Brief Summary
The study is designed to determine the relationship between structural and functional changes in the brain on imaging and progression of speech and language, neurological and neuropsychological features in patients with neurodegenerative apraxia of speech (AOS).

Outcome Measures
Primary Outcomes (1)
measurement of longitudinal change in neuroimaging and the correlation between change on serial imaging measures and concurrent change on longitudinal measures of clinical performance in neurodegenerative AOS with or without non-fluent aphasia (NFA)
approxiamtely 1-2 years after baseline imaging
Study Arms (1)
Tau positron emission tomography (PET)
EXPERIMENTALAll subjects will receive Tau PET scan on approximately day 1 or day 2 of study to assess Tau burden in the brain.
Interventions
Eligibility Criteria
You may not qualify if:
- 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 (metal in head, cardiac pace maker, e.t.c.), if there is severe claustrophobia, if there are conditions that may confound brain imaging studies (e.g. structural abnormalities, including subdural hematoma or intracranial neoplasm), or if they are medically unstable or are on medications that might affect brain structure or metabolism,(e.g. chemotherapy).
- Subjects will also be excluded if they do not have an informant, or do not consent to research.
