Cerebral infarction (Stroke)


The difference between lacunar infarction and cerebral infarction
Lacunar stroke is a type of cerebral infarction and is considered the mildest form within strokes. Generally, the area affected by a lacunar infarction is very small, so if it is a single incident or there are not many lacunar strokes, it usually does not cause any symptoms. Many middle-aged and elderly people over the age of fifty or sixty who undergo routine CT scans during physical examinations exhibit signs of lacunar stroke on their CT images, yet most of them do not present any clinical symptoms. Therefore, lacunar stroke may only affect brain function and result in symptoms such as speech difficulties, slow reactions, weakened muscle strength in the limbs, or lack of coordination when there are numerous occurrences. Cerebral infarction can include strokes that affect larger areas of the brain, which are much more severe than lacunar strokes. These larger strokes are sufficient to cause clinical symptoms, which may include hemiplegia, drooping of the corner of the mouth and drooling, abnormal limb movements, and even fatal events in cases of extensive cerebral infarction. Thus, lacunar stroke, being a type of cerebral infarction, represents the mildest form of stroke.


Can someone who has had a cerebral infarction eat eggs?
Patients with cerebral infarction can eat eggs. In clinical practice, many people believe that eggs, especially egg yolks, contain very high cholesterol, which can easily lead to hyperlipidemia. However, this does not specifically cause hyperlipidemia. Eating one egg a day generally does not have a severe impact on the human body. After all, the human body is constantly active and consumes nutrients. Eating an egg will not particularly affect the body but will supplement many proteins and other essential substances. Therefore, it is best to eat eggs. However, if there are other symptoms present, such as difficulty swallowing, coughing while eating, or a comatose state, then eggs should not be consumed. It is crucial to make judgments based on the situation.


Is a grade II cerebral infarction serious?
A second-degree cerebral infarction is a very serious matter that must be given significant attention clinically. Once a cerebral infarction occurs, it indicates very poor vascular quality. If proactive treatment and prevention are not undertaken to prevent further progression, the symptoms of cerebral infarction can worsen and recur frequently. This can cause severe harm not only to the patient but also to their family and society. This is particularly true for patients with severe, long-term bedridden hemiplegia, which further increases the burden on families and society. Therefore, once a cerebral infarction occurs, regardless of the circumstances, it is crucial to complete the necessary examinations and take timely treatment measures to better manage the progression of the condition.


How to treat cerebral infarction?
The choice of treatment for cerebral infarction depends on the specific circumstances. Treatment plans for small and large cerebral infarctions are completely different, as are the treatment plans for acute and chronic stages of cerebral infarction. For small areas of acute cerebral infarction, many cases can be treated with intravenous thrombolysis and arterial thrombectomy, which are currently very effective treatments that can significantly help in emergency situations. In the chronic phase, it is necessary to actively improve cerebral circulation, brain protection, lower lipids, stabilize blood sugar, and blood pressure, among other methods, to delay the further progression of the disease. Some cases may also require identifying the cause and opting for surgical interventions, including stent implantation and endarterectomy surgeries.


Can people with cerebral infarction drink alcohol?
Patients with cerebral infarction should not drink alcohol. Although alcohol can have certain effects in promoting blood circulation and removing blood stasis, the specific content of alcohol and its degree, as well as each person's tolerance, vary. While in some cases, certain components can promote blood circulation, this does not mean it always activates blood circulation. In fact, excessive promotion of blood circulation at times can even lead to cerebral hemorrhage and other changes in medical conditions, posing even greater risks to patients. Another point is that drinking alcohol can cause excitement, which may lead to increased blood pressure. If there are plaques or other impurities in the arteries, they might dislodge and lead to further exacerbation of cerebral infarction. Therefore, it is also advised not to drink alcohol for these reasons.


Symptoms of stroke worsened in the elderly
Elderly people who experience a cerebral infarction (stroke) may show several typical symptoms if the condition worsens. Firstly, their speech may suddenly become unclear, accompanied by a slight drooping of the mouth and drooling. Another symptom is difficulty in extending the tongue straight out, as it may not align centrally. Additionally, there may be weakness in the limbs. These symptoms indicate the presence of a new cerebral infarction lesion. In such cases, it is crucial to promptly go to the hospital for a head CT scan or an MRI to determine whether the scope of the stroke has expanded or if a new stroke has occurred.


Symptoms of cerebral infarction
For patients with cerebral infarction, during the acute phase, they typically exhibit clear symptoms of headache, dizziness, nausea, and vomiting. Patients may experience slurred speech, difficulty speaking, and obvious articulation disorders. Additionally, some patients may develop facial nerve paralysis, deviation of the mouth to one side, drooling, and often exhibit clinical signs such as a shallower nasolabial fold and disappearance of forehead wrinkles. Furthermore, some patients may also experience dysphagia, manifested by coughing when drinking water, and may be accompanied by aphasia or motor dysfunction, primarily presenting as motor aphasia, mixed aphasia, anomic aphasia, and resulting unilateral limb paralysis.


Causes of cerebral infarction
There are many causes of cerebral infarction, but the most common in clinical practice is the narrowing or occlusion of the carotid artery. Since the brain is supplied by four blood vessels, any issues with any of these vessels can potentially lead to a cerebral infarction. Conditions commonly known as the "three highs"—high blood pressure, high blood sugar, and high cholesterol—can easily lead to narrowing or even blockage of the blood vessels. Thus, these factors are fundamentally the cause. Additionally, smoking and drinking can also lead to vascular narrowing and cause cerebral infarction. In some special cases, autoimmune diseases can cause inflammation inside the vessels, leading to narrowing. Other causes include arterial tears due to trauma, which can lead to ischemia and infarction, or abnormal blood supply due to arrhythmias causing cerebral infarction.


Brain infarction belongs to which department?
Brain infarction is usually classified as a neurology disease. Patients with brain infarction often exhibit clear symptoms of headache, dizziness, nausea, vomiting, and significant swallowing dysfunction, leading to coughing while drinking. Some patients may also experience facial nerve paralysis to some extent, manifesting as unclear speech, difficulty speaking, and articulation disorders. When the aforementioned clinical symptoms occur, the possibility of brain infarction is considered high. Performing a cranial MRI scan for patients can help determine the specific location, number, and severity of the infarction. Generally, it is recommended to treat patients with brain infarction during the acute phase with drugs that enhance brain function, nourish the nerves, and promote blood circulation to remove blood stasis, and many patients can achieve satisfactory treatment results. (Specific medications should be used under the guidance of a physician.)


Methods of Cerebral Infarction
There are many methods for treating cerebral infarction, but it is essential to make judgments based on the situation, as each patient's condition is different and requires different treatment approaches. For patients with acute cerebral infarction, treatments such as emergency thrombolysis or thrombectomy can be undertaken. For chronic cerebral infarction, initially, medical treatment is applied, including managing blood pressure, lowering blood lipids, stabilizing blood sugar levels, quitting smoking and alcohol, etc. Subsequently, this includes the oral administration of antiplatelet aggregation medications, which can effectively reduce the recurrence of cerebral infarction. Finally, corresponding surgical treatments are considered, including endarterectomy, superficial temporal artery to middle cerebral artery anastomosis, and appropriate stent implantation surgeries, depending on the specific characteristics. (Specific medications should be administered under the guidance of a physician.)
