Résumé du contexte et des objectifs généraux du projet

Acquired brain injury (ABI) is a leading cause of long-term cognitive disability in Europe, with attentional deficits representing one of the most frequent and functionally disabling consequences. Despite their impact on autonomy, return to work, and quality of life, available cognitive rehabilitation interventions often show limited effectiveness and poor patient engagement. At the same time, non-invasive, technology-based interventions such as EEG neurofeedback have gained increasing attention, but robust clinical evidence supporting their efficacy, feasibility, and added value over standard rehabilitation remains scarce.

Within this context, the NeMoRe project aimed to investigate EEG-based neurofeedback as a novel, patient-centered cognitive rehabilitation approach for ABI. The overarching objective was to validate neurofeedback as a safe, feasible, and effective intervention for attentional rehabilitation, and to explore its future integration with neuromodulation techniques. The project was embedded in a broader political and strategic framework promoting digital health solutions, innovation in neurorehabilitation, and evidence-based, personalized medicine within the European Union.

By generating clinical, behavioral, and neurophysiological evidence, NeMoRe sought to address the need for more engaging and scalable rehabilitation tools, while strengthening European expertise in advanced neurotechnologies for health. The expected impact spans clinical practice, research innovation, and health system sustainability.

Travail effectué depuis le début du projet jusqu’à la fin de la période considérée dans le rapport et principaux résultats atteints jusqu’à présent

During the fellowship, the project focused on the full implementation of the first scientific objective: the validation of EEG-based neurofeedback as a cognitive rehabilitation intervention in ABI patients. Following extensive methodological refinement and specialized training, a controlled clinical study was conducted comparing a neurofeedback intervention to standard cognitive rehabilitation.

Key activities included protocol optimization, ethics approval procedures, patient recruitment, administration of a 12-session neurofeedback training program, and comprehensive pre- and post-intervention assessments. Behavioral outcomes targeted attention and working memory, complemented by patient-reported measures addressing feasibility, safety, and motivation. Neurophysiological data (EEG and P300) were also collected to support mechanistic interpretation.

The main achievements of the project include the successful implementation of a complex neurofeedback protocol in a clinical population, demonstration of excellent safety and tolerability, and high patient engagement and motivation. Behavioral analyses revealed selective improvements and trends favoring neurofeedback on attention and working memory measures, while confirming the strong influence of baseline cognitive status on rehabilitation outcomes. These results establish a solid empirical foundation for further investigation and clinical translation.

Progrès au-delà de l’état des connaissances et impact potentiel prévu (y compris l’impact socio-économique et les conséquences sociétales plus larges du projet jusqu’à présent)

NeMoRe advances the state of the art by providing controlled, clinically grounded evidence on the feasibility and patient acceptability of EEG-based neurofeedback in ABI, a population underrepresented in neurofeedback research. Unlike many previous studies, the project adopted a conservative and methodologically rigorous approach, prioritizing safety, interpretability, and real-world applicability over overly complex experimental designs and non-controlled/open label studies.

The results highlight neurofeedback as a promising complementary tool to conventional rehabilitation to improve attentional cognitive processes, particularly due to its high motivational value and patient-perceived benefits. Importantly, the project also clarifies methodological challenges, such as the limitations of placebo neurofeedback and the need to account for clinical heterogeneity, thus contributing valuable guidance for future trials.

Beyond immediate scientific outcomes, the project identifies key needs for further uptake, including integration of neurophysiological markers as predictors of response, and evaluation of combined interventions. Continued research is already secured through additional regional funding, ensuring progression toward clinical scalability and long-term impact.
