Summary

This trial looks at amyloid and tau in the brains of people with atypical Alzheimer's to see how it changes over time.

Who is the study for?
This study is for adults over 21 with Atypical Alzheimer's Disease, specifically those diagnosed with Logopenic Aphasia or Posterior Cortical Atrophy. Participants must have a person to report on their functioning and speak English as their primary language. They can't join if they've had strokes, tumors, severe memory issues early on, other neurodegenerative diseases, very poor vision, are pregnant/breastfeeding, or have MRI contraindications.
What is being tested?
The trial is using advanced brain imaging techniques (F-18 AV 1451 and C-11 PiB) to investigate the presence of amyloid and tau proteins in patients' brains. It aims to see how these protein levels change over one year in individuals with atypical forms of Alzheimer's disease.
What are the potential side effects?
While the document doesn’t specify side effects related to F-18 AV 1451 and C-11 PiB imaging agents used in PET scans directly, common side effects from such procedures may include discomfort at injection site or allergic reactions; however individual experiences may vary.
