What is Specific Language Impairment (SLI)?;\u00a0<\/span><\/h2>\n

\u0397 <\/span>Specific Language Disorder<\/b> (Specific Language Impairment (SLI) is described in the DSM-5 (American Psychiatric Association Classification) as \u201cLanguage Disorder\u201d and in the ICD-10 (World Health Classification) as \u201cSpecific Developmental Language Impairment\u201d (F80).\u00a0<\/span><\/p>\n

It is further identified as F80.1 (expressive type), F80.2 (perceptive type) and F80.9 (unspecified type).<\/span><\/p>\n

It is a speech development disorder that affects only the ability to express or understand language,<\/span> not associated with mental retardation, autism, neurological impairment or sensory deficits<\/b>.<\/span><\/p>\n

Differentiation from other disorders:<\/span><\/h3>\n

SLI is radically different from autism, mental retardation and dyslexia.\u00a0<\/span><\/p>\n

At <\/span>autism<\/span>, apart from communication difficulties, there are deficits in social interaction, limited interests and stereotypes. In SLI, however, the difficulties are limited exclusively to speech (expression, comprehension) and are not accompanied by socialisation difficulties, stereotypes or limited behavioural patterns.\u00a0<\/span><\/p>\n

\u0397 <\/span>dyslexia<\/span> refers to difficulties in decoding written language (reading, spelling), while SLI is found in oral language (expression, comprehension). In SLD, the child may have difficulty understanding spoken language or forming correct sentences, but may not have difficulty decoding text.<\/span><\/p>\n

\u0397 <\/span>mental retardation<\/span> is characterised by low performance at the overall cognitive level (low IQ), difficulties in problem solving, understanding abstract concepts and self-identification.\u00a0<\/span><\/p>\n

In contrast, children with SLI have normal intelligence, understand the world around them, but have difficulty using language correctly.<\/b><\/p>\n

According to <\/span>surveys<\/span><\/a> (Bishop, 2014), children with SLI demonstrate normal intelligence and social development, understanding emotions and social rules.\u00a0<\/span><\/p>\n

In short, SLI is exclusively related to language development, while the other conditions involve broader difficulties.<\/span><\/p>\n

Categorization:<\/span><\/h3>\n

Expressive type (F80.1):\u00a0<\/b><\/h4>\n

In this type of disorder, children have difficulty using language to express their thoughts correctly. Although they understand what they hear, they find it difficult to form correct syntactic structures, use appropriate verb tenses or choose the right words. Their speech may be short, telegraphic or contain syntactic and morphological errors<\/span>.
\n<\/span><\/p>\n

It is important to note that SLI language difficulties differ from SLI language difficulties. joint difficulties<\/a>, where the main problem concerns the purity of the production of speech sounds rather than the grammar and structure of the language.
\n<\/span><\/p>\n

Perceptual type (F80.2):<\/b><\/h4>\n

Here the difficulty lies in the children's ability to understand spoken language. They may find it difficult to understand complex commands, to relate words correctly to their meaning or to understand the tone and style of other people's speech.\u00a0<\/span><\/p>\n

This often leads to interaction difficulties, despite the fact that it is not associated with cognitive impairment or autistic spectrum.<\/span><\/p>\n

Mixed form (F80.9):<\/b><\/h4>\n

This type combines features of both the expressive and perceptual type. Children find it difficult to understand the speech of others and to express their thoughts correctly.\u00a0<\/span><\/p>\n

These are usually more complex cases, which require a multi-level assessment and treatment approach.<\/span><\/p>\n
