What advice is given to the patient’s family?

The patient’s family should be instructed about their patient care and safety. The patient should not be irritated by using words that makes him angry like disabled, useless, worthless and insignificant. Other measures taken to protect him from harm like removing sharp objects, locking doors properly, stairs safety, secure electronic devices and avoiding chances of slips and falls. It is good to benefit from sharing of social health organizations, which can provide home care and encourage them to visit AD patient at home, for proper follow-up and health assessment with monitoring the patient’s condition and providing training for the patient’s family on how to take care of the patient. Recent studies show new information about medications that are promising for AD which need further analysis before use, so we should not stop hoping to find a cure of the disease soon.
