“…Multiple independent single photon emission computed tomography (SPECT) and positron emission tomography (PET) research studies have demonstrated hypoperfusion to several areas of the autistic brain, most notably the temporal lobes [26][27][28][29][30][31][32][33][34][35][36][37][38][39]. Several studies show that reduced blood flow to the temporal regions and other brain areas correlates with many of the clinical findings associated with autism including repetitive, self-stimulatory and stereotypical behaviors, and impairments in communication, sensory perception, and social interaction [27,29,31,[39][40][41][42].…”

“…FDG PET has been used to characterize cerebral metabolism in different groups of PDD patients (Happe et al, 1996) and under different conditions, such as resting (George, Costa, Kouris, Ring, & Ell, 1992;Hashimoto et al, 2000;Ohnishi et al, 2000), sleeping (Zilbovicius et al, 1995), and while under stress (Buchsbaum et al, 1992;Muller et al, 1998;Siegel et al, 1992;Siegel, Nuechterlein, Abel, Wu, & Buchsbaum, 1995). Most studies agree that the benefits of imaging are greater than the risks of anesthesia required in this group of patients (Curry et al, 1997 …”

“…A discreta redução dos volumes de ambos hipocampos 2 ; o afilamento da porção posterior do corpo do corpo caloso 18,14,20 ; a hipogenesia global do corpo caloso 18,20 ; a hipogenesia do esplênio do corpo caloso 12,14,15,18,20 ; a discreta dilatação dos ventrículos laterais 14 ; a polimicrogiria occipital bilateral foram encontradas em nossos resultados, tornando-se concordantes com a literatura . As alterações cerebelares como a redução de volume e o alargamento do IV ventrículo, encontradas em nosso estudo têm sido ponto de divergência entre os autores 21,22 . As alterações do volume cerebral, para mais ou para menos, têm sido relatadas 6,10,16,23 .…”

“…A diminuição da perfusão sanguínea no hemisfério cerebelar, no tálamo e nos gânglios da base já foi demonstrada 21 . Há registros de que, em pacientes portadores de TA, com RNM normal, essa diminuição na perfusão, é mais encontrada nos hemisférios cerebelares e no tálamo e menos comuns nos gân-glios da base, nas regiões posteriores do lobo parietal e nas regiões temporais 21,22 .…”
