Generalized Periodic Discharges Associated With Catatonia and Delirium: A Case Series.

OBJECTIVE: Generalized periodic discharges are a repeated and generalized electroencephalography (EEG) pattern that can be seen in the context of altered mental status. This article describes a series of five individuals with generalized periodic discharges who demonstrated signs and symptoms of catatonia, a treatable neuropsychiatric condition. METHODS: Inpatients with a clinical diagnosis of catatonia, determined with the Bush-Francis Catatonia Rating Scale (BFCRS), and EEG recordings with generalized periodic discharges were analyzed in a retrospective case series. RESULTS: Five patients with catatonia and generalized periodic discharges on EEG were evaluated from among 106 patients with catatonia and contemporaneous EEG measurements. Four of these patients showed an improvement in catatonia severity when treated with benzodiazepines, with an average reduction of 6.75 points on the BFCRS. CONCLUSIONS: Among patients with generalized periodic discharges, catatonia should be considered, in the appropriate clinical context. Patients with generalized periodic discharges and catatonia may benefit from treatment with empiric trials of benzodiazepines.

A Link Between Inflammatory Mechanisms and Fibromyalgia.

Fibromyalgia (FM) is a condition characterized by chronic widespread pain, which has traditionally been considered psychogenic in nature due to lack of known underlying organic pathophysiology. In more recent years, inflammation of the nervous system has become increasingly recognized as a sign of neuropsychiatric conditions, and this association may enhance our knowledge of conditions such as FM. Emerging evidence has suggested inflammation, particularly neuroinflammation, as a potential contributor underlying the etiology of FM. Studies have searched for linked biomarkers with mixed results, though the literature is beginning to point to increased systemic levels of pro-inflammatory cytokines such as IL-6 and IL-8 in patients with FM relative to healthy controls. A multicenter imaging study has also reported results suggestive of microglial activation related to the presence of FM. Given the consistency in neuroinflammatory effects implicated in "sickness behavior" characteristic of chronic systemic inflammatory conditions such as cancer or rheumatic diseases, therein springs the hypothesis for a connection between FM and neuroinflammation as discussed in this chapter.

A retrospective data analysis of psychiatric cases in Hargeisa, Somaliland between 2019 and 2020.

Background: In Somaliland, an estimated one person in every two households suffers from psychiatric disorders. Despite this, access to mental health care is limited because of shortages in facilities, human resources, funding and stigma. Aim: To present the proportion of psychiatric disorders encountered in outpatient psychiatry clinics. Setting: The University if Hargeisa (UoH), Hargesisa, Somaliland. Methods: De-identified data on patients accessing psychiatric care from doctor trainees in the dual psychiatry-neurology residency program at UoH from January 2019 to June 2020 were included in the analysis. The Institutional Review Board from UoH approved data collection and analysis. The most common psychiatric diagnoses were summarised overall and by sex and age. Results: A total of 752 patients were included in the analysis. Most were male (54.7%), with an average age of 34.9 years. The most common psychiatric diagnoses were schizophrenia (28.0%), major depressive disorder (MDD) (14.3%) and bipolar disorder type 1 (BD1) (10.5%). When stratified by sex, patients with schizophrenia and BD1 were more likely to be male (73.5% and 53.3%, respectively), and those with MDD were more likely to be female (58.8%). Trauma- and stressor-related disorders accounted for 0.4% of cases, while 0.8% of patients presented with substance use disorders (alcohol and khat), which is an underestimate of the widespread use in Somaliland. Conclusion: Additional research using structured clinical interviews is needed to determine the epidemiology of psychiatric disorders and promote policies aiming to decrease neuropsychiatric mortality and morbidity. Contribution: This work presents the first data collection related to neuropsychiatric disorders in Somaliland.

Early-life trauma endophenotypes and brain circuit-gene expression relationships in functional neurological (conversion) disorder.

