PMID 40275307WHAT IT FOUND
Alpha-wave neurofeedback combined with working memory training ranked best for working memory.
Alpha-wave neurofeedback alone ranked best for episodic memory. These findings apply only to healthy adults, not patients with memory disorders.
Key findings
01The combination of alpha neurofeedback and working memory training was ranked as the most effective intervention for improving working memory.
02Alpha neurofeedback alone was ranked as the most effective intervention for improving episodic memory.
03The study included only healthy participants, excluding those with neurological or psychological disorders.

What it does not show
The study included only healthy participants, so results cannot be generalized to clinical populations with memory impairments. There was significant inconsistency in the statistical network between direct and indirect comparisons, particularly for working memory. Training parameters such as session duration and frequency were not standardized or analyzed, making it unclear what dose of neurofeedback is optimal. Many of the combined interventions (like alpha plus working memory training) were based on a small number of studies.

The easy way to misread this
Do not interpret the high ranking of alpha neurofeedback combined with working memory training as proof that neurofeedback itself is the active ingredient. The data shows that the combination with cognitive training was superior, but it does not isolate the specific contribution of the neurofeedback component from the cognitive training component.
