Sensory dysphasia is a speech disorder. If the symptoms are persistent, it may be caused by a lesion on the left side of the brain, and common diseases include cerebral hemorrhage and cerebral infarction. It usually occurs in middle-aged and elderly people with an acute onset, and most patients may have a history of hyperlipidemia, diabetes and hypertension before the disease. Cerebral hemorrhage usually starts during activity, and cerebral infarction mostly starts in the quiet state. Cranial CT or MRI can make a clear diagnosis, and patients should be hospitalized promptly after the onset of the disease for comprehensive treatment. If the patient’s symptoms are episodic, it may be a transient ischemic attack. The duration of symptoms usually varies from 10-15 minutes and rarely exceeds one hour, and the cranial CT or MRI is normal, which is also mostly seen in middle-aged and elderly people. Most patients may have hyperlipidemia, diabetes and hypertension, etc. If frequent, it may also progress to cerebral infarction, which can be treated with oral aspirin anti-platelet aggregation, and also with drugs to improve blood circulation, etc.