Functional neurological (conversion) disorder (FND) is a neuropsychiatric condition whereby individuals present with sensorimotor symptoms incompatible with other neurological disorders. Early-life maltreatment (ELM) is a risk factor for developing FND, yet few studies have investigated brain network-trauma relationships in this population. In this neuroimaging-gene expression study, we used two graph theory approaches to elucidate ELM subtype effects on resting-state functional connectivity architecture in 30 patients with motor FND. Twenty-one individuals with comparable depression, anxiety, and ELM scores were used as psychiatric controls. Thereafter, we compared trauma endophenotypes in FND with regional differences in transcriptional gene expression as measured by the Allen Human Brain Atlas (AHBA). In FND patients only, we found that early-life physical abuse severity, and to a lesser extent physical neglect, correlated with corticolimbic weighted-degree functional connectivity. Connectivity profiles influenced by physical abuse occurred in limbic (amygdalar-hippocampal), paralimbic (cingulo-insular and ventromedial prefrontal), and cognitive control (ventrolateral prefrontal) areas, as well as in sensorimotor and visual cortices. These findings held adjusting for individual differences in depression/anxiety, PTSD, and motor phenotypes. In FND, physical abuse also correlated with amygdala and insula coupling to motor cortices. In exploratory analyses, physical abuse correlated connectivity maps overlapped with the AHBA spatial expression of three gene clusters: (i) neuronal morphogenesis and synaptic transmission genes in limbic/paralimbic areas; (ii) locomotory behavior and neuronal generation genes in left-lateralized structures; and (iii) nervous system development and cell motility genes in right-lateralized structures. These circuit-specific architectural profiles related to individual differences in childhood physical abuse burden advance our understanding of the pathophysiology of FND.

Meditative and Mindfulness-Focused Interventions in Neurology: Principles, Science, and Patient Selection.

A growing body of research suggests that meditative- and mindfulness-focused interventions may improve neuropsychiatric symptoms that commonly occur in a range of neurological disorders. In this article, the principles of meditation and mindfulness are first defined, as well as briefly describing the neurobiological mechanisms implicated in these interventions. Thereafter, a range of meditative- and mindfulness-focused interventions are detailed, along with their supporting evidence to treat neuropsychiatric symptoms in neurological conditions (e.g., headache, movement disorders, chronic pain, etc.). Overall, these interventions warrant further investigation among individuals with neurological conditions. When recommending these interventions, health care professionals must consider a combination of structural (e.g., insurance reimbursement) and patient factors (e.g., ability to tolerate a group setting).

Developing a Dual Residency Program in Psychiatry and Neurology in an Area of Regional Conflict: The University of Hargeisa-Massachusetts General Hospital-Boston Medical Center Experience.

Noncommunicable diseases are the leading cause of worldwide death and disability and continue to increase in both developed and developing countries. There is a need to address and treat neuropsychiatric disorders in low-income countries, especially in the Horn of Africa. Capacity building by training local doctors and health care workers is a laborious endeavor, with challenges piling up along the way. Nevertheless, the rewards are great when brain specialists who are able to address the needs in their country and treat their fellow citizens receive the training needed to do so effectively. The present article describes a coordinated administrative, educational, and clinical effort to develop and implement a dual residency program in psychiatry and neurology at the University of Hargeisa in Somaliland. The authors highlight the foundations of the program and the challenges faced during its development and implementation in an area of regional conflict. The program provides evidence that this aim is achievable and serves as a model for others seeking to replicate it in other low- and middle-income countries.

Post-Acute Sequelae of SARS-CoV-2 Infection: A Descriptive Clinical Study.

