The Asperger syndrome, a less severe variant of autism, has drawn increasing interest among child psychiatrists. Cerebral blood flow studies with autistic subjects have failed to reveal consistent findings. We are reporting a case with the Asperger syndrome, whose single photon emission computed tomography showed left occipital hypoperfusion.
In a patient with fat embolism to the brain CT showed no abnormality. MRI performed after recovery from coma, when the patient had aphasia and quadriparesis, demonstrated multiple high signal abnormalities in the white matter on both T1- and T2-weighted images. HMPAO-SPECT showed left-sided hypoperfusion which resolved in parallel with clinical improvement… (More)
Thirty-three patients fulfilling the clinical criteria for brain death were tested by Brainstem Auditory Evoked Potentials (BAEP) and Radionuclide Cerebral Angiography and Brain Perfusion Studies. There was a significant correlation between the BAEP and radionuclide study outcomes. All patients with absence of BAEP showed no cerebral perfusion. These… (More)
The purpose of our model was to provide maximum pressure level of the middle cerebral artery (MCA) without causing any histological variation like focal cerebral ischaemia. In this experimental study 9 dogs were used. A modified Spetzler occluder was applied to the MCA of the dogs to determine regional cerebral blood flow (rCBF) and somatosensory evoked… (More)
