This market is projected to grow at a Compound Annual Growth Rate (CAGR) of 17.5% to reach $14.8 billion by 2026, driven by the increasing prevalence of AD and mild cognitive impairment (MCI), as well as the adoption of novel disease-modifying therapies[3].

The drug's promotional mix included sales rep detailing, physician education, and paid speaking engagements. Over 5,300 paid interactions were recorded, involving more than 975,000 U.S. healthcare professionals. The report highlights that the depth of coverage varied within key specialties such as Family Medicine, Internal Medicine, Neurology, and Psychiatry, with Neurology and Psychiatry being the most targeted areas[1].
