Wernicke-Korsakoff Syndrome

So I've spent most of my day on the internet researching Wernicke-Korsakoff Syndrome. It is also called wet brain or Korsakoff's psychosis.  This is the condition that my mother-in-law has been diagnosed with.  It is caused by an extreme thiamine deficiency that comes from lack of food & chronic alcohol abuse.  Basically it means that she has extreme memory loss, psychotic episodes & a major loss of coordination.  Although this condition is reversible in some cases with the administration of IV thiamine supplements & abstinence of alcohol, she refuses to give up her vodka tonics, so will likely never recover.  Very depressing.  There is basically nothing we can do for her besides make sure that she isn't left alone, so she doesn't burn the house down or something.
