The severity of bilateral lateral paraventricular cavernous cerebral infarction is generally less severe than bilateral non-cavernous cerebral infarction, but it also needs to be judged according to the specific clinical situation, and the situation of some patients may be more serious. Generally speaking, bilateral paraventricular cavernous infarction is less severe than bilateral non-cavernous infarction, with better therapeutic effect and better prognosis, which is not life-threatening, but also belongs to the urgent and serious diseases in neurology, which need timely treatment. The severity of bilateral paraventricular cavernous cerebral infarction is also related to the number of infarcts, comorbidities, and age of the patient. In general, the higher the number of infarcts, the more comorbidities such as hypertension, diabetes mellitus, obesity, and heart disease, and the more severe the intracranial atherosclerosis, the worse the treatment and prognosis. Although bilateral paraventricular cavernous cerebral infarction is generally not life-threatening, without timely treatment and rehabilitation, it can easily lead to large-scale cerebral infarction, resulting in cognitive impairment, permanent sequelae, and even life-threatening. Therefore, once detected, it is necessary to actively go to the hospital and cooperate with doctors for treatment to prevent the condition from worsening.