OBJECTIVE: The investigators aimed to describe the clinical experience of a single center reporting on neuropsychiatric findings among patients experiencing persistent symptoms as part of post-acute sequelae of SARS-CoV-2 (PASC) infection. METHODS: Data were collected retrospectively (between February 2020 and May 2021) from a cohort (N=100) within a COVID-19 survivors study of patients with persistent symptoms enrolled after a short inpatient stay or who had been outpatients never hospitalized. Patients without confirmatory positive PCR or antibody diagnostic test results were grouped separately as presumptive cases (N=13). RESULTS: Of the 87 patients with confirmed SARS-CoV-2, 63 (72.4%) were female, and 65 (74.7%) were White. The mean age was 49.2 years (SD=14.9). The most prevalent symptoms after COVID-19 infection were fatigue, "brain fog," headache, anxiety, and sleep issues. Attention and executive function were frequently impaired. The mean Montreal Cognitive Assessment score was 26.0 (SD=2.8). Concentration and attention as well as memory issues were both significantly correlated with the complaint of brain fog. CONCLUSIONS: These preliminary findings suggest that post-acute sequelae of SARS-CoV-2 vary in frequency and duration with relation to premorbid history and that these conditions affect functional domains and patients' ability to return to work. Longitudinal research with larger cohorts is needed to characterize PASC and to optimize care, especially for vulnerable populations.

Effects of Emotional Expressiveness of a Female Digital Human on Loneliness, Stress, Perceived Support, and Closeness Across Genders: Randomized Controlled Trial.

BACKGROUND: Loneliness is a growing public health problem that has been exacerbated in vulnerable groups during the COVID-19 pandemic. Social support interventions have been shown to reduce loneliness, including when delivered through technology. Digital humans are a new type of computer agent that show promise as supportive peers in health care. For digital humans to be effective and engaging support persons, it is important that they develop closeness with people. Closeness can be increased by emotional expressiveness, particularly in female relationships. However, it is unknown whether emotional expressiveness improves relationships with digital humans and affects physiological responses. OBJECTIVE: The aim of this study is to investigate whether emotional expression by a digital human can affect psychological and physiological outcomes and whether the effects are moderated by the user's gender. METHODS: A community sample of 198 adults (101 women, 95 men, and 2 gender-diverse individuals) was block-randomized by gender to complete a 15-minute self-disclosure conversation with a female digital human in 1 of 6 conditions. In these conditions, the digital human varied in modality richness and emotional expression on the face and in the voice (emotional, neutral, or no face; emotional or neutral voice). Perceived loneliness, closeness, social support, caring perceptions, and stress were measured after each interaction. Heart rate, skin temperature, and electrodermal activity were assessed during each interaction. 3-way factorial analyses of variance with post hoc tests were conducted. RESULTS: Emotional expression in the voice was associated with greater perceptions of caring and physiological arousal during the interaction, and unexpectedly, with lower feelings of support. User gender moderated the effect of emotional expressiveness on several outcomes. For women, an emotional voice was associated with increased closeness, social support, and caring perceptions, whereas for men, a neutral voice increased these outcomes. For women, interacting with a neutral face was associated with lower loneliness and subjective stress compared with no face. Interacting with no face (ie, a voice-only black screen) resulted in lower loneliness and subjective stress for men, compared with a neutral or emotional face. No significant results were found for heart rate or skin temperature. However, average electrodermal activity was significantly higher for men while interacting with an emotional voice. CONCLUSIONS: Emotional expressiveness in a female digital human has different effects on loneliness, social, and physiological outcomes for men and women. The results inform the design of digital human support persons and have theoretical implications. Further research is needed to evaluate how more pronounced emotional facial expressions in a digital human might affect the results.

Qigong for the Prevention, Treatment, and Rehabilitation of COVID-19 Infection in Older Adults.

The elderly are at high risk of contracting respiratory infectious diseases, including COVID-19 infection. The recent pandemic has the potential to cause significant physical and mental damage in older adults. Similarly to other mind-body exercises in Traditional Chinese medicine, Qigong features regulation of breath rhythm and pattern, body movement and posture, and meditation. Given these traits, Qigong has the potential to play a role in the prevention, treatment, and rehabilitation of respiratory infections, such as COVID-19. Potential mechanisms of action include stress reduction, emotion regulation, strengthening of respiratory muscles, reduction of inflammation, and enhanced immune function. Three forms of Qigong; abdominal breathing, Ba Duan Jin and Liu Zi Jue, all of which are gentle, smooth, and simple for the elderly to practice, are recommended in this context.

