OBJECTIVE: To compare and analyze the clinical characteristics of children with delayed language acquisition due to two different diagnoses, which were specific language impairment (SLI, a primarily delayed language development) and global developmental delay (GDD, a language delay related to cognitive impairment). METHODS: Among 1,598 children who had visited the developmental delay clinic from March 2005 to February 2011, 467 children who were diagnosed with GDD and 183 children who were diagnosed with SLI were included in this study. All children were questioned about past, family, and developmental history, and their language competences and cognitive function were assessed. Some children got electroencephalography (EEG), in case of need. RESULTS: The presence of the perinatal risk factors showed no difference in two groups. In the children with GDD, they had more delayed acquisition of independent walking and more frequent EEG abnormalities compared with the children with SLI (p<0.01). The positive family history of delayed language development was more prevalent in children with SLI (p<0.01). In areas of language ability, the quotient of receptive language and expressive language did not show any meaningful statistical differences between the two groups. Analyzing in each group, the receptive language quotient was higher than expressive language quotient in both group (p<0.01). In the GDD group, the Bayley Scales of Infant Development II (BSID-II) showed a marked low mental and motor quotient while the Wechsler Intelligence Scale showed low verbal and nonverbal IQ. In the SLI group, the BSID-II and Wechsler Intelligence Scale showed low scores in mental area and verbal IQ but sparing motor area and nonverbal IQ. CONCLUSION: The linguistic profiles of children with language delay could not differentiate between SLI and GDD. The clinicians needed to be aware of these developmental issues, and history taking and clinical evaluation, including cognitive assessment, could be helpful to diagnose adequately and set the treatment plan for each child.

PURPOSE:The purposes of this paper are to analyse the degree of language delay according to the classification and the etiology of mental retardation and to assess the efficacy of language treatment in children who received language treatment. METHODS:The number of the subjects for the research is 79. The subjects had been diagnosed as children of mental retardation after a language development test from the language treatment center of the Chungnam National University Hospital from January, 2003 to December, 2007. We gathered the data concerning their main complaints, their etiology of mental retardation, their results of a language development test and an intelligence test, and their results of language treatment. RESULTS:The results of our analysis to the data are as follows: The distribution of mental retardation classified as mild, moderate, and severe is 51.9% of the subjects, 27.9% and 20.2% each. The etiology of mental retardation is distributed as postnatal(20.3%), prenatal(13.9%), prenatal(5.1%), and idiopathic(60.7%). According to the classification of mental retardation, receptive, expressive, and synthetic language show a significant difference. There is no significant difference in the etiology of mental retardation in statistics. Among 28 children taken a language test after language treatment, 14 mild mental retarded children made their language delay to be shortened by 19.9 months, 10 moderate mental retarded children made their language delay to be shortened by 7.2 months, and 4 severe mental retarded children reduced their language delay by 1.3 month. CONCLUSION:The more severe mental retardation is, the longer language delay occurred. But there is no significant difference to language delay according to the etiology of mental retardation. After language treatment, mild mental retarded children show the remarkable shortening of language delay, while moderate and severe mental retarded children are slightly shortening. Therefore, it is thought that more active language treatment is needed to mild mental retarded children.

OBJECTIVE: To investigate the relationship of language, intelligent and social quotients in children with speech and language disorder and to evaluate the clinical usefulness of language quotient for predicting the extents of cognitive and social functions. METHOD: Total 139 children who visited the department of rehabilitation medicine for the evaluation of suspected speech-language delay. All children were evaluated for receptive and expressive language quotients, articulation accuracy, verbal, performance and full-scale intelligent quotients and social maturation assessment. RESULTS: Approximately 70% of the children who had chief complaints of speech or language disorder were diagnosed as 'receptive and expressive language developmental delay'. Intelligent and social quotients of the children with receptive and expressive language developmental delay were significantly lower than those of the other groups (p<0.05). Both receptive and expressive language quotients, but not dysarticulation, were significantly correlated with intelligent and social quotients (p<0.05). Multiple regression analysis demonstrated that the language quotients could predict intelligent and social quotients as simple equations (p<0.01). CONCLUSION: Primary result of receptive and expressive language quotients from screening test of language evaluation might be able to predict cognitive function and social maturity, which also showed high-degree positive correlation with intelligent and social quotients. This result could provide a useful guideline for further developmental studies in children with speech and language disorder who received primary speech evaluation.

OBJECTIVEAbout 30% of autistic cases experience developmental regression around 2 years of age. The clinical course and manifestations of autistic children with regression remain unclear. This study investigated the clinical features of a group of autistic children with regression.

METHODSOne hundred and fifty-two children at ages of 2.5-6.5 years confirmed with autism based on DSM-IV diagnostic criteria were enrolled. They were grouped according to language development: normal or regression. The perinatal history, developmental history and characteristics of regression were investigated. The symptoms were compared between the two groups.

RESULTSRegressions were observed in 33 children (21.7%) at age of between 16 and 21 months, with loss both in communicative skills and social engagement. The regressive group was scored significantly higher on the Childhood Autism Rating Scale (CARS) (P<0.05) and had a relatively higher proportion of severely ill children (66.7% vs 45.4%; P<0.05)compared with the non-regressive group.

CONCLUSIONSRegression as a characteristic symptom occurs in some autistic children and is of value for diagnosis of autism. The autistic children with regression display more severe social and language impairments than those without regression. Regressive autism may be a special subtype.

