BCIwiki (bciwiki.com) — Authors at Mexico’s National Rehabilitation Institute and the Center for Research and Advanced Studies of the National Polytechnic Institute reviewed BCI cognitive rehabilitation in Bioengineering on October 19, 2026, finding that randomized clinical trial evidence remains limited.
The narrative review covers Alzheimer’s disease, Parkinson’s disease, mild cognitive impairment, cerebrovascular diseases and ADHD. Existing studies report cognitive improvements in mild cognitive impairment, stroke and ADHD, supporting feasibility as a complementary therapy.
All reviewed applications use non-invasive EEG. Invasive and other non-invasive approaches remain insufficiently assessed. Multiple sclerosis, traumatic brain injury, brain tumors, infectious diseases, schizophrenia, autism spectrum disorder, and drug- or toxin-related cognitive impairment fall outside the review’s scope.
The authors call for training designed around specific cognitive functions and stronger clinical evidence to move beyond demonstrations of feasibility toward rehabilitation use.
