The effectiveness and information content of thermography were studied in 20 normal subjects and 40 patients with vegetative vascular dystonia. There were some individuals in the control group who had "thermal amputation" and who also had some specific features of psychovegetative nature. Patients with vegetative vascular dystonia, apart from the syndrome of "thermoamputation" observed in a great number of cases, particularly in neurotic patients, had other types of skin temperature distribution as well. Thus, patients with hypothalamic insufficiency presented with hyperthermia of the distal portions of the extremities and asymmetry.
