Why does dementia look so different from one family to the next? This is a question I hear from caregivers all the time. Two people can have the same diagnosis and be the same age, yet their symptoms and caregiving challenges can look completely different.

In this video, I break down what the 2025 NIH dementia progress report helps explain about why dementia does not follow one clear or predictable path. I cover what researchers are learning about dementia risk and protection, what is happening in the brain beyond memory loss, and what the science is showing about care planning and the caregiving experience.

This is Part 2 of a two-part series based on the 2025 NIH dementia research update.
