Effects of interventions on dementia patients and caregivers: A systematic review

The dimensions of the problem are not only felt by the patient but also by the caregiver who cares for him. The selection of the right intervention is needed to overcome the problems of patients and caregivers. The purpose of this study was to disseminate the types of interventions, psychological effects on patient dimensions, and psychological effects on caregivers. The study used guidelines from the PRISMA 2020 guidelines to identify and critically review relevant studies. The study was conducted using electronic databases, including Scopus and PubMed, using the keywords “mental” or “psychological” AND “intervention” AND “Dementia” AND “caregiver, and it was limited from 2020-2025. The risk of bias was measured using the Cochrane risk-of-bias tool for randomized trials (RoB 2). There were 543 articles, and 12 were relevant to the research objectives. The findings showed that there were 12 types of interventions, with 6 interventions only assessing the effects on caregivers and 6 interventions looking at the psychological effects on patients and their caregivers. Interventions provide positive benefits to patients and caregivers. Combining more than one intervention is recommended to get better effects.
