We tested whether dimensional measures of empathic ability, theory of mind, and intelligence would differentiate autism spectrum disorders from each other and from non-spectrum disorders. Tests were administered to children with a diagnosis of Autistic Disorder (AutD; n = 20), Asperger's Disorder (AspD; n = 28), Attention Deficit/Hyperactivity Disorder (Inattentive Type) (ADHD; n = 35), Mental Retardation (Mild) (MR; n = 34), Anxiety Disorder (AnxD; n = 14), or No Psychological Disorder (NPD; n = 36). Results showed that empathic ability discriminated among groups on the autism spectrum (AutD < AspD < NPD). Because empathic ability is not independent of intelligence (AutD < AspD < NPD on intelligence; MR < ADHD < NPD on empathic ability), both dimensions are necessary to discriminate autism spectrum from non-spectrum disorders. When intelligence is covaried, empathic ability discriminated AutD, but not AspD, from other disorders (AutD < MR < ADHD < NPD = AnxD = AspD).

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.

In this paper we review the aspects linked with the comorbidity of attention deficit hyperactivity disorder (ADHD). The disorders most frequently associated with ADHD are: Tourette syndrome, generalised development disorders, communication disorders, learning disorders, coordination development disorders, behavioural disorders, anxiety disorders, affective disorders and mental retardation. From the neurocognitive point of view, the executive functions play an important role in ADHD and from the neuroanatomical point of view there is involvement of the frontostriatal circuits. The functional model of ADHD based on these functions and these structures enables us to understand the comorbidity with the above mentioned processes. Given the high rate of comorbidity of ADHD it is important to identify the associated problems in order to rationalise the psychological approach and pharmacological treatment employed. We also review the therapeutic implications that comorbidity entails.

Although much research has focused on the cognitive-linguistic profile associated with Williams syndrome, studies have yet to follow up on preliminary observations suggesting increased anxiety and fears in persons with this disorder. To this aim, Study 1 compared fears in 120 participants with Williams syndrome to 70 appropriately matched persons with mental retardation of mixed etiologies. Study 2 assessed differences in parent versus child reports of fears in 36 Williams syndrome and 24 comparison group parent-child dyads. In Study 3, rates of phobia and other anxiety disorders were assessed in standardized psychiatric interviews with the parents of 51 individuals with Williams syndrome. Relative to their counterparts, persons with Williams syndrome had significantly more fears as well as a wider range of frequently occurring fears, as reported by either parents or participants themselves. Children in both groups reported more fears than their parents. Whereas generalized and anticipatory anxiety were found in 51% to 60% of the sample with Williams syndrome, specific phobia was more prevalent, with 96% showing persistent and marked fears and 84% avoiding their fears or enduring them with distress. The feasibility of cognitive-behavioral treatments for phobia is discussed, as are implications for future research.

After literature review, this paper presents the largest study to date (n = 270) of psychiatric and neurological characteristics of accused murderers in the United States. This retrospective record review of pretrial detainees undergoing competency to stand trial and criminal responsibility evaluations examined demographic characteristics, psychiatric diagnosis, substance use patterns, Intelligence Quotient (IQ), and results of electroencephalogram (EEG), neuroimaging (MRI or CT) and neurological examination. Substance use and mood/adjustment disorders were common. Neuroimaging was abnormal in 18% of subjects and was associated with lower Performance IQ. EEG and neurological exam findings were not associated with measured cognitive impairment. While 16% of subjects had a FS IQ < 70, only 6% were diagnosed with mental retardation. Subjects with a psychotic disorder (p = 0.001) or an anxiety disorder (p = 0.005) were more likely to use a knife than other subjects in the study. Violence risk assessment in these patients must not only involve inquiry about firearm availability.

