Investment Landscape: Mild Cognitive Impairment
Overview
Mild Cognitive Impairment (MCI) represents a critical therapeutic window between normal aging and [Alzheimer's Disease](/diseases/alzheimers-disease) dementia. Defined as objective cognitive impairment beyond age-expected norms with preserved functional abilities[@Petersen2018], MCI affects approximately 15-20% of individuals over 65 and serves as the optimal intervention point for disease-modifying therapies. The 2023-2024 approvals of [lecanemab](/entities/lecanemab) and [donanemab](/entities/donanemab) have validated amyloid-targeting in early-stage disease, fundamentally reshaping the MCI investment landscape[@van2023][@Sims2023].

Clinical Trial Pipeline
MCI represents one of the most active therapeutic areas in neurodegeneration:
| Phase | AD/MCI Trials | Notes | |-------|---------------|-------| | Phase 1 | 480+ | Including prevention cohorts | | Phase 2 | 630+ | Largest concentration of programs | | Phase 3 | 320+ | Amyloid antibodies, symptomatic agents | | Total Active | 1,200+ | Includes MCI-specific and AD with MCI cohorts |
