Methods: This was a cross sectional study with control group. Case was defined as adolescents with antipsychotic-treated schizophrenia without any mental retardation or other physical illnesses (n=45).

Neuroimaging markers for the prediction of treatment response to Methylphenidate in ADHD.

Background: Attention Deficit Hyperactivity Disorder (ADHD) is one of the most prevalent mental disorders of childhood, which often continues into adulthood. Methylphenidate is one the most commonly used medication to treat ADHD, however up to 30% of patients do not respond to it.

Aims: This paper aims to review studies, which employed neuroimaging to predict treatment response to Methylphenidate in ADHD.

Ijime in Japan.

This paper reviews the problem of ijime in Japan from a variety of perspectives, primarily through studies conducted in this country. The term ijime is not uniform in concept, open to different interpretations given the disparity in definitions among different circles, making precise assessment of the actual conditions difficult. Such being the case, what is needed is further study on the mechanisms and actual state of ijime accounting for the flow of the times, and compilation of research to enable the creation of ever more effective modes of prevention and intervention.

[The neurotic disorders].

The clinical practice of child and adolescent psychiatry includes encounters with disorders not particular to childhood and adolescence, but seen in adulthood as well. For example, among the neurotic disorders, obsessive-compulsive disorder can be seen from around 3 years of age, with rapid rise in prevalence from around age 10. Increase is also seen in cases of anorexia nervosa from around age 11.

Prefrontal overactivation, autonomic arousal, and task performance under evaluative pressure: a near-infrared spectroscopy (NIRS) study.

To study the mechanism underlying the influence of psychological pressure on task performance, we investigated the relationship between prefrontal activation, autonomic arousal, and performance in an n-back working memory task with 3 load levels (l-, 2-, and 3-back tasks) under evaluative pressure. The tasks were performed by 32 university students with or without evaluative observation by experimenters. The error rate and prefrontal activation were found to increase with pressure only in the highest load task (3-back).

Hemodynamic changes in the prefrontal cortex during digit span task: a near-infrared spectroscopy study.

Background/aims: In this study, we examined changes in the concentrations of oxygenated and deoxygenated hemoglobin (oxy- and deoxy-Hb, respectively) in the prefrontal cortex (PFC) during the digit span task by using near-infrared spectroscopy (NIRS).

Methods: The digit span task consists of the digit span forward and backward tasks. The tasks were performed by 22 healthy undergraduate students who participated in this study.

Personality and defense mechanisms in late adulthood.

Objective: Current understanding of the use of psychological defense mechanisms (DMs) in older adults is limited. This study set out to examine individual differences in DMs and Cloninger's biosocial model of personality in two age groups (50-64, 65-93), as well as their influence on health.

Methods: A Japanese community sample (N = 330) completed the Temperament and Character Inventory (TCI-125), the Defense Style Questionnaire (DSQ-40), and the General Health Questionnaire (GHQ-28).

Application of the Revised Infant Temperament Questionnaire for evaluating temperament in the Japanese infant: creation of an abridged Japanese version.

The Japanese version of the Revised Infant Temperament Questionnaire (RITQ) was implemented to re-evaluate factor structure of the temperament scale with the objective of simplification. The questionnaire was conducted on 1099 mothers of Japanese infants visiting health centers for their children's health examinations at 6 or 7 months. As a result, a 57-item abridged version was constructed consisting of the seven subscales: 'fear of strangers and strange situations', 'insensitivity to food', 'regularity of rhythm', 'manageability', 'activity level', 'persistence of attention', and 'insensitivity to touch'.

Regional brain cerebral glucose metabolism and temperament: a positron emission tomography study.

Personality, and in particular temperament, is thought to have a biological basis. In the present study, the relationships between regional brain glucose metabolism and temperament have been investigated. Regional brain glucose metabolism was measured using [18F] fluorodeoxyglucose positron emission tomography in 31 healthy subjects.

No association between monoamine oxidase A promoter polymorphism and personality traits in Japanese females.

Monoamine oxidase A (MAO-A) is an enzyme involved in the metabolism of monoamine neurotransmitters such as dopamine, serotonin, and noradrenaline in the brain. Previous studies have demonstrated a significant association between MAO-A gene polymorphism and personality traits in males. The purpose of the present study was to examine this association in females.

Transient eating disorder in early childhood--a case report.

Although children in infancy present eating problems of multifarious nature, the diagnostic classification of infant eating disorders remains markedly deficient. The authors present a case exhibiting transient eating disorder in early childhood, alongside discussion of some considerations relevant to this age group. The subject was a boy aged 5 years 6 months at first presentation.

Hallucinatory experiences in a community sample of Japanese children.

Objective: Hallucinatory experiences in children are often thought to indicate serious psychopathology. However, they have also been reported in normally developing children and in association with temporary psychological reactions to acute stress. The aim of this study was to investigate the prevalence of hallucinatory experiences in a nonclinical population of children and to examine the relationship between the modality and content of hallucinations and psychopathology.

[Support for the family from infancy].

A rising tendency has been reported for child abuse in our country in recent years, and the need to provide support for child-care capabilities in the home has been raised. In this context, attention has turned to the mother-child relationship and the mother's mental health from early on, in pregnancy and the antenatal period. In particular, it has become clear that the incidence of post-partum maternity blues and puerperal depression is higher than hitherto believed, drawing focus upon the effects of the mother's depression on the mother-child relationship.

Antenatal depression and maternal-fetal attachment.

Background: In recent years, attention has been turned to maternal mental health in relation to the mother-child relationship accompanying a widening in focus, i.e. taking into account not only the puerperium, but also the stage of pregnancy.

Study on feelings of school avoidance, depression, and character tendencies among general junior high and high school students.

School refusal is a phenomenon that first drew attention in Japan around 1960 and it remains one of the major issues in child psychiatry today. Moreover, it is now said that there exists a large group of latent school refusers currently attending school but harboring feelings of school avoidance. To address this issue, a questionnaire survey was conducted on students enrolled in a junior high and high school affiliated with the Nagoya University School of Education.

Depression in the mother and maternal attachment--results from a follow-up study at 1 year postpartum.

Although evidence exists pointing to the impact of maternal depression in puerperium upon mother-child interaction, longitudinal studies on this perspective are rare. Hence, this study was designed to examine the association between maternity blues and maternal attachment in the puerperium with depression in the mother and attachment after 1 year together with the factors involved. A questionnaire survey consisting of Zung's Self-Rating Depression Scale (ZSDS) and a 'maternal attachment' scale, comprised of subscales on 'core maternal attachment' and 'anxiety regarding children', was conducted on mothers who had participated in a previous puerperium survey.
