The frequency and clinical presentation of autism in 28 probands with tuberous sclerosis complex (TSC) are reported and risk factors that may influence the development of autism in TSC are examined. Eight probands meet ICD-10 and DSM-IV criteria for autism, an additional 4 meet criteria for pervasive developmental disorder (PDD). Twelve TSC probands with autism/PDD are compared to 16 TSC probands without these conditions for factors which may underlie the association of autism and TSC. A specific seizure type, infantile spasms, as well as mental retardation, are increased in the TSC, autistic/PDD group. Furthermore, rates of social phobia and substance abuse are elevated among first-degree relatives of TSC probands with autism compared to first-degree relatives of TSC probands without autism. Implications of these findings in understanding the association of autism and TSC are discussed.

Variations of season of birth among autistic individuals were studied. The replicability of previously reported increases in birth rates in the months of March and August were examined in groups of individuals with autism or mental retardation (the comparison group). The sample was obtained from the Yale Child Study Center Developmental Disabilities Clinic and from the DSM-IV Autism/PDD field trial. Data were analyzed by applying the Jonckheere test of ordinal trend and the chi-square test, with Yates correction factor. With respect to March and August births, and with calculations based on the beginning and middle of the month, no significant seasonal effect was observed. Samples were subcategorized into verbal and mute groups, and again results failed to support the seasonality hypothesis.

Smith-Lemli-Opitz syndrome (SLOS, RSH/SLO syndrome, MIM 270400) is an autosomal recessive multiple malformation/mental retardation syndrome initially described by Smith et al. [1964] that is due to a defect in cholesterol biosynthesis. The behavioral phenotype of Smith-Lemli-Opitz syndrome demonstrates cognitive abilities from borderline intellectual functioning to profound mental retardation, sensory hyperreactivity, irritability, language impairment, sleep cycle disturbance, self-injurious behavior, and autism spectrum behaviors. In a recent study of 28 subjects, 14 subjects (50%) with SLOS also exhibited the behavior of throwing themselves backward in a characteristic upper body movement ("opisthokinesis") and 2 adolescents had a stretching motion of the upper body accompanied by hand flicking [Tierney et al., 1999]. In that same study, 6 of 13 subjects (46%) met the Autism Diagnostic Interview-Revised (ADI-R) algorithm criteria (Lord et al. [1993] Infant Mental Health 14:234-252; Lord et al. [1994] J Autism Dev Disord 24:659-685) and the Diagnostic and Statistical Manual (APA [1994] DSM-IV) diagnostic criteria for autistic disorder. Smith-Lemli-Opitz syndrome is a metabolic disorder that is associated with autism. MRDD Research Reviews 2000;6:131-134.

This is a review of pharmacotherapy in children and adolescents with mental retardation from the perspective of DSM and ICD disorders. The existing research is reviewed in young people with mental retardation but, when data are lacking, we examined the literature from adults with mental retardation and from typically-developing children. The literature is discussed for each of the following disorders: ADHD, anxiety disorders, bipolar disorder, conduct disorder, depression, enuresis, schizophrenia, self injury, and tics and movement disorders. With the possible exception of ADHD, there is a woeful lack of empirical data on most of these disorders in young people with mental retardation. Clinicians will often be forced to extrapolate from data on adults having mental retardation and from typically-developing children. The best policy is probably to treat such patients cautiously, while gathering data on the effects of such therapy in the hopes of beginning a data base.

Infant psychiatry is a discipline concerned with diagnostic assessment, treatment, and prevention of mental health problems in infancy and early childhood. A new diagnostic framework: Zero to three (DC 0-3) has been designed to complement the ICD 10/DSM IV, including new diagnostic categories, and a multiaxial construct addressing developmental and relational aspects. Prevalence and outcome for mental retardation and pervasive developmental disorders are well known. Our knowledge of variations in attachment patterns, disorders of neurophysiological regulation, eating disorders, failure to thrive, emotional, affective, and behavioural problems, disorders of relating and communication, and eventually parent-child relationship disorders is still incomplete. It is recommended to use video and combine clinical evaluation with structured tests in assessment. Intervention may include guidance, psychoeducation, psychotherapy, as well as social and educational support. Parent-child relationship treatment seems effective. Evaluating intervention and treatment raises immense methodological problems. Future research should address how risk and resilience interacts in the psychopathological process and enhance our knowledge of effective intervention strategies.

