Two cases of electroconvulsive therapy (ECT) in adolescence are presented and the literature on the use of ECT in childhood and adolescence is reviewed. ECT was effective in children and adolescents with bipolar disorder and depression. Inadequate information exists to make a judgment regarding schizophrenia, delirium, and anorexia nervosa. ECT is not effective in autism and chronic organic brain syndromes. Complications cited include organicity and seizures in the period immediately after ECT, anxiety reactions, and disinhibition. Long-term memory deficit or cognitive impairment has not been found, although further research to rule out residual impairment is needed.

A 4-year-old child was referred to us from neurology with a possible diagnosis of autism. This form of acquired aphasia is unusual in that our patient did not ever present any clinical seizure in spite of bilateral temporal injury. One of the etiological possibilities that has been retained in those cases has to do with the aphasia being related to the convulsive disorder. Our case suggests that, at least for some of those children suffering from this unusual form of acquired aphasia, one has to look for some other etiological possibilities. This last point will be discussed as well as the value of sleep EEG as a diagnostic procedure.

Various theories have been provided in the literature regarding the etiology of infantile autism. It seems that the biological causation dominates the thinking of mental health practitioners and researchers irrespective of discipline. Areas of research include the following: neuropathological studies of the brain, autopsies, electroencephalograms, epileptic seizures, brain lateralization, studies in asymmetry; neurochemistry; genetics; and pre-, peri- and postnatal factors. A critical analysis of these studies has indicated that the evidence of organic factors tends to be rather weak and furthermore has been found to be contradictory. It is felt that the major problem lies in the fact that a large number of investigators include in their sampling children with various mental and physical disabilities and label them autistic. In general, there seems to be little information regarding the selection and little background information is offered on these children. It is suggested that a standardized and world wide diagnostic system be constructed which will provide objective etiological results.

Rett syndrome (RS) is characterized by progressive loss of intellectual functioning and fine and gross motor skills as well as development of stereotypic hand movement abnormalities, occurring after 6 to 18 months of normal development. Rett syndrome has been previously reported only in girls, but the possibility of the syndrome existing in male children cannot be currently excluded. Although the syndrome is thought to be relatively common, it was only described in the English literature 5 years ago. There is currently no marker for the syndrome; diagnosis is based on clinical criteria. The newly developed diagnostic criteria for RS are reviewed, with special attention given to the historical aspects of the diagnosis in the prenatal, perinatal, neonatal, and early childhood periods. Rett syndrome is characterized by a predictable, orderly progression of signs and symptoms. Four stages of RS have been described; each stage has special characteristics and offers different diagnostic challenges for the neurologist. Infantile autism is the most common incorrect diagnosis made for children with RS. The simultaneous regression of both motor and language skills, as well as the stereotypic hand movements, hyperventilation, bruxism, and seizures in early childhood are all typical in RS and help distinguish RS from infantile autism.

The clinical spectrum of autism spans a broad range of functions, but the core symptoms remain the same regardless of the intelligence of the child: the autistic type of social deficit that ranges from a lack of inclination to relate to extreme difficulty with the mechanics of social interactions, a global communication deficit that involves both verbal and nonverbal modes, and a severe cognitive deficit involving concept formation (abstraction) that is combined with an exceptional memory for factual information. These symptoms may vary dramatically in severity, but the basic deficits are identifiable regardless of IQ. Under-recognition of autism is a major problem at all IQs, but especially in patients with IQs above 50. No drugs have been found to significantly improve the core deficits in autism. Antipsychotics should be avoided except for short-term use. Antidepressants, anxiolytics, and anticonvulsants are important in the treatment of depression, affective modulation, situation-related stress, and seizures. Intensive social skills training is assuming a prominent role in behavior modification programs, and success with higher-functioning autistic children suggests that outcome can be improved by intensive training. The neurobiology of autism has also undergone dramatic changes. The psychogenic theories of etiology have been completely invalidated. Autism is now considered to be a neurological disorder resulting from an error in brain development. The precise location and nature of this deficit are still being actively debated and investigated. One theory emphasizes a dysfunction of the limbic system that results in an impairment in the acquisition of information. A second theory proposes a primary role for dysfunction of the cortical association network responsible for the processing of information.

