The Essential Bundle is built for several groups. Healthy adults 25 and older who want to baseline their brain aging and track it over time, especially those with a family history of Alzheimer's or APOE4 carriers. High-performers, founders, executives, and professionals who depend on being at their sharpest and want to protect and optimize cognitive performance. And people with mild cognitive impairment (MCI) or early Alzheimer's who want to monitor their trajectory and work to discuss next steps. You do not need symptoms to benefit, and you do not need to be symptom-free either. The earlier you establish a baseline, the more useful the data becomes.
