Primary trigeminal neuralgia (algophoric deafferentation hypersensitivity syndrome).

In the article the author presents his theory of the pathogenesis of primary trigeminal neuralgia, explaining the occurrence of this mysterious disease by algophoric deafferentation hypersensitivity. Tooth extraction is the sole cause of algophoric deafferentation hypersensitivity, which, culminating in epileptiform discharges of the trigeminal nociceptive pathway neurons, leads to clinical features of characteristic neuralgic paroxysms. Trigger mechanism is explained by ephaptic transmission between the broken fibers for phasic pain of the tooth pulp and neighbouring fibers of epicritic and proprioceptive sensitivity. The typical occurrence of periods with remission of neuralgic paroxysms the author explains by his original theory of biorhythms neogenesis with the involvement of two antagonistic neural subsystems (nociceptive and antinociceptive system). The concept is based on indisputable clinical, anatomical, pathoanatomical, experimental and pharmacologic facts, which the author quotes as the contribution to his theory.
