In clinical practice, the recovery rate of cerebral hemorrhage aphasia is only about 5%-7%, which is relatively small. This is because once aphasia is formed after a brain hemorrhage, it is difficult to recover later. Language is a relatively complex process that does not only require language function, such as the absence of abnormalities in the anatomical structure of the pharynx, but more importantly, it requires the ability of the human mind to organize the language and control the relevant details. Therefore, once the language center is destroyed, many patients are often unable to speak although they have the ability to do so, so overall, the recovery rate of aphasia is relatively poor.
