Abstract Hemispatial neglect is a common disabling condition following brain damage to the right hemisphere. Generally, it involves behavioral bias directed ipsilaterally to the damaged hemisphere ...and loss of spatial awareness for the contralesional side. In this syndrome, several clinical subtypes were identified. The objective of this article is to provide a nosological analysis of the recent data from the literature on the different subtypes of neglect (visual, auditory, somatosensory, motor, egocentric, allocentric and representational neglect), associated ipsilesional and contralesional productive manifestations and their anatomical lesion correlates. These different anatomical-clinical subtypes can be associated or dissociated. They reflect the heterogeneity of this unilateral neglect syndrome that cannot be approached or interpreted in a single manner. We propose that these subtypes result from different underlying deficits: exogenous attentional deficit (visual, auditory neglect); representational deficit (personal neglect, representational neglect, hyperschematia); shift of the egocentric reference frame (egocentric neglect); attentional deficit between objects and within objects (allocentric neglect), endogenous attentional deficit (representational neglect) and transsaccadic working memory or spatial remapping deficit (ipsilesional productive manifestations). Taking into account the different facets of the unilateral neglect syndrome should promote the development of more targeted cognitive rehabilitation protocols.

Spatial neglect (SN) impedes stroke rehabilitation progress, slows functional recovery, and increases caregiver stress and burden. The estimation of SN prevalence varies widely across studies.
We ...aimed to establish the prevalence of SN based on the injured cerebral hemisphere, recovery stage post-stroke, and diagnostic methodology.
All journal articles published up to February 27, 2019 from CINAHL, PsycINFO, PubMed and Web of Science were searched. We selected original research articles that described observational studies, included both individuals with left brain damage (LBD) and those with right brain damage (RBD) post-stroke, and reported specific diagnostic methods for SN. All authors reached consensus for the final selection of 41 articles. Time post-stroke, patient selection criteria, study setting, SN diagnostic methods were extracted.
A total of 6324 participants were included: 3411 (54%) with RBD and 2913 (46%) with LBD. Without considering time post-stroke or diagnostic methods, the occurrence rate of SN was 29% (38% after RBD and 18% after LBD). Using ecological assessments resulted in higher prevalence than using tests not directly related to daily life activities (53% vs. 24%). Using methods based on a single-cutoff criterion led to lower occurrence of SN than using multi-test methods (27% vs. 33%). The prevalence decreased from the acute to chronic stage post-stroke.
The estimated prevalence of SN after unilateral stroke is 30%. SN is more common after RBD than after LBD, but SN after LBD is still quite common. Using ecological assessments and multi-test methods to detect SN is preferred to using a single-cutoff criterion of a test that is not directly related to daily function. The decrease in SN prevalence over time is evident, but the exact prevalence in later stages cannot be estimated. More research is needed to better understand chronic SN.

Spatial neglect after right hemisphere stroke (RHS) was recently found to encompass lateropulsion, a deficit in body orientation with respect to gravity caused by altered brain processing of ...graviception. By analogy, we hypothesized that spatial neglect after RHS might encompass an altered representation of verticality. We also assumed a strong relation between body neglect and impaired postural vertical, both referring to the body. To tackle these issues, we performed contingency and correlation analyses between two domains of spatial neglect (body, extra‐body) and two modalities of verticality perception (postural, visual) in 77 individuals (median age = 67) with a first‐ever subacute RHS (1–3 months). All individuals with a transmodal (postural and visual) tilt in verticality perception (n = 26) had spatial neglect, but the reverse was not found. Correlation and multivariate analyses revealed that spatial neglect (and notably body neglect) was associated more with postural than visual vertical tilts. These findings indicate that after RHS, an impaired verticality representation results from a kind of graviceptive neglect, bearing first on somaesthetic graviception and second on vestibular graviception. They also suggest that the human brain uses not only a mosaic of 2D representations but also 3D maps involving a transmodal representation of verticality.
Spatial neglect after right hemisphere stroke (RHS) results in lateropulsion and might include altered representation of verticality. We assumed a relation between body neglect and impaired postural vertical. Spatial neglect was associated with postural and visual vertical tilts. RHS appears to impair verticality representation resulting from graviceptive neglect. The human brain seems to use a mosaic of 2D representations and 3D maps for transmodal representation of verticality.

