Alzheimer's Disease

A progressive neurodegenerative disease and the most common cause of dementia, accounting for 60-80% of cases. Alzheimer's disease causes gradual decline in memory, thinking, and reasoning skills, eventually affecting the ability to perform everyday activities. The condition progresses through stages—early, middle, and late—with varying impacts on cognitive and functional abilities. For digital accessibility, design considerations include simplified interfaces, consistent navigation, reduced memory demands, personalized content using familiar images and sounds, and support for caregiver-assisted or proxy use. People with Alzheimer's can remain socially engaged and express themselves meaningfully, particularly in early and middle stages, challenging deficit-focused technology design.
