Brain lesion scores obtained using a simple semi-quantitative scale from MR imaging are associated with motor function, communication and cognition in dyskinetic cerebral palsy.


ABSTRACT:

Purpose

To characterise brain lesions in dyskinetic cerebral palsy (DCP) using the semi-quantitative scale for structural MRI (sqMRI) and to investigate their relationship with motor, communication and cognitive function.

Materials and methods

Thirty-nine participants (19 females, median age 21y) with DCP were assessed in terms of motor function, communication and a variety of cognitive domains. Whole-head magnetic resonance imaging (MRI) was performed including T1-MPRAGE, T2 turbo spin echo (axial plane), and fluid attenuated inversion recovery images (FLAIR). A child neurologist visually assessed images for brain lesions and scored these using the sqMRI. Ordinal, Poisson and binomial negative regression models identified which brain lesions accounted for clinical outcomes.

Results

Brain lesions were most frequently located in the ventral posterior lateral thalamus and the frontal lobe. Gross (B?=?0.180, p?p?=?.003; B?=?0.540, p?p?p?p?p?=?.023), and corpus callosum involvement (B?=?-0.448, p?p?=?.007) and medial dorsal thalamus involvement (B?=?-0.139, p?ConclusionsKey clinical outcomes in DCP are associated with specific observable brain lesions as indexed by a simple lesion scoring system that relies only on standard clinical MRI.
