[Neuropsychological aspects of acquired diffuse brain injury in paediatric childhood].

INTRODUCTION AND DEVELOPMENT: Acquired brain injury is one of the most common causes of long-term disability in childhood and traumatisms are the most prevalent cause. Diffuse axonal injury is associated with poor neuropsychological outcome. In contrast to early focal lesions, young age confers no advantage in the outcome of severe diffuse brain injury. Plasticity is incomplete for structural and functional deficits in children. The traditional view of enhanced reorganization of function after localized brain injury it can't be applied in early severe diffuse brain injury. In the paediatric population where the central nervous system is in a rapid state of growth, developmental factors may mask the difficulties and deficits in certain skills may not be evident until that skill is expected to emerge at a certain age.

CONCLUSION: Like in adults the neuropsychological domains more affected in childhood are psychomotor speed, memory, attention and executive functioning. In childhood neuropsychological deficits will affect learning and adaptive behaviour. Sometimes deficits will be cumulative over time.
