Comprehensive Summary of Brain Imaging and ADHD
“Anatomical assays using quantitative MRI of the brain have provided insights into the neuroanatomical substrate. Early studies suggested that individuals with ADHD had smaller total cerebral volume and showed loss of the normal asymmetry in the size of the caudate nucleus (Castellanos et al., 1996). These data also showed decreased volumes of the right globus pallidus, right anterior frontal region and cerebellum. While PET studies in adult volunteers have provided new knowledge about the pharmacokinetic properties of methylphenidate at its primary site of action in the brain, morphometric and functional neuroimaging have illuminated the neural correlates of abnormalities in both children and adults diagnosed with ADHD (Castellanos and Tannock, 2002; Giedd et al., 2001).“
