Neuroimaging Patterns and Function in Cerebral Palsy-Application of an MRI Classification

Area of Science:

• Neurology
• Pediatrics
• Radiology

Background:

• Cerebral palsy (CP) is a complex neurological disorder affecting movement and posture, with individual functional profiles.
• Magnetic resonance imaging (MRI) provides insights into brain compromise, aiding in understanding CP's localization, nature, and severity.
• The MRI Classification System (MRICS) by SCPE reliably categorizes MRI patterns linked to specific brain vulnerability timings in CP.

Purpose of the Study:

• To apply the MRICS to a large dataset of children with CP.
• To describe the functional profiles associated with different MRICS neuroimaging patterns.
• To correlate MRI findings with motor and associated impairments for improved counseling and service planning.

Main Methods:

• Utilized data from 3,818 children with CP and post-neonatal MRI from 20 European registers (JRC-SCPE Central Registry).
• Applied CP classification, MRICS, Gross Motor Function Classification System (GMFCS), and Bimanual Fine Motor Function (BFMF) classifications.
• Documented associated impairments (intellectual, epilepsy, visual, hearing) and calculated an impairment index for severity.

Main Results:

• Significant differences in CP type, motor, and associated impairments were observed across neuroimaging patterns.
• Functional profiles were described for each MRICS pattern.
• Bilateral brain findings were associated with more severe motor and associated impairments compared to unilateral compromise.

Conclusions:

• The MRICS effectively categorizes CP based on neuroimaging patterns.
• Specific functional profiles and impairment severities are linked to distinct MRI patterns.
• Findings on uni- vs. bilateral brain compromise can inform counseling and service planning for children with CP.