This study describes the outcome of a token economy treatment applied to 2 distinct patient populations on the same unit of a state psychiatric hospital: individuals with a dual diagnosis of mental retardation and a DSM-IV Axis I diagnosis of either (a) a severe behavior disorder (BD) or (b) a serious and persistent psychiatric disorder (PD). Results showed that patients in the PD group were more likely to complete the treatment (17/20) than those in the BD group (17/31) who were more likely to be terminated from the program (14/31). Individuals who did not complete the program were distinguished early, within the first 3 weeks of treatment. These noncompleters received significantly more fines and earned significantly fewer tokens than those who completed the program. At an average of 2.7 years post-discharge, there was no difference in the proportion of PD (12/16) and BD completers (9/11) and BD noncompleters (3/7) remaining in the community. These data show that diverse populations of patients can be treated within the same token economy program, thereby improving cost effectiveness. Future research should be directed toward characterizing those patients (e.g., BD) less likely to succeed when they enter treatment, and determining if modifications in the program can improve that outcome.

Attention deficit hyperactivity disorder (ADHD) is a highly heritable, common psychiatric disorder that presents in childhood and that probably involves several genes. There are several lines of evidence suggesting that the nicotinic system may be functionally significant in ADHD: (a) nicotine promotes the release of dopamine and has been shown to improve attention in adults with ADHD, smokers and non-smokers; (b) ADHD is a significant risk factor for early initiation of cigarette smoking in children; (c) maternal cigarette smoking appears to be a risk factor for ADHD; (d) animal studies in rats and monkeys also suggest that nicotine may be involved in attentional systems and locomotor activity; and (e) a central nicotinic agonist, ABT-418, improves attention in both monkeys and ADHD adults. The current study examined the alpha 4 receptor, one of the sites of action of ABT-418. A known Cfol polymorphism within the nicotinic acetylcholine alpha 4 receptor gene, CHRNA4, was studied in 70 ADHD parent-proband trios from an ongoing sample collection of children aged 6-12 with ADHD, according to DSM-IV criteria. Children with known major medical or psychiatric conditions or mental retardation (IQ < 70) were excluded from the study. The Transmission Disequilibrium Test demonstrated no evidence that variation at the nicotinic acetylcholine alpha 4 receptor Cfol polymorphism influences susceptibility to ADHD (P > 0.35). The continuing sample collection will enable further study of other potential nicotinic system polymorphisms in ADHD in more powerful samples.

To find the prevalence of 8 mental disorders and study knowledge, attitude, practice (KAP) upon mental health among people in Bangkok Metropolis a cross sectional, descriptive community survey was conducted. Two thousand, nine hundred and forty eight samples aged 15-60 years were selected by a multistage simple random sampling technique. Data collection was made by qualified interviewers who had experience in mental health care and had been trained to use the questionaires. The questionaires had been modified from DSM-IV and CIDI that had been tested for good validity and reliability. The survey methodology was divided into 2 stages, screening and diagnosis. The results showed that the life time prevalence of mental disorders were; schizophrenia (1.3%), mood disorders; manic episode (9.3%), major depressive episode (19.9%), dysthymia (1%), anxiety disorders (10.2%), mental retardation (1.8%), epilepsy (1.3%), suicidal idea (7.1%), drug and substances use disorders (11.2%), and alcohol use disorders (18.4%). Knowledge score was good, attitude was fairly good, practice was still weak in promotion and prevention aspects. As such, this study was used as a pattern to conduct a national survey in 14 provinces all over Thailand and the results are being summarized. The information is similar to the Global Burden of Diseases. We produced a national training program on "Detection and Management of Depression" for Primary Care Physicians that was, a 2 days' workshop. Other national programs promoting prevention and control have also been set up.
