Abstract
Introduction and Objectives: Dementia, particularly Alzheimer's disease, is characterized by symptoms such as memory impairment, language difficulties, behavioral changes, and challenges in performing daily activities. In the early stages, the disease leads to a decline in cognitive functions, especially working memory and cognitive flexibility. Given the impact of these two components on patients’ quality of life, non-invasive interventions such as auditory stimulation have gained attention as innovative approaches.
Materials and Methods: This study aimed to examine the effect of auditory brain stimulation on working memory and cognitive flexibility in adults with Alzheimer's disease. The research followed a quasi-experimental design with a single-group pretest-posttest format. The statistical population consisted of all adults with early-stage Alzheimer's disease in Tabriz in 2023. Using purposive sampling, 15 patients with a mean age of 60.93 were selected from neurology clinics, following confirmation by a neurologist. Data were analyzed using the independent t-test. Results: The results of the within-group analysis showed a significant improvement in participants' performance on the Wisconsin Card Sorting Test (t(14) = 2.64, p = 0.019), and a substantial increase in the Block Design test (t(14) = 5.55, p < 0.001). However, the change in the Digit Span test was not statistically significant (t(14) = 0.82, p = 0.424). Conclusion: The findings of this study suggest that auditory stimulation can serve as an effective non-invasive intervention in slowing the progression of Alzheimer's disease and improving patients' quality of life. These results may support the broader use of sensory-based interventions in treating cognitive impairments related to dementia.
