{Abstract}: <B>BACKGROUND: </B>Electroencephalogram Neurofeedback therapy (EEG-NFT) has several potential beneficial effects in terms of improving cognition and electrophysiological regulation among patients with brain injury. However, in vivo structural and functional changes remain less explored.<BR><B>OBJECTIVE: </B>The aim of the present study is to explore EEG-NFT induced in vivo changes in traumatic brain injury (TBI) patients.<BR><B>METHODS: </B>Two patients with mean age of 15 years with moderate head injury who had more than seven post concussion symptoms and poor cognitive performances (<5 percentile) were subjected to 20 sessions of EEG-NFT. The neuropsychological test scores, post concussion symptoms and MRI scan of the brain were recorded pre-post to EEG-NFT.<BR><B>RESULTS: </B>During EEG-NFT the cognitive scores and concussion symptoms improved significantly (p < 0.05). The EEG-NFT has shown significant increase in cortical grey matter (GM) volumes (p < 0.0001) and fractional anisotropy (FA) of cortical white matter (WM) tracts (p < 0.0001, voxel max 60 and above). There was a significant decrease in global, local efficiency, cost and clustering coefficient of functional connectivity (Wilcoxon Sign Rank Test p < 0.05). Interestingly there was a significant increase in thalamo-cortical connection (increase FA value) after EEG-NFT.<BR><B>CONCLUSIONS: </B>The EEG-NFT therapy has shown significant changes in structural and functional connectivity among young moderately injured TBI patients.
