**6.2 Indications for testing**

There is no consensus on patients to test for MHE. Some physicians recommend screening of all cirrhotic patients. However, testing should be completed in patients at risk (**Table 2**) for MHE such as, cirrhosis or porto-systemic shunts [5]. Special attention should be given to active drivers, patients handling heavy machines or reporting decline in work performance [75, 76].
