Background: Alzheimer's disease (AD) with its high burden on disability is known as one of the critical public health issues worldwide. Hence, providing comprehensive care and effective symptomatic treatment are becoming a challenge for many healthcare systems. Quality of life (QOL) has been identified as an important indicator to develop holistic care for people living with AD since it reflects treatment response, the progression of AD, and activities of daily living. This study aimed to identify research trends and landscapes as well as important factors in QOL studies in the field of AD. Summary: English research was extracted from the online database Web of Science to analyze research publications' growth rate and content on AD and QOL. VOSviewer was used to visualize the correlations between terms in titles and abstracts. Research topics were created using Latent Dirichlet Allocation of abstracts' content and disciplines. Major landscapes in the QOL assessment included care and treatment for AD in epidemiological studies and clinical trials. Besides, most studies were conducted in highincome countries, such as the USA or the United Kingdom. Findings of our study also identi-fied a lack of contextualized factors and research gaps in terms of QOL among individuals with AD. Key Messages: Further studies should be conducted taking an effort to assess QOL among demented patients as well as advancing knowledge, attitude, and practice among family caregivers. diagnosis to reduce depression, agitation, and anxiety caused by the disorder, as well as behavioral issues, such as delusions, that can accompany AD.Some limitations should be acknowledged. The search was conducted via the WOS, and only English reviews and articles were included. However, there is a high possibility that a large number of papers for analysis are indexed in other databases, including PubMed and Scopus. Hence, our results should not be generalized to all types of publications. Further studies might be available to conduct a systematic review and meta-analysis of how QOL can shed light on the effect of treatment or interventions regarding AD.
ConclusionUsing scientometric analysis, the global academic trends and interest concerning QOL and AD have been illustrated. By using LDA, our results highlighted that QOL of caregivers has received attention from scientists. Further longitudinal studies are required to identify empirical evidence for developing new interventions for AD, assessing QOL in patients with AD as well as improving knowledge and support for caregivers.
