Abstract PDF: BACKGROUND
The causes of ADHD(attention deficit hyperactivity disorder) are various, it is impossible to understand the whole characteristics of ADHD, only with simple intellignece testing scales. We compared cognitive characteristics of ADHD group with normal controls with Korean Kaufman Assessment Battery for Children(K-ABC), It is well known to evaluate neuropsychological and cognitive aspects of the children. MATERIALS AND METHODS: Age and sex matched 40 ADHD patients and 40 normal controls tested with the K-ABC. Each subscales compared between pre-treatment patients and controls, pre-treatment and post-treatment in patient group, post-treatment patients and controls. RESULTS: Significant differences are ovserved in sequential processing, simultaneous processing, cognitive processing and achievement between pre-treatment patients and controls, and in gestalt closure between pre-treatment and post-treatment patients group. But there are no significant differences between pre-treatment patients and controls in gestalt closure and reading/decoding. CONCLUSIONS: Methylphenidate improved the scores of simultaneous scale, which means improvement of executive functions such as divided attention, analysis and organization. Methylphenidate also reduced distractibility.

Abstract PDF: BACKGROUND
Models of attention deficit hyperactivity disorder(ADHD) that have proposed a hypodopaminergic state resulting in hypofunction of the prefrontal circuitry have assumed a unitary dopamine system, which largely ignores the distinct functional differences between mesocortical dopamine system and nigrostriatal dopamine system. PURPOSE: The author's goal was to develop a pathophysiological model for ADHD with greater explanotory power than dopaminergic hypofunction hypothesis in prefronal circuitry. MATERIALS AND METHODS: Published clinical findings on ADHD were integrated with data from genetic, pharmacological, neuroimaging studies in human and animals. RESULTS: Molecular genetic studies suggest that three genes may increase the susceptibility to ADHD. The three candidate genes associated with ADHD are each involved in dopaminergic function, and this consistent with the neurobiologic studies implicating catecholamines in the etiology of ADHD. Pharmacological data also provide compelling support for dopamine and noradrenergic hypothesis of ADHD. Neuroimaging studies lend substantial support for the hypothesis that right-sided abnormalities of prefrontal-basal ganglia circuit would be found in ADHD. CONCLUSIONS: The present hypothesis takes advantage of the major differences between the two pertinent dopamine systems. Mesocortical dopamine system, which largely lacks inhibitory autoreceptors, is ideally positioned to regulate cortical inputs, thus improving the signal-to-noise ratio for biologically valued signals. In this circuit, therapeutic doses of stimulants are hypothesized to increase postsynaptic dopamine effects and enhance executive functions. By contrast, symptoms of hyperactivity/impulsivity in ADHD are hypothesized to be associated with relative overactivity of nigrostriatal circuit. This nigrostriatal circuit is tightly regulated by inhibitory autoreceptoors as well as by long distance feedback from the cortex, and slow diffusion of therapeutic doses of stimulant via oral administration is hypothesized to produce a net inhibition of dopaminergic neurotransmission and improves hyperactivity.

Abstract PDF: The purpose of this study was to examine the reliability and validity of attention deficit disorder evaluation scale-school version(ADDES-SV). Between October 1996 and November 1996, ADDES-SV was administered to 263 elementary school students in the second grade and between Jun 1996 and October 1996, 28 attention deficit hyperactivity disorder patients. In the reliability test, the test-retest reliability coefficient was significantly high and that of inattention was 0.88, that of impulsivity was 0.80, that of hyperactivity was 0.83 and total score was 0.83. In the reliability test by internal consistancy, the Cronbach alpha coefficient was significantly high and that of inattention was 0.98, that of impulsivity was 0.87, that of hyperactivity was 0.87(p<0.05). The half-sprit reliability coefficient by first-second half method showed high correlation and that of inattention was part 1: 0.96, part 2: 0.96 impulsivity was part 1: 0.95, part 2: 0.93, hyperactivity was part 1: 0.92, part 2: 0.94(p<0.05). Inter-rater reliability by pearson correlation coefficient was significantly high and that of inattention was 0.92, that of impulsivity was 0.87, that of hyperactivity was 0.89 and total score was 0.89. The concurrent validity between ADDES-SV and CAP scale was 0.85 in attention deficit hyperactivity disorder patient group and 0.79 in normal control group(p<0.05). In discriminant validity test between attention deficit hyperactivity disorder patient group and normal control group, the patient group showed higher score(p<0.05). The total discriminant capacity of the patient group in ADDES-SV was 94.6%. In this point of view, ADDES-SV scale showed high reliability and validity in applying to Korean subjects and was proved to be the useful screening test tool for attention deficit hyperactivity disorder research.

