Cerebral palsy in Canadian Indigenous children

Cerebral Palsy Heterogeneity: Clinical Characteristics and Diagnostic Significance from a Large-Sample Analysis

INTRODUCTION

Cerebral palsy (CP) is a nonprogressive movement disorder resulting from a prenatal or perinatal brain injury that benefits from early diagnosis and intervention. The timing of early CP diagnosis remains controversial, necessitating analysis of clinical features in a substantial cohort.

METHODS

We retrospectively reviewed medical records from a university hospital, focusing on children aged ≥24 months or followed up for ≥24 months and adhering to the International Classification of Diseases-10 for diagnosis and subtyping.

RESULTS

Among the 2012 confirmed CP cases, 68.84% were male and 51.44% had spastic diplegia. Based on the Gross Motor Function Classification System (GMFCS), 62.38% were in levels I and II and 19.88% were in levels IV and V. Hemiplegic and diplegic subtypes predominantly fell into levels I and II, while quadriplegic and mixed types were mainly levels IV and V. White matter injuries appeared in 46.58% of cranial MRI findings, while maldevelopment was rare (7.05%). Intellectual disability co-occurred in 43.44% of the CP cases, with hemiplegia having the lowest co-occurrence (20.28%, 58/286) and mixed types having the highest co-occurrence (73.85%, 48/65). Additionally, 51.67% (697/1,349) of the children with CP aged ≥48 months had comorbidities.

CONCLUSIONS

This study underscores white matter injury as the primary CP pathology and identifies intellectual disability as a common comorbidity. Although CP can be identified in infants under 1 year old, precision in diagnosis improves with development. These insights inform early detection and tailored interventions, emphasizing their crucial role in CP management.

Social determinants of health for children with cerebral palsy and their families

Social determinants of health (SDH) influence health and social outcomes in positive and negative ways. Understanding the impact of SDH on children with cerebral palsy (CP) is essential to improve health equity, optimize health outcomes, and support children with CP and their families to thrive in society. In this narrative review, we summarize the landscape of SDH impacting children with CP and their families worldwide. In high-income countries, children from poorer neighbourhoods are more likely to have severe comorbidities, present with spastic bilateral CP, and report lower frequency of participation in community activities. In low- and middle-income countries, socioeconomic disadvantage is associated with increased risk of malnutrition, living in poorer housing conditions, not having access to proper sanitation, and living below the poverty line. Low maternal education is associated with increased likelihood of the child with CP experiencing increased severity of gross motor and bimanual functioning challenges, and poorer academic performance. Lower parental education is also associated with reduced child autonomy. On the other hand, higher parental income is a protective factor, associated with greater diversity of participation in day-to-day activities. A better physical environment and better social support are associated with higher participation in daily activities. Clinicians, researchers, and the community should be aware of these key challenges and opportunities. Then adopt a range of approaches that target adverse SDH/social needs and foster positive SDH in the clinical setting. WHAT THIS PAPER ADDS: Understanding how social determinants of health influence health and social outcomes is a critical step towards improving health equity and outcomes. Approaches are required that target the impact of adverse SDH on access to health care for children with cerebral palsy and that work towards ensuring equity of access for all.

Neurotrauma in Indigenous Populations of Canada-Challenges and Opportunities at a Global Level: A Scoping Review

BACKGROUND

Neurotrauma accounts for over 24,000 hospitalizations annually in Canada and has a significant impact in many developed countries. Among those affected, indigenous peoples are disproportionately impacted. The present scoping review explores the factors contributing to neurotrauma in indigenous populations and potential strategies to address this health care issue at a global level.

METHODS

A search was performed in Medline (1974-2021) and Embase (1946-2021) to identify studies pertaining to neurotrauma in indigenous populations of Canada. Search terms included 'Aboriginal', 'First Nation', 'Indigenous', 'traumatic brain injury', and 'traumatic spine injury'. Thematic analysis was then used to synthesize the information collected. A gray literature search was also performed.

RESULTS

The original literature search yielded 1609 articles, with 17 selected for the scoping review. Through thematic analysis, the factors contributing to neurotrauma burden in indigenous populations of Canada were summarized into 3 themes: inadequate resources available, social problems in indigenous communities, and challenges within the health care system. The potential strategies to address neurotrauma were also summarized into 3 themes: system-level changes to Canadian health care, community-based initiatives, and culturally appropriate solutions. The gray literature search revealed a lack of government reports on the topic and notable advocacy work from community organizations.

CONCLUSIONS

Systems-level interventions guided by indigenous community members will help to address the disparities that indigenous peoples face in the care and rehabilitation of neurotrauma. This study will inform further research of culturally appropriate approaches to reduce neurotrauma among indigenous peoples at a global level.
