The goal of this study is to determine the best diagnostic test for diagnosing frontotemporal lobar degeneration. To accomplish this, the current study will evaluate different tests: brain imaging, skin biopsy, body fluid samples (blood and cerebrospinal fluid), thinking abilities, everyday functioning, and brain autopsy. The study team hopes that this information can be used to guide diagnosis and further understanding of mechanism of disease in Frontotemporal Lobar Degeneration and possibly treatment in the future.

History of traumatic brain injury, brain tumors, stroke or other neurological or psychiatric disorders that can explain symptoms will be excluded.
Premenopausal women will be asked to consent to a pregnancy test prior to each scan as pregnant women will be excluded from study because of potential harm to fetus from PET study.
