According to Krause's Therapeutic book, the condition of Alzheimer's can cause decreased food and fluid intake due to impaired hunger / thirst perception and forgetfulness. This leads to overall malnutrition and dehydration. The clinical aspects of dehydration can exacerbate the problems of food and fluid intake already caused by Alzheimer's. Clinical signs of dehydration include increased confusion, lethargy, falling episodes and poor skin turgor. At admission, the patient had BUN levels of 40 mg/dL and serum sodium was 151 mEq/L. Elevated BUN and serum sodium also point toward clinical dehydration.
