A PRISMA-guided systematic review found that while patients with idiopathic Parkinson's can learn to self-modulate neural signals via fMRI, EEG, or DBS neurofeedback, consistent improvements on validated clinical or behavioral outcomes are lacking due to small samples and methodological…
Indicates neurofeedback has mechanistic plausibility and translational potential but currently insufficient, underpowered clinical evidence—prioritizing larger, standardized trials and standardized effect-size reporting could determine its real therapeutic value for PD.
