An 86-year-old patient with Alzheimer's disease was admitted to the hospital with dehydration. Her daughter states that her mother has been very confused and combative lately. Explain why the patient likely developed dehydration
What will be an ideal response
One of the simplest mechanisms for maintaining fluid balance is the thirst mechanism. Normally, when a person is thirsty, he or she drinks because the thirst center in the hypothalamus is stimulated. In this patient's confused and combative state, she is probably refusing or forgetting to eat or drink, thereby developing dehydration.
