The recent development of a PET tracer,\[18F\]MK-6240(an\[18F\]tau imaging agent,CerveauTechnologies)that has high affinity for the human phosphorylated tau deposits in AD brain offers new opportunities to investigate tau pathology. The investigators will evaluate this imaging agent in individuals from families with a known Autosomal Dominant Alzheimer's Disease (ADAD) mutation. This study of tau PET using \[18F\]MK-6240 is performed in conjunction with DIAN and DIAN Extended Registry (DIAN-EXR).
Inclusion Criteria: 1. Participants have met all eligibility criteria for enrollment into the Dominantly Inherited Alzheimer's Network (DIAN) and DIAN Extended Registry (DIAN EXR) study enrollment criteria. 2. Male or female participants, at least 18 years of age. 3. Cognitively normal, or with mild dementia, as assessed clinically. 4. Participant is able and willing to undergo testing (magnetic resonance imaging (MRI)or computed tomography (CT), PET, radioactive tracer injection; forthose unable to undergo MRI, CT will be used to generate regions-of interest). 5. Pre-menopausal women will un…
PET tracer, \[18F\]MK-6240 (an\[18F\]tau imaging agent,CerveauTechnologies)that has high affinity for the human phosphorylated tau deposits in AD brain offers new opportunities to investigate tau pathology.(Hostetler, Walji et al. 2016, Lohith, Bennacef et al. 2016, Walji, Hostetler et al. 2016, Lohith, Bennacef et al. 2017, Neelamegam, Yokell et al. 2017).We will evaluate this imaging agent in individuals from families with a known Autosomal Dominant Alzheimer's Disease (ADAD) mutation. The planned dosage for \[18F\]MK-6240 is a single intravenous bolus injection of 185 MBq (5.0 mCi) in a large peripheral vein followed by a 10 mL normal saline (0.9% NaCl) flush.
