Longitude Prize on Dementia

Transforming assistive technology to preserve independence and dignity

What was the Longitude Prize on Dementia?

The £4.4 million Longitude Prize on Dementia was a landmark global initiative driving the creation of personalised, AI-powered technologies co-created with people living with early-stage dementia to help them maintain independence at home.

Funded by Alzheimer’s Society and Innovate UK, and delivered by Challenge Works, the challenge incentivised innovators to develop tools that adapt to a user’s changing needs as their condition progresses, enabling them to stay active, safe, and live fulfilled lives.

The Challenge: Extending independent living in the home

Dementia is a leading global health crisis, with 1 in 3 people born today expected to develop the condition. As symptoms progress, everyday tasks – from recognizing household objects to following multi-step routines – become increasingly difficult. This leads to a loss of autonomy, heavy strain on unpaid carers, and premature entry into long-term residential care.

The Solution: Rather than relying on passive monitoring or reactive care, the prize challenged global teams to build proactive, adaptive technologies that learn user habits, bridge cognitive gaps, and guide individuals through daily activities; designed hand-in-hand with people living with the disease.
