What if the patient can understand but can t speak, and can only gesture?

Aphasia refers to the lesions of brain tissue related to language function, such as stroke, traumatic brain injury, brain tumor, brain inflammation, etc., resulting in impairment of the patient's ability to understand and express the human communicative symbol system, especially the comprehension and expression of speech, vocabulary, grammar and other components, language structure and the content and meaning of language, as well as the decline of language cognitive processes and functional impairment as the basis of language. Aphasia does not include language symptoms due to impaired consciousness and general mental retardation, nor does it include language, reading, and writing disorders caused by damage to sensory and motor organs such as hearing, vision, writing, and pronunciation.

It refers to the lesions of brain tissue related to language function, such as stroke, traumatic brain injury, brain tumor, brain inflammation, etc., which cause damage to the patient's ability to understand and express the human communicative symbol system, especially the comprehension and expression of speech, vocabulary, grammar and other components, language structure and language content and meaning, as well as the decline of language cognitive process and functional impairment as the basis of language. This impairment manifests itself in varying degrees of dysfunction in listening, speaking, reading, and writing. Since aphasia is a disorder in the comprehension and expression of symbolic speech, it also includes other systemic disorders related to the symbolic system, such as the ability to perform using gestures.

Moreover, patients with aphasia will also experience changes in intelligence, such as changes in memory, logical thinking, calculation, and attention.

Aphasia does not include language symptoms due to impaired consciousness and general mental retardation, nor does it include language, reading, and writing disorders caused by damage to sensory and motor organs such as hearing, vision, writing, and pronunciation. Language deficits caused by congenital or juvenile illness that cause learning difficulties are also not classified as aphasia.

In general, the prognosis of aphasia is consistent with the prognosis of the primary disease, and with the acceleration of the aging in China, aphasia tends to be severe and complicated. Coupled with the low brain function due to age, symptoms may worsen. Aphasia can also worsen if there is another stroke or if the disease is progressive.

The prognosis for aphasia is related to the following: The sooner language training begins, the better. The younger the patient, the better.

Degree of aphasia: mild is better. Primary symptoms:

The prognosis of the first stroke is good, and the prognosis of traumatic brain injury is better than that of stroke. Comorbidities: Those without comorbidities are better than those with comorbidities.

Broca's aphasia, transcortical motor aphasia, virulent aphasia, and named aphasia have a better prognosis than other types of aphasia.

Speech function is innervated by one cerebral hemisphere, called the dominant hemisphere. With the exception of a few, the dominant hemisphere of the vast majority is located in the left cerebral cortex and its connecting fibers. Aphasia often occurs with damage to the dominant hemisphere.

Different types of aphasia can occur when different parts of the dominant hemisphere are damaged: the posterior part of the third frontal gyrus is the center of speech, and when damaged, the ability to express orally is lost, i.e., motor aphasia; The posterior part of the first transverse temporal gyrus is the auditory center, and when it is damaged, it is incomprehensible to the language of others, i.e., sensory aphasia; The posterior part of the third frontal gyrus is the writing center, which cannot be expressed by writing when the lesion is diseased, which is agraphia; The angular gyrus is the reading center, and when it is damaged, it is impossible to read the pronunciation of the text and does not know its meaning, which is dyslexia; The area between the first temporal gyrus and the angular gyrus is the naming center of the object, and the name of the person seen cannot be said at the time of the lesion, which is named aphasia. Cerebrovascular diseases are the most common diseases that cause aphasia, followed by brain inflammation, trauma, and degeneration.
