Cavernous brain infarcts are relatively small focal brain infarcts that are almost impossible to eliminate once they form. No matter what time of year you go back to review the cranial CT or MRI, you can almost always see the softening foci. Cerebral infarction refers to ischemic disease causing nerve cell necrosis, nerve cell necrosis is almost no regenerative ability, will be left with soft foci, in the imaging performance of the lesion can always exist, does not mean that it is not able to functionally return to normal, most of the cavernous cerebral infarction can be recovered. Most of the lacunar infarcts can be recovered. Lacunar infarcts are relatively small cerebral infarcts, with fewer nerve cells damaged, and the symptoms are relatively limited or mild, and they can be functionally restored to normal through rehabilitation training, with the help of the surviving nerve cells in the surrounding area instead of compensating for the function of the damaged nerve cells, and only a few infarcts affecting the important functional areas may have more or less residual after-effects. After the recovery of lacunar cerebral infarction, attention should still be paid to the prevention of the risk of recurrence, cerebral infarction occurs most of the risk factors of cerebrovascular disease, such as hypertension, diabetes mellitus, hyperlipidemia, and there is still a risk of recurrence in the future if the risk factors are not controlled.
