Functional Deficits in Autistic Disorder: Characterization by Technetium-99m-HMPAO and SPECT
Page 1 tism is an early and severe developmental disorder characterizedby deficits in verbal and …

The authors examined specific deficits of cerebral blood perfusion in autistic patients as
measured with [99mTc] HMPAO single-photon emission computed tomography (SPECT) …

The purpose of the study was to investigate perfusion patterns in autistic children (AC) and
their families. Ten AC (9 boys, 1 girl; mean age: 6.9±1.7 years) with autistic disorder defined …

SPECT with Tc-99m-HM-PAO was used in examining 31 patients with autism and autistic-
like conditions. Sixteen of these had autistic disorder/autistic-like conditions with associated …

The aim of this study is confirmation of an abnormal regional cerebral blood flow (rCBF)
pattern in high-functioning autism (HFA). Confirmation of an abnormal rCBF pattern in HFA …

Stuctural brain abnormalities have recently been discovered using magnetic resonance
imaging in infantile autism, a neurodevelopmental disorder of unknown etiology. However …

Childhood autism is a developmental disability of unknown origin with probable multiple
etiologies. The purpose of this study was to compare the changes of regional cerebral blood …

The neuro-anatomical substrate of autism has been the subject of detailed investigation.
Because previous studies have not demonstrated consistent and specific neuro-imaging …

Methods: Fifty-one patients (31 boys, 20 girls; age range 6 mo to 6 yr, 11 mo) with clinical
manifestations of cerebral palsy underwent brain SPECT after intravenous injection of"" Tc …

OBJECTIVE: The nature of the underlying brain dysfunction of childhood autism, a life-long
severe developmental disorder, is not well understood. Although researchers using …
