Introducing a New Traumatic Brain Injury Assessment and Recovery that Promises Fuller Healing
A groundbreaking new system for evaluating traumatic brain injuries (TBI) was recently published in the journal Lancet Neurology, as detailed in a New York Times article. This new classification system, developed by 94 experts from 14 countries, aims to improve how patients with traumatic brain injuries (TBI) are evaluated and treated. For decades, TBI assessments often relied on the Glasgow Coma Scale, which categorizes injuries as mild, moderate, or severe based on basic responses. However, as neurosurgeon Dr. Geoffrey Manley highlights, this oversimplified approach can lead to misdiagnoses and insufficient care, with some "mild" injuries resulting in persistent problems and some "severe" cases achieving full recovery.
The new system incorporates additional factors such as post-traumatic amnesia, headaches, sensitivity to light or noise, blood biomarkers of brain injury, and scans like CT and MRI to look for issues such as blood clots, skull fractures, and hemorrhaging. It also uniquely considers the patient's social environment, recognizing its impact on recovery. This more comprehensive approach seeks to end reliance on oversimplified testing and help researchers develop better drug treatments and procedures.
While these advancements are crucial, they still primarily focus on structural damage and general symptoms. This is where Z-score LORETA (Low Resolution Electromagnetic Tomography) Analysis and Neurofeedback, also referred to as advanced neurofeedback, offer a revolutionary leap forward.
Beyond the Surface: Pinpointing Brain Network Dysfunction
Traditional EEG can map the surface of the cortex, providing some benefit, but it's limited in its ability to delve into the brain's deeper structures, which are central to many mental health functions and dysfunctions. Z-score LORETA (ZL-Neurofeedback), on the other hand, allows for a 3D distributed, linear imaging of electric neuronal activity, providing a much more precise view of what's happening beneath the surface.
Imagine the brain's intricate networks like an orchestra. Just as beautiful music requires precise timing and coordination between all sections, mental health, and optimal brain function depend on regions of the brain communicating and coordinating effectively. When this connectivity breaks down, it's like a discordant symphony, leading to mental health challenges. Z-score LORETA (ZL-Neurofeedback) excels at identifying these breakdowns in "functional connectivity" – how different brain regions communicate and work together.
Precision Neurofeedback: Retraining the Brain for Recovery
Neurofeedback is a form of biofeedback that trains brain activity using EEG. Electrodes measure the brain's electrical activity, and a computer converts the EEG signal into real-time visual feedback, allowing the patient to engage in video content where rewards are given when brain waves move in a desirable direction. Over time, the brain learns to move its waves successively closer to the goal. With Z-score LORETA (ZL-Neurofeedback), this training can focus on normalizing all aspects of communication between areas.
Unlike traditional neurofeedback, which often relies on single metrics and fixed protocols, Z-score Neurofeedback utilizes multiple simultaneous measures, is database-driven, provides a whole-brain perspective, and allows for dynamic adjustment of protocols. This "precision neurofeedback" approach has shown promising results in clinical studies, often requiring fewer sessions than traditional methods. In fact, in 2024, the FDA cleared a LORETA-based neurofeedback device ("PRISM") for PTSD and ADHD, specifically training functional connectivity between the PFC and amygdala (areas of the brain).
Case in Point: A Professional’s Remarkable Recovery from Concussion
Consider the case experience of GG, a 41-year-old tech executive who presented for care two months following her third lifetime concussion, sustained in a bicycling accident. She reported significant cognitive deficits—specifically in memory, organization, and attention—which severely impacted both her professional efficacy and personal well-being. Despite her neurologist’s assurance of a full physical recovery and clearance to resume all activities, GG remained deeply concerned by her persistent decline in productivity at work.
Our diagnostic process began by precisely mapping the high-resolution 3D information flow within her brain using advanced electrical activity measurements. Through Z-score LORETA (ZL-Neurofeedback) analysis, we rigorously compared GG's unique brain map against a normative database of over 200 age-matched individuals. This allowed us to pinpoint with accuracy the specific neural pathways where the concussion continued to exert its detrimental effects.
Over the subsequent four weeks, GG underwent eight targeted neurofeedback sessions. These interventions were designed to facilitate the brain's innate capacity to rewire injured connections and restore optimal information processing. The results were compelling. Post-treatment, GG enthusiastically reported, 'That was amazing! I can’t believe what a difference it made in my focus and thinking.' She also noted a marked reduction in headaches and the near elimination of residual 'brain fog.' Crucially, GG regained her full sense of competence and engagement in both her professional and family life. She continued with an additional eight sessions, achieving further profound advancements that solidified her recovery.

This case highlights how Z-score LORETA analysis can provide a deeper understanding of brain dysfunction following injury and how Z-score LORETA (ZL-Neurofeedback) can support a fuller, more targeted recovery by training the brain to re-establish healthy communication pathways. While the new TBI classification system is a vital step forward, integrating precision neurofeedback with Z-score LORETA (ZL-Neurofeedback) offers a powerful complement, enabling more comprehensive assessment and personalized interventions for those recovering from brain injuries.
