Interventional Study.
No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
This record has not been graded across any dimension yet. Treat the label above as provisional and read the source.
What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT04599764). This is a study registration, not published results. Lead sponsor: Anhui Medical University. Recruitment status: COMPLETED. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 60 participants (ACTUAL). Conditions: Transcranial Direct Current Stimulation, Functional Magnetic Resonance Imaging, Early Alzheimer's Disease. Interventions: OTHER: HD-tDCS; OTHER: computer-based cognitive training; OTHER: Sham tDCS; BEHAVIORAL: Control cognitive training. Primary outcome measures: Changes assessed by Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) , changes from baseline at 14 days and 12 weeks post-treatment. Brief summary: This completed randomized trial evaluated the clinical and neural effects of high-definition transcranial direct current stimulation (HD-tDCS) combined with computerized cognitive training in patients with Alzheimer's disease. Participants were assigned to active HD-tDCS plus computerized cognitive training, computerized cognitive training control, or active HD-tDCS control. The study assessed whether combined neuromodulation and cognitive training produced greater cognitive and clinical benefit than either component condition, and whether treatment-related benefit was associated with changes in brain network organization.
