OBJECTIVES: The attentional deficit is a core symptom in attention deficit hyperactivity disorder. The major brain areas related to attention are frontal and parietal lobes. Abnormalities of frontal and parietal lobes in attention deficit hyperactivity disorder have been reported in previous researches. But, most of the researches are based on comparing patients and controls while they are in resting condition. Further research on funtional changes related to performance of attentional task is needed to understand the attentional dysfuntion in attention deficit hyperactivity disorder. In this study, the localized functional changes of the brains related to attentional task in patients with attention deficit hyperactivity disorder and the differences of them between patients and normal controls were examined. Also the effect of the methylphenidate on functional changes related to attentional task in patients with attention deficit hyperactivity disorder was examined. METHOD: Quantitative electroencephalography (QEEG) was applied to examine the fuctional changes related to attentional task. Subjects of this study consisted of 20 patients with attention deficit hyperactivity disorder and 20 controls who were matched age, sex, handedness, intelligence. QEEG was recorded on eye open resting condition, and on performing computerized attentional task. In cases of patients, after taking of methylphenidate, QEEG was recorded on both conditions. RESULTS: 1)In attention test, normal controls had better scores in response time and variabilities of response time than those of patients with attention deficit hyperactivity disorder without taking methylphenidate. After taking medication, scores of omission, response time and variabilities of response time were significantly improved, comparing to scores without taking medication. No differences were recognized between the controls and patients with taking medication in scores of attention test. 2)In resting condition, spectral EEG revealed baseline activity levels of patients were significantly increased comparing to those of controls. 3)Analysis of delta wave revealed that amplitudes of controls were significantly elevated in parieto-occipital area during performance of attentional task. But in patients, localized activated area related to attentional task was not remarkable. 4)Theta activity of controls were significantly elevated in right frontal, right temporal, and both parieto-occipital areas during performance of attentional task. But in patients without taking medication, localized activated area related to attentional work was not remarkable. After taking medication, right frontal, right temporal, and both parieto-occipital areas were significantly activated. 5)Alpha activities of controls were significantly increased in parieto-occipital area during performance of attentional task, but those of patients without taking medication were increased in broad area. 6)Beta activities of controls were significantly increased in frontal area during attentional performance, but those of patients without taking medication were significantly increased in most of the brain areas. After taking medication, significantly increased activities related to attentional task were recognized in left frontal, and both temporal areas. Localized activated patterns similar to those of controls were recognized. CONCLUSION: Based on the results of this research, it is suggested that patients with attention deficit hyperactivity disorder have increased baseline brain activity. In controls, brains showed localized response to a attentional stimuli, and functional changes related to attentional stimuli were recognized in frontal, and parieto-occipital areas. But, patients failed in showing appropriate localized activated response to attentional stimuli. It is concluded that frontal and parieto-occipital areas have some deficit responsible for the attentional dysfunction of attention deficit hyperactivity disorder.

OBJECTIVE: Dopamine transporter is a key regulator of dopamine neurotransmission and is also the primary target of methylphenidate. This study tested the hypothesis that dopamine transporter (DAT) density in basal ganglia is a predictor of favorable methylphenidate (MP) treatment response. METHODS: 15 drug-naive boys with ADHD were included in this study (8 children: treatment responder, 7 children: treatment non responder). They were assessed with psychiatric interview, KEDI-WISC, K-ARS, ADS and CBCL. After then, they were performed [123 I]IPT SPECT. They were evaluated about treatment response after treatment with methylphenidate during 8 weeks. SPECT data reconstructed for the assessment of specific/nonspecific DAT binding ratio of the basal ganglia were compared between treatment responders and nonresponders. RESULTS: There were not significant differences in dopamine transporter density in basal ganglia between the two groups. CONCLUSION: This finding suggests that dopamine transporter density does not mediate the MP treatment response in a direct way.