Fearful Attachment Linked to Childhood Abuse, Alexithymia, and Depression in Motor Functional Neurological Disorders.

Insecure attachment is a predisposing risk factor for the development of functional neurological disorder (FND). There is limited research investigating connections between attachment styles, other predisposing vulnerabilities, and symptom severity in patients with motor FND. By using a within-group design with prospective data collection, the authors performed univariate tests followed by multivariate linear regressions to investigate neuropsychiatric factors associated with four attachment styles (secure, fearful, preoccupied, and dismissing) among 56 patients with motor FND (mean age=40.2 years [SD=13.0]; women, N=41; men, N=15). In univariate analyses, fearful attachment style was associated with self-reported adverse life event burden, alexithymia, dissociation, depression, anxiety, impaired stress coping skills, functional neurologic symptom severity, and marital status. In a multivariate stepwise linear regression analysis, childhood abuse, alexithymia, depression, and not being married independently predicted fearful attachment. In a post hoc analysis, childhood sexual and emotional abuse were each independently associated with fearful attachment tendencies. There were no independent predictors of secure, preoccupied, or dismissing attachment styles in this study population. Future studies with larger cohorts are needed to investigate nuanced relationships among predisposing vulnerabilities for the development of FND, as well as potential links between risk factors, functional neurologic symptom severity, and clinical outcomes.

Secure Attachment and Depression Predict 6-Month Outcome in Motor Functional Neurological Disorders: A Prospective Pilot Study.

BACKGROUND: The relationships between baseline neuropsychiatric factors and clinical outcome in patients with functional neurological disorder (FND)/conversion disorder remain poorly understood. OBJECTIVE: This prospective, naturalistic pilot study investigated links between predisposing vulnerabilities (risk factors) and clinical outcome in patients with motor FND engaged in usual care within a subspecialty FND clinic. METHODS: Thirty-four patients with motor FND were enrolled and completed baseline and 6-month follow-up psychometric questionnaires. Univariate screening tests followed by multivariate linear regression analyses were used to investigate neuropsychiatric predictors of 6-month clinical outcome in patients with motor FND. RESULTS: In univariate analyses, baseline secure attachment traits and depression as measured by the Relationship Scales Questionnaire and Beck Depression Inventory-II positively correlated with improved Patient Health Questionnaire-15 scores. In a multivariate linear regression analysis adjusting for the interval time between baseline and follow-up data collection, baseline secure attachment and depression scores independently predicted improvements in Patient Health Questionnaire-15 scores. In additional analyses, patients with a diagnosis of psychogenic nonepileptic seizures compared to individuals with other motor FND subtypes showed a trend toward worse 6-month physical health outcomes as measured by the Short Form Health Survey-36. CONCLUSION: Future large-scale, multi-site longitudinal studies are needed to comprehensively investigate neuropsychiatric predictors of clinical outcome in patients with motor FND, including functional weakness, functional movement disorders, and psychogenic nonepileptic seizures.

Systematic review of burnout among healthcare providers in sub-Saharan Africa.

BACKGROUND: Burnout is characterized by physical and emotional exhaustion from long-term exposure to emotionally demanding work. Burnout affects interpersonal skills, job performance, career satisfaction, and psychological health. However, little is known about the burden of burnout among healthcare providers in sub-Saharan Africa. METHODS: Relevant articles were identified through a systematic review of PubMed, Web of Science (Thomson Reuters), and PsycINFO (EBSCO). Studies were selected for inclusion if they examined a quantitative measure of burnout among healthcare providers in sub-Saharan Africa. RESULTS: A total of 65 articles met our inclusion criteria for this systematic review. Previous studies have examined burnout in sub-Saharan Africa among physicians (N = 12 articles), nurses (N = 26), combined populations of healthcare providers (N = 18), midwives (N = 2), and medical or nursing students (N = 7). The majority of studies assessed burnout using the Maslach Burnout Inventory. The highest levels of burnout were reported among nurses, although all healthcare providers showed high burnout. Burnout among healthcare providers is associated with their work environments, interpersonal and professional conflicts, emotional distress, and low social support. CONCLUSIONS: Available studies on this topic are limited by several methodological challenges. More rigorously designed epidemiologic studies of burnout among healthcare providers are warranted. Health infrastructure improvements will eventually be essential, though difficult to achieve, in under-resourced settings. Programs aimed at raising awareness and coping with burnout symptoms through stress management and resilience enhancement trainings are also needed.

