OBJECTIVE The clinical response of patients with bipolar disorder to medical treatment is variable. A better understanding of the underlying neural circuitry involved in bipolar treatment responsivity subtypes may provide insight into treatment resistance and aid in identifying an effective surgical target for deep brain stimulation (DBS) specific to the disorder. Despite considerable imaging research related to the disease, a paucity of comparative imaging analyses of treatment responsiveness exists. There are also no DBS targets designed expressly for patients with bipolar disorder. Therefore, the authors analyzed cingulum bundle axonal connectivity in relation to cortico-striatal-thalamo-cortical (CSTC) loops implicated in bipolar disorder across subjects who are responsive to treatment (RSP) and those who are refractory to therapy (REF), compared to healthy controls (HCs). METHODS Twenty-five subjects with bipolar disorder (13 RSP and 12 REF), diagnosed using the Mini International Neuropsychiatric Interview and classified with standardized rating scales, and 14 HCs underwent MRI with diffusion sequences for probabilistic diffusion-weighted tractography analysis. Image processing and tractography were performed using MRTrix. Region of interest (ROI) masks were created manually for 10 anterior cingulum bundle subregions, including surgical targets previously evaluated for the treatment of bipolar disorder (cingulotomy and subgenual cingulate DBS targets). Cortical and subcortical ROIs of brain areas thought to be associated with bipolar disorder and described in animal tract-tracing models were created via FreeSurfer. The number of axonal projections from the cingulum bundle subregion ROIs to cortical/subcortical ROIs for each group was compared. RESULTS Significant differences were found across groups involving cingulum bundle and CSTC loops. Subjects in the RSP group had increased connections from rostral cingulum bundle to medial orbitofrontal cortex, which is part of the limbic CSTC loop, whereas subjects in the REF group had increased connectivity from rostral cingulum bundle to thalamus. Additionally, compared to HCs, both RSP and REF subjects had decreased cingulum bundle dorsal connectivity (dorsal anterior/posterior cingulate, dorsomedial/lateral frontal cortex) and increased cingulum bundle ventral connectivity (subgenual cingulate, frontal pole, lateral orbitofrontal cortex) involving limbic and associative CSTC loops. CONCLUSIONS Findings demonstrate that bipolar treatment responsivity may be associated with significant differences in cingulum bundle connectivity in relation to CSTC loops, which may help identify a surgical target for bipolar disorder treatment via DBS in the future.

Objective To address the fact that Black adults (BAs) experience significantly greater stroke burden than the general population, we conducted a systematic literature review which described evidence-based interventions targeting secondary stroke risk reduction in BAs. Data Source Publications were selected from PubMed, Ovid, Cochrane, and Web of Science databases. We included peer-reviewed, longitudinal, English-language studies performed in the USA which reported results for BAs separately and had adult participants who had experienced stroke-related events. Results Six of the 7 studies employed behavioral interventions which promoted education on stroke risk factors, problem-solving skills, and healthy-coping strategies. These studies demonstrated improvements in one or more biologic outcomes including cholesterol control and systolic blood pressure. Conclusions Existing interventions on secondary stroke risk reduction approaches are effective in reducing secondary stroke risk among BAs, especially in individuals with poorly controlled blood pressure at baseline. However, additional research is needed because the current approaches may limit generalizability.

ObjectiveLiterature on older-age bipolar disorder (OABD) is limited. This first-ever analysis of the Global Aging & Geriatric Experiments in Bipolar Disorder Database (GAGE-BD) investigated associations among age, BD symptoms, comorbidity, and functioning.MethodsThis analysis used harmonized, baseline, cross-sectional data from 19 international studies (N=1377). Standardized measures included the Young Mania Rating Scale (YMRS), Hamilton Depression Rating Scale (HAM-D), Montgomery-Asberg Depression Rating Scale (MADRS), and Global Assessment of Functioning (GAF).ResultsMean sample age was 60.8years (standard deviation [SD] 12.2years), 55% female, 72% BD I. Mood symptom severity was low: mean total YMRS score of 4.3 (SD 5.4) and moderate-to-severe depression in only 22%. Controlled for sample effects, both manic and depressive symptom severity appeared lower among older individuals (p's&nbsp

