Codes
Description
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 disabilities
- 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% of children have noticeable speech disorders. Speech and language therapy can help.

About this page. This page brings together public information from official sources, each cited where it is used. It is not medical advice, it is not a diagnosis, and it does not tell you which treatment to take.
Treatments. Indications are quoted unchanged from official product information (European Medicines Agency, U.S. Food and Drug Administration). They describe what a medicine is approved for, not whether it is right for you. Approved uses can differ between countries. Always read the package leaflet and follow your doctor's or pharmacist's advice.
What people report. Figures marked "reported by Anpheros users" are anonymous counts from at least 20 people who agreed to share them. They show what people report, not what works, and they are not clinical evidence.
Links between terms. "May be associated with" means the link appears in a cited source. It does not mean you have that condition.
In an emergency, call 112 (or your local emergency number). Do not delay seeking medical help because of something you read here.
