Abstract (original English)

Background Stem cell therapy (SCT) is increasingly recognized for its potential in managing cognitive impairment, particularly that of dementia. The application of SCT aims to restore cognitive functioning in people living with dementia. Beyond pre-clinical studies, several clinical trials have evaluated specific stem cell (SC) types for their efficacy in treating dementia. Aims & objectives To assess the status and efficacy of pre-clinical and clinical studies utilizing SCs as a therapeutic approach for dementia. Methods A systematic review was conducted using two electronic databases: MEDLINE and Embase. We reviewed studies on the application of SCs in dementia, focusing on the following aspects: Animal models used in pre-clinical studies, tissue sources of SCs and donor species, and administrative routes and outcome assessments. Included papers comprised randomized control trials (RCTs) and original studies, while those involving adjuvant therapies for dementia were excluded. Quality assessment criteria included relevance to the research question, type of SCs, stage of SC transplantation, duration and route of administration, methods for outcome assessment, and the total number of animals implicated. Results A total of 32 papers were included, encompassing 21 clinical trials and 11 preclinical studies. The preclinical studies employed various transgenic animal models to eval
