Cerebral thrombosis aphasia is caused by the occlusion of an artery in the brain, causing damage to the speech center and resulting in aphasia. After 3-4 weeks of onset, some patients with milder symptoms may recover on their own. Within 3 months of onset, aphasia may gradually improve as brain cells and cerebral edema subside. Within 3-6 months of onset, the degree of symptom improvement proceeds at a decreasing rate, with symptoms improving more slowly. After 6 months of onset, the improvement of symptoms is minimal, and the recovery period is within 1 year, and beyond 1 year is the post-onset period. According to the fluency of the patient’s spontaneous speech, it is divided into fluent and non-fluent aphasia, and generally fluent aphasia recovers better than non-fluent aphasia. Regardless of the type of aphasia, early intervention in rehabilitation treatment can greatly improve the patient’s ability to communicate in speech.
