There are some most common signs for cerebral embolism, of course, if we want to understand the signs of cerebral embolism carefully, we also need to consider the onset of the patient, besides we need to understand the care of the disease, we also need to understand the degree of cooperation of the patient, then we need the best psychological care for patients with cerebral embolism. 1, middle cerebral artery embolism: the most common, its clinical manifestations cause hemiplegia, hemianesthesia and hemianopsia on the opposite side of the lesion when the main trunk embolism. Embolism of the main trunk of the dominant hemisphere artery can have aphasia, loss of writing and reading. If the infarct area is large, the severe condition may cause increased intracranial pressure, coma, brain herniation, or even death; embolization of the deep branch of the middle cerebral artery or the doublestem artery may cause hemiparesis contralateral to the lesion, generally without sensory impairment or isotropic hemianopia, and damage to the dominant hemisphere, which may have aphasia. Embolism of various cortical branches of the middle cerebral artery can cause contralateral hemiparesis of the lesion, with the face and upper limbs being the most important. The dominant hemisphere can cause motor aphasia, sensory aphasia, loss of reading, loss of writing, and loss of use; the nondominant hemisphere can cause contralateral hemianopia and other somatic disorders. Focal epilepsy can occur in a few patients. 2.The embolization of the anterior cerebral artery may produce sensory and motor disorders of the lower limbs contralateral to the lesion, central facial palsy, lingual palsy and upper limb paralysis, and mental disorders such as emotional indifference, euphoria and strong grip reflex, which may be accompanied by urinary retention. 3. Embolism of the posterior cerebral artery may cause ipsilateral hemianopsia or superior quadrant blindness, hemianesthesia with thalamic pain on the contralateral side of the lesion. It may also cause chorea-like tachycardia of the limb contralateral to the lesion and various ocular muscle paralysis. 4. The most common symptoms of basilar artery embolism are vertigo, nystagmus, diplopia, crossed paresis or crossed sensory disorder, and limb ataxia. If the main trunk of basilar artery is embolized, tetraplegia, ocular muscle paralysis, pupil narrowing, often accompanied by facial nerve, spreading nerve, trigeminal nerve, vagus nerve and hypoglossal nerve paralysis and cerebellar symptoms, etc. In severe cases, coma, tetraplegia, central hyperthermia, gastrointestinal bleeding and even death can occur rapidly. Although the above experts have given a summary of the signs and symptoms of cerebral embolism, we also need to consider the onset of the patient in time, and the family members of the patient also need to cooperate with the treatment of the disease, because for the patients with cerebral embolism, only with timely treatment will the pain of the patient be reduced and the effect of the disease treatment will appear.
