Spastic diplegia in preterm-born children: Executive function impairment and neuroanatomical correlates.
Kids with spastic diplegia from preterm birth often have hidden executive-function deficits—screen these domains, not just motor skills.
01Research in Context
What this study did
Pino et al. (2017) looked at kids with spastic diplegia after preterm birth. They tested attention, planning, and motor skills. They also took brain scans to see where white-matter was missing.
The team compared these kids to typically developing peers. They wanted to know if hidden thinking problems tracked with callosum damage.
What they found
More than half the diplegia group failed attention and executive tasks. They also showed clear visuo-spatial gaps. The worse the scores, the thinner the front part of the corpus callosum.
Gross motor scores alone missed these deficits. Only wide testing showed the full picture.
How this fits with other research
Franki et al. (2020) pooled CP imaging studies and found weak links between lesion type and motor severity. Chiara’s work sharpens the story: callosal thinning does predict thinking skills, just not gross motor scores.
Tomita et al. (2016) showed that anticipatory postural control worsens with GMFCS level. Chiara adds that thinking control can be poor even when standing looks fair.
Griffith et al. (2012) saw attention problems in moderately preterm kids. Chiara shows the same risk persists into diplegic CP, tied to callosal loss.
Why it matters
If you only test gait or range of motion, you will miss half the problem. Add quick executive screens like the Trail Making or Stroop color test. Thin anterior callosum on MRI is your red flag to refer for full neuro-psych testing. Targeting attention and planning could boost therapy gains more than motor drills alone.

03Original abstract
BACKGROUND: The neuropsychological literature on preterm-born children with spastic diplegia due to periventricular leukomalacia is convergent in reporting deficits in non-verbal intelligence and in visuo-spatial abilities. Nevertheless, other cognitive functions have found to be impaired, but data are scant and not correlated with neuroimaging findings. AIMS: This study analyzes the neuropsychological strengths and weaknesses in preterm-born children with spastic diplegia (pSD) and their relationships with neuroanatomical findings, investigated by a novel scale for MRI classification. METHODS AND PROCEDURES: Nineteen children with pSD, mild to moderate upper limb impairment and Verbal IQ>80, and 38 normal controls were evaluated with a comprehensive neuropsychological battery (NEPSY-II), assessing Attention/Executive Functioning, Language, Memory, Sensorimotor, Social Perception and Visuospatial Processing domains. The MRIs were quantitatively scored for lesion severity. OUTCOMES AND RESULTS: The results showed that, beyond core visuo-spatial and sensory-motor deficits, impairments in attention and executive functions were present in more than half of the sample, particularly in children with damage to the anterior corpus callosum. CONCLUSIONS AND IMPLICATIONS: The findings are discussed in terms of clinical and rehabilitative implications tailored for pSD subgroups diversified for neuropsychological and neuroanatomical characteristics.
