Abstract
FTLD (Frontotemporal lobar degeneration) is a clinically and pathologically heterogeneous group of degenerative disorders, characterized by predominantly asymmetric degeneration of frontal and temporal lobes with selective neuronal loss and gliosis. The disease presents with variable degrees of impairment in behavior, language, executive control, and motor symptoms with progressive loss of cognition. On the basis of presenting clinical symptoms, FTLD is further divided into behavioral variant, nonfluent/agrammatic variant primary progressive aphasia (PPA), semantic variant PPA, logopenic variant PPA, progressive supranuclear palsy, and corticobasal ganglionic degeneration. Here we illustrate the utility of FDG PET with statistical parametric analysis for evaluation of these patients.
