Actually, I was looking for a continuation of an answer from the previous page. But since you re here... By bro-in-law was a long term alcoholic and has acute cirrhosis of the liver. His brain ammonia levels have been reduced back to relatively low levels, and yet he s experiencing increasingly difficult cognition, just barely ambulatory, confusion, extremely sluggish, depressed, and so on. His GP recently prescribed diazepam for his anxiety and insomnia. My guess is that he may be abusing them, but is there a correlation between diazepam and the appearance of hepatic encephalitis?
