Analysis of information sources in references of the Wikipedia article "Haltlose personality disorder" in English language version.
Of all psychiatric syndromes, the hysterical personality provides the nearest analogy to the unstable psychopath. The two are often seen combined, and in the irresponsible psychopath there is an emotional immaturity very like that of the hysteric. Kraulis (1931) found a rather high proportion of unstable drifters among the relatives of hysterics; and this suggests a genetical relationship.
