An innovative intervention for the treatment of cognitive impairment–Emisymmetric bilateral stimulation improves cognitive functions in Alzheimer’s disease and mild cognitive impairment: an open-label study
Bibliographic record
Abstract
BACKGROUND AND AIMS: In the last decade, the development of different methods of brain stimulation by electromagnetic fields (EMF) provides a promising therapeutic tool for subjects with impaired cognitive functions. Emisymmetric bilateral stimulation (EBS) is a novel and innovative EMF brain stimulation, whose working principle is to introduce very weak noise-like stimuli through EMF to trigger self-arrangements in the cortex of treated subjects, thereby improving cognitive faculties. The aim of this pilot study was to investigate in patients with cognitive impairment the effectiveness of EBS treatment with respect to global cognitive function, episodic memory, and executive functions. METHODS: Fourteen patients with cognitive decline (six with mild cognitive impairment and eight with Alzheimer's disease) underwent three EBS applications per week to both the cerebral cortex and auricular-specific sites for a total of 5 weeks. At baseline, after 2 weeks and 5 weeks, a neuropsychological assessment was performed through mini-mental state examination, free and cued selective reminding tests, and trail making test. As secondary outcomes, changes in behavior, functionality, and quality of life were also evaluated. RESULTS: After 5 weeks of standardized EBS therapy, significant improvements were observed in all neurocognitive assessments. Mini-mental state examination score significantly increased from baseline to end treatment (+3.19, P=0.002). Assessment of episodic memory showed an improvement both in immediate and delayed recalls (immediate recall =+7.57, P=0.003; delayed recall =+4.78, P<0.001). Executive functions significantly improved from baseline to end stimulation (trail making test A -53.35 seconds; P=0.001). Of note, behavioral disorders assessed through neuropsychiatric inventory significantly decreased (-28.78, P<0.001). The analysis concerning the Alzheimer's disease and mild cognitive impairment group confirmed a significant improvement of cognitive functions and behavior after EBS treatment. CONCLUSION: This pilot study has shown EBS to be a promising, effective, and safe tool to treat cognitive impairment, in addition to the drugs presently available. Further investigations and controlled clinical trials are warranted.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
