Dementia in Africa: Virtual reality app aims to break stigma

An estimated 4 million people across Africa live with dementia, according to the latest figures by Alzheimer's Disease International. It's an incurable condition that affects people's mental abilities, including memory.

VR Revival is a health technology start-up aiming to improve the quality of life and care for those with dementia with a new virtual reality app.

The company's British-Gambian founder, Mansata Kurang, explains how she hopes the app will help sufferers and those who care for them.
