This study looks at whether older adults with Alzheimer's disease (AD) can learn to prevent falls through a special training called **perturbation training**. Perturbation training helps people learn balance skills by simulating unexpected movements, like those on a treadmill. **Alzheimer's disease** is a condition that affects memory and thinking skills, increasing fall risks. The study will have two groups: one will do the training, and the other will not. Both groups will experience similar movements in the lab and at home over six months. The study will check if the trained group has fewer falls. To join, participants must be 65 or older, diagnosed with probable AD, and able to walk and stand independently. Some health conditions might exclude participation, like low or uncontrolled high blood pressure, or other mental health issues.
