Summary

This study tests whether an 8-week home-based breathing exercise called Inspiratory Muscle Strength Training (IMST) can reduce dementia risk in adults aged 60-80. Researchers will measure changes in blood pressure, thinking skills, mood, and sleep quality. The goal is to see if this simple, drug-free approach is practical and effective for older adults.
