Mobile health uses technology like smartphones and AI to improve healthcare access, efficiency, and patient empowerment. AI can help with smart diagnostics, clinical decision making, disease prevention and management, and administering real-time treatment. For example, AI may be able to detect early signs of Alzheimer's from data and spot health issues for patients by monitoring their symptoms, activities, moods and diet. However, using AI in healthcare faces challenges regarding responsibility for mistakes, lack of large clinical datasets, need for common sense and lack of regulations. With proper development and oversight, mobile health and AI could help address gaps in accessing quality healthcare.
