Akili has designed a game called Evo to help detect Alzheimer's disease. Evo tests cognitive interference and distraction, which is important for daily functioning. Players steer an alien down a river on their phone or tablet while tapping the screen in response to distractions. Performance data is collected and compared to standardized data from normal and Alzheimer's patients to potentially provide a more cost-effective diagnosis than a PET scan. Evo aims to provide an assessment similar to Cog Cubed's game for detecting cognitive impairment.
