The patient's sense of security is closely related to behavioral and emotional expressions. When the patient feels uneasy, there is an increased chance that he or she will exhibit behaviors such as wandering. On the other hand, if the patient feels safe and secure in the environment, the chances of behavioral expressions will be reduced. Therefore, family members and caregivers should put more effort into improving the patient's living environment. The design should be in line with the patient's personality and preferences. Family members can review the patient's previous home environment and the patient's preferred colors, and then put these elements into the design. Some photos of friends and relatives and favorite things can be placed in the decoration.
