Bedrooms for the elderly with dementia should have suitable temperature and humidity and fresh air. Ventilation for 20~30 minutes every morning and evening to reduce pathogenic microorganisms in indoor air.
Because the eyesight of the elderly has declined, for example, the light intensity needed by 80 years old is three times that of 20 years old. Therefore, the living room of the elderly should be decorated with adequate lighting. The layout of the room should also be simple, and the furniture should not be changed frequently to facilitate the elderly to walk and identify. At the same time, bright, pleasing and warm signs can be used to distinguish the functions of each room in the living room and help the elderly with poor memory find the bedroom, kitchen and bathroom. Large calendars and wall clocks at home can promote the sense of time and orientation of the elderly.
The elderly with dementia need the help of others to avoid danger because of the loss or reduction of their cognitive, judgment and memory abilities. Hot water bottles, electric socket boards, knives, scissors, glassware and other items that may cause harm to the elderly at home should be placed in hidden and inaccessible places. The kitchen with gas tanks should be locked, and the floors in the living room and corridor must be non-slip and wax-free. Avoid reflecting light and geometric decoration on the floor to meet the needs of the elderly, so as to avoid fracture caused by falling or danger caused by blurred vision. Old people will wander and get lost because of mental retardation, poor memory and loss of spatial positioning ability. In order to facilitate the search, the clothes worn by the elderly should be marked with their names, ages, addresses and telephone numbers.
