1. Early Diagnosis and Detection

• Medical Imaging: AI can scan X-rays, MRIs, and CT images faster and sometimes more accurately than doctors.

• Disease Prediction: AI models predict risks for illnesses like heart disease, diabetes, or cancer before symptoms appear.

• Wearable Devices: Smartwatches track heart rate, sleep, and oxygen levels, alerting doctors to potential issues early.

👉 Benefit for seniors: Early detection of conditions like dementia, heart disease, or stroke can greatly improve outcomes.
