Minimal hepatic encephalopathy impairs fitness to drive
Christian Wein, Horst Koch, Birthe Popp, Gerd Oehler, Peter Schauder – 27 February 2004 – It has been suggested that the ability to drive a car is impaired in patients with cirrhosis of the liver and minimal hepatic encephalopathy (MHE). However, the only study using an on‐road driving test did not reveal such an impairment. In a prospective controlled study, we evaluated patients with cirrhosis of the liver for MHE and the ability to drive a car. MHE was diagnosed using three psychometric tests: Number Connection Test Part A, Digit Symbol Test, and a Complex Choice Reaction Test.
