In this study, the neuroanatomy of 11 females with Rett syndrome and 15 age\u2010 and gender\u2010matched control subjects ws investigated in vivo with quantitative neuroimaging techniques. Compared to control subjects, the patients with Rett syndrome were found to have significantly reduced cerebral volume; evidence of greater loss of gray matter in comparison to white matter; regional variation in cortical gray matter, with the frontal regions showing the largest decrease; and reduced volume of the caudate nucleus and midbrain, even when taking into account general reduction in the size of the brain. In addition, there was no evidence of an ongoing degenerative process in this sample of girls with Rett syndrome. The consistency of these data with results from neuropathological investigations points to the need for continued quantitative neuroimaging studies of children with this condition. In particular, research employing serial longitudinal scans of very young children manifesting early signs of the clinical syndrome holds promise for helping to elucidate the neuropathological pathways leading to the debilitating clinical manifestations of Rett syndrome.<\/jats:p>","DOI":"10.1002\/ana.410340220","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T00:24:54Z","timestamp":1104539094000},"page":"227-234","source":"Crossref","is-referenced-by-count":176,"title":["Neuroanatomy of Rett syndrome: A volumetric imaging study"],"prefix":"10.1002","volume":"34","author":[{"given":"Allan L.","family":"Reiss","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Faisal","family":"Faruque","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sakkubai","family":"Naidu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Abrams","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Terri","family":"Beaty","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
