Folk concepts for mental disorder were studied among rural Lao people. While predominatly inferring etiology (e.g. spirit-caused disorder), certain terms also emphasized particular descriptive psychopathology or behavioral abnormality. Preventive strategies were stressed for insanity due to "excessive worry' or "broken taboo'. These broad folk categories of disorder bore considerable similarity to some psychiatric and neurologic categories within medicine. These includes psychosis, mania, neurosis, organic brain syndrome, mental retardation, cerebral palsy, epilepsy, and childhood autism. Lao folk terms for mental disorder also closely resembled those of other southern Asian cultures, although illiterate tribal peoples appeared to have fewer terms than literate peasant peoples. Folk terms from more distant regions had broad similarity to those of southeast Asia, but lacked the specificity found within the region.

The incidence of carbamazepine-associated behavioral side effects in 65 individuals with mental retardation and additional seizure and/or psychiatric or behavioral disorders was evaluated. We identified 6 patients (9.2%) who experienced medication side effects, ranging from irritability to mania. Four of the 20 patients (20%) who received carbamazepine purely for treatment of a behavioral or psychiatric disorder experienced medication side effects, whereas none of the 21 patients treated for an isolated seizure disorder experienced similar effects. This difference was statistically significant, p less than .05. The incidence of behavioral side effects of medication was not associated with age, sex, or serum carbamazepine level. The chemical structure and mechanism of carbamazepine use in various disease processes were discussed.

Twenty-five published reports were reviewed regarding the occurrence of affective illness, ie, depression and mania, in mentally retarded individuals, using the DSM-III criteria to assess the validity of both diagnoses. Individuals with mental retardation (MR) were found to manifest the full range of affective disorders. Developmentally impaired social functioning and intelligence influence the clinical presentation, but not the development, of affective symptomatology. Affective disorder diagnoses can be made for patients with all levels of MR severity. In individuals with MR of mild and moderate severity, the diagnosis can be made using standard DSM-III criteria. For those with severe and profound MR, a clinically useful diagnosis can be based on changes in behavior and vegetative functioning, as well as family history of affective illness. The psychiatrically symptomatic person with MR should always be evaluated for affective symptomatology and be considered as a candidate for the full range of treatments, including psychotherapy and pharmacotherapy with antidepressants as well as lithium carbonate.

The purpose of this paper is to provide psychiatrists with practical advice on how to detect malingered mental illness. Various types of malingering are defined and the five major purposes of malingering are specified. The research literature on malingering is reviewed. Clinicians must be thoroughly grounded in the phenomenology of true mental disease to detect malingering. Detailed information about hallucinations is reviewed so that faked hallucinations that do not follow typical patterns can be more easily identified. Strategies for approaching persons suspected of malingering are suggested. Features of malingered mutism, mania, depression and mental retardation are described. The differential diagnosis of malingering, post-traumatic stress disorder, conversion disorder, and post-concussion syndromes after trauma is discussed. Clues to malingered psychoses and post-traumatic stress disorders are delineated. Finally, specific indicators of malingered insanity defenses are identified.

A survey of affective symptoms in two groups of institutionalized adults with mental retardation was conducted. The groups were comprised of subjects with prior diagnoses of affective disorders or other psychiatric disorders. Informants reported retrospectively on the presence or absence of DSM-III-R criteria for major depression and mania. Thirteen percent of the affective disorders group did not meet these criteria for depression or mania, whereas 20% of the other psychiatric disorders group did. Aggression was a frequent concomitant of psychopathology in both groups. These findings support previous reports that affective disorders may be underdiagnosed in this population. However, unlike prior investigations, most of the subjects (74%) in the present survey had severe to profound mental retardation.

As the new generation of atypical antipsychotics becomes available, the limitations of the older typical agents become apparent. The new medications, which have benefits other than the alleviation of positive symptoms of schizophrenia, may also be beneficial for psychotic disorders that have responded poorly to conventional neuroleptics. This article will describe the potential use of the atypical antipsychotics, especially olanzapine, for affective mood disturbances in schizophrenia, psychotic depression and mania, first-break schizophrenia, comorbid schizophrenia and substance abuse disorders, dementia in the elderly and those with late-onset schizophrenia, and behavioral problems in patients with mental retardation or developmental delays.

