Dysfunctional Brain Networks Behind Speech-stealing Dementia Revealed

Illustration of the three brain regions associated with speech production and the networks between them that, when broken, lead to speech impairments. Solid orange lines depict significantly lower connectivity between brain regions (in red) in PPA. IFG = Inferior Frontal Gyrus; MTG = Middle Temporal Gyrus; ATL = Anterior Temporal Lobe. PPA = Primary Progressive Aphasia; PPA-G = Nonfluent/agrammatic variant of PPA; PPA-L = Logopenic variant of PPA; PPA-S = Semantic variant of PPA. Credit: Northwestern University