PURPOSE: The objective of this study was to test the predictive validity of developmental test for later intellectual development in young children with delayed language development. METHODS: The study subjects were 66 children who had presented delayed language development and had an initial developmental test and a follow-up intelligence test. The mean age at initial test was 34.2 months(17-48 months), and the mean age at the follow-up test was 55.0 months(40-79.5 months). RESULTS: According to CAT DQ(Cognitive Adaptive Test Developmental Quotient), 66 children were divided into 4 groups: group I(CAT DQ<50), group II(50-69), group III(70-84), and group IV(> = or85). There was a moderate correlation between CAT DQ and later total IQ in group I(r=0.58) and II(r= 0.50), but a low correlation in group III(r=0.19) and IV(r=-0.16). IQs in follow-up tests of all children in group I and II were lower than 70, except two children whose IQs were 75 and 78. IQs of children in group III were lower than 85 except for three children whose IQs were 89, 89, and 90, respectively. CONCLUSION: The findings of this study suggest that if DQ is lower than 70, the child is highly probable to be mentally subnormal in later years. Although the correlation between CAT DQ and later total IQ is low in children with DQs over 70, if a DQ is between 70 and 84, the child is very likely to have learning disability in later years.

OBJECTIVETo investigate the influence of home nurture environment on language development and social emotion in children with developmental language disorder (DLD).

METHODSThe 1-3 Years Child Home Nurture Environment Scale, Gesell Developmental Scale, and Infant-Toddler Social and Emotional Assessment Scale were used for the evaluation of 125 children with DLD. A total of 130 children with normal language development matched for age and sex were enrolled as control group.

RESULTSCompared with the control group, the DLD group had a significantly higher proportion of children in a bad home nurture environment and significantly lower scores of all domains of home nurture environment (P<0.05). In children with DLD, the home nurture environment score was positively correlated with the level of language development (r=0.536, P<0.01) and the score of ability domain in social emotion (r=0.397, P<0.01) and was negatively correlated with the scores of the domains of explicit behavior, covert behavior, and imbalance in social emotion (r=-0.455, -0.438, and -0.390 respectively, P<0.01). Home nurture environment had direct influence on language development in children with DLD and affected their language development via the mediating effect of social emotion.

CONCLUSIONSHome nurture environment influences language development and social emotion in children with DLD, and social emotion has a partial mediating effect between home nurture environment and language development.

OBJECTIVE: To evaluate the pattern of developmental delay of language and to correlate the language with other developmental areas in cerebral palsy children. METHOD: Sequenced Inventory of Communication Development (SICD) was studied in 31 children with cerebral palsy of age ranging from 11 months to 48 months. Korean Denver Developmental Screening Test (DDST) was also performed in 18 children simultaneously. RESULTS: On SICD, 10 children (32.3%) showed the receptive language delay and 13 children (41.9%) showed the expressive language delay. Among 15 spastic quadriplegic children, 40% showed the delay of receptive language development, 53.3% showed the delay in expressive language development. Among 10 spastic diplegic children, 30% showed the delay of both receptive and expressive language development. One spastic right hemiplegic child showed a delay of expressive language development, but 4 left hemiplegic children showed the normal language development. One hypotonic cerebral palsy child showed a delay of both receptive and expressive language development. The expressive language was delayed more than the receptive language. SICD correlated highly with the language sector of DDST. And both SICD and DDST language sectors correlated with the other sectors of DDST (personal-social, fine motor-adaptive, gross motor), especially with the fine motor sector (r=0.912, 0.918, 0.976, p<0.001). CONCLUSION: There is a considerably high incidence of developmental delay of language in cerebral palsy children, especially among spastic quadriplegic children. The early evaluation and treatment for the developmental delay of language need to be included in a general rehabilitation program for the cerebral palsy children.

PURPOSE: It is well known that expressive language impairment is commonly less severe than receptive language impairment in children with autism spectrum disorder (ASD). However, this result is based on experiments in Western countries with Western language scales. This study tries to find whether the result above is applicable for toddlers in a non-Western country; more specifically, in Korea with non-Western language scales. MATERIALS AND METHODS: The participants were 166 toddlers aged between 20 months and 50 months who visited the clinic from December 2010 to January 2013. The number of toddlers diagnosed as ASD and developmental language delay (DLD) was 103 and 63, respectively. Language development level was assessed using Sequenced Language Scale for Infants (SELSI), a Korean language scale. Using SELSI, each group was divided into 3 sub-groups. Moreover, the group difference by age was observed by dividing them into three age groups. Chi-square test and linear-by-linear association was used for analysis. RESULTS: Receptive language ability of the DLD group was superior to that of the ASD group in all age groups. However, expressive language ability in both groups showed no difference in all age groups. A greater proportion of expressive dominant type was found in ASD. The 20-29 months group in ASD showed the largest proportion of expressive language dominant type in the three age groups, suggesting that the younger the ASD toddler is, the more severe the receptive language impairment is. CONCLUSION: These findings suggest that receptive-expressive language characteristics in ASD at earlier age could be useful in the early detection of ASD.

OBJECTIVE: To investigate speech development in monosyllables of Chinese 3-year old children, to explore the difficulties of these words in these children, and to provide a reference for rehabilitation of deaf and dumb children. METHOD: Speech material consists of 245 monosyllables in high and flat tone. 71 children between the ages of 2 year and 9 months to 3 year and 3 months (average 3 years) were involved in this investigation by oral imitation test. Proportions correct of every word were statistically analyzed. RESULT: The proportions correct of these words ranged from 0.26 to 1.00 (median= 0.92). There are significant differences among proportions correct of those words (P <0.01). CONCLUSION It should be considered that monosyllables are different in difficulty to Chinese 3 years old children by oral imitation test when selecting materials and criteria of speech test for rehabilitation of deaf and dumb children.
