Objectives

Limited information exists about violent deaths among people experiencing homelessness (PEH) across the United States. Using data from a national reporting system, we describe characteristics of suicides, homicides, and other deaths classified as violent among PEH in the United States.

Methods

We obtained data on demographic characteristics, mechanisms of injury, and circumstances surrounding violent deaths from January 1, 2016, through December 31, 2018, in 31 states from the National Violent Death Reporting System.

Results

Of 122 113 violent deaths in 31 states during 2016-2018, 1757 (1.4%) occurred among PEH and 3952 (3.2%) occurred among people for whom homelessness status was unknown or missing. Of all violent deaths among PEH, 878 were suicides (1.1% of all suicides), 458 were homicides (1.6% of all homicides), 352 were of undetermined intent (2.8% of all deaths of undetermined intent), and 59 were the result of legal interventions (3.8% of all deaths due to legal interventions). Hanging/suffocation/strangulation was the most common mechanism of suicide among PEH (44.4%), followed by deaths due to firearms (21.6%). Firearms were the most common mechanism of homicide deaths among PEH (48.0%). Black PEH were more likely to die by homicide than by suicide, and White PEH were more likely to die by suicide than by homicide. Among the 843 suicide victims for whom additional information was known, 345 (40.9%) had a history of suicidal thoughts or plans, 245 (29.1%) had disclosed intent to die by suicide, and 183 (21.7%) were receiving treatment for a mental health condition.

Conclusions

Efforts to reduce mortality and improve health outcomes among PEH should consider the high rates of violent deaths in this population.

An aging prison population means more people who are incarcerated will experience dementia and related symptoms (eg, cognitive impairment, behavioral outbursts, poor impulse control). This article canvasses clinical and ethical complexities of caring for people with dementia who are incarcerated and examines how to adapt carceral settings to better meet the needs of people with dementia. This article also recommends policy reforms, such as treatment-based diversion programs, early parole, and medical release, to decrease numbers of individuals with dementia who are incarcerated whenever possible.

Incarceration can disrupt healthy sleep, and insomnia is associated with psychiatric symptoms and poor general medical health among incarcerated people. In recent years, considerable litigation has arisen over sleep deprivation in U.S. jails and prisons. This column examines litigation over conditions of incarceration, such as noise, inadequate bedding, constant illumination, medication restrictions, and early wake-up times, that may affect sleep duration and quality. The potential adverse effects of inadequate sleep on incarcerated individuals, as well as associated litigation, suggest the need for policies that reduce unnecessary sleep deprivation and promote healthy sleep in correctional facilities.

Purpose

Aging and mental illness both represent significant public health challenges for incarcerated people in the USA. The COVID-19 pandemic has further highlighted the vulnerabilities of incarcerated people because of the risks of infectious disease transmission in correctional facilities. Focusing on older adults with mental illness, this paper aims to examine efforts to decarcerate US correctional facilities during the COVID-19 pandemic and whether these approaches may lead to sustainable reforms beyond the pandemic.

Design/methodology/approach

A narrative literature review was conducted using numerous online resources, including PubMed, Google Scholar and LexisNexis. Search terms used included "decarceration pandemic," "COVID-19 decarceration," "aging mental illness decarceration," "jails prisons decarceration," "early release COVID-19" and "correctional decarceration pandemic," among others. Given the rapidly changing nature of the COVID-19 pandemic, this narrative literature review included content from not only scholarly articles and federal and state government publications but also relevant media articles and policy-related reports. The authors reviewed these sources collaboratively to synthesize a review of existing evidence and opinions on these topics and generate conclusions and policy recommendations moving forward.

Findings

To mitigate the risks of COVID-19, policymakers have pursued various decarceration strategies across the USA. Some efforts have focused on reducing inflow into correctional systems, including advising police to reduce numbers of arrests and limiting use of pretrial detention. Other policies have sought to increase outflow from correctional systems, such as facilitating early release of people convicted of nonviolent offenses or those nearing the end of their sentences. Given the well-known risks of COVID-19 among older individuals, age was commonly cited as a reason for diverting or expediting release of people from incarceration. In contrast, despite their vulnerability to complications from COVID-19, people with serious mental illness (SMI), particularly those with acute treatment needs, may have been less likely in some instances to be diverted or released early from incarceration.

Originality/value

Although much has been written about decarceration during the COVID-19 pandemic, little attention has been paid to the relevance of these efforts for older adults with mental illness. This paper synthesizes existing proposals and evidence while drawing attention to the public health implications of aging and SMI in US correctional settings and explores opportunities for decarceration of older adults with SMI beyond the COVID-19 pandemic.

