Neuroimaging of Babies During Natural Sleep to Assess Typical Development and Cerebral Palsy
Trial Parameters
Brief Summary
Background: Early diagnosis of cerebral palsy (CP) is crucial, enabling intervention when neuroplasticity is at its highest. Magnetic resonance imaging (MRI) plays a vital role in CP diagnosis. Currently, diagnostic MRI of newborns and infants with suspected brain damage relies heavily on structural MR images. The current study aims to i) establish procedures for clinical infant and toddler MRI during natural sleep, ii) use advanced MRI sequences, such as advanced diffusion-weighted imaging (DWI), that may be more sensitive in detecting early brain damage, and iii) map relationships between early brain development, and motor function and development. Methods: The NIBS-CP study will enroll approximately 200 infants either at risk for CP or typically developing. Infants will be followed longitudinally (for three waves) between 3 months and 2 years of age with cerebral MRI at 3 Tesla and comprehensive assessments of motor and cognitive functioning. The MRI protocol includes advanced diffusion-weighted imaging, high-resolution structural MRI, and MR spectroscopy. The motor and cognitive assessments include Hand Assessment in Infants, Alberta Infant Motor Scales, Hammersmith Infant Neurological Examination, Peabody Developmental Motor Scales, Bayley Scales of Infant Development, and Ages and Stages Questionnaires. NIBS-CP aims to establish normative material on early brain development of Danish children and conduct normative modeling of typical and atypical development to identify deviations in brain development at the level of the single child. Discussion: Identifying predictive brain structural features of motor function and motor development is key to the future use of early MRI in the clinical work-up, as this promotes early diagnosis and (clinical) intervention strategies tailored to the individual child.