Reducing Patient Loneliness With Artificial Agents: Design Insights From Evolutionary Neuropsychiatry.

Loneliness is a growing public health issue that substantially increases the risk of morbidity and mortality. Artificial agents, such as robots, embodied conversational agents, and chatbots, present an innovation in care delivery and have been shown to reduce patient loneliness by providing social support. However, similar to doctor and patient relationships, the quality of a patient's relationship with an artificial agent can impact support effectiveness as well as care engagement. Incorporating mammalian attachment-building behavior in neural network processing as part of an agent's capabilities may improve relationship quality and engagement between patients and artificial agents. We encourage developers of artificial agents intended to relieve patient loneliness to incorporate design insights from evolutionary neuropsychiatry.

Catatonia in patients with anti-NMDA receptor encephalitis.

AIM: There is a lack of studies related to the frequency, phenomenology, and associated features of catatonic syndrome in patients with anti-NMDA receptor encephalitis (ANMDARE). This study aimed to measure the frequency of catatonia in this condition and to delineate its particular symptoms. METHODS: A prospective study was done with all inpatients who fulfilled the criteria of definite ANMDARE admitted to the National Institute of Neurology and Neurosurgery of Mexico from January 2014 to September 2018. The Bush-Francis Catatonia Rating Scale and Braünig Catatonia Rating Scale were administered at admission. RESULTS: Fifty-eight patients were included and catatonia was diagnosed in 41 of these patients (70.6%). Immobility, staring, mutism, and posturing were the most frequent catatonic signs. Catatonia was associated with delirium, hallucinations, psychomotor agitation, generalized electroencephalography dysfunction, and previous use of antipsychotics. Mortality was present in 10% of the total sample; it was associated with status epilepticus, and was less frequent in the catatonia group. After immunotherapy, all cases showed a complete recovery from catatonic signs. CONCLUSION: This systematic assessment of catatonic syndrome shows that it is a frequent feature in patients with ANMDARE as part of a clinical pattern that includes delirium, psychomotor agitation, and hallucinations. The lack of recognition of this pattern may be a source of diagnostic and therapeutic errors, as most physicians associate catatonia with schizophrenia and affective disorders.

Opioid and Opiate Immunoregulatory Processes.

The discovery of the ability of the nervous system to communicate through "public" circuits with other systems of the body is attributed to Ernst and Berta Scharrer, who described the neurosecretory process in 1928. Indeed, the immune system has been identified as another important neuroendocrine target tissue. Opioid peptides are involved in this communication (i.e., neuroimmune) and with that of autoimmunoregulation (communication between immunocytes). The significance of opioid neuropeptide involvement with the immune system is ascertained from the presence of novel δ, µ., and κ receptors on inflammatory cells that result in modulation of cellular activity after activation, as well as the presence of specific enzymatic degradation and regulation processes. In contrast to the relatively uniform antinociceptive action of opiate and opioid signal molecules in neural tissues, the presence of naturally occurring morphine in plasma and a novel µ3 opiate-specific receptor on inflammatory cells adds to the growing knowledge that opioid and opiate signal molecules may have antagonistic actions in select tissues. In examining various disorders (e.g., human immunodeficiency virus, substance abuse, parasitism, and the diffuse inflammatory response associated with surgery) evidence has also been found for the involvement of opiate/opioid signaling in prominent mechanisms. In addition, the presence of similar mechanisms in man and organisms 500 million years divergent in evolution bespeaks the importance of this family of signal molecules. The present review provides an overview of recent advances in the field of opiate and opioid immunoregulatory processes and speculates as to their significance in diverse biological systems.

