About

Alzheimer's disease (AD) is the most common form of neurodegenerative disorders leading to dementia. Currently, there has been no effective pharmacologic therapy for this disease. Electroencephalogram-based neurofeedback is considered as a potentially treatment strategy. In this project, the investigators aim to investigate the effectiveness of neurofeedback therapy on cognition for individuals with subjective cognitive decline (SCD). Participants will receive electroencephalogram-based neurofeedback therapy once a day for successive five days. Then, the investigators will evaluate the changes of memory function between baseline and post-therapy visits.

Full description

Currently, there has been no effective therapy for Alzheimer's disease (AD). Electroencephalogram-based neurofeedback is now considered as a potentially intervention and may positively affect cognitive function for patients with AD. However, there are few existing studies involving the role of neurofeedback on cognition for subjective cognitive decline (SCD).

Fifty participants with SCD will be recruited in this clinical trial. At baseline, neuropsychological tests are conducted. Participants will receive electroencephalogram-based neurofeedback therapy once a day for successive five days. After that, the investigators will evaluate the changes of memory measures, which is the primary outcome.
