The prognosis for mutism is good. Sometimes it disappears suddenly on its own.

i have selective mutism myself and there is really no cause for it other then you have it in your genetics

The diagnosis of mutism is fairly easy to make because the signs amd symptoms are clear-cut and easily observable.

Selective mutism is when someone talks in some situations, such as at home or with their best friends, but can't talk in others, like at school, due to anxiety.

You can get more information on wikipedia's selective mutism article and at selective mutism.com.

Hope this helps!
