An open dataset for cognitive training effects on brain and cognition in older adults with subjective memory decline

Neuroimaging findings suggest that older adults with subjective memory decline (SMD) demonstrate some neurodegenerative brain changes and have high risk of developing dementia, but relatively little is known about the effectiveness of interventions for SMD. This study aimed to examine the effects of cognitive training on resting-state brain activity in SMD.The image data was obtained using a 3-Tesla Siemens Trio scanner. After MRIQC screening and withdrawal of some subjects, the final resting-state functional connectivity analysis included a total of 15 subjects in the control group (M=71.53 ± 6.15 years old; 6 males), training group of 20 (M=74.10 ± 3.48 years old; 6 males).
