Language-Based Learning Disabilities
Language-based learning disabilities are problems with age-appropriate reading, spelling, and/or writing. This disorder is not about how smart a person is. Most people diagnosed with learning disabilities have average to superior intelligence.
Preschool Language Disorders
Preschool children (3 to 5 years old) with language disorders may have trouble understanding and talking.
A child with selective mutism does not speak in certain situations, like at school, but speaks at other times, like at home or with friends. Selective mutism often starts before a child is 5 years old and is usually first noticed when the child starts school.