There is a now a substantial body of evidence that suggests the new antipsychotic agent, risperidone, may be safe and effective for treating psychotic, affective or behavioural symptoms associated with various disorders other than schizophrenia, schizophreniform disorder or schizo-affective disorder. These conditions include bipolar disorder, obsessive-compulsive disorder, Tourette's syndrome, dementia, Lewy body disease, mental retardation, Parkinson's disease, idiopathic segmental dystonia and organic catatonia. Although much of the data is anecdotal or in the form of open studies, there is now emerging a small number of well controlled investigations supporting efficacy for mania, dementia, behavioural disturbance in mental retardation and conduct disorder. Conventional antipsychotics have long been used, either in a primary capacity or as an adjunct to treat these disorders; however, they have limited benefit, pose significant risks of extrapyramidal side-effects, and may cause the potentially life-threatening neuroleptic malignant syndrome. In contrast, risperidone at the recommended low doses may be efficacious and pose reduced risk of motor side-effects. This article reviews the evidence that risperidone may be an effective new treatment for disorders other than schizophrenia.

An abbreviated version of the Minnesota Multiphasic Personality Inventory, the MMPI-168(L), modified for use with clients who have moderate or mild mental retardation, was administered to 58 clients, most of whom had co-existing dual psychiatric diagnoses. Another recently developed instrument, the Assessment of Dual Diagnosis (ADD), was administered by interviewing a knowledgeable care giver. Correlations were examined among the raw scores on the 13 ADD scales and T scores of the 13 MMPI-168(L) scales. Contrary to expectations few correlations were found between the scales of the two instruments including scales purported to assess similar psychological constructs. The major exception was the Mania scale of the MMPI-168(L), which correlated moderately well with the Schizophrenia and Dementia scales of the ADD. Client age correlated strongly and negatively with scores on the Conduct Disorder and Sexual Disorder scales of the ADD. Finally, intra-instrument scale correlations were surprisingly large and, from a clinical and diagnostic perspective, meaningful. However, the large number of intra-instrument correlations showed that the scales of both instruments possess considerable overlap, which could make differential diagnosis problematic. It is suggested that it might be necessary to administer both instruments, and carefully consider behavioral history, to accurately diagnose psychiatric disturbances or personality characteristics of individuals with mental retardation.

Interactions between brain, psyche and thyroid are known from historical descriptions of thyroidectomy (Kocher) and hyperthyroidism. However, their importance is often underscored in clinical routine. Thyroid hormone deficiency during pregnancy may result in irreversible mental retardation and requires levothyroxine substitution. TSH screening after delivery must identify newborns with congenital hypothyroidism: An early levothyroxine substitution and long term therapy control are required. Hypothyroidism and depression have many symptoms in common. Cognitive deficits and depressive states are often found in overt hypothyroidism, psychotic derangements are rare. Levothyroxine improves hypothyroid symptoms and mental performance, mood and motivation. Psychic symptoms of hyperthyroidism include agitation, irritability, mood disturbances, hyperactivity, anxiousness and even panic attacks. Manic and delusional states are rare. In geriatric patients hyperthyroidism may be oligosymptomatic. In psychiatric patients more frequent but unspecific disturbances of thyroid laboratory values being reversible without specific therapy have to be distinguished from rather rare but causative organic thyroid diseases with therapeutic consequences. Some psychiatric drugs influence thyroid laboratory results. Hypothyroidism in depressive patients is a negative prognostic parameter and requires therapy. Psychiatric symptoms associated with hypothyroidism are usually reversible under levothyroxine within 4-8 weeks. The standard for hypothyroidism is mono-levothyroxine therapy.

Research examining the role of pharmacological therapy in the treatment of children and adolescents with clinical disorders is growing. Clinical disorders that present with comorbid aggression can add a challenge to treatment. Child and adolescent neuropsychiatric disorders associated with aggression include attention-deficit hyperactivity disorder, various mood disorders and in particular bipolar disorders/pediatric mania, schizophrenia, mental retardation, oppositional defiant disorder, conduct disorder, and autism spectrum disorders. This review describes the psychopharmacy to treat these disorders and the aggression that often appears comorbidly. Existing literature regarding the efficacy and safety of psychotropics for youth with neuropsychiatric disorders also is discussed. In addition, general guidelines for psychopharmacy of aggression in children and adolescents are presented. Studies reviewed in this article provide evidence for the use of psychostimulants, alpha-2 agonists, beta blockers, lithium, anticonvulsant mood-stabilizers, atypical antipsychotics, traditional antipsychotics, and selective serotonin reuptake inhibitors in treating pediatric aggression with the choice of medication dependent on symptomology. Despite increased support for pediatric psychotropic use, there is a need for more long-term safety and efficacy studies of existing medications and newer, safer, and more effective agents with fewer side effects for the pharmacological treatment of all childhood disorders in which aggression is prominent.
