What's the cause for stammering? Is it a disease? Can it be cured?

There are many reasons like lack of confidence, inferiority complex, lack of finding right sentences but it's curable with practice and consultation.

Stammering may be a physical condition that could be cured by speech therapy or other medical treatment. This could also be because of lack of confidence.

Stammering I think is due to lack of confidence I have seen most of the people who stammer they do it when they are nervous which can be cured but its all depends on the person.

Many people don't have presence of mind. They don't understand what to speak. Hence they start stammering. Sometimes the get confused and nervous. Stammering can also be due to disease. This is curable if treatment is done on time.

Though I am not aware of what causes stammering, however, it is condition which can be corrected with proper language and speech therapy. Also, the person who stammers needs to be supported by his or her family to overcome fear of speaking and to boost confidence to overcome this condition.

It is a psychological problem which can be set right by some counselling and medication.It normally develops in those who have had some trauma and also are shy and lack self confidence ...

It is disease. It has many form. We can correct it by therapy.

Yes it is a disease and this can be cured through counselling.