Clinical and EEG findings have been analysed in six patients with Rett syndrome with a mean follow-up of 3 years and 9 months. After reviewing the diagnostic criteria for inclusion, which are essentially clinical, we emphasize two aspects which have been shortly considered in the literature: a) epileptic seizures, b) peculiar differential characteristics between primary autism and the Rett syndrome behaviour. Moreover, we underline the importance of serial EEG poligraphic records for early diagnosis.

Rett syndrome is a progressive encephalopathy observed only in girls, who are apparently normal until 6 to 12 months of age. It is characterized by autism, dementia, ataxia, stereotypic hand movements, hyperreflexia, spasticity, and seizures. Eight of 10 females with Rett syndrome evaluated at the Alfred I. duPont Institute have C-shaped neuromuscular curves averaging 29 degrees (range 22-48 degrees). Curve progression was seen in all eight patients and occurred despite bracing in four, averaging 21 degrees (range 12-31 degrees). Five patients, two of whom were braced, have undergone posterior spinal fusion with segmental instrumentation for curves ranging in size from 49 to 105 degrees (average 67 degrees).

This study examines the incidence rate of setback in 80 autistic children, the correlation between the type of onset and clinical features, developmental level and prognosis based on an originally developed questionnaire. Moreover, this study seeks to investigate the possibility that infantile autism might be classified into subgroups by the type of onset. 1) The acquired (including questionably acquired) group consisted of 39 cases (49%), while the natal group was made up of 41 cases (51%). 2) The age when the setback occurred was 21-22 months in the acquired group. 3) Precipitating psychological events were observed in 22 cases (56%) of the acquired group. 4) The mental developmental level including speech and socialbility function at 5 years of age was significantly lower in the acquired group than in the natal group. 5) The acquired group showed severe behavioral disorders such as "stereotypic behavior," "extremely hyperkinetic behavior" and "self-abusive behavior" compared with the natal group. 6) The adaptive levels at schools or institutions were lower in the acquired group than in the natal group. 7) There was a higher incidence of epileptic seizures or febrile convulsions in the acquired group than in the natal group. Moreover, there was a higher incidence of severe perinatal abnormalities in the acquired group. 8) The above-mentioned results suggest that infantile autism might be classified into two subgroups, acquired and natal groups, based on the type of onset, and also suggest that some types of brain dysfunctions are more severe in the acquired group than in the natal group.

Syncopes due to compulsive respiratory stereotypies were studied in eight patients with autistic features. Most had been referred for episodes thought to be intractable epileptic seizures. Polygraphic recording showed two types of syncope, one induced by prolonged apnea and the other by a prolonged Valsalva maneuver. Fenfluramine, 1.5-3 mg/kg per day, was given in an open trial. In four of five cases with frequent Valsalva maneuvers, respiratory stereotypies and syncopes were suppressed for 2-18 months. Patients with periodic apneas were more severely retarded and had less clear benefit. Side effects consisted of dose-dependent sedation and mild weight loss which stabilized without interrupting treatment. We suggest that these syncopes are volitional and may be associated with pleasant sensations. A double-blind placebo-controlled trial of fenfluramine seems warranted in such patients.

Early infantile autism is a behaviorally defined syndrome that is often associated with abnormalities on neurologic examination and seizures. We report on the brain of a 29-year-old autistic man as compared with that of an age- and sex-matched normal control, using gapless sections of whole brain. Abnormalities were found in the hippocampus, subiculum, entorhinal cortex, septal nuclei, mamillary body, selected nuclei of the amygdala, neocerebellar cortex, roof nuclei of the cerebellum, and inferior olivary nucleus.
