My husband was diagnosed over a year ago, and was nearly in a coma then. He had symptoms for years but there wasn a definite diagnosis. He is nearly 70 and has had numerous other health issues too. He can barely function at times and appears grandchild. He seems to almost be sleeping while half conscious. His movements are unbearably slow. It has been Life changing. He takes l lactulose but not regularly. He is just wiped out. Help.
