It is recommended to actively address a cold in cases of cerebral infarction, as most people with cerebral infarction who also have motor disabilities are predominantly bedridden, making them prone to aspiration pneumonia. If a cold is not managed well and develops into pneumonia, it can further aggravate the condition, potentially worsening the perceived motor disabilities if timely functional rehabilitation is not administered, leading to further progression of the illness.

Symptoms of cerebral infarction

Patients with cerebral infarction may exhibit paralysis of one side of the body and aphasia. If the patient has a brainstem infarction, symptoms may include unclear speech, difficulty swallowing, and coughing while eating. In cases of cerebellar infarction, there may not be symptoms of hemiplegia; the main symptom is usually dizziness. Additionally, large-scale cerebral infarctions can lead to disturbances in consciousness, manifesting as coma. Typically, cerebral infarctions do not affect consciousness unless they are extensive, which may also lead to coma. Moreover, patients with cerebral infarction often experience symptoms while resting quietly, commonly waking up in the morning to find themselves unable to speak or with paralysis on one side of the body, although their consciousness remains clear. These are typical manifestations of cerebral infarction.

Is lacunar infarction a serious illness?

Lacunar stroke is a condition where small blood vessels in the cerebral hemispheres or brainstem undergo pathological changes and eventually become occluded as a result of common risk factors such as prolonged hypertension or diabetes. This leads to the necrosis of brain tissue. Typically, the infarct size is less than 1.5 to 2 centimeters, resulting in clinical syndromes associated with impaired neurological functions governed by the affected area. Often, lacunar strokes may be asymptomatic in some patients, while others may experience mild symptoms. Generally, the prognosis of this disease is good.

Cerebral infarction X-ray manifestations

Brain infarction generally does not involve X-rays because X-rays primarily target bone issues, not brain tissue issues. If a brain infarction occurs, a cranial CT or MRI can be performed. In acute cases of sudden onset, a cranial CT is primarily used to exclude cerebral hemorrhage, as brain infarction typically does not show up in the acute phase. However, in cases of extensive brain infarction, changes might also appear on a CT during the acute phase. Additionally, after the acute phase, about 1 day or 24 hours later, brain infarctions generally appear as low-density shadows on a CT. On an MRI, in diffusion imaging, brain infarctions generally appear as high-density, high-signal areas, while they appear as low-signal areas in T1 imaging and high-signal areas in T2 imaging. It is also suggested to perform cranial magnetic resonance angiography to examine the status of the blood vessels.

CT manifestations of cerebral infarction

Brain infarction has different manifestations on CT scans at different stages. Generally, within 24 hours, the CT scan may not show any imaging of the cerebral infarction lesion. However, some patients, especially those with thrombosis in the middle cerebral artery, might exhibit a high density sign in the middle cerebral artery. In cases of large-scale cerebral infarction, some sulci on the side affected by the infarction may appear shallower, indicating possible brain swelling. Generally, within 24 hours, a CT scan can reveal a low-density image, which appears relatively darker. This condition is typically considered a brain infarction, and as time progresses, this dark, or low-density image, tends to become even darker. In some patients during the acute phase, although the infarction may not be apparent, a CT scan is performed to rule out bleeding, as CT is very sensitive to bleeding.

How long does one need to be hospitalized for a cerebral infarction?

The duration of hospitalization for cerebral infarction varies from person to person, depending on the different conditions of the stroke patients, the different causes of the stroke, and the different treatment goals. Generally, the hospitalization time is seven to fourteen days. If the condition of the cerebral infarction is relatively mild, it is also possible to be discharged in five to seven days. However, for some patients with severe conditions, even those who are in a coma or have complications, the hospitalization time will be longer.
