He came home, has gone for modified barium test on throat. Results so far are one side of vocal chord is paralyzed so when he swallows clear liquids go directly into lungs. So he definitely needs thickened liquids. His memory only includes clear liquids. If I walk out of room he will pour himself a drink of iced tea or whatever he can find to drink. I need to hide all drinks so he can't find them. Has anyone dealt with this type of situation and how did you deal with it? Thanks.
