| Description | The objectives of the paper are to review current findings of the neuroimaging methods in hyperkinetic disorder and to interpret them in the context of contemporary neurobiological concepts of brain structure and function. Neuroimaging brings about substantial body of evidence that enables rethinking of the neurobiology beyond the traditional concept of fronto-striatal dysfunction. Several other brain regions seems to be involved: dorso- and ventrolateral prefrontal cortex, orbitofrontal cortex, superior parietal regions, caudate, talamus, amygdala, and cerebellum. Attention shifts towards more systemic view at the level of neuronal nets with connectivity as a crucial factor. In hyperkinetic disorder findings of abnormal white matter tracts integrity as well as functional dysconnectivity were observed. This larger impairment is mirrored by the clinical manifestation of the disease that is much more complex than disorder of attention or hyperactivity Neurobiological heterogeneity of the hyperkinetic disorder is another concept that emerges from the neuroimaging findings. Imaging methods show also certain differences in the neurobiological impairment between children and adult patients; the clinical meaning of this finding is, however, unclear yet. Unfortunately, the lack of information on the neuropathological substrate of the neuroimaging findings prevents deeper understanding of their significance. |
