Periventricular Leukomalacia (PVL) is a white matter lesion surrounding the lateral ventricles of the brain occurring in the prenatal period, associated with a disorder of movement and posture, known as bilateral cerebral palsy. Children with PVL and bilateral cerebral palsy have spared verbal abilities, as measured by verbal Intelligence Quotient (verbal IQ) tests, while non-verbal intelligence and especially visuo-perceptual and visuo-spatial abilities are impaired. In addition some studies underline the impact of PVL also on executive function, especially in terms of working memory and in the ability to inhibit distraction.
