Today's research has found that the occurrence and development of many asymptomatic cerebrovascular diseases is a very big health risk. Asymptomatic cerebrovascular diseases are mainly divided into three categories: 1. Resting cerebral infarction;2. Magnetic resonance showed vasogenic white matter hyperintensity3. Cerebral microhemorrhage.
OneIs asymptomatic cerebrovascular disease really completely asymptomatic?
Asymptomatic cerebrovascular disease refers primarily to the absence of contralateral hemiplegia, slurred speech, pain, or changes in the sense of touch. However, there are often thinking and emotional disorders, cognitive disorders, and severe cases can cause incontinence. These conditions are also exacerbated when the number of intracranial cerebrovascular lesions increases. Careful neurologic examination reveals signs including asymmetry of tendon reflexes and positive pathologic signs. Therefore, asymptomatic cerebrovascular disease is not truly asymptomatic and requires a careful neurological examination.
IINeuroimaging findings in asymptomatic cerebrovascular disease
The sensitivity of brain MRI (MR) is higher than that of brain CT, resting cerebral infarction and white matter hyperintensity are mainly diagnosed by MR, and cerebral microhemorrhage mainly relies on MR examination. Resting cerebral infarction is mainly lacunar cerebral infarction, with a diameter of 3-15mm. According to statistics, for every 1 symptomatic cerebral infarction detected in clinical practice, there will be 10 resting cerebral infarctions, so the group of asymptomatic cerebrovascular diseases is very considerable.
IIIWhat causes asymptomatic cerebrovascular disease?
Hypertension, hyperlipidemia, and diabetes mellitus are the main risk factors for asymptomatic cerebrovascular disease. High viscosity, high homocysteine, high uric acid, sleep-apnea syndrome, and atrial fibrillation are also risk factors. Patients with poor control of these indicators for a long time should be screened for MR for asymptomatic cerebrovascular disease.
FourthIs asymptomatic cerebrovascular disease needed?
Patients with risk factors such as hypertension, hyperlipidemia, and diabetes mellitus need to control the risk factor indicators to ensure that the indicators meet the standards. Only MR white matter hyperintensity, and routine use of aspirin is not considered.
Intracerebral microhemorrhage should be screened for high-risk or cerebral amyloid angiopathy. If there is cognitive impairment, cases of cognitive**and** with carotid artery stenosis should be performed, and if the stenosis is 75%, it should be evaluated and surgery should be performed if appropriate. ** The focus is on avoiding the progression of asymptomatic cerebrovascular disease to symptomatic cerebrovascular disease.
Asymptomatic cerebrovascular disease is very common, and cranial magnetic resonance imaging should be performed for at-risk groups to facilitate early detection, and effective intervention can prevent symptomatic cerebral infarction and vascular dementia.
