Abstract
Objective: To describe differences in cerebral glucose metabolism between frontotemporal lobar degeneration (FTLD) and Alzheimer's disease (AD). Methods: 14 patients with FTLD (7 f/7 m, mean age 60.1 years) and 14 patients with AD (7 f/7 m, mean age 59.5 years) were examined. [18F]FDG positron emission tomography (PET) scans were analysed with statistical non-parametric mapping (SnPM) and ...
Abstract
Objective: To describe differences in cerebral glucose metabolism between frontotemporal lobar degeneration (FTLD) and Alzheimer's disease (AD). Methods: 14 patients with FTLD (7 f/7 m, mean age 60.1 years) and 14 patients with AD (7 f/7 m, mean age 59.5 years) were examined. [18F]FDG positron emission tomography (PET) scans were analysed with statistical non-parametric mapping (SnPM) and statistical parametric mapping (SPM99). Results: Significant decreases in glucose metabolism in FTLD compared to AD were detected in the left insula/left inferior frontal gyrus (Brodman area [BA]13, 45 and 47) and in the medial frontal gyrus bilaterally (BA10). A significant decrease in AD compared to FTLD was identified in the right middle temporal gyrus (BA39). Conclusion: Cerebral PET could be a promising tool to discriminate FTLD from AD.
