This scoping review examines the effects of touch/massage on agitation and stress in hospitalized geriatric patients suffering from dementia. This intervention is multidimensional, at the edges of medical neurosciences, nursing sciences, and the social sciences. This review is primarily supported by a biological model of social relations, describing the interconnection between cognition, affect, and endocrine aspects of attachment modes. It is also guided by nursing sciences conceptualizations, which anchor touch/massage in the heart of nursing practice. The importance of touch/massage and its emotional regulation capacity is discussed in the light of these conceptualizations. The need for this kind of contact in geriatric inpatients with dementia appears to be related to sensory loss and to a lack of emotional and social contacts. Evidence of the benefits of touch/massage is summarized and indicates that this intervention is sometimes difficult to provide for agitated patients. Finally, proposals are made to develop a scientific agenda in clinical settings in order to continue the development of evidence and thus contribute to better informed nursing practice.
