(Specific Reading Disability)
Definition
Definition
Dyslexia is a disability that can hinder a person’s ability to read, write, and spell. It is a common learning disability in children and lasts throughout life. The severity of dyslexia can vary from mild to severe.
Causes
Causes
The causes of dyslexia are neurobiological (having to do with the way the brain is formed and how it functions) and genetic (passed down through families). Dyslexia may also occur in people later in life due to other conditions, such as stroke.

Risk Factors
Risk Factors
The only known risk factor is having a family member with dyslexia.
Symptoms
Symptoms
Symptoms may include difficulty in the following areas:
- Learning to speak
- Reading and writing at grade level
- Organizing written and spoken language
- Learning letters and their sounds
- Learning number facts
- Spelling
- Learning a foreign language
- Correctly doing math problems
Diagnosis
Diagnosis
You will be asked about you or your child’s symptoms and medical history. A physical exam will be done. It will include a hearing and vision test. You may then be referred to an expert in learning disabilities, such as a school psychologist, learning specialist, or neurologist (doctor who specializes in the nervous system) for additional testing.
Additional tests may be done. These may include:
- Cognitive processing tests—measure of thinking ability
- IQ test—measure of intellectual functioning
- Tests to measure speaking, reading, spelling, and writing skills
Treatment
Treatment
Most people with dyslexia need help from a teacher, tutor, or other trained professional. Talk with the doctor and learning specialist about the best treatment plan for you or your child. Treatment options include:
Remediation
Remediation is a way of teaching that helps people with dyslexia to learn language skills. It uses the following concepts:
- Teach small amounts of information at a time
- Teach the same concepts many times—a concept known as over-teaching
- Use all the senses—hearing, vision, voice, and touch—to enhance learning (multisensory reinforcement)
Compensatory Strategies
Compensatory strategies are ways to work-around the effects of dyslexia. They include:
- Audio taping classroom lessons, homework assignments, and texts
- Using flashcards
- Sitting in the front of the classroom
- Using a computer with spelling and grammar checks
- Receiving more time to complete homework or tests
Prevention
Prevention
There is little that can be done to prevent dyslexia, especially if it runs in your family. However, early identification and treatment can reduce its effects. The sooner children with dyslexia get special education services, the fewer problems they will have learning to read and write at grade level. Under US federal law, free testing and special education services are available for children in the public school system.
