title: A psychophysiological hypothesis on the aetiology of duodenal ulceration.
abstract: A previously undescribed explanation for the development of duodenal ulcer is advanced. Stressful situations and avoidance-avoidance conflicts in individuals with a dependant compliant personality incapable of appropriate "stimulus-seeking behaviour" lead to an immobilised state. This predicament is denied. Helplessness develops. This state is associated with an autonomic imbalance in which a central monoamine depletion results in uncompensated parasympathetic overactivity which facilitates the development of duodenal ulceration. Denial often invalidates superficial psychological investigations into the aetiology of duodenal ulceration and may explain the contradictory findings in the literature.
