The response of plasma 11-hydroxycorticosteroids (11-OHCS) to intravenous pyrogen as well as the circadian rhythm of plasma 11-OHCS levels were investigated in seven autistic children and in two children with Heller's syndrome. In autistic children, the stress response, which is acquired in an earlier stage of development, was adequately sustained. However, the circadian rhythm, which seems to appear at a later stage with the maturity of the CNS, frequently revealed abnormal patterns. Similar findings were obtained in the Heller's syndrome cases, indicating organic changes in the brain. On the basis of these results, it is postulated that in early infantile autism there exist some functional changes in the CNS that show a close correlation to the regulatory mechanism of ACTH secretion.

To investigate clinical pictures and the validity of disintegrative psychosis (DP) as defined in ICD-9, 18 cases of DP were compared with 51 and 145 cases of infantile autism (IA) with and without speech loss, respectively, on clinical variables. The DP cases showed clearer regression after more satisfactory development than the IA cases with speech loss. Around age 7, about 4 years after regression, those with DP were significantly more severely retarded than those with IA, yet both were similar in autistic symptomatology. EEG abnormalities and mothers 30 or older at delivery were significantly more common in the histories of those with DP than of those with IA. DP may be linked with IA having speech loss with regression in mental development as a common denominator.

Childhood disintegrative disorder, also known as Heller syndrome or as disintegrative psychosis, is a relatively uncommon condition which has variably been included in official diagnostic systems. Available evidence regarding the validity of this diagnostic concept, particularly with regard to autism, supports inclusion of the category in DSM-IV. Proposed criteria and narrative description for the disorder are presented.

At present, although autism has become accepted as a pervasive developmental disorder, renewed attention is being turned upon the relationship between autism and childhood schizophrenia in recent years. Likewise, the relationship among Heller's syndrome, autism, and childhood schizophrenia has also become a focus of clinical interest. The author presents a case in which discrimination among autism, Heller's syndrome, and childhood schizophrenia is difficult, supplementing discussion from the nosological standpoint. The subject is a male, who was 7 years old at first presentation. Early signs of disorder other than a delay in verbal development were not recognized. At around age 3, a tendency to become isolated at nursery school, and a rambling speech without cohesion was noted at home. Also around this time, the subject was seen to take an obsessive interest in written characters and maps. However, a drastic increase in the severity of symptoms occurred at about 1 week after entering 1st grade with the sudden appearance of hyperactive tendency, accompanied by anxiety at night and loss of control over both urinary and bowel functions. This was followed by the appearance of severe self-injurious behavior, for which the subject came under the care of the author. Subsequently, the author has been involved with the subject therapeutically for about 10 years. In that interval, although a tendency of improvement has been noted in his condition, no substantial change has been recognized in terms of the fundamental disease picture.

Speech loss (SL) was compared in 276 children who had pervasive developmental disorders (PDD) with 62 children with intellectual disabilities without PDD. Speech loss seems relatively specific to PDD because it is significantly more common in children with PDD (26.1%, 72/276) than in those with intellectual disabilities (1.6%, 1/62). In three PDD categories, speech loss occurred in all the 12 children with disintegrative psychosis, 35/149 (23.5%) children with infantile autism and 25/115 (21.7%) children with other PDD. Children with pervasive developmental disorders and speech loss had spoken significantly earlier yet developed less satisfactorily after speech loss than those without it. Speech loss seems fairly specific to PDD and is indicative of unfavorable intellectual development in children with PDD.

This study aimed to investigate the validity of disintegrative psychosis (DP) as defined in the ICD-9. The history of epilepsy in 13 subjects with DP was compared with that of 39 subjects with infantile autism (IA) who were matched for sex, age, IQ, and socioeconomic status (SES). The average follow-up time was 22 and 23 years (range 11 to 33 years). A significant difference was found between the DP and IA groups in terms of incidence of epilepsy, 77% versus 33% respectively. The peak period of onset of epilepsy occurred before puberty in both groups. Different types of epilepsy were seen, but the psychomotor variant accounted for 50% in the DP group, while 46% of the IA group had the psychomotor and 62% had the grand mal variant. The types are not mutually exclusive. Individuals without epilepsy had significantly higher IQ scores than those with epilepsy, but only within the IA group. The increased risk of developing epilepsy in the DP group is most likely a reflection of an underlying early brain pathology probably present in most individuals with DP. On the whole our findings can be seen as a contribution to the validation of DP as separate from IA, as these two conditions could be distinguished in terms of the way they develop with reference to epilepsy.

In order to study the validity of disintegrative psychosis (DP), the authors compared 13 patients given this diagnosis in childhood with a control group of 39 patients with infantile autism (IA) matched for sex, age, IQ and social class on measures of psychiatric morbidity. Almost the same proportion of the two groups had been admitted to a psychiatric hospital during a 22-year follow-up period. However, there was a slight tendency (statistically nonsignificant) for the DP group to utilize the psychiatric health care system more frequently than the IA group. They had more admissions and stayed longer in hospital than patients with IA suggesting that they had more psychiatric symptoms than the IA group. The original IA diagnoses were confirmed fairly consistently during the follow-up period, while the DP group was given more heterogenous diagnoses. No diagnosis of schizophrenia was made in either group.

In order to study the validity of disintegrative psychosis (DP) as defined in ICD-9, we compared the natural history of somatic morbidity of 13 patients given this diagnosis in childhood with a control group of 39 patients with infantile autism (IA) matched for gender, age, IQ and social class. Average follow-up time was 22 and 23 (11-33) years, respectively. Significantly more DP patients (85 versus 41%) had been admitted to a non-psychiatric hospital during the follow-up period. They also had significantly more admissions (3.6 versus 1.0) and stayed longer in hospital (78 versus 4 days) than patients with IA. Three of the DP individuals had an associated medical disorder and made extensive use of somatic services during the follow-up period. Altogether the DP group had utilised the medical health care system more than patients with IA suggesting that they had more medical symptoms than the IA group. On the whole our findings suggest that individuals with DP and IA should be conceptualised as essentially distinct and should be studied separately as regards aetiology, pathophysiology, course and treatment.

Childhood disintegrative disorder (CDD) is a clinical syndrome characterized by disintegration of mental functions and regression of acquired language and intellectual functions after a period of normal development typically of 3 to 4 years. Although recognized for many years, research on this condition is less advanced than that in autism. Epidemiological data are limited but the condition is much less common than autism. The relationship of this condition to autism remains the topic of debate. Neuropathological and other medical conditions are sometimes associated with the disorder but contrary to earlier belief this is not typical. Collaborative research would facilitate our understanding of this condition.

First termed Dementia Infantilis by Theodore Heller in 1908, Childhood Disintegrative Disorder (CDD) has had a history longer than that of Autistic Disorder. Presently, CDD is classified as a Pervasive Developmental Disorder in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders. The characteristics most often cited as distinguishing CDD from Autistic Disorder, another one of the Pervasive Developmental Disorders, is the age of onset and evidence of normal development prior to the presence of symptomatology. Otherwise, the behavioral symptoms of CDD and Autistic Disorder are strikingly similar. The purpose of this article is to provide a historical background on CDD, examine the evolution of diagnostic criteria, review the existing literature pertaining to the disorder, and, finally, to draw conclusions regarding the validity of CDD as a distinct diagnosis with reference to current and alternative classification approaches.
