Alzheimer’s Disease | Treatment Algorithms | Claims Data Analysis | US | 2021

For the 3.8 million people in the United States with Alzheimer’s disease (AD) dementia, approved pharmacotherapy is limited to only modestly effective procognitive symptomatic agents (e.g., donepezil, memantine). Understanding today’s treatment landscape is important for emerging players as the heavily generic AD therapy market prepares for the potential entry of new, high-cost brands—namely, landmark disease-modifying therapies and new behavioral adjuncts. Our Treatment Algorithms: Claims Data Analysis content provides national patient-level claims data to explore the use of key therapies in both newly diagnosed and recently treated patients.


  • What patient shares do key therapies and brands garner by line of therapy in newly diagnosed AD patients? What are the quarterly trends in prescribing among recently treated and newly diagnosed AD patients?
  • What is the dynamic between memantine IR/XR formulations now that both are generic? How has Namzaric been integrated into the treatment algorithm, and what is its source of business?
  • What percentage of AD patients receive drug therapy within two years of diagnosis, and how quickly? What percentage of patients progress to later lines of therapy within two years of diagnosis?
  • What percentage of AD patients are treated with monotherapy vs. combination therapy? What are the most commonly used combinations?
  • What are the product-level compliance and persistency rates among drug-treated patients?
