Dyslexia is an impairment in the 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.
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

The only known risk factor is having a family member with dyslexia.

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 abilityIQ test—measure of intellectual functioningTests to measure speaking, reading, spelling, and writing skills
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 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 timeTeach the same concepts many times—a concept known as over-teachingUse all the senses—hearing, vision, voice, and touch—to enhance learning (multisensory reinforcement)
Compensatory strategies are ways to work-around the effects of dyslexia. They include: Audio taping classroom lessons, homework assignments, and textsUsing flashcardsSitting in the front of the classroomUsing a computer with spelling and grammar checksReceiving more time to complete homework or tests
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.
