Requesting fNIRS Datasets for Alzheimer’s Research"

Hello,
I am a master’s student in Biomedical Engineering working on a thesis exploring the use of fNIRS in Alzheimer’s research, specifically focusing on wavelet analysis. I am looking for publicly available datasets or guidance on accessing fNIRS data related to Alzheimer’s disease. Any recommendations, shared datasets, or advice would be greatly appreciated.

Thank you for your help!

Best regards,
