Symptoms

Dyslexia is characterized by difficulties in decoding and recognizing written words accurately. People with dyslexia may encounter challenges connecting sounds to letters (phonological processing) or recognizing words by sight (visual processing).

1. Early signs in children

  • Difficulty learning to read
  • Slow reading and writing
  • Difficulty spelling
  • Challenges with phonological awareness (difficulty recognizing and manipulating the sounds of spoken language)
  • Memory challenges

2. Signs in adults

  • Difficulty organizing thoughts
  • Struggles with time management
  • Reading aloud issues
  • Avoidance of reading

Cause

Dyslexia often runs in families. A child’s reading ability is influenced by home literacy and the quality of teaching.

Studies have shown that reading difficulties are highly heritable, with certain genes affecting brain development and reading skills.

Research indicates that individuals with dyslexia have structural and functional differences in their brain related to language processing.

These brain differences are distinct from those found in conditions like autism and ADHD, highlighting the unique pathways leading to dyslexia.

The exact causes of dyslexia are not fully understood; however, certain risk factors can contribute to dyslexia, which are discussed below in the next segment.

RiskFactors

Here are some common risk factors associated with dyslexia:

  • Genetic factors:
    • Dyslexia tends to run in families, suggesting a genetic component.
    • Certain genes related to language and reading skills may play a role.
  • Prenatal and Perinatal Factors:
    • Maternal smoking
    • Alcohol
    • Drug use during pregnancy
    • Low birth weight
    • Premature birth
  • Environmental factors:
    • Limited access to books and reading materials
    • Reduced opportunities for language stimulation
  • Family history of reading difficulties:

    Individuals with a family history of reading difficulties or other learning disabilities may have a higher risk of developing dyslexia.

  • Early language difficulties:

    Children who experience delays in early language development, including difficulties with phonological awareness (the ability to recognize and manipulate the sounds of language), may be at a higher risk for dyslexia.

Diagnosis

Diagnosing dyslexia involves a comprehensive assessment. The key steps in the diagnosis include:

I. Screening for Risks

  • Screenings often involve assessing basic reading skills and phonological awareness.
  • Screening tools may include standardized tests, teacher observations, and informal assessments.

II. Comprehensive Evaluation

A comprehensive evaluation is typically recommended if screening results suggest a potential issue. This in-depth process delves into various facets of reading, spelling, writing, and language skills.

III. Testing Components

The comprehensive evaluation includes a range of tests:

  1. Questionnaires: The service provider might ask your child, their carers, or their teachers to complete surveys. Tests to measure reading and language skills may be given to your child.
  2. Neurological, Vision, and Hearing Tests: These can assist in determining whether another disorder is contributing to or causing your child's reading difficulties.
  3. Psychological Assessment: This can help identify whether your child's abilities may be hindered by social issues, anxiety, or depression.
  4. Tests for Academic Skills:
    • Decoding: Assessing the ability to read unfamiliar words by sounding them out.
    • Oral Language Skills: Evaluating spoken language abilities, including vocabulary, grammar, and expressive/receptive language skills.
    • Reading Fluency and Comprehension: Testing the speed and understanding of reading passages.
    • Spelling: Assessing spelling proficiency.
    • Vocabulary: Evaluating understanding and use of words.
    • Word Recognition: Examining the ability to recognize and identify words.

Note: Dyslexia is not diagnosed through standardized tests or medical exams, but through classroom observations and multiple assessments.

Prevention

Dyslexia cannot be prevented because it is often linked to genetic factors. However, early intervention, supportive learning environments, and targeted educational strategies can help manage its effects and improve reading and learning outcomes for individuals with dyslexia.

Treatment

Treatment for dyslexia typically involves a combination of educational, therapeutic, and supportive approaches. Here are key components of how dyslexia can be treated:

  • Multisensory Structured Language Education (MSLE)
    This approach involves using multiple senses (sight, sound, touch, and movement) to help individuals with dyslexia learn and internalize language skills.
  • Phonics Instruction
    Teaching phonics, the relationship between sounds and letters, is crucial for individuals with dyslexia. Explicit and systematic phonics instruction helps improve decoding skills.
  • Individualized Education Plans (IEPs)
    In an educational setting, students with dyslexia may benefit from individualized plans that outline specific accommodations and modifications to support their learning needs. These plans may include extra time on exams, access to audiobooks, and other adjustments.
  • Speech-Language Therapy
    If language-related difficulties are present, speech-language therapy can be used to address oral language skills and communication.
  • Occupational Therapy (OT)
    Occupational therapy may be beneficial if hand movements or sensory processing issues impact writing and related tasks.

Along with these therapies, individuals with dyslexia need additional kindness, understanding, and nurturing.
