Information for Patients

Speech and Communication Disorders

Also called: Communication disorders

Many disorders can affect our ability to speak and communicate. They range from saying sounds incorrectly to being completely unable to speak or understand speech. Causes include

  • Hearing disorders and deafness
  • Voice problems, such as dysphonia or those caused by cleft lip or palate
  • Speech problems like stuttering
  • Developmental disabilities
  • Learning disorders
  • Autism spectrum disorder
  • Brain injury
  • Stroke

Some speech and communication problems may be genetic. Often, no one knows the causes. By first grade, about 5 percent of children have noticeable speech disorders. Speech and language therapy can help.
