The authors are concerned with the contribution of anxiety in origin of functional behavioural disorders of children. They attribute the intense sensing of anxiety with the shaping of one's personality. They analyse adaptation and adjustment, accommodation and assimilation to stressful conditions producing anxiety. They describe reactions of organism to the circumstances of the CAN syndrome and traumas. In these circumstances, a primary perception of reality is at stake that consequently leads to sociopathological features. The authors also provide opinions of psychoanalytical and behavioural schools on origin of personal decompensation and neurotic disorders. They deal with causes of panic disorder and other diseases, in which a stress trauma plays a role.

For these reasons the authors suggest to classify the CAN syndrome as a separate nosologic unit in the future ICD-11.
