Pervasive developmental disorder is one of the most severe clinical disorder in child psychiatry and is associated with deviancies in multiple areas of development. Medication does not cure pervasive developmental disorder and its effectiveness is generally nonspecific. But psychopharmacological treatment can be important for some children with pervasive developmental disorder and can make many young autistics more amenable to behavior modification and education. Haloperidol, the most widely studied antipsychotics, was statistically and clinically superior to placebo, and furthermore, was known to facilitate the positive functioning such as, discrimination learning and imitative communication, without side effects. However, administration of haloperidol is associated with drug related dyskinesia, and it warrants the introduction and use of the other novel drugs. Several biochemical studies suggest that subgroups of children with pervasive developmental disorder show hyperserotonemia and increased endogenous opioid level as compared with controls. Psychopharmacological trials were conducted according to these findings(ex : fenfluramine, naltrexone), with mixed results till now. These and another drugs that have been used in children with pervasive developmental disorder and their effectiveness are reviewed.

In this paper, we propose accurate classification method of an EEG signals during a mental tasks. In the experimental task, subjects achieved through the process of responding to visual stimulus, understanding the given problem, controlling hand motions, and select a key. To recognize the subjects' selection time, we analyzed with 4 types feature from the filtered brain waves at frequency bands of $\alpha$, $\beta$, $\theta$, $\gamma$ waves. From the analysed features, we construct specific rules for each subject meta rules including common factors in all subjects. In this system, the architecture of the neural network is a three layered feedforward networks with one hidden layer which implements the error back propagation learning algorithm. Applying the algorithms to 4 subjects show 87% classification success rates. In this paper, the proposed detection method can be a basic technology for brain-computer-interface by combining with discrimination methods.

It is widely known that individuals with mental retardation (MR) and Down's syndrome (DS) often develop early onset periodontal diseases. In this study, the prevalence of periodontopathic bacteria in MR persons and DS patients was compared with normal persons. Plaque index and gingival index were measured. Five periodontopathic bacteria, Actinobacillus actinomycetemcomitans. Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Fusobacterium nucleatum were surveyed in subgingival plaque samples by the polymerase chain reaction. Results : 1. Plaque index and gingival index were higher in MR persons group and DS patients group than normal persons group (p<0.05). 2. The prevalence of periodontopathic bacteria in normal persons group were lower than that of MR persons group and DS. Significant differences were observed in the prevalence of P. gingivalis, T. denticola and A. actinomycetemcomitans(P<0.05). 3. Prevalence of P. gingivalis(5.9%) at age 8-10 was lower than other ages in normal persons group, and its prevalence increased with age Prevalence of P. gingivalis, T. denticola and A. actinomycetemcomitans at MR persons group and DS patients group were higher than those of same ages of normal persons group. 4. Plaque index was associated with T. denticola and gingival index was associated with T. denticola and A. actinomycetemcomitans(P<0.05). These results suggested that plaque index, gingival index and prevalence of periodontopathic pathogens, especially P. gingivalis, T. denticola and A actinomycetemcomitans in DS patients group and MR persons group are higher than those of normal persons group.

Pain can be evaluated by experimental methods and clinical methods, but due to subjective characteristics of pain, clinical methods are generally used. The clinical pain measurement tools are divided into unidimensional and multidimensional assessment tools. The former include Visual Analogue Scale, Verbal Rating Scale, Numerical Rating Scale, Pain Faces Scale, and Poker Chip Tool and the latter include McGill Pain Questionnaire, MMPI, Pain Behavior Scale, Pain disability index, and Pain Rating Scale. Unidimensional pain scales mainly measure the intensity of pain on the basis of the patient's self report and their simple construction and ease of use enable the invesgator to assess acute pain. Multidimensional pain scales are used to evaluate subjective, psychological and behavioral aspects of pain and because of its comprehensive and confidential properties they are applied to chronic pain. Patient's linguistic and cognitive abilities are major factors to restrain accurate assessment of pain. Although behavioral patterns and vital sign are inferior to self-report in the measurement of pain, they can be useful indexes in those situations. When deciding on a pain-assessment tool, the investigator must determine which aspect of pain he or she wishes to evaluate on the characteristics of the group of patients, their backgrounds, and their communication skills. Making the proper choice will facilitate the acquisition of meaningful data and the formulation of valid conclusions.