OBJECTIVES: Tourette's Disorder (TD) is a chronic neuropsychiatric disorder characterized by multiple motor and vocal tics with onset in childhood. The aim of this study was to ascertain the increased cortical information transmission in frontal area during tic suppression in drug naive boys with TD using new nonlinear analysis of EEGs, be called Transfer Entropy (TE) which can detect the directed exchange of information between two systems. METHODS: Subjects were 11 drug naive boys with DSM-IV diagnosis of TD and 10 control boys. Clinical assessments were performed, and EEGs were recorded from 19 scalp loci of the international 10-20 systems. TE was estimated by EEG timeseries data after noise reduction. TE difference between TD and control during resting state and between tic suppression and resting state in TD were investigated. RESULTS: Elevated TE was found in extensive channels, including frontal, central and temporal channels (F7, Fz, F8,Cz, C3, P3, T3, and T4) in resting state of Tourette's disorder compared to normal controls. During tic suppression elevated TE was found in more extensive and asymmetrical channels especially prefrontal area (Fp1, Fp2, F3, Fz, F7, F8, Cz, C4, C5, T3, and T4). CONCLUSION: These findings suggest that pathogenesis of Tourette's disorder involve impaired cortical neuronal modulation in subcortical neural circuits. EEG analysis of TE may be a useful tool to investigation of cortical mechanism of psychiatric illness.

BACKGROUND: Nowadays, although its clinical value remains controversial institutions utilize hair mineral analysis. Arguments about the reliability of hair mineral analysis persist, and there have been evaluations of commercial laboratories performing hair mineral analysis. OBJECTIVE: The objective of this study was to assess the reliability of intra-laboratory and inter-laboratory data at three commercial laboratories conducting hair mineral analysis, compared to serum mineral analysis. METHODS: Two divided hair samples taken from near the scalp were submitted for analysis at the same time, to all laboratories, from one healthy volunteer. Each laboratory sent a report consisting of quantitative results and their interpretation of health implications. Differences among intra-laboratory and interlaboratory data were analyzed using SPSS version 12.0 (SPSS Inc., USA). RESULTS: All the laboratories used identical methods for quantitative analysis, and they generated consistent numerical results according to Friedman analysis of variance. However, the normal reference ranges of each laboratory varied. As such, each laboratory interpreted the patient's health differently. On intra-laboratory data, Wilcoxon analysis suggested they generated relatively coherent data, but laboratory B could not in one element, so its reliability was doubtful. In comparison with the blood test, laboratory C generated identical results, but not laboratory A and B. CONCLUSION: Hair mineral analysis has its limitations, considering the reliability of inter and intra laboratory analysis comparing with blood analysis. As such, clinicians should be cautious when applying hair mineral analysis as an ancillary tool. Each laboratory included in this study requires continuous refinement from now on for inducing standardized normal reference levels.

OBJECTIVES: Craving is the subjectively experienced motivational states inducing ongoing drug use in addicts. It also proceeds or precipitates relapse episode in drug addicts. Alcohol craving may be triggered by exposure to an object, environment, or emotion that a person has come to associate with alcohol consumption. Such stimuli are called alcohol-related cues. Among alcohol-related cues, alcohol-related visual stimuli are simple and reliable methods in inducing alcohol craving. The object of this study is to develop alcohol-related visual stimuli which induce alcohol craving reliably and to investigate the characteristics of alcohol-related visual stimuli in alcoholics. METHODS: First, the authors developed 27 alcohol and drinking color photos as candidate stimuli. Then, 3 photos which induce alcohol craving most were chosen as alcohol-related visual stimuli respectively by alcoholics, alcoholism high risk group and normal control group. The authors compared characteristics, situation and complexity of selected alcohol-related visual stimuli among three groups. RESULTS: 1) 'A glass of Soju', 'Drinking together' and 'A glass of beer, a bottle of beer and a sidedish' were chosen as alcohol-related visual stimuli which induce most craving in alcoholics, alcoholism high risk group and normal control group respectively. 2) Alcohol photo(stationary object) induced craving most in alcoholics in contrast with drinking photo(situation) in social drinkers. Alcoholics clung to alcohol per se, not to atmosphere or situation of drinking, and alcoholism high risk group felt craving by the expectation of drinking situation. Normal control group showed no consistent finding in choosing alcohol-related visual stimuli. CONCLUSION: With these results, the author suggests classical conditioning as psychopathological model of alcohol craving with alcoholics. In contrast with alcoholics, alcohol craving of alcoholism high risk group may be related to alcohol specific memory or positive expectancies about alcohol use. These finding may support different neurobiological mechanisms of alcohol craving between alcoholics and social drinkers.
