Language Development Disorders*

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.

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.

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.

Along with the development of pediatric emergency technology, more preterm infants with extremely small gestational age and birth weight can survive, yet the long-term follow-up of their neuropsychological development needs to be focused. Language development of preterm infants is an important component of their intellectual development, which reflects the development of their nervous system. Studies about how language develops in preterm infants and what factors are relevant yield inconsistent results. This paper describes the factors influencing the language development of preterm infants, such as gestational age, birth weight and gender. It provides suggestions as to future research and clinical intervention for the language development of preterm infants.
