When a person living with dementia experiences sensory stimulation, that information is processed in the limbic system of the brain, influencing their emotions in the amygdala and memories in the hippocampus. Therefore, when positive stimuli is used, it can influence the person to feel positive feelings and memories, ultimately affecting their behaviors. Aromatherapy provides support using olfactory stimulation. Inhalation of essential oils provides an entryway to the limbic system, promoting positive feelings and memories. When used, this can influence a sense of calm, boost in mood, etc., influencing productive behaviors.
