Apraxia of speech can be the only manifestation of a neurodegenerative disorder. However, AOS very often co-occurs with aphasia, particularly a…
Inclusion Criteria: * We will study subjects that fulfill clinical inclusion criteria for neurodegenerative AOS that have been seen and diagnosed at Mayo Clinic Exclusion Criteria: * Subjects with concurrent illnesses that could account for speech and language deficits, such as traumatic brain injury, strokes or developmental syndromes will be excluded. * Women that are pregnant or post-partum and breast-feeding will be excluded. All women who can become pregnant must have a pregnancy test no more than 48 hours before the PET scan. * Subjects will also be excluded if MRI is contraindicated…
