Regression neurosis is a psychological condition characterized by a person's retreat into behaviors and thought patterns that are typical of an earlier stage of development. The condition can be identified by symptoms such as increased dependence, stubbornness, and regression to childish behavior. This condition can be treated through psychoanalytical therapies, which aim to identify the underlying causes of the regression and resolve them through conscious reprocessing. Other synonyms for the condition include primitive defense mechanisms, neurotic regression, and fixation. It is important to seek professional help in dealing with regression neurosis since it can lead to significant social and professional difficulties if left untreated.
