Although people with cognitive impairment have a higher risk of getting lost when they go out, staying at home for long periods of time can make them more susceptible to cognitive decline. Instead, caregivers should take them out more often to maintain a sufficient social life. Before going out, caregivers can use their cell phones to take photos of what the elderly are wearing on that day as a record, so that they can more easily seek help from passers-by or the police in case they get lost. In addition, a Bluetooth tracker can be placed in the elderly's handbag so that they can use their cell phone to track their location when necessary. Caregivers should also wear bracelets engraved with the name and telephone number of the emergency contact person to facilitate the recovery of elders. When going out with the elderly, avoid going to crowded places and walk at the same pace as far as possible. Do not go out for too long, so that they will not be in a hurry to go home and get lost easily.
