Integrated Neurorehabilitation Including EEG-Neurofeedback for Unilateral Spatial Neglect After Right Thalamo-Mesencephalic Intracerebral Hemorrhage: A Case Report

Background/Objectives: Unilateral Spatial Neglect (USN) is a disabling attentional syndrome occurring after cortical or subcortical stroke, including thalamic lesions. EEG-based neurofeedback (EEG-NF) may support cortical self-regulation, but evidence in spatial neglect remains limited. This case report describes the clinical, neuropsychological, functional, and electrophysiological (quantitative EEG, qEEG) evolution of a patient with USN after a right thalamic hemorrhagic stroke who underwent multidisciplinary rehabilitation including EEG-NF. Methods: A 70-year-old patient underwent a 3-week inpatient multidisciplinary rehabilitation program including physiotherapy, speech and swallowing therapy, conventional cognitive stimulation, and 15 adjunctive EEG-NF sessions. Baseline and post-treatment assessments included clinical, neuropsychological, neglect-specific, functional, affective, and resting-state qEEG measures. Individual change was examined using the Reliable Change Index when suitable psychometric parameters were available, together with published normative and clinical thresholds. Results: After rehabilitation, the Montreal Cognitive Assessment total raw score increased from 20 to 24, reaching the published minimal clinically important difference but not the minimal detectable change. The Frontal Assessment Battery increased from 8 to 12; after adjustment for age and education according to Italian normative data, both scores remained below the normative cut-off. Neglect-specific measures showed reduced spatial asymmetry, increased contralesional target detection, and a Catherine Bergego Scale reduction from 17 to 5, indicating a shift from moderate to mild ecological neglect. Functional independence improved, with reliable change in Functional Independence Measure (FIM) total and cognitive scores and Modified Barthel Index scores. Exploratory qEEG analyses showed condition-dependent spectral and connectivity changes, but findings were heterogeneous and hypothesis-generating. EEG-NF was completed without adverse events. Conclusions: The adjunctive EEG-NF protocol was completed as planned, with no adverse events. Clinical improvement cannot be attributed specifically to neurofeedback because all rehabilitation components were delivered concurrently. Controlled studies are needed to clarify its specific contribution and the durability of the observed improvements in post-stroke spatial neglect.
