Hemiparesis due to cerebral infarction is a type of limb motor dysfunction caused by cerebral infarction. It is mainly seen in patients with large hemispheric infarction and basal ganglia infarction. Patients with large hemispheric infarction can have contralateral limb hemiparesis, hemianopia, and hemianesthesia, and patients with left-sided lesions can have speech dysfunction. Severe patients may have consciousness disorders, which can cause cerebral edema, increased intracranial pressure, and even brain herniation, leading to death; patients with basal ganglia infarction may have hemiparesis, hemianopia, and hemianesthesia, and generally no consciousness disorders. Its treatment mainly consists of drug therapy while patients should undergo early rehabilitation after their condition is stabilized, with the aim of reducing signs and symptoms of neurological deficits and preventing sequelae.