OBJECTIVES: To identify facilitators and barriers of epilepsy self-management practices among Black children and caregivers. METHODS: Qualitative semi-structured in-depth interviews were conducted with 11 child-caregiver dyads (11 children with epilepsy and 11 caregivers). A deductive-inductive analysis was undertaken to describe the range of barriers and facilitators significant to participants. RESULTS: The barriers and facilitators were classified into 3 management themes: epilepsy-specific knowledge and information, treatment, and lifestyle. Within these themes, several important subthemes were identified. Two subthemes related to knowledge barriers emerged: children and caregivers’ limited understanding and retention of complex written and spoken information and variable training and confidence in seizure first-aid. In contrast, facilitators for introducing and encouraging access to epilepsy self-management concepts were participants’ eagerness to learn about this topic and a keen interest in using educational materials enriched with visual aids on a phone platform as an adjunct to in-person education. The second theme revealed various practical barriers to optimum treatment adherence, including mistrust of the health care system. In comparison, caregivers’ collaborative approach and innovative strategies were identified as facilitators for treatment adherence. Finally, the lifestyle management barriers included a lack of defined processes to adopt healthy behaviors and challenges with disclosing epilepsy. Facilitators of this theme were comprised of building a team around the child to foster wellbeing and making healthy habits a fun and joyful experience for children. DISCUSSION: Qualitative evidence in this study highlights caregivers’ mistrust in the health care system and the lack of community support. Culturally competent interventions may improve access to and quality and utilization of self-management programs in Black children and families while reducing disparities.

ObjectivesIndividuals with serious mental illnesses such as bipolar disorder (BD) are at an increased risk for poor medication adherence compared to the general population. Individuals with BD also have high rates of chronic comorbid medical conditions like hypertension (HTN), diabetes, and cardiovascular disease. Cognitive-behavioral therapies often integrate strategies to improve medication adherence by targeting medication attitudes and self-efficacy, but the pathway toward behavior change needs further investigation.MethodsThis 3-month prospective, single-arm cohort study tested an automated SMS intervention entitled Individualized Texting for Adherence Building- Cardiovascular (iTAB-CV) in 38 participants with BD and HTN. The Tablets Routine Questionnaire (TRQ) measures the percentage of BD and HTN non-adherence over the past week and the past month. Attitudinal and habit measures including the Brief Illness Perception Questionnaire (Brief IPQ), the Medication Adherence Self-Efficacy Scale-Revised (MASES-R), the Self-Report Habit Index (SRHI), the Beliefs about Medicines Questionnaire (BMQ), and the Attitudes toward Mood Stabilizers Questionnaire (AMSQ) were given for BD and HTN medications. Correlational analyses were run to determine the associations between BD and HTN attitudinal and habit indices. Additionally, longitudinal analyses were conducted to determine if attitudes changed over time as a function of a 2-month mobile-health intervention.ResultsIllness attitudes towards BD were worse than towards HTN at the start of the study. Attitudes toward BD and towards mood-stabilizing drugs as well as antihypertensives improved following a mHealth intervention aimed at improving adherence. Furthermore, self-efficacy and habit strength for both BD and HTN drugs were correlated and were responsive to the intervention, with most of the change occurring after the first month of the intervention and not requiring the addition of the explicit reminders.ConclusionParticipants who received iTAB-CV showed improved attitudes towards BD and mood-stabilizing medication, and had an improvement in self-efficacy and habit strength towards taking both BD and HTN medications. Increased attention to mechanisms of change in mHealth interventions for adherence may facilitate impact. It should be noted that the methodology of the study limits drawing causal conclusions and suggests the need for a randomized control trial.