Abstract Objective To determine whether child abuse and neglect predicts low levels of social support in middle adulthood and understand whether social support acts to mediate or moderate the ...relationship between childhood abuse and neglect and subsequent outcomes (anxiety, depression, and illicit drug use). Method Using data from a prospective cohort design study, children with documented histories of physical and sexual abuse and neglect (ages 0–11) during the years 1967 through 1971 and a matched control group were followed up and interviewed in adulthood. Social support was assessed at mean age 39.5, and anxiety, depression, and illicit drug use at mean age 41.2. Results Adjusting for age, sex, and race, individuals with documented histories of child abuse and neglect reported significantly lower levels of social support in adulthood total ( p < .001), appraisal ( p < .001), belonging ( p < .001), tangible ( p < .001), and self-esteem support ( p < .01) than controls. Adjusting for age, sex, race, and prior psychiatric diagnosis, social support mediated the relationship between child abuse and neglect and anxiety and depression in adulthood. Four gender by social support interactions and one three-way group (abuse/neglect versus control) × tangible social support × gender interaction moderated levels of anxiety and depression, particularly for males who were more strongly affected by high levels of social support. Conclusions Social support plays a significant role in mediating and moderating some long term consequences of childhood maltreatment. Efforts to better understand the timing and mechanisms involved in these relationships are needed to guide preventive interventions and treatment.

Childhood neglect, a prevalent form of child abuse, has significant short-term and long-term consequences on mental health.
This scoping review aimed to provide an overview of existing evidence on ...childhood neglect in relation to emotion regulation in adulthood.
Participants were not individually evaluated but we provided future directions for research based on the overview of studies.
A systematic search strategy was conducted, resulting in the analysis of 25 selected articles. We performed an inventory of existing evidence to identify knowledge gaps.
The review identified the need for future research to differentiate neglect from other forms of child abuse. Longitudinal studies tracking individuals from childhood to adulthood are recommended to understand developmental trajectories and continuity. Diverse samples, with various ages, genders, and (socio-economic) backgrounds, should be included for enhanced generalizability. Geographical representation should be expanded to capture cultural variations in the association between neglect and adult emotion regulation. Furthermore, investigating other psychopathologies beyond depression in relation to neglect and emotion regulation is suggested.
Overall, this scoping review highlights the limited knowledge regarding the link between childhood neglect and adult emotion regulation and provides valuable recommendations for advancing research in this field.

One evidence-based treatment for spatial neglect is prism adaptation (PA) treatment. PA after-effects, i.e., the implicit shifts in the arm reaching position toward the neglected side of space after ...prism removal, are considered fundamental to PA treatment effects. In the present study, the arm reaching position was shifted through a visuomotor misalignment procedure using immersive virtual reality (VR). To examine whether this procedure might have a beneficial impact on spatial neglect, we conducted a multi-baseline experiment in three individuals with chronic left-sided neglect post stroke. Improved spatial neglect was observed in all participants immediately after 5 sessions with two rounds in each. Two participants demonstrated lasting or continuous improvement two weeks later. Participants' pattern of brain lesions did not appear to clearly explain performance differences. The findings suggest that VR-induced visuomotor misalignment may improve spatial neglect immediately after a multi-session treatment course. The optimal number of sessions will be determined by future studies with a larger sample size, which may also elucidate the number of sessions sufficient for sustained improvement in most patients. Further investigations will identify the neural mechanisms underlying VR-induced visuomotor misalignment, which may or may not be identical to PA after-effects.

Abstract Attachment theory has been proposed as one explanation for the relationship between childhood maltreatment and problematic mental and physical health outcomes in adulthood. This study seeks ...to determine whether: (1) childhood physical abuse and neglect lead to different attachment styles in adulthood, (2) adult attachment styles predict subsequent mental and physical health outcomes, and (3) adult attachment styles mediate the relationship between childhood physical abuse and neglect and mental and physical health outcomes. Children with documented cases of physical abuse and neglect (ages 0–11) were matched with children without these histories and followed up in adulthood. Adult attachment style was assessed at mean age 39.5 and outcomes at 41.1. Separate path models examined mental and physical health outcomes. Individuals with histories of childhood neglect and physical abuse had higher levels of anxious attachment style in adulthood, whereas neglect predicted avoidant attachment as well. Both adult attachment styles (anxious and avoidant) predicted mental health outcomes (higher levels of anxiety and depression and lower levels of self-esteem), whereas only anxious adult attachment style predicted higher levels of allostatic load. Path analyses revealed that anxious attachment style in adulthood in part explained the relationship between childhood neglect and physical abuse to depression, anxiety, and self-esteem, but not the relationship to allostatic load. Childhood neglect and physical abuse have lasting effects on adult attachment styles and anxious and avoidant adult attachment styles contribute to understanding the negative mental health consequences of childhood neglect and physical abuse 30 years later in adulthood.

This article argues that it is still premature to start widespread screening for adverse childhood experiences (ACE) in health care settings until we have answers to several important questions: 1) ...what are the effective interventions and responses we need to have in place to offer to those with positive ACE screening, 2) what are the potential negative outcomes and costs to screening that need to be buffered in any effective screening regime, and 3) what exactly should we be screening for? The article makes suggestions for needed research activities.
