Dementia, which means loss of mind, is characterized by chronic, usually progressive, impairment in at least two of the cognitive functions such as speech, perception, calculation, judgment, abstract thinking and problem solving. In the literature, it is emphasized that dementia is directly related to age. In particular, studies have shown that the risk of developing dementia increases 6.60 times in individuals aged 90 years and older. This result draws attention to the fact that dementia is an important public health problem for the aging population in our  country in particular and in the world in general. In addition to age, studies in this field have also revealed that the risk of developing dementia is higher in women, individuals who have the epsilon 4 genotype of Apolipoprotein E, have a history of Alzheimer's disease in a firstdegree relative, have a history of hypertension, diabetes, hypercholesterolemia, are obese, smoke and drink alcohol, have a folate-poor diet and consume a lot of coffee. While screening for early detection of dementia is important, resistance exercise, five-component care (pain management, oral care, education program for doctors and nurses, systematic and early communication with families and nurse follow-up) and Namaste care have been found to improve quality of life, well-being, ability, sleep and activity in patients with dementia. However, the limited number of studies utilizing the developing technology while caring for dementia patients shows that there are deficiencies in this field. Therefore, there is a need for new and more technology-based studies that will keep the independence of the individual at the optimum level.
