Psychological Tension‒Induced Calcium Channel Sensitization and the Generalized Hypersensitivity Syndrome: A Developmental Neurobiological Hypothesis

This paper proposes a unified neurobiological hypothesis called the Generalized Hypersensitivity Syndrome (GHS), explaining how psychological tension induces systemic overreactivity across neural, muscular, autonomic, and immune systems.The author suggests that chronic psychological stress increases calcium channel sensitivity and density (Ca²⁺ upregulation) through continuous release of intercellular signaling molecules such as ATP, substance P, and cytokines.This mechanism amplifies excitability, muscle tension, immune hypersensitivity, and autonomic imbalance. Furthermore, early-life fear experiences (around age 5–6) may imprint maladaptive plasticity in the amygdala–hypothalamus–prefrontal network, resulting in lifelong vulnerability to tension-induced symptoms such as speech dysfluency, swallowing difficulty, tremor, panic attacks, and hyperventilation.The hypothesis integrates psychiatry, physiology, and neurodevelopment, offering new insight into the biological basis of psychogenic disorders and potential therapeutic approaches involving calcium modulation and emotional retraining.
