Alzheimer's dementia considerably affects the life of the person who has it, the family and the environment that surrounds it. Symptoms are evident in the cognitive, motor and psychosocial sphere and in how people with dementia process stimuli. Objective: To review the principles and methods of sensory integration and its influence on the central nervous system, to be applied to older people with Alzheimer-type dementia. Method: The theoretical foundation and the application of sensory integration are exposed through the five stages of the approach. Results: The first stage aims to alert sensory systems and focus attention through an olfactory stimulus, in order to start the second stage, in which stimulation on the proprioceptive and tactile system becomes relevant. In the third stage, perceptual integration favors the conservation of visuospatial skills aimed at cognition, an area that is worked on in the next stage. Finally, the gustatory stimulus and the relaxation that is given lead to the establishment of interpersonal relationships and the acquisition of adaptive behaviors. Conclusions: The use of the sensory integration approach in people with Alzheimer's dementia requires more research through experimental studies; also a series of elements related to activities, rigor, self-organization, adaptation of the environment, creativity and motivated participation of the subjects and the therapist.
