What is Specific Learning Disorder (SLD)?
Specific Learning Disorder is a neurodevelopmental difference characterized by an individual's inability to perform as expected in reading, writing, and/or mathematics, despite having a mental capacity appropriate for their age and education level.
These difficulties persist even when appropriate instruction and support are provided, significantly impacting the individual's academic life.
Why Does It Occur?
There is no single cause for Specific Learning Disorder. Research suggests that the following factors may play a role:
- Genetic predisposition (Family history)
- Structural differences related to brain development and function
- Processing difficulties in language and cognitive processes
Types of Specific Learning Disorders
Three primary areas fall under the SLD umbrella:
1. Dyslexia (Reading Disorder)
- Difficulty learning the relationship between letters and sounds
- Slow and error-prone reading
- Difficulty with reading comprehension and phonological processing issues
2. Dysgraphia (Writing Disorder)
- Illegible handwriting and skipping or reversing letters
- Frequent errors in spelling and grammar rules
- Organization problems in written expression
3. Dyscalculia (Mathematics Disorder)
- Difficulty understanding number concepts and symbols
- Confusion with the sequence of mathematical operations
- Errors in multi-step calculations and difficulty in problem-solving
Preschool Risk Indicators
While diagnosis is usually made in primary school, the following "early warning" signs should be noted:
- Delays in receptive and expressive language or speech sound disorders
- Weak phonological awareness (difficulty with rhyming, segmenting sounds, etc.)
- Difficulties in rapid naming and working memory issues
- Challenges with attention and executive functions
The Role of the Speech and Language Therapist (SLT)
Dyslexia and dysgraphia are essentially language-based learning disorders. The SLT manages the following processes:
- Detailed evaluation of oral and written language skills
- Analysis of the relationship between language and literacy
- Development of phonological awareness, letter-sound knowledge, and grammatical structures
- Identifying risk groups in the preschool period and ensuring collaboration between family and teachers
Evidence-Based Intervention Approach
Approaches proven scientifically effective are systematic, gradual, and multisensory.
Important Warning:There is no strong scientific evidence that colored lenses, special fonts, or eye exercises improve academic skills.
The Importance of Early Intervention: Early support increases academic success, strengthens self-confidence, and reduces secondary emotional problems.
