This is a test of mental speed and flexibility that was first described in 1929 in Germany and then published in English by Stroop in 1935.
The Stroop test have been administered on paper, computers and on apps.
EncephalApp is a series of applications designed to evaluate patients with liver disease; the first of which is a Stroop task.
It has neutral and incongruent stimuli only.
Stroop tests involve correctly identifying the color that the stimuli are presented in apresenting three kinds of stimuli
It has been found in selected patients to be predictive of minimal hepatic encephalopathy (MHE) in two study centers.
This app will be available for download for free but the terms of service are noted above. These must be followed. The screen cap on the left shows the initial face of the app which has a "Settings" wheel that is explained further down.
Current strategies for testing cognitive dysfunction are difficult and not very easily available or practiced in clinic
The app is a shorter method to screen and diagnose patients with covert/minimal hepatic encephalopathy (CHE/MHE)
“The EncephalApp Stroop App has been evaluated for the diagnosis of MHE/CHE and the prediction of Overt HE development in four centers till date. These centers are Virginia Commonwealth University, Richmond VA Medical Center, University of Arkansas Medical Center and Cleveland Clinic. The experience shows that this is a useful method to diagnose MHE/CHE. Three peer-reviewed papers and five abstracts have been published with EncephalApp (Bajaj JS et al Hepatology 2013, Bajaj JS et al. Clinical Gastro Hep 2015 and Allampati et al Am J Gastro 2015 in press).