Adverse obstetric and neonatal outcomes complicated by psychosis among pregnant women in the United States.

BACKGROUND: Adverse obstetric and neonatal outcomes among women with psychosis, particularly affective psychosis, has rarely been studied at the population level. We aimed to assess the risk of adverse obstetric and neonatal outcomes among women with psychosis (schizophrenia, affective psychosis, and other psychoses). METHODS: From the 2007 - 2012 National (Nationwide) Inpatient Sample, 23,507,597 delivery hospitalizations were identified. From the same hospitalization, International Classification of Diseases diagnosis codes were used to identify maternal psychosis and outcomes. Adjusted odds ratios (aOR) and 95% confidence intervals (CI) were obtained using logistic regression. RESULTS: The prevalence of psychosis at delivery was 698.76 per 100,000 hospitalizations. After adjusting for sociodemographic characteristics, smoking, alcohol/substance abuse, and pregnancy-related hypertension, women with psychosis were at a heightened risk for cesarean delivery (aOR = 1.26; 95% CI: 1.23 - 1.29), induced labor (aOR = 1.05; 95% CI: 1.02 - 1.09), antepartum hemorrhage (aOR = 1.22; 95% CI: 1.14 - 1.31), placental abruption (aOR = 1.22; 95% CI: 1.13 - 1.32), postpartum hemorrhage (aOR = 1.18; 95% CI: 1.10 - 1.27), premature delivery (aOR = 1.40; 95% CI: 1.36 - 1.46), stillbirth (aOR = 1.37; 95% CI: 1.23 - 1.53), premature rupture of membranes (aOR = 1.22; 95% CI: 1.15 - 1.29), fetal abnormalities (aOR = 1.49; 95% CI: 1.38 - 1.61), poor fetal growth (aOR = 1.26; 95% CI: 1.19 - 1.34), and fetal distress (aOR = 1.14; 95% CI: 1.10 - 1.18). Maternal death during hospitalizations (aOR = 1.00; 95% CI: 0.30 - 3.31) and excessive fetal growth (aOR = 1.06; 95% CI: 0.98 - 1.14) were not statistically significantly associated with psychosis. CONCLUSIONS: Pregnant women with psychosis have elevated risk of several adverse obstetric and neonatal outcomes. Efforts to identify and manage pregnancies complicated by psychosis may contribute to improved outcomes.

Military and Veteran Caregivers' Perspectives of Stressors and a Mind-Body Program.

There are over one million post-9/11 military caregivers in the United States who face a variety of stressors inherent to caring for an incapacitated loved one. Mind-body interventions, such as the Stress Management and Resilience Training Relaxation Response Resiliency Program (SMART-3RP), have been shown to reduce stress and improve overall health and functioning. The present qualitative study aims to explore stressors experienced by military caregivers in their caregiving role and to assess attitudes towards the virtual delivery of the SMART-3RP. We conducted two focus groups with a total of 13 caregivers [M (SD) age = 41.25 (11.49); 92% female], and participants subsequently completed a survey on their caregiving experiences. Focus groups were conducted remotely via Google Hangouts by two doctoral-level clinicians, transcribed verbatim, and coded using inductive thematic analysis. Themes related to stressors of caregiving included: logistical stressors faced by caregivers, demands of the caregiving role, concerns about children, worries about the future, exacerbation of the caregiver's physical/mental health concerns, social dynamics, sacrifices made for their veteran in the caregiving role, and relationship dynamics between the veteran and caregiver. Military caregivers found the SMART-3RP logical and felt as though it could be helpful to them. Caregivers expressed interest in a brief, virtual version of the SMART-3RP. Using the findings from the current study, we are adapting the SMART-3RP to be administered virtually as a podcast-based intervention.
