Many symptoms of infantile psychoorganic syndrome can be regarded as developmental variants or as the result of retarded development, particularly where they are not of marked degree. However, many symptoms are not assignable to either of these categories but, with respect to their pathology, must be classified otherwise. Thus it follows that infantile psychoorganic syndrome as a total entity--and only as a totality, of course, is it to any extent specific--cannot be viewed as a disorder of development.
