A uniform defective development of the physical and mental personality of the individual has been designated by Lasègue as infantilismus. As described by Di Gaspero and de Sanctis the mental status of these cases belongs to the domain of feeblemindedness and in some instances to imbecility. According to Kraepelin[119] the attention is easily attracted and as easily distracted. These individuals are inquisitive and flighty. Apprehension is defective. What they hear and see can only be related in a fragmentary and unreliable manner. They often learn readily and forget as quickly. Pende described the mental development as only one-third of the normal. Memory gaps are supplied by exaggeration and fabrication, as influenced by emotion or suggestion. Di Gaspero found falsification of memory in twenty per cent of his cases. Imagination is very active with a tendency to dreamlike unrealities, wonderful tales of adventure, etc. Mental processes are inadequate, vague and uncertain. The real and the unreal are not clearly differentiated. Explanations and descriptions are inaccurate and indefinite. Standards of value, size or time are vague. The store of ideas is impoverished and associations are poor. Calculations are slow and faulty. These persons are illogical, impractical and credulous. They are swayed by prejudices, catchwords and hasty judgment. Their range of thought is narrow and their viewpoint of life childish. The emotional and volitional content is immature. They are cheerful but lack earnestness, and are often ambitious and boastful. At other times they are likely to be despondent, timid, anxious, fearful and lacking in self-confidence. The mood is exceedingly variable. They are not industrious, cannot apply themselves constantly to any line of work, and tire easily. Their conduct is very uncertain and unreliable. Some have criminal tendencies. Occasionally hysterical symptoms appear. Evidences of an absence of physical development manifest themselves in all varieties of immaturity. These defects, according to Falta, are shown especially in the genitalia and the lymphatic apparatus, with a delay in the closure of the epiphysis and the retention of a childish physique generally. The skeletal framework shows a failure of development, the lower length of the body exceeds the upper slightly, if at all, the head is relatively large, the bones slender and the pelvis infantile in type. The sexual organs and the "vita sexualis" are those of a child. The blood shows a large lymphocyte count and a definite status lymphaticus is sometimes found to be present. The hairy development of the pubis and axillary surface is slight. The internal organs are normal. True infantilism, according to Falta, is not due to a glandular disturbance. He also maintains that the mind, while that of a child, is normal otherwise and shows no defects. Juvenile myxedema, hypophysial dystrophy and eunuchoidism, Falta would not include with the infantilismus group.
