Alzheimer’s disease is a degenerative disease of the central nervous system and there is no particularly effective clinical treatment for it. Patients in the middle and late stages of Alzheimer’s disease who are incontinent should have urinary catheters or regular bowel movements to avoid urinary tract infections, and nutritional support should be given to patients with Alzheimer’s disease, such as protein and vitamins. A gastric tube can be placed if the patient has difficulty eating. If necessary, an acetylcholinesterase inhibitor, such as donepezil hydrochloride, can also be used. Patients with advanced Alzheimer’s disease mostly suffer from malnutrition or life-threatening secondary infections. The main care for Alzheimer’s disease patients with incontinence is to improve nutrition and to turn and tap the back more often to avoid infections.
