This study looks at how the brain changes in people with movement or memory issues, like Alzheimer's and Lewy body disease. **Researchers will use tests** such as memory quizzes, thinking exercises, brain scans (like MRI), and EEG (which checks brain and muscle activity) to understand these changes. They will compare results from both healthy individuals and those with these disorders.

**Key Points to Consider:**

• Participants need to speak English, undergo tests, and may need a study buddy familiar with their daily routine.
• The study is open to healthy people and those diagnosed with Alzheimer's or Lewy body disease by a certified neurologist.
• **Exclusions**: People with certain medical issues, implanted devices, or pregnancy cannot join. Also, those with anxiety in small spaces or metal-related work injuries might not be eligible.

Participation is voluntary, and you can leave anytime. If you join, you'll receive a copy of the consent form you signed. The study aims to enhance understanding of these brain disorders.