Abstract PDF: The purpose of this study was to examine the reliability and validity of a Korean form of Childhood Attention Problem(CAP) scale. CAP were administered to 98 normal elementary school students as control group and 98 attention deficit hyperactivity disorder patients. Male students showed high scores than female students in both subscale and total scores, but not statistically significant. There were no significant difference in CAP scale between male students and female students in attention deficit hyperactivity disorder patients. In the reliability test, the test-retest reliability coefficient was highly satisfactory and that of inattention subscale was 0.83, impulsivity subscale was 0.70 and total score was 0.82. In the reliability test by internal consistency, the Cronbach a coefficient was highly satisfactory and that of inattention subscale was 0.91, overactivity subscale was 0.89(p<0.05). The concurrent validity between CAP scale and ADDES-HV scale was 0.85 in attention deficit hyperactivity disorder patient group and 0.73 in normal control group(p<0.05). In discriminant validity test between attention deficit hyperactivity disorder patient group and normal control group, the patient group showed higher score(p<0.05). The total discriminant capacity of the patient group in CAP was 93.4%. In this point of view, CAP scale showed high reliability and validity in applying to Korean subjects and was proved to be the good and simple screening test tool for attention deficit hyperactivity disorder research and can help many young patient to treat early.

Abstract PDF: The objectives of this study were to evaluate the effect of methylphenidate on attention deficit hyperactivity disorder (ADHD) and the comorbidity of the disorder, using child attention problem checklist to .56 (male : 38, female : 18) patients from. March 992 to February 1993. The results were as follows: Among 56 subjects, ADHD alone were 20 (335.71%) subjects, and with one additional diagnosis were 31 (55.35%) subjects and with two additional diagnosis were 5 (8.93%) subjects. There was significant improvement on symptoms in the scores rated by teachers in 7th and 28th day after mentylphenidate administration compared to baseline score (P<0.05) and 28th day score showed significant improvement compared to. 7th day score (P<0.05) and 28th day score showed significant improvement compared to 7th day score (P<0.05). There was significant improvment on symptoms in the scores rated by parents in 28th day after methylphenidate administration improvement compared with 7th day score. In single administration of methylphenidate in Sunday morning score compared to afternoon score (P<0.05). In the administration of significant improvement on symptoms compared with the Sunday morning rating score of parents (P<0.05) and the 28th day comparison was also showed significant improvement on symptoms in the scores rated by teachers compared with the scores rated by parents on symptoms (P<0.05). Among group comparison, all groups showed significant improvements (P<0.05) except conduct disorder & oppositional defiant group.

Abstract PDF: To evaluate the simplicity and efficacy of the 7-symptom screen test for somatization disorder, the authors tried 7-symptom screen test to find out the easiness in diagnosing the somatization disorder and to evaluate the simplicity and efficacy of it from Mar 1991 to Feb 1992. The objects were 135 female outpatients who visited Department of Psychiatry, College of Medicine, Yeungnam University. The results were as follows; The discriminant index was over 3.0 for all 7 symptoms and two item accuracy was 89% (sensitivity 99%, specificity 77%), three item accuracy was 87% (sensitivity 83%, specificity 90%). In discriminant analysis, the cut off score for the criteria of somatization disorder was 87% when three or more symptoms were checked for 7-symptoms. This result means that 7-symptom screen test is the simple and accurate method for screening and diagnosing the somatization disorder.

Abstract PDF: The authors studied anxiety-depression using New Anxiety-Depression Scale (NADS) in the subjects of 2,564 male and 1,252 female college freshmen of Yeungnam University. The authors collected the reports of NADS during the periods from January to February 1987, and applied ANOVA and t-test on anxiety depression scores in order to compare them between various psychosocial factors and sexes. The results are as follows: There was significant difference in the mean average of total scores between male and female students: male students scored 33.41±8.76 and female students scored 35.34±9.02 (P<0.001). The anxiety-depression scores relating to the items of sleep disturbance, apprehension, facial flushing and fatigue were relatively scored higher in both groups. One hundred and thirty nine male students (5.4%) showed seriously higher degree of anxiety-depression scores of 50 or more, while eighty eight female students (7.0%) showed the same scores. There was a strong tendency toward higher anxiety-depression scores in the students who were dissatisfied with their home atmosphere, colleges, departments, familiarity of parents and those who had pessimistic views of self image in the past, presents and future in both groups (P<0.001).

