Whether the right cerebral infarction can return to self-care depends on the severity of the patient’s neurological deficit. In patients with right cerebral lacunar infarction and cerebral infarction with NIHSS score below 3, the neurological impairment caused is not serious, and patients can have no obvious clinical symptoms or only mild slurred speech and left-sided limb weakness, and patients can completely take care of themselves. However, if the patient has a large right-sided cerebral infarction, or a severe brainstem, cerebellar or internal capsule infarction with a high NIHSS score, the resulting neurological deficits are more severe, and the patient mostly remains with obvious symptoms such as impaired consciousness, hemiparesis, vertigo, nausea, vomiting and incontinence, the treatment effect is not ideal, and although after standardized treatment and rehabilitation training, the patient will still have obvious sequelae. These patients mostly need full or partial assistance from others, and it is difficult for them to fully resume self-care.
