My Dad is alert, but is having trouble expressing his thoughts in a completely coherent manner. He will start to express a thought, but the right word won t come to mind and makes math problems a little more convoluted than necessary. He feels well physically overall, but mind feels a little fuzzy. He has had these symptoms for a mo. or more-off & on. His BP is WNL, occ. very sl. dizziness. His eyes can follow the tracking of my finger and he has no prob. lifting both arms and holding position. He is somewhat dehydrated, but got him to drink lots of water and eat melon tonight. He knows everyone s name and birthdates.
