Liver Flap / Asterixis questions

Hello my name is Donna and I'm new to the forum . My mother is on peritoneal dialysis due to kidney failure and she's been going down hill for a couple of months and the Doctors have just told us they think she has Liver flap / Asterixis so I have been trying to research and get more information . Everything I have found online about this condition says that the " jerks " are in the hands so my question is does anyone know if this can cause jerks all over her body ? My mom jerks all over not just her hands and the jerks are so bad at times she has actually fallen down 4 times due to her legs jerking because she says when it happens its like she has no control over her legs and they just go out from under her . She uses a walker but she continues to weaken daily and she's now to the point she can hardly get out of bed and the Doctors are telling us it's due to the Liver Flap . Can anyone give me some information on this disorder because I'm not convinced that this is her problem . Thanks in advance

Thanks PPM guy for replying and I apologize for it taking me so long to reply back but things have been crazy for me lately because Mom is not doing good at all . I am so confused about this " new " so called diagnosis and talk of Liver Flap ...as of now sadly I think my Mom has given up on life , she's 71 years old and been on dialysis for a year and she's been in and out of the hospital 11 times in the past year so it's been a long hard year for her and my family . My sister and I have been doing her dialysis at home " peritoneal dialysis" because we could never get a graft to work for hemo-dialysis due to her veins being so small . We ran out of options and started doing dialysis at home which was much easier on her . But she has been going down hill for the past few months and is so weak at this point ,we have no other options unfortunately but to put her in a nursing home for what they say will be long term rehab. She is so weak we can no longer help her at home without risking a serious fall etc... They just placed the temporary tunnel cath in her neck so that they can't do hemo -dialysis while she is in the nursing home because they do not do peritoneal dialysis at any of the nursing homes ...which is a HUGE infection risk but we have not other options . The doctor tells us that they think she has this liver flap syndrome due to the way her body is jerking but at no time told us this was end stage liver disease on top of everything else we are dealing with . I don't understand how they can tell us something like that and say they are going to try changing some of her medications and taking her off some as if that would be a cure all to this jerking issue / liver flap but at no time have they told us her liver is shutting down . Everything I have been able to read so far has talked about the hands jerking but nothing about the whole body jerking and Mom is doing it all the hands and legs etc.. so bad that she cant walk due to her legs jerking and causing her to fall .Mom is not a candidate for transplant of any kind due to her age and other health problems so I'm afraid if the Doctors are correct about the Liver flap issue and it's end stage liver disease then this is NOT GOOD at all . Really helpless at this point it's hard watching the woman who has been by my side from day one of my life basically dying and their is nothing I can do to help her . Anyway thanks for the reply ...