Fragile X syndrome is the leading inherited form of mental retardation, and second only to Down's syndrome as a cause of mental retardation attributable to an identifiable genetic abnormality. Fragile X syndrome is caused by a defect in the fragile X mental retardation 1 gene (FMR1), located near the end of the long arm of the X chromosome. FMR1 normally synthesises the fragile X protein (FMRP), but mutations in FMR1 lead to a lack of FMRP synthesis, resulting in fragile X syndrome. While the specific function of FMRP is not yet fully understood, the protein is known to be important for normal brain development. The physical, cognitive and behavioural features of individuals with fragile X syndrome depend on gender (females have two X chromosomes, one active and one inactive) and the molecular status of the mutation (premutation, full mutation or mosaic). Features of the behavioural profile of individuals with fragile X syndrome include hypersensitivity to stimuli, overarousability, inattention, hyperactivity and (mostly in men) explosive and aggressive behaviour to others or self. Social anxiety, other anxiety disorders, depression, impulse control disorder and mood disorders are the most common psychiatric disorders diagnosed in individuals with fragile X syndrome, although no formal studies have been undertaken. There have been very few psychopharmacological studies of the treatment of behaviours associated with fragile X syndrome. These limited studies and surveys of psychotropic drugs used in individuals with fragile X syndrome suggest that stimulants are helpful for hyperactivity, that alpha(2)-adrenoceptor agonists and beta-adrenoceptor antagonists help to control overarousability, impulsivity and aggressiveness, and that SSRIs can control anxiety, impulsivity and irritability, alleviate depressive symptoms and decrease aggressive and self-injurious behaviour. Typical and atypical antipsychotics in combination with other psychotropics have been used for control of psychotic disorders and severe aggressive behaviours. Mood stabilisers have been found to be useful when mood dysregulation or mood disorders are present with or without aggressive behaviour. Folic acid and L-acetylcarnitine (levacecarnine) have not been found to improve deficits or behaviours. As there is no specific psychotropic drug for any of the deficits or behaviours associated with fragile X syndrome, clinicians are advised to diagnose any psychiatric syndromes or disorders present and treat them with the appropriate psychotropic drug. If no psychiatric disorder can be diagnosed and the patient's challenging behaviours cannot be controlled with environmental manipulation or behaviour modification techniques, the most benign psychotropic drug should be used. Antipsychotics should be reserved for psychotic disorders, for impulse control disorders (used in combination with other psychotropics), or when challenging behaviours constitute an emergency. In the future, new medications targeting molecules implicated in the modulation of anxiety, fear and fear responding will be useful for treating the social anxiety and overarousability exhibited by individuals with fragile X syndrome.

Knowledge of current patterns of psychotropic medication use by disabled youths is an important starting point for targeting future efforts to improve prescribing practices. This study provides a retrospective, descriptive analysis of the prevalence and patterns of psychotropic medication among 1022 Kansas Medicaid youths in 2001 who were enrolled with either Supplemental Security Income (SSI) or Medically Needy benefits and who were having clearly defined mental and neurological disabilities. Rates of psychotropic medication use were generally higher for the Medically Needy than for the SSI youths: Central nervous system (CNS) stimulants (24.6% versus 20.0%), antidepressants (30.9% versus 13.7%), anticonvulsants (22.0% versus 13.9%), and antipsychotics (23.3% versus 11.5%). Use of the four major drug classes varied among children with attention-deficit/hyperactivity disorder (ADHD) and disruptive disorders, pervasive developmental disabilities, mental retardation (MR) and learning disabilities, mood and anxiety disorders, and adjustment disorders. Future work should explore the appropriateness and effectiveness of these medications within specifically targeted subgroups.

This study was undertaken to identify psychiatric morbidity among Korean second and third elementary school children using an objective diagnostic interview tool. Data from 5,118 (2,723 boys, 2,395 girls; mean age = 8.41 years (SD = 0.66)) second and third grade schoolchildren were drawn from 28 elementary schools. After initial screening assessments using the 28-item Child Problem-Behavior Screening Test for parents, 672 primary caregivers were subjected to secondary screening using the Korean version of the CBCL. Two hundred and seventy-one high-risk children selected according to the K-CBCL results, 138 (50.9%) children and their primary caregivers were interviewed using the Korean version of K-SADS-PL for objective DSM-IV psychiatric diagnoses. Sixty-four (46.4%) of the hundred and thirty eight children were determined to have at least one psychiatric disorder. More boys were diagnosed as psychiatric patients than girls (46 males, 18 females; OR = 2.21). The most frequently diagnosed disorder was ADHD (46/64; 71.9%), followed by tic disorder, anxiety disorders, mental retardation, oppositional defiant disorder, and separation anxiety disorder. Two or more comorbid psychiatric disorders were found in 22 (34.4%) of the 64 patients. The computed crude percentage of psychiatric patients in this study was 4.12%, which is similar to previously published data.

A total of 283 patients with somatoform disorder (SFD) seen in a psychiatry clinic were surveyed and their diagnostic subtypes, demographic features, and comorbidities, analyzed. The results indicate that: (i) SFD comprises 5.8% of first-visit outpatients; (ii) undifferentiated SFD (USFD) and SFD not otherwise specified (SFD-NOS) account for the majority of patients; (iii) there are 1.7-fold more women than men; (iv) age of onset is lower in patients with somatization disorder or body dysmorphic disorder and higher in patients with hypochondriasis or pain disorder; (v) the mean number of years of education was 11.2 years; and (vi) comorbid illness were seen in 24.8% of patients, and included mood disorder, anxiety disorder, and personality disorder, as well as borderline intellectual functioning and mental retardation. The data indicate that the majority of patients with SFD are given a diagnosis of residual category, such as USFD or SFD-NOS, and that the age of onset varies depending on the diagnostic subtype. SFD was more frequently seen in women, associated with comorbidities.

Fragile X syndrome is, after Down's syndrome, the most common form of mental retardation. Women are potential carriers and can have the defective gene on one of their two X chromosomes without developing the complete syndrome. In this paper we examine which psychiatric disturbances may appear or develop in women because they are carriers of the fragile X mutation. Carriers have been found to have a higher frequency of anxiety disorders, affective disorders and schizotypal features.
