Non-pharmacological treatment of color, illumination, type, and texture of environmental materials on people with dementia Alzheimer type

This interdisciplinary article is conducted to investigate the effects of the three (four???) components of color, illumination, type, and texture of environmental materials on people with dementia of Alzheimer's type with a neuropsychological approach. The aim of this article is to respond to the environmental needs of these patients to reduce cognitive impairment, behavioral disorders and improve their daily living activities. is conducted by inductive qualitative content analysis method based on narrative review from 1970 to 2017. Down and Black checklist for quality assessment is used to include interventional research. while color and illumination are classified into four categories, type and texture of environmental materials are categorized into two groups. cross-case analysis and comparative analysis showed that type, color, temperature, and illumination have non-pharmacological treatment on people with dementia and Alzheimer disease. Also, type and texture of environmental materials have an important role in their desired and / or undesirable mental and visual perception, rather than on their physiological state. The synergistic effect of color, illumination, type and texture of environmental materials can enhance the semantic environmental perception for people with dementia and Alzheimer's.
