Spinal Cord: Cross-sectional Anatomy

Spinal Cord: Cross-sectional Anatomy

The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

Central to the gray matter is...

Summary

This study describes individuals with cerebral palsy (CP) in Brazil, finding that despite advances, most have severe motor impairments. Supporting registries in low- and middle-income countries is crucial for family-centered care.

Background:

Cerebral palsy (CP) is a complex neurological disorder affecting movement and posture.
Understanding the demographics and clinical characteristics of individuals with CP is essential for effective healthcare planning.

Purpose of the Study:

To characterize individuals with cerebral palsy (CP) receiving care at the SARAH Network of Rehabilitation Hospitals in Brazil.

Main Methods:

A multicentre, cross-sectional, descriptive study was conducted.
Data from 17,771 individuals diagnosed with CP were analyzed.

Main Results:

The predominant form was spastic CP (75.5%) with bilateral involvement (75.9%).
Perinatal risk factors like preterm birth (48.4%) and low birthweight (48.0%) were highly prevalent.
Over half of the participants (57.8%) presented with severe motor impairment (Gross Motor Function Classification System levels III-V).

Conclusions:

Demographic and clinical findings align with those from low- and middle-income countries (LMICs).
Despite improvements in prenatal and perinatal care, severe motor deficits persist in individuals with CP.
Establishing multicentre and national registries in LMICs is vital to tailor family-centered rehabilitation strategies, considering the impact of psychosocial factors.
