ABSTRACT
Objective:To explore the early-stage language characteristics of children with autism spectrum disorder (ASD), global developmental delay (GDD), and developmental language disorder (DLD) at the same deve-lopmental level, thus providing references for their diagnosis.Methods:Clinical data of 719 children, involving 382 ASD patients, 198 DLD patients and 139 GDD patients presented to the Children′s Hospital Affiliated to Chongqing Medical University from January 2018 to January 2020 were retrospectively analyzed. Chi- square test was used to compare the developmental distribution of 3 groups.Variance analysis was used to analyze difference of developmental levels among 3 groups.Correlation analysis was used to analyse relationship between language and nonverbal abilities.At the same developmental, student′s t test was used to compare ASD with GDD, ASD with DLD in language ability, and difference of expression with receptive and visual related language. Results:The nonverbal developmental levels of ASD, GDD, DLD children were significantly different ( χ2=414.64, P<0.01). Language abilities were correlated with non-verbal developmental levels( r=0.60, P<0.05). The receptive and visual-related language abilities of ASD children with abnormal developmental level were more delayed compared with that of expressive language ( t=6.97, 3.58, 13.29, 6.85, 9.09, 7.27, all P<0.01). Expressive language of DLD children with normal developmental level was worse than visual-related and receptive language( t=-2.21, -3.61, all P<0.05). In GDD children with mild delayed development, receptive language was worse than expressive and visual-related language ( t=4.12, -4.24, all P<0.01), GDD children with moderate and worse development had worse visual-related and receptive language than the expression ( t=2.46, 2.68, all P<0.01). No significant differences in the expressive, receptive and visual-related language were detected in ASD and DLD children with normal development level and those with delayed development level (all P>0.05). Receptive and visual related language of ASD children with marginal delayed development level were significantly worse than those of DLD children ( t=-4.64, -4.60, all P<0.01), whereas no significant diffe-rence in the expression was detected ( P>0.05). In ASD children with mild delayed developmental level, the receptive and visual-related language were worse than those of GDD children( t=-4.11, -4.68, all P<0.01), whereas no significant difference in the expression was detected ( P>0.05). Conclusions:In early childhood, ASD children with abnormal developmental levels present severe delay in receptive and visual related language.DLD children with normal development have an obvious delay in expressive language.The language abilities of GDD children are globally delayed, especially the receptive language.In the marginal and mild delayed developmental level, ASD is featured by obvious delay of receptive and visual-related language.In normal and worse delayed development levels, the development of language in ASD, DLD and GDD children is similar.
ABSTRACT
The humanity-oriented spirit is being reestablished and developed in medical activities,but there are still deviations clearly demonstrated in language expression and communications between doctors and patients.This paper discusses the relationship between medicine and language expression,empirically analyzes the language problems in physician-patient communication including inadequacy of information,rigidness of speech,frankness in speech,the lack of language skills,shortage of non-linguistic information,and the causes of such problems.Finally,the paper proposes that language cultivation should be improved and restressed from the perspectives of both medicine and linguistics.
