How is speech affected?
Speech is affected in two ways. In some patients it is slurred and indistinct or even completely absent, but the patient can read, write, and understand perfectly what is said. This condition is called dysarthria, and it usually yields to treatment. The other condition is much more complex. It is called dysphasia or aphasia and is due to damage to the part of the brain which controls all language processes. This can affect the patient’s ability to speak, understand speech, read and write.
