Muteness

life science Maturity 11-13 Next article →

Muteness is when a person does not use speech. This can happen for many different reasons. Some people can still hear others talking. Others may not be able to hear at all.

Some causes are physical. A person might have an injury to the mouth or tongue. They might have a problem with the larynx. This is the part of the body that makes the voice. Other people have apraxia. This is when the muscles used for speech do not work well together. Damage to the brain can also cause muteness. This might happen after a stroke or brain surgery.

Other causes are not physical. Some children have selective mutism. This means they only talk in certain places. They might talk to family but stay quiet at school. This often happens before a child is five years old. It can be linked to anxiety or stress.

Doctors use tests to find the cause. This helps them pick the right help. Some people use tools to talk. They might use speech-generating devices. These are tools that make sounds for them. Others use pictures on velcro strips to show what they need. These tools help everyone share their ideas.
