Aphasia
Causes of Aphasia
Aphasia usually results from disorders that do not cause progressive damage, such as the following: A Ischemic Stroke None A Cerebral Contusions and Lacerations None A brain infection ( Encephalitis ) In such cases, aphasia does not continue to worsen over time. But if it results from a progressive disorder (such as an enlarging brain tumor), aphasia can progressively worsen. As the tumor gets bigger, it may put more pressure on areas of the brain that control language function and further impair the ability to express or understand language. Some types of dementia can also cause aphasia that progressively worsens. People with aphasia have difficulty expressing or understanding language. But the nature and degree of the difficulty vary. The variety reflects the complex nature of language function.
