Abstract

BACKGROUND: The electromagnetic field (EMF) of the brain can be modulated through EMF stimulation. The authors investigate whether longer duration of continuous EMF stimulation using a novel method to identify and provide feedback and adjustment of EMF recording would translate into sustained improvement in EMF patterns, such as higher amplitude with correlating improvement in clinical symptoms or deficits. METHODS: From January 2025 to February 2025, a prospective study enrolled patients greater than 18 years old diagnosed with atraumatic and traumatic brain injury who underwent EMF stimulation within 24 hours of presentation. EMF data were collected using DAQami software (Dataq Instruments, Akron, Ohio) and analyzed using fast Fourier transformation (FFT) with Igor Pro 8 software (Wavemetrics Inc., Lake Oswego, Oregon). Based on each patient's clinical presentations and/or radiographic findings, localization of brain injuries, frequency selection, and optimal voltage stimulation were determined in real-time followed by delivery of incremental increase in duration of stimulation from 3, 5, 8, and 10 minutes until improvement in clinical symptoms and/or neurological deficits and sustained EMF change was achieved. RESULTS: Ten patients were included in this study, with a mean age of 47.1 years. Mechanisms of injury included spontaneous hypertensive intracranial hemorrhage (1 patient) and head trauma after motor vehicle collision, dirt bike accident, and ground-level fall (9 patients). Radiographic findings included spontaneous basal ganglia hemorrhage (1 patient), isolated traumatic subdural hematoma (1 patient), traumatic subarachnoid hemorrhage (1 patient), and no intracranial abnormalities (7 patients). Clinical resolution of their neurological symptoms or remaining asymptomatic was achieved in five patients after three minutes of continuous EMF stimulation, two patients after five minutes of continuous EMF stimulation, and one patient after 10 minutes of continuous EMF stimulation (Table 1). Patient 8 declined to continue with the study after three minutes of continuous EMF stimulation, and patient 9 declined to continue with the study after five minutes of continuous EMF stimulation. CONCLUSIONS: This study reveals the progress made to date utilizing a novel technology of EMF measurement at a distance, in real-time, using the non-invasive, lightweight portable helmet, and continuous feedback. The range of brain EMF can be stimulated at the optimal frequency and voltage with or without longer duration of stimulation in a precise and prescribed manner to produce sustained genetic and neuronal changes to improve, recover, and enhance the brain function in a sample of patients with atraumatic and traumatic brain injury and improve or resolve their neurological symptoms or deficits. It illustrates the necessity of real-time evaluation and adjustment of brain EMF for EMF stimulation. It further indicates the efficacy of tailored and precise EMF stimulation to the specific patient, the specific area of abnormality, and for a specific pathology studied. The range of unique EMF corresponds to macroscopic and microscopic functions, the vast majority of which have yet to be qualified and quantified, and for which most brain diseases have yet to be studied.

Main findings

In 10 adult brain-injury patients receiving tailored cranial EMF stimulation, clinical resolution of neurological symptoms or remaining asymptomatic was reported in 5 patients after 3 minutes, 2 patients after 5 minutes, and 1 patient after 10 minutes of continuous stimulation; 2 patients declined to continue after 3 or 5 minutes.
