ABSTRACT
Introduction. Autistic disorder is formed by a group of
abnormalities, which include qualitative impairments in
communication, reciprocal social interactions, as well as
the adoption of stereotyped repetitive behavior patterns
and restrictive.
Objective. Identify the differences in regional cerebral
perfusion measured by SPECT technique in children with
autistic disorder compared to control children.
Material and methods. We performed a prospective,
transversal, comparative, observational pediatric patients
with autism and a control group, conducted a brain scan
technique to quantify cerebral perfusion SPECT in the
frontal lobes, parietal, occipital, temporal and Brodman
areas in its left and right hemispheric parts: 1, 2, 3, 4, 6, 8,
9, 10, 17, 18, 19, 22, 41, 44, 45. Drug was used radio tc-
99m ethyl cysteine dimer bike, images were processed
using the protocol Talairach brain imaging that allowed
quantification of brain activity in account activity for each
area of interest, we analyzed the characteristics and differences
in cerebral perfusion for each of the segments studied
in both study groups.
Results. Autistic patients show an increase in cerebral
perfusion of the right frontal lobe (54.4
vs. 48.7%) (p ‹
0.04385). Also have loss of cortical perfusion asymmetry
of the frontal lobes (54.4
vs. 54.7%) (p = 0.6816).
Conclusions. Patients showed asymmetry constant
control of cerebral perfusion between right and left frontal
lobe (55.1
vs. 48.6%) (p ‹ 0.004586). Autistic patients
show increased cerebral perfusion in Brodmann area 45
of right. (60.4
vs. 54.3%) (p = 0.0500).
