Clinical Report: Tarlov/Meningeal Cysts, Spinal Stenosis, Chiari 1 Malformation, and Chronic Pain Experience — Clinical Correlation with MRI Findings

When Pain Becomes Unbearable and Symptoms Spread Understanding the MRI Findings, Nerve Irritation, Sacral Pain, and the Reality of Chronic Spinal Disease This reflects the lived experience of chronic spinal pain and nerve irritation associated with lumbar degeneration, postoperative changes, foraminal stenosis, facet arthropathy, and sacral nerve sensitivity. Chronic spinal pain is rarely caused by a single abnormality. In patients with prior lumbar surgery and degenerative spinal disease, pain often develops from several interacting conditions, including foraminal narrowing, facet arthropathy, nerve inflammation, postoperative changes, and sacral cyst-related nerve sensitivity. Over time, symptoms may gradually progress until routine activities — sitting, standing, walking, bending, or even resting — provoke significant discomfort. The MRI findings described here suggest a spine affected by chronic degeneration, mechanical compression, postoperative inflammatory change, and nerve ir...

How SARS-CoV-2, Hantaviruses, Zika virus, and Other Pathogens Hijack Extracellular Vesicles to Invade the Brain and Drive Neuroinflammation

By
Over recent years, research has revealed a more indirect and sophisticated way that viruses influence the nervous system. Rather than relying solely on direct infection, multiple viruses exploit extracellular vesicles (EVs)—small, membrane-bound particles naturally used for cell-to-cell communication—to spread viral material, evade immune defenses, and trigger inflammation. This EV-mediated mechanism provides a compelling explanation for neurological symptoms seen during acute infections and in post-viral syndromes such as long COVID. Extracellular Vesicles: A Double-Edged Sword Extracellular vesicles are essential for normal biological communication. Cells use them to transport proteins, lipids, and RNA between one another. However, many pathogens—including SARS-CoV-2 and Zika virus—co-opt this system. Evidence shows that infected cells release EVs containing viral RNA, proteins, and sometimes intact viral particles. These vesicles function as stealth carriers: They shield viral...
