Title : Digital therapy for mitigating dementia and mild cognitive impairment: A review of efficacy and applications
Abstract:
Dementia and mild cognitive impairment (MCI) are progressive neurodegenerative conditions that significantly affect memory, executive function, and daily living. As global populations age, innovative, accessible interventions are increasingly important. Digital therapy, which includes computer-based cognitive training programs, mobile health applications, and virtual reality environments, offers a promising, scalable approach to support cognitive health in older adults. This review explores the efficacy of digital therapy in mitigating cognitive decline associated with dementia and MCI. Studies have demonstrated that targeted digital interventions can enhance memory, attention, processing speed, and executive function through repeated engagement and personalized difficulty adjustment. Moreover, digital platforms often incorporate real-time feedback, gamification, and adaptive learning, which can improve adherence and motivation. Emerging evidence also suggests that digital therapy may contribute to neuroplasticity, helping preserve brain function even in early stages of cognitive impairment. In addition to cognitive benefits, digital tools often provide remote monitoring capabilities and caregiver support, broadening their impact on holistic dementia care. However, challenges remain regarding accessibility, digital literacy, and the need for long-term clinical validation. In conclusion, while not a replacement for pharmacological or in-person therapies, digital interventions represent a valuable adjunct in managing MCI and early dementia. Further longitudinal and large-scale randomized controlled trials are necessary to establish standardized protocols and maximize therapeutic outcomes.
