Advancing liver disease can affect the kidneys. Sometimes the liver transplant will bring the kidneys back to health. Sometimes patients require dialysis until liver transplant.
Never give up! My doctors and my family did not give up on me. I had a liver and kidney transplant 10 years ago at age 60.
Sending positive thoughts.

@tgshomes I'm sorry to hear your Dad is in hospital. I personally never had kidney issues but there are others here who can address this better. Be patient with your Dad even though it is scary for you. Being in his place I remember feeling extremely frustrated not being able to answer the simplest questions correctly. I had nightmares about this. Eventually things will come back to him but maybe not quickly. Just keep giving him the correct answer. Patience is the key right now.

@tgshomes I’m sorry your dad is in the hospital again.
I did recognize people I knew, but I didn’t know the year, who was president and a slew of other things. As you may start noticing, HE symptoms tend to run the gamut. I think everyone has confusion but many other symptoms vary. I am a very non-confrontational, non-aggressive person, but I tried to hit my husband during one episode. That was before I had a diagnosis so we didn’t know what was causing my behavior. My daughter (she’s an adult) was present and horrified. I think for a long time after that she was actually upset with me.

@gaylea1 I do have some short-term memory problems but I assumed that was due to getting older. Interesting to think it could be related to past HE or perhaps to medications.
