder and their first-degree relatives who were followed prospectively and blindly for 10 years from childhood into young adult years. Children with full diagnosis major depressive disorder at baseline were excluded. For analysis, the sample was stratified into 4 groups based on the presence or absence of parental mood disorders and by the presence or absence of subsyndromal scores on the CBCL anxiety/depression scale at baseline assessment in childhood. RESULTS: Children of parents with mood disorders plus subsyndromal scores on the CBCL anxiety/depression scale at baseline (n = 22) had the highest risk for developing major depressive disorder and anxiety disorders at the 10-year follow-up when compared with the other groups. Children with either subsyndromal scores on the CBCL anxiety/depression scale at baseline alone (n = 22) or parental mood disorders alone (n = 172) had intermediate outcomes. CONCLUSION: The CBCL anxiety/depression scale was useful in identifying children at high risk for the development of major depressive disorder and anxiety disorders at the 10-year prospective follow-up. Furthermore, our results emphasized the importance of familial psychiatric history in youth with subthreshold symptoms of depression. Parental mood disorder and subthreshold anxiety/depressive symptoms were predictive of developing depression.

Parental posttraumatic stress and child behavioral problems in world trade center responders.

BACKGROUND: We investigated trans-generational associations between Post Traumatic Stress Disorder (PTSD) symptoms in World Trade Center (WTC) responders and behavioral problems in their children. METHODS: Participants were WTC responders-8034 police and 8352 non-traditional (eg, construction workers)-with one or more children at the time of their first visit to the World Trade Center Health Program (WTC-HP). Self-report questionnaires were administered approximately 4 years after the 9/11 WTC attack. RESULTS: A total of 31.4% of non-traditional and 20.0% of police responders reported behavioral problems in their children. Non-traditional responder status, female sex, Hispanic ethnicity, more life stressors, more WTC-related PTSD symptoms, and dysphoric arousal symptoms were significant correlates of behavioral problems in responders' children. CONCLUSIONS: Specific parental sociodemographic, psychosocial and clinical characteristics, as well as PTSD symptom severity, were significant correlates of child behavior problems. Findings encourage monitoring and early intervention for children of disaster responders, particularly those at highest risk.
