Dissociation Under Extreme Pain and Threat: A Neuroscientific View of "Becoming a Robot"

By
The experience of becoming "like a robot" during overwhelming pain, severe illness, childbirth, physical trauma, or abuse is often misunderstood. Many people assume that emotional numbness during a crisis reflects unusual toughness, stoicism, or an exceptional ability to tolerate pain. Modern neuroscience suggests a different explanation. In some individuals, overwhelming threat can trigger a dissociative survival response . During this state, pain may remain fully conscious, yet the person's normal sense of self, emotional awareness, body ownership, and perception of time become altered. The person continues functioning, sometimes remarkably effectively, but does so in a detached, automatic, almost mechanical manner. This response does not necessarily indicate a disorder. In many cases it represents an adaptive biological strategy that allows survival during circumstances that exceed the brain's capacity for normal emotional processing. The Characteristic Pattern...

Anti-MAG Peripheral Neuropathy: Understanding a Rare Autoimmune Nerve Disorder

By
Anti-Myelin-Associated Glycoprotein (Anti-MAG) peripheral neuropathy is a rare autoimmune neurological disorder in which abnormal Immunoglobulin M (IgM) antibodies mistakenly attack components of the peripheral nervous system. These antibodies target Myelin-Associated Glycoprotein (MAG), a protein essential for maintaining healthy nerve insulation, resulting in progressive nerve damage that can cause numbness, tingling, tremors, balance difficulties, and impaired mobility. The disorder is most commonly associated with monoclonal gammopathies, particularly Monoclonal Gammopathy of Undetermined Significance (MGUS), although it can also occur in association with Waldenström's macroglobulinemia and other low-grade B-cell disorders. Although Anti-MAG neuropathy is considered rare, it is one of the most recognized antibody-mediated peripheral neuropathies and requires specialized diagnostic testing and treatment approaches distinct from other autoimmune nerve disorders. What Causes Anti-...

ME/CFS: The Sodium–Calcium Cascade: A Possible Common Mechanism in Heart Failure and ME/CFS?

By
Ever since I watched Klaus Wirth's 2025 presentation (link), I have been intrigued by a cellular cascade that appears to play a central role in heart failure and may also be relevant to systemic illnesses such as ME/CFS. While the details are complex, the underlying mechanism illustrates how disturbances in cellular energy metabolism can trigger a self-perpetuating cycle of sodium overload, calcium dysregulation, mitochondrial dysfunction, and ultimately cellular damage. At its core, this cascade revolves around the delicate balance of sodium and calcium within cells and the energy-dependent systems responsible for maintaining that balance. Step 1: β₂-Adrenoceptor Stimulation Increases Metabolic Demand The process begins with activation of β₂-adrenoceptors, which stimulate cellular energy metabolism and increase metabolic activity. Under normal circumstances, this response helps cells meet changing physiological demands. However, sustained stimulation places additional pressure on ...
