Magnetic resonance diffusion tensor imaging for neurodevelopmental disorders in children

Area of Science:

• Neuroimaging
• Pediatric Neurology
• Biomarkers

Background:

• Neurodevelopmental disorders (NDDs) affect children's cognitive and motor functions.
• Accurate assessment of neurological dysfunction in NDDs is crucial for timely intervention.
• Diffusion Tensor Imaging (DTI) offers insights into white matter microstructure.

Purpose of the Study:

• To evaluate the utility of DTI in pediatric NDDs.
• To assess the role of fractional anisotropy (FA) as a biomarker for neurological dysfunction severity in NDDs.

Main Methods:

• A cohort of 91 children with NDDs and 21 controls underwent DTI.
• Fractional anisotropy (FA) values were measured in specific brain regions, including the globus pallidus and posterior limb of the internal capsule.

Main Results:

• Children with NDDs exhibited significantly lower FA values in the globus pallidus and posterior limb of the internal capsule compared to controls.
• FA values decreased progressively with increasing severity of NDDs.
• These reductions were statistically significant (P < 0.05).

Conclusions:

• DTI is a valuable tool for understanding NDDs in children.
• FA changes in the globus pallidus and posterior limb of the internal capsule are associated with NDD severity.
• These FA alterations may serve as effective biomarkers for assessing neurological dysfunction in pediatric NDDs.