Abstract PDF: The authors studied anxiety-depression using New Anxiety-Depression Scale (NADS), in the subjects of 3,499male and 1,335 female college freshmen of Yeungnam University. The authors collected the reports of NADS during the periods from January to February, 1986, and applied ANOVA and t-test on anxiety-depression scores in order to compare them between various psychosocial factors, and sexes. The results are as follows: There was significant difference in the mean averages of total scores between male and female students: male students scored 31.49±6.57 female students scored 33.37±6.84 (p<0.001) The anxiety-depression scores relating to the items of sleep disturbance, apprehension, decreased libido, and fatigue were relatively higher in both groups. Ninety-nine male students (2.8%) showed seriously high degree anxiety-depression scores of 50 or higher, while forty female students (3.0%) showed the same scores. There was a strong tendency toward higher anxiety-depression scores in the students who were dissatisfied with their home atmosphere, colleges, departments and familiarity of parents, and those who had pessimistic views of self image in the past, present, or future in both groups (p<0.001). The students whose maturation locations were below city level, showed higher level of anxiety-depression scores in both groups (p<0.05). NADS and SAS, SDS, and Leeds scale were correlated significantly in 0.64, 0.61, and 0.77 of correlation coefficient.

Abstract PDF: The authors studied anxiety, using Zung's Self-Rating Anxiety Scale (SAS), in the subjects of 3,499 male and 1,335 female college freshmen of Yeungnam University. The authors collected the reports of SAS during the periods from January to February, 1986, and applied ANOVA and t-test on anxiety scores in order to compare them between various psychosocial factors, and sexes. The results are as follows: There was significant difference in the mean averages of total anxiety scores between male and female students: male students scored 32.91±7.70, female students scored 34.48±6.00, (P<0.001). The anxiety scores relating to the items of sweating, apprehension, restlessness, and insomnia were relatively higher in both groups. The anxiety scores relating to the items of faintness, mental disintegration, tremors, dizziness were lower in both groups. Thirty-nine male students (1.1%) showed seriously high anxiety scores of 50 or higher, while twenty-one female students (1.6%) showed the same scores. So the authors inferred that the features of anxiety symptoms were much the same in our country, but female showed more various symptoms and higher level of anxiety than males. Male students attending in pharmacy showed higher level of anxiety scores (P<0.01). There was a strong tendency toward higher anxiety scores in the students who were dissatisfied with their home atmosphere, colleges, department and familiarity of parents, and those who had pessimistic views of self image in the past, present, or future, in both groups (P<0.001).

Abstract PDF: The authors studied depression, using Zung's self-rating Depression Scale (SDS), in the subjects of 65 males and 231 females at the homes for the aged in Taegu and Kyong-buk areas. The authors collected the date of SDS during the period from June to August, 1986, and applied ANOVA and t-test on the depression scores in order to compare them between various psychosocial factors and sexes. The results could be summarized as follow: There was significantly difference in the mean average of total depression scores between the two groups: elderly males scored 38.80±11.92, elderly females scored 43.21±14.33 (p<0.05). The depression scores in the items of hopelessness, personal devaluation, weight loss, emptiness and confusion were relatively higher than the scores in the other items in both groups. Nine elderly males (16%) showed seriously high depression scores of 50 and over, while fourth-seven elderly females (33%) showed the same scores. Among these psychosocial factors, age, birth place, and growing place are significantly related to higher depression scores in both groups.

Abstract PDF: Separation anxiety disorder (SAD) is characterized by excessive anxiety about being apart from the individuals to whom a child is most attached. We noticed a case of a 13 year old boy's SAD with symptoms of nausea/vomiting, stomachache, school refusal, and severe weight loss. His mother was overanxious and overdependent but her dependency was frustrated due to family problem. We investigated this case from a point of developmental aspect and family dynamics and tried to attempt therapeutic approach.
