Study Details

Brief summary:

There is a great unmet clinical need for improved screening for MHE in patients with cirrhosis. We will demonstrate that the Flicker-App can be used in clinic as well as at home by patients with cirrhosis to measure CFF, a proven screening test for MHE. We will optimize the protocol, software, and hardware of the Flicker-App to create a product appropriate for production and distribution to patients
