Presenilin-1-associated abnormalities in regional cerebral perfusion.

OBJECTIVE To investigate the influence of the presenilin-1 gene (PS-1) mutation on regional cerebral perfusion, SPECT was evaluated in 57 individuals. The subjects were members of a large pedigree from Colombia, South America, many of whom carry a PS-1 mutation for early-onset AD. METHODS Members of this large kindred who were cognitively normal and did not carry the PS-1 mutation (n = 23) we...

Abnormalities of cerebral perfusion in multiple sclerosis.

BACKGROUND Measuring perfusion provides a potential indication of metabolic activity in brain tissue. Studies in multiple sclerosis (MS) have identified areas of decreased perfusion in grey matter (GM) and white matter (WM), but the pattern in clinical subgroups is unclear. OBJECTIVES This study investigated perfusion changes in differing MS clinical subgroups on or off beta-interferon therap...

Regional cerebral perfusion abnormalities in developmental language disorder. Statistical parametric mapping analysis.

OBJECTIVE A voxel based investigation of cerebral blood flow was conducted to identify brain functional differences during resting state between children with developmental language disorder (DLD) and normal controls. METHOD Using DSM-IV criteria, we selected 21 children with DLD. All children were examined by technetium-99m-HMPAO Brain SPECT. Using SPM analyses, we compared the SPECT images ...

Cerebral perfusion abnormalities in cases of Down syndrome.

A SPECT (single photon emission computed tomography using Tc-99m HMPAO) study of brain with segmental quantitative analysis was conducted to access the cerebral perfusion in cases of Downs syndrome (DS). Varying level of brain hypo-perfusion was documented, probably explaining the neurophysiologic basis of cognitive and neuropsychological deficits, which are not well understood in DS.

Regional myocardial perfusion after experimental subarachnoid hemorrhage.

BACKGROUND AND PURPOSE The pathophysiology of cardiac injury after subarachnoid hemorrhage (SAH) remains controversial. Data from animal models suggest that catecholamine-mediated injury is the most likely cause of cardiac injury after SAH. However, researchers also have proposed myocardial ischemia to be the underlying cause, as a result of coronary artery disease, coronary artery spasm, or hy...
