Summary

This study is developing a web-based app that analyzes how you speak and remember things to quickly detect early cognitive problems like dementia or Alzheimer's. Researchers will enroll 500 people (healthy adults over 45 and those already diagnosed with mild cognitive impairment or dementia) to test the app at home. The goal is to make early detection easier and faster, so people can get a proper diagnosis and treatment sooner.
