Cavernous brain infarcts are usually without signs.
Cavernous cerebral infarction refers to the occlusion of the lumen of a small penetrating artery deep in the cerebral hemisphere or brainstem, forming a small infarction foci. Due to the small foci, patients with lacunar cerebral infarction may have no obvious clinical symptoms, and those who have symptoms may show mild hemiparesis, dysarthria, ataxia and so on, but there are no signs and symptoms.
The main cause of lacunar cerebral infarction is atherosclerosis, which mostly occurs in middle-aged and old-aged people, especially those who suffer from long-term hypertension, hyperlipidemia and diabetes mellitus. Since some of them have no obvious clinical symptoms, they are usually detected by CT or MRI examination of the skull.
Cavernous cerebral infarction is not harmful to the body, but it is easy to recur, so those who suffer from cavernous cerebral infarction should consult a doctor in time and actively intervene and treat it.
