Istanbul University, Istanbul, Turkey. Although the core features of autism do not change qualitatively, a gradual overall symptomatic improvement including an increase in adaptive skills is observed in most cases with age. Follow-up studies show that the diagnostic features, the differential diagnosis, and clinical problems of adult autistics differ substantially from that of autistic children. The differential diagnosis of older autistics include personality disorders, learning disabilities, and mood disorder. Depression, epilepsy, and behavioral problems such as aggression and agitation may be major clinical problems during adolescence. The early indicators of a better outcome include a higher level of IQ and language. Among the neuropsychological variables, measures of flexibility and cognitive shift are important as prognostic factors. Early behavioral and educational intervention may especially increase the adaptive skills of the patients and promote the in-family communication. The outcome studies of autism are particularly helpful in addre ssing the appropriate and most effective programs of remediation for adult autistics. Copyright 2000 by W.B.

Fine C, Lumsden J, Blair RJ. Institute of Cognitive Neuroscience and Department of Psychology, University College London, UK. There have been recent suggestions that the amygdala may be involved in the development or mediation of 'theory of mind'. We report a patient, B.M., with early or congenital left amygdala damage who, by adulthood, had received the psychiatric diagnoses of schizophrenia and Asperger's syndrome. We conducted a series of experimental investigations to determine B.M.'s cognitive functioning. In line with his diagnoses, B.M. was found to be severely impaired in his ability to represent mental states. Following this, we conducted a second series of studies to determine B.M.'s executive functioning. In the literature, there have been frequent claims that theory of mind is mediated by general executive functioning. B.M. showed no indication of executive function impairment, passing 16 tests assessing his ability to inhibit dominant responses, create and maintain goal-related behaviours, and temporally sequence behaviour. The findings are discussed with reference to models regarding the role of the amygdala in the development of theory of mind and the degree of dissociation between theory of mind and executive functioning. We conclude that theory of mind is not simply a function of more general executive functions, and that executive functions can develop and function on-line, independently of theory of mind. Moreover, we conclude that the amygdala may play some role in the development of the circuitry mediating theory of mind.

Furusho J, Matsuzaki K, Ichihashi I, Satoh H, Yamaguchi K, Kumagai K. Department of Pediatrics, School of Medicine, Showa University, 1-5-8 Hatanodai Shinagawa-ku, 142-8666, Tokyo, Japan An 8 year-old boy with Asperger's syndrome had difficulties in communicating with his teachers and classmates. He occasionally stole out of the classroom. He could not sleep at night recalling his awful experience and kept crying every night and refused to go to school. The treatment with fluvoxamine was started at the dose of 25 mg daily. Four weeks after the treatment, his repetitive behavior and hyperactivity decreased and night crying diminished. Although he still has difficulties in communicating with others, he is now able to attend extra-curricular classes in a private school. Fluvoxamine, a selective serotonin re-uptake inhibitor that has been mainly used for patients with depression and obsessive-compulsive disorder, might be effective for compulsive symptoms and sleep disturbance of patients with pervasive developmental disorders.

Nyden A, Billstedt E, Hjelmquist E, Gillberg C. Department of Child and Adolescent Psychiatry, Goteborg University, Sweden. Boys with Asperger syndrome (n=20), attention-deficit-hyperactivity disorder (n=20), and reading and writing disorder (n=20) were followed up and retested on several neuropsychological measures 1 to 2 years after initial assessments. Wechsler Intelligence Scale for Children (WISC-III) Full Scale, Verbal, and Performance IQ scores remained stable for all diagnostic groups. Kaufman factors and 'fluid' and 'crystallized' abilities were also stable measures. Subtest stability over time, was slightly more variable. There was a tendency for the group with Asperger syndrome to deteriorate over time with respect to logical reasoning abilities. Measures of executive function/attention ('go-no-go' and 'conflict' tests) showed good test-retest stability in all diagnostic groups. This is the first study of its kind.

The dopaminergic system, and in particular the dopamine D2 receptor, has been implicated in reward mechanisms. The net effect of neurotransmitter interaction at the mesolimbic brain region induces " reward " when dopamine (DA) is released from the neuron at the nucleus accumbens and interacts with a dopamine D2 receptor. " The reward cascade " involves the release of serotonin, which in turn at the hypothalmus stimulates enkephalin, which in turn inhibits GABA at the substania nigra, which in turn fine tunes the amount of DA released at the nucleus accumbens or " reward site. " It is well known that under normal conditions in the reward site DA works to maintain our normal drives. In fact, DA has become to be known as the " pleasure molecule " and/or the " antistress molecule. " When DA is released into the synapse, it stimulates a number a DA receptors (D1-D5) which results in increased feelings of well-being and stress reduction. A consensus of the literature suggests that when there is a dysfunction in the brain rew ard cascade, which could be caused by certain genetic variants (polygenic), especially in the DA system causing a hypodopaminergic trait, the brain of that person requires a DA fix to feel good. This trait leads to multiple drug-seeking behavior. This is so because alcohol, cocaine, heroin, marijuana, nicotine, and glucose all cause activation and neuronal release of brain DA, which could heal the abnormal cravings. Certainly after ten years of study we could say with confidence that carriers of the DAD2 receptor A1 allele have compromised D2 receptors. Therefore lack of D2 receptors causes individuals to have a high risk for multiple addictive, impulsive and compulsive behavioral propensities, such as severe alcoholism, cocaine, heroin, marijuana and nicotine use, glucose bingeing, pathological gambling, sex addiction, ADHD, Tourette's Syndrome, autism, chronic violence, posttraumatic stress disorder, schizoid/avoidant cluster, conduct disorder and antisocial behavior. In order to explain the breakdown of the reward cascade due to both multiple genes and environmental stimuli (pleiotropism) and resultant aberrant behaviors, Blum united this hypodopaminergic trait under the rubric of a reward deficiency syndrome.

The main project needing assistance at this time is the collecting of photographs of those of us in the spectrum for our picture display boards. The approx. 2 meters x 1 meter boards, each displaying 42 photos, are heartrending to say the least. They get attention and raise awareness when people see how very precious our kids are and how handsome our adults are. If you are in a country outside the United States and would like to work with us, please email me at Nancale@... and pass the word. All photos must be in photo print, not digital form. Each must be accompanied by a parental release form. _______________________________________________________ Lenny Schafer, Editor PhD Ron Sleith Kay Stammers Editor@...
