Differential neuropsychological profiles in children and adolescents with motor disability in an inclusive educational setting.

The aim of this study was to determine the potential cognitive impairment associated with motor disability in a group of children attending regular schools and to analyze whether there were different cognitive profiles according to the type of motor disability they presented. The study had 87 participants, 31 healthy and 56 with three types of motor disability: Neuromuscular Diseases (NMD Group), Cerebral Palsy-Hemiparesis (CP- HPx Group) and Cerebral Palsy-Diplegia (CP-DP). Ages ranged from 6 to 18 years and they had medium and medium-high socioeconomic and cultural levels. All participants attended regular state-funded and independent schools in an inclusive modality. The neuropsychological assessment included the following cognitive domains: processing speed, working memory, verbal and visual episodic memory, language, visuo-perception and constructive praxis and executive functioning. A second analysis was performed with the groups with CP: one based on the severity of gross motor impairment (GMFCS-E&R scale) and the other based on the levels of manual dexterity (MACS scale). ANCOVAs were performed controlling for age and processing speed in the three analyses. The group with CP-HPx was shown to be the most cognitively impaired of the three groups, with significant deficits in visuo-perception, verbal working memory, and visuo-spatial memory. Subjects with greater gross motor dysfunction (GMFCS-E&R) did not show the greatest cognitive impairment, while those with worse manual dexterity (MACS) exhibited greater cognitive impairment. Children and adolescents with motor disabilities, a priori cognitively normal, present different levels of cognitive impairment. This should be considered when planning educational adaptations for this infant-juvenile population.
