Cognitive Leisure and Preclinical Alzheimer's Disease: Exploring Neural Mechanisms

This study is investigating whether mentally stimulating leisure activities — such as reading, puzzles, or learning new skills — can protect brain function in older adults who are in the early stages of cognitive decline that may be related to Alzheimer's disease. Researchers will use brain scans (MRI) to understand how these activities affect neural circuits involved in memory and thinking. **You may be eligible if...** - You are 60 years old or older - You have been diagnosed with mild cognitive impairment (MCI) or subjective cognitive decline (SCD — meaning you feel your memory or thinking has worsened, even if tests are still normal) - You can communicate in Mandarin - You have basic comprehension and judgment ability **You may NOT be eligible if...** - You have severe hearing or speech problems that prevent participation - You have serious physical illness that prevents cooperation with the study - You have a pacemaker, metal implants, cochlear implants, claustrophobia, or other reasons you cannot undergo an MRI scan Talk to your doctor to see if this trial is right for you.
