Longitudinal Imaging in Progressive Apraxia of Speech

This study is looking at how changes in the brain, seen through imaging, relate to the progression of speech and language problems in people with neurodegenerative apraxia of speech (AOS). AOS is a disorder that affects how you produce speech. Researchers will use a drug called AV-1451 to help them see "Tau burden" in the brain, which is a protein linked to certain brain diseases. You might be able to join if you are 18 or older and have been diagnosed with neurodegenerative AOS at Mayo Clinic. People with other illnesses that could explain their speech problems, like a stroke, cannot join. The study aims to see how changes in brain images over about 1-2 years connect with changes in your speech and other abilities during that time. The current status of this study is unclear.

Eligibility criteria

Exclusion

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.
