Dementia affects a growing number of people in the United States, largely driven by an aging population. Recent estimates suggest that more than 6 million Americans aged 65 and older are living with Alzheimer’s disease, the most common form of dementia. The total number of individuals affected by all types of dementia is expected to rise significantly in the coming decades as life expectancy increases. Dementia is one of the leading causes of disability and dependency among older adults, placing a heavy emotional and financial burden on families and the healthcare system. Annual care costs in the U.S. exceed hundreds of billions of dollars when including medical care, long-term care, and unpaid caregiving.
Artificial intelligence is increasingly being explored as a tool to improve dementia care. AI models can help detect early cognitive decline through analysis of speech patterns, memory tests, and brain imaging. Machine learning systems can also predict disease progression by analyzing electronic health records and lifestyle data. In clinical settings, AI can support doctors by improving diagnostic accuracy and identifying high-risk patients earlier. AI tools can assist patients with daily tasks, provide safety alerts, and improve quality of life while reducing caregiver burden significantly over time overall.