Aging into later life is often accompanied by social disconnection, anxiety, and sadness. Negative emotions are self-focused states with detrimental effects on aging and longevity. Awe-a positive emotion elicited when in the presence of vast things not immediately understood-reduces self-focus, promotes social connection, and fosters prosocial actions by encouraging a small self. We investigated the emotional benefits of a novel awe walk intervention in healthy older adults. Sixty participants took weekly 15-min outdoor walks for 8 weeks; participants were randomly assigned to an awe walk group, which oriented them to experience awe during their walks, or to a control walk group. Participants took photographs of themselves during each walk and rated their emotional experience. Each day, they reported on their daily emotional experience outside of the walk context. Participants also completed pre- and postintervention measures of anxiety, depression, and life satisfaction. Compared with participants who took control walks, those who took awe walks experienced greater awe during their walks and exhibited an increasingly small self in their photographs over time. They reported greater joy and prosocial positive emotions during their walks and displayed increasing smile intensity over the study. Outside of the walk context, participants who took awe walks reported greater increases in daily prosocial positive emotions and greater decreases in daily distress over time. Postintervention anxiety, depression, and life satisfaction did not change from baseline in either group. These results suggest cultivating awe enhances positive emotions that foster social connection and diminishes negative emotions that hasten decline.

Individuals with high emotional granularity make fine-grained distinctions between their emotional experiences. To have greater emotional granularity, one must acquire rich conceptual knowledge of emotions and use this knowledge in a controlled and nuanced way. In the brain, the neural correlates of emotional granularity are not well understood. While the anterior temporal lobes, angular gyri, and connected systems represent conceptual knowledge of emotions, inhibitory networks with hubs in the inferior frontal cortex (i.e., posterior inferior frontal gyrus, lateral orbitofrontal cortex, and dorsal anterior insula) guide the selection of this knowledge during emotions. We investigated the structural neuroanatomical correlates of emotional granularity in 58 healthy, older adults (ages 62-84 years), who have had a lifetime to accrue and deploy their conceptual knowledge of emotions. Participants reported on their daily experience of 13 emotions for 8 weeks and underwent structural magnetic resonance imaging. We computed intraclass correlation coefficients across daily emotional experience surveys (45 surveys on average per participant) to quantify each participant's overall emotional granularity. Surface-based morphometry analyses revealed higher overall emotional granularity related to greater cortical thickness in inferior frontal cortex (p_FWE < 0.05) in bilateral clusters in the lateral orbitofrontal cortex and extending into the left dorsal anterior insula. Overall emotional granularity was not associated with cortical thickness in the anterior temporal lobes or angular gyri. These findings suggest individual differences in emotional granularity relate to variability in the structural neuroanatomy of the inferior frontal cortex, an area that supports the controlled selection of conceptual knowledge during emotional experiences.

Reading difficulties are the hallmark feature of dyslexia, but less is known about other areas of functioning. Previously, we found children with dyslexia exhibited heightened emotional reactivity, which correlated with better social skills. Whether emotional differences in dyslexia extend to the parasympathetic nervous system-an autonomic branch critical for attention, social engagement, and empathy-is unknown. Here, we measured autonomic nervous system activity in 24 children with dyslexia and 24 children without dyslexia, aged 7 - 12, at rest and during a film-based empathy task. At rest, children with dyslexia had higher respiratory sinus arrhythmia (RSA) than those without dyslexia. Cardiac deceleration during the empathy task was greater in dyslexia and correlated with higher resting RSA across the sample. Children with dyslexia produced more facial expressions of concentration during film-viewing, suggesting greater engagement. These results suggest elevated resting parasympathetic activity and accentuated autonomic and behavioral responding to others' emotions in dyslexia.

Dyslexia is a neurodevelopmental disorder mainly defined by reading difficulties. During reading, individuals with dyslexia exhibit hypoactivity in left-lateralized language systems. Lower activity in one brain circuit can be accompanied by greater activity in another, and, here, we examined whether right-hemisphere-based emotional reactivity may be elevated in dyslexia. We measured emotional reactivity (i.e., facial behavior, physiological activity, and subjective experience) in 54 children ages 7-12 with (n = 32) and without (n = 22) dyslexia while they viewed emotion-inducing film clips. Participants also underwent task-free functional magnetic resonance imaging. Parents of children with dyslexia completed the Behavior Assessment System for Children, which assesses real-world behavior. During film viewing, children with dyslexia exhibited significantly greater reactivity in emotional facial behavior, skin conductance level, and respiration rate than those without dyslexia. Across the sample, greater emotional facial behavior correlated with stronger connectivity between right ventral anterior insula and right pregenual anterior cingulate cortex (p_FWE<.05), key salience network hubs. In children with dyslexia, greater emotional facial behavior related to better real-world social skills and higher anxiety and depression. Our findings suggest there is heightened visceromotor emotional reactivity in dyslexia, which may lead to interpersonal strengths as well as affective vulnerabilities.

