Department of Psychiatry and Clinical Psychobiology, University of Barcelona, Barcelona, Spain
J Child Neurol 18:845-50. 2003..Frontal function was the only cognitive function on which subjects with dyskinetic cerebral palsy had lower scores. We conclude that the neuropsychologic profiles of dyskinetic and spastic cerebral palsy are different... - Quantitative signal intensity measures on magnetic resonance imaging in attention-deficit hyperactivity disorderRoser Pueyo
