Official Title: PiB PET Scanning in Speech and Language Based Dementias
Brief Summary: The study is designed to determine whether there are clinical features that can be used as biomarkers to predict whether underlying Alzheimer's pathology is the cause of a speech and language based dementia. The primary hypothesis is that the proportion of patients who test positive for beta-amyloid deposition will vary across different speech and language based dementias.
