Case Report

Alzheimer’s disease is the most common form of dementia characterized by cognitive impairment decline with disease progression. Various non-pharmacological interventions have been used to delay cognitive deficits and minimize functional impairment. Cognitive intervention therapy has recently been in the limelight as another treatment method for dementia. However, it is also true that the efficacy of the cognitive intervention for dementia is underestimated because there is no clear evidence on the methods, contents, and targets of it. Additionally, there is no sufficient evidence yet about the optimal duration of cognitive intervention therapy for dementia. In this case, we present a patient with dementia who has been receiving cognitive intervention therapy for 10 years.
