Target Audience

The educational design of this activity addresses the needs of physicians, nurse practitioners, and other allied health care professionals who treat patients with Alzheimer's disease (AD).

Educational Objective

After completing this activity, the participant should be better able to:

  • Discuss clinically relevant aspects of AD pathophysiology, including amyloid β and tau
  • Describe challenges, results, and future directions with emerging therapies for AD

Statement of Need

AD is a common neurodegenerative condition that results in a range of profoundly disabling cognitive, affective, and behavioral symptoms. It affects approximately 5.8 million Americans.1 Barring significant clinical efforts and medical breakthroughs that prevent or slow disease development, current estimates suggest that by 2050, AD will afflict 14 million patients in the United States.1 Clearly, the development of AD is complex, presenting a target-rich clinical environment for both diagnostic approaches and therapeutic interventions. Amyloid plaques and neurofibrillary tangles are the primary pathophysiologic characteristics of AD.2 Among other approaches, amyloid-targeted therapies have been directed toward protofibrils, monomers, oligomers, and existing plaques.3 Neurofibrillary tangles have emerged as another therapeutic target over the last several years, including agents targeting tau expression, stabilizing tau conformations, or clearing tau aggregates.4 Thus far, amyloid-targeted therapies are further advanced in clinical development, and as the potential for approval grows, clinicians must be aware of mechanism of action, clinical trial data, and patient selection. In this activity, Dr. Cohen reviews the pathophysiology of AD, individual therapeutic targets, and amyloid- and tau-directed therapies as well as other therapeutic approaches.
