Brain SPECT scans in students with specific learning disability

Abstract

Brain SPECT scan may serve as a robust tool to identify changes in regional brain perfusion in students with SpLD.

Brain SPECT scans

“…For the first time, the present study by Karande et al . [10] has attempted a quantitative assessment of brain perfusion in such students. Furthermore, the authors performed brain SPECT scans not only at rest but after stimulation by learning as well.…”

“…Furthermore, the authors performed brain SPECT scans not only at rest but after stimulation by learning as well. [10] Visual analysis showed reduction of regional blood flow both in the “baseline scans” and the “test scans” in the temporoparietal areas of all nine students. However, when they attempted to compare the data using NeuroGam™ software, there was no statistically significant change in regional perfusion in the temporoparietal areas.…”

“…However, when they attempted to compare the data using NeuroGam™ software, there was no statistically significant change in regional perfusion in the temporoparietal areas. [10] Ways for improving on this study include increasing the number of study subjects and locating as many detailed lesions of SpLD as possible. In addition, another fMRI brain study has indicated that this disorder may be caused by specific deficits or atypical asymmetries in the left posterior superior temporal gyrus and left supramarginal gyrus.…”