In an open labeled study, two fixed doses of nimodipine(45mg and 90mg daily) were added to the usual antipsychotic drug treatment (Haloperidol : mean dose=25mg/day) in 20 male chronic schizophrenics for 5 weeks. The purposes of this study were to evaluate the therapeutic effects and the effect an the changes of plasma homovanillic acid(HVA) and 5-hydroxyindoleacetic acid(5-HIAA) levels. The results were as follows : 1) Total BPRS score and thought cluster, paranoid cluster subscores showed linear decreasing trend over the course of the study(P<0.05). Especially the thought cluster and paranoid cluster subscores were significant difference between 45mg and 90mg dose of nimodipine(P<0.05). The improvement rates were 45,45% of 90mg and 11.11% of 45mg, but there was no significant difference between the 45mg and 90mg dose of nimodipine. 2) The scores of extrapyramidal symptoms and adverse events-somatic symptoms showed a linear decreasing trends over the course of study. 3) The changes in the mean plasma HVA and 5-H1AA concentrations by the dosages and durations of combining of nimodipine were not statistically significant. 4) There was no statistical significance in plasma HVA and 5-HIAA of the improved, non-improved goroup. Nimodipine has a possibility os on adjunctive agent for treatment resistant schizophrenics, elderly patients and liable patients for the Side effects to usual antipsychotic drugs. So we suggest that the dosage of nimodipine must be above 90mg/day in the treatment of schizophrenia.

Virtual Reality(VR) is a new technology which makes humans communicate with computer. It allows the user to see, hear, feel and interact in a three-dimensional virtual world created graphically. In this paper, we introduced VR into psychotherapy area and developed VR system for the exposure therapy of acrophobia. Acrophobia is an abnormal fear of heights. Medications or cognitive-behavior methods have been mainly used as a treatment. Lately the virtual reality technology has been applied to that kind of anxiety disorders. A virtual environment provides patient with stimuli which arouses phobia, and exposing to that environment makes him having ability to over come the fear. In this study, the elevator stimulator that composed with a position sensor, head mount display, and audio system, is suggested. To illustrate the physiological difference between a person who has a feel of phobia and without phobia, heart rate was measured during experiment. And also measured a person's HR after the virtual reality training. In this study, we demonstrated the subjective effectiveness of virtual reality psychotherapy through the clinical experiment.

Objectives: Synchronous electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI) has been used to explore sleep stage dependent functional brain networks. Despite a growing number of sleep studies using EEG-fMRI, few studies have conducted network analysis on whole night sleep due to difficulty in data acquisition, artifacts, and sleep management within the MRI scanner. Methods: In order to perform network analysis for whole night sleep, we proposed experimental procedures and data processing techniques for EEG-fMRI. We acquired 6-7 hours of EEG-fMRI data per participant and conducted signal processing to reduce artifacts in both EEG and fMRI. We then generated a functional brain atlas with 68 brain regions using independent component analysis of sleep fMRI data. Using this functional atlas, we constructed sleep level dependent functional brain networks. Results: When we evaluated functional connectivity distribution, sleep showed significantly reduced functional connectivity for the whole brain compared to that during wakefulness. REM sleep showed statistically different connectivity patterns compared to non-REM sleep in sleep-related subcortical brain circuits. Conclusion: This study suggests the feasibility of exploring functional brain networks using sleep EEG-fMRI for whole night sleep via appropriate experimental procedures and signal processing techniques for fMRI and EEG.
