Cerebral infarction can cause sensory disturbances, motor disturbances, and disorders of consciousness that cause psychiatric symptoms. Some patients have dizziness, ataxia and balance disorders, as well as dysphagia and choking on drinking water. It mainly depends on the location of the infarction and the size of the infarction foci. In the case of infarction of the internal carotid artery system, patients can show sensory and motor disorders of the lateral limbs, and in the case of the left-sided lesion, patients can have speech dysfunction. If the infarction is in the vertebral basilar artery system, it manifests as dizziness, nausea, vomiting, balance disorder and ataxia, and some patients have swallowing difficulties and choking on drinking water. In the case of lobar infarcts, such as frontal and temporal lobe infarcts, patients may experience psychiatric symptoms, and in severe cases, they may also experience disorders of consciousness, such as drowsiness, lethargy, or coma, and increased intracranial pressure. In severe cases, brain herniation can be caused, leading to the patient’s death.
