At HLTH 2025, Ian Khan sits down with Peter Kallestrup, co-founder and CEO of i-Function, to discuss cognitive health. i-Function develops computerized cognitive and functional-skills assessment used to detect and address cognitive impairment, including early signs of Alzheimer's. Kallestrup shares how technology-based assessment can measure real-world function and support earlier intervention. The conversation explores how digital tools can help address cognitive decline in an aging population.
