New Data Confirms DIFS Improves Cognitive Function and Restores Brain Activity in Alzheimer's Patients


HOUSTON, TX, Oct. 28, 2024 (GLOBE NEWSWIRE) -- Nexalin Technology, Inc. (Nasdaq: NXL; NXLIW) (the “Company” or “Nexalin”) today announced publication of a landmark study titled, “Altered Neuronal Activity Patterns of the Prefrontal Cortex in Alzheimer’s Disease After Transcranial Alternating Current Stimulation (tACS): A Resting-State Functional Magnetic Resonance Imaging Studyi” in the Journal of Alzheimer's Disease. This study builds on recent findings from Nexalin's Deep Intracranial Frequency Stimulation (DIFS) research and further highlights the effectiveness of non-invasive neurostimulation in enhancing brain function and improving cognitive performance in patients with mild Alzheimer’s disease (AD).

This new research involved 46 patients, randomly assigned to receive either real DIFS or sham treatment for 30 one-hour sessions over a period of three weeks. Resting-state functional magnetic resonance imaging (rs-fMRI) was used to track changes in brain activity, showing that Nexalin’s proprietary DIFS technology significantly alters neuronal activity in key regions of the brain, providing a non-pharmacological, safe treatment option for Alzheimer’s.

Key Findings of the Study Include:

  • Increased Neuronal Activity and Glucose Metabolism: Patients receiving real DIFS exhibited significant increases in fractional amplitude of low-frequency fluctuation (fALFF) in key brain areas like the prefrontal cortex. fALFF, which measures regional spontaneous neuronal activity, has been shown to correlate with glucose metabolism, a crucial process for cognitive function that is often impaired in Alzheimer’s patients. This suggests that DIFS may help restore metabolic functions within the brain, contributing to improved cognition.

  • Sustained Cognitive Benefits: After three weeks of treatment, patients showed improvements in cognitive function, which were sustained over a three-month follow-up.  Increased neuronal activity was observed in regions such as the superior parietal lobule and inferior temporal gyrus, both of which are critical for memory and cognitive processing. These results indicate that DIFS has long-lasting effects, potentially offering extended cognitive support for Alzheimer’s patients.

  • Enhanced Brain Connectivity: The study found improvements in regional homogeneity (ReHo) in the left middle frontal gyrus and right superior medial frontal gyrus, indicating better synchronization of neural activity between different brain regions. The modulation of brain networks by DIFS underscores its potential to improve cognitive function by enhancing brain communication pathways.

  • Correlations with Improved Blood Flow and Brain Function: Enhanced blood flow was observed in several critical regions, correlating with the increases in neuronal activity. This improvement in both glucose metabolism and blood flow suggests that DIFS can help restore disrupted metabolic processes in the brain, which are commonly affected in Alzheimer's patients. Increased blood flow, particularly in memory-related areas, aligns with previous findings on Nexalin’s DIFS technology, further solidifying DIFS’s potential as a complementary non-invasive treatment for Alzheimer’s.

  • Safe and Well-Tolerated Treatment: Importantly, the study indicated no serious side effects reported among participants. Despite undergoing twice-daily stimulation sessions over three weeks, elderly patients tolerated the treatment well, with only minor sensations such as tingling that resolved quickly. This profile is particularly critical in vulnerable populations such as Alzheimer’s patients.