In semantic dementia (SD), asymmetric degeneration of the anterior temporal lobes is associated with loss of semantic knowledge and alterations in socioemotional behavior. There are two clinical variants of SD: semantic variant primary progressive aphasia (svPPA), which is characterized by predominant atrophy in the anterior temporal lobe and insula in the left hemisphere, and semantic behavioral variant frontotemporal dementia (sbvFTD), which is characterized by predominant atrophy in those structures in the right hemisphere. Previous studies of behavioral variant frontotemporal dementia, an associated clinical syndrome that targets the frontal lobes and anterior insula, have found impairments in baseline autonomic nervous system activity that correlate with left-lateralized frontotemporal atrophy patterns and disruptions in socioemotional functioning. Here, we evaluated whether there are similar impairments in resting autonomic nervous system activity in SD that also reflect left-lateralized atrophy and relate to diminished affiliative behavior. A total of 82 participants including 33 people with SD (20 svPPA and 13 sbvFTD) and 49 healthy older controls completed a laboratory-based assessment of respiratory sinus arrhythmia (RSA; a parasympathetic measure) and skin conductance level (SCL; a sympathetic measure) during a two-minute resting baseline period. Participants also underwent structural magnetic resonance imaging, and informants rated their current affiliative behavior on the Interpersonal Adjective Scale. Results indicated that baseline RSA and SCL were lower in SD than in healthy controls, with significant impairments present in both svPPA and sbvFTD. Voxel-based morphometry analyses revealed left-greater-than-right atrophy related to diminished parasympathetic and sympathetic outflow in SD. While left-lateralized atrophy in the mid-to-posterior insula correlated with lower RSA, left-lateralized atrophy in the ventral anterior insula correlated with lower SCL. In SD, lower baseline RSA, but not lower SCL, was associated with lower gregariousness/extraversion. Neither autonomic measure related to warmth/agreeableness, however. Through the assessment of baseline autonomic nervous system physiology, the present study contributes to expanding conceptualizations of the biological basis of socioemotional alterations in svPPA and sbvFTD.

Diminished basal parasympathetic nervous system activity is a feature of frontotemporal dementia that relates to left frontoinsula dysfunction and empathy impairment. Individuals with a pathogenic expansion of the hexanucleotide repeat in chromosome 9 open reading frame 72 (C9orf72), the most common genetic cause of frontotemporal dementia and amyotrophic lateral sclerosis, provide a unique opportunity to examine whether parasympathetic activity is disrupted in genetic forms of frontotemporal dementia and to investigate when parasympathetic deficits manifest in the pathophysiological cascade. We measured baseline respiratory sinus arrhythmia, a parasympathetic measure of heart rate variability, over two minutes in a sample of 102 participants that included 19 asymptomatic expansion carriers (C9⁺ asymp), 14 expansion carriers with mild cognitive impairment (C9⁺ MCI), 16 symptomatic expansion carriers with frontotemporal dementia (C9⁺ FTD), and 53 expansion-negative healthy controls (C9^- HC) who also underwent structural magnetic resonance imaging. In follow-up analyses, we compared baseline respiratory sinus arrhythmia in the C9⁺ FTD group with an independent age-, sex-, and clinical severity-matched group of 26 people with sporadic behavioral variant frontotemporal dementia. The Frontotemporal Lobar Degeneration-modified Clinical Dementia Rating-Sum of Boxes score was used to quantify behavioral symptom severity, and informant ratings on the Interpersonal Reactivity Index provided measures of participants' current emotional (empathic concern) and cognitive (perspective-taking) empathy. Results indicated that the C9⁺ FTD group had lower baseline respiratory sinus arrhythmia than the C9⁺ MCI, C9⁺ asymp, and C9^- HC groups, a deficit that was comparable to that of sporadic behavioral variant frontotemporal dementia. Linear regression analyses indicated that lower baseline respiratory sinus arrhythmia was associated with worse behavioral symptom severity and lower empathic concern and perspective-taking across the C9orf72 expansion carrier clinical spectrum. Whole-brain voxel-based morphometry analyses in participants with C9orf72 pathogenic expansions found that lower baseline respiratory sinus arrhythmia correlated with smaller gray matter volume in the left frontoinsula and bilateral thalamus, key structures that support parasympathetic function, and in the bilateral parietal lobes, occipital lobes, and cerebellum, regions that are also vulnerable in individuals with C9orf72 expansions. This study provides novel evidence that basal parasympathetic functioning is diminished in FTD due to C9orf72 expansions and suggests that baseline respiratory sinus arrhythmia may be a potential non-invasive biomarker that is sensitive to behavioral symptoms in the early stages of disease.
