As we age, our brains might start to get less sharp, making it harder to learn new things or remember key events.

And for some, that cognitive decline could be significant, in some rarer cases leading to Alzheimer's Disease.

When it comes to Alzheimer's, there are more drug failures than successes. On average about 99% of all drugs in clinical trials never actually make it to approval, and drugs are still failing late-stage trials in 2017.

But there are other ways to decrease your risk of getting the disease. We spoke with Neurotrack CEO Elli Kaplan, whose company recently launched an online assessment that helps people understand the state of their memory health, to learn about some of the ways you can potentially decrease your risk for Alzheimer's and cognitive decline more broadly. The company also provides a program that can be used to prevent some of that cognitive decline.

Here's what the science has to say about the best ways to lower your risk of Alzheimer's and cognitive decline.
