Firstly, the patient may experience aphasia, such as not understanding others' conversations and being unable to accurately express their own opinions. Signs of facial paralysis, such as a skewed mouth, drooling, and nasolabial fold, may also appear. Secondly, limb paralysis is a common clinical symptom, generally presenting as hemiplegia. There may also be hemisensory disturbances, such as numbness on one side of the body. Thirdly, patients may experience a decline in cognitive functions, exhibiting slow reactions, reduced memory capabilities, and decreased computational skills. If a stroke affects the posterior circulation, the patient may experience symptoms such as dizziness, double vision, and hemianopia.

Is lacunar infarction considered a stroke?

Lacunar stroke is a type of stroke, mainly characterized by the blockage of small blood vessels, comprising 21 syndromes. There are motor types, sensory types, mixed types, as well as those combined with speech disorders, swallowing disorders, and unstable walking. If it progresses to become severe or worsens, it can also include dementia and significant cognitive impairment, all of which fall under the category of stroke.

Can a stroke be cured?

Stroke is mainly divided into ischemic stroke and hemorrhagic stroke. Ischemic stroke, also known as cerebral thrombosis, can benefit many patients if they can reach a hospital quickly and receive intravenous thrombolysis within the time window, such as within 4.5 hours, leaving them with only mild neurological deficits followed by proper rehabilitation training. Some patients can be cured. However, if the stroke is severe from the onset, resulting in complete paralysis or even consciousness disorders such as drowsiness, stupor, or coma, the treatment outcomes can be significantly less effective, potentially leaving some degree of disability. Generally speaking, whether a stroke can be cured depends closely on the initial severity of the stroke, the overall condition of the patient, and the timeliness of the treatment. Some conscious patients who receive timely treatment can be cured, whereas those with severe conditions typically suffer from long-term complications.

What medicine is used for stroke?

Stroke primarily refers to cerebrovascular disease, which is divided into two main categories. The first category is hemorrhagic stroke, including cerebral hemorrhage, subarachnoid hemorrhage, and other diseases. The second category is ischemic cerebrovascular diseases, including cerebral thrombosis, cerebral embolism, and other diseases. Thus, although both categories are classified as stroke, the medications used are different. For cerebral hemorrhage, the patient needs to rest in bed and must strictly control blood pressure, primarily using medications that strictly control blood pressure. There are no special oral medications, but intravenous medications can be given to protect brain nerves. If intracranial pressure is high, some dehydrating and intracranial pressure-reducing medications can be administered. For ischemic stroke, such as cerebral thrombosis, it is crucial to get to the hospital quickly. If it is within the thrombolytic time window, intravenous thrombolytic drugs can be administered for treatment, from which many patients may benefit. Additionally, it is necessary to take long-term medications that prevent platelet aggregation and regulate blood lipids, as well as stabilize arterial atherosclerotic plaques.

Precautions for Stroke Patients Using Mannitol

Patients with stroke, if experiencing cerebral hemorrhage, extensive cerebral infarction, or cerebral embolism, can develop cerebral edema. In such cases, it is necessary to use mannitol for dehydration to reduce intracranial pressure. Therefore, it is crucial to strictly determine the appropriate indications. For patients with cerebral hemorrhage, cerebral embolism, or extensive cerebral infarction, the peak period of cerebral edema generally occurs between five to seven days, during which time mannitol should be used to lower intracranial pressure. If the acute phase has passed, then there is no need to use mannitol. For some patients, using mannitol weeks later not only lacks therapeutic effect, it might even worsen the condition. Additionally, when using mannitol, it is important to monitor the patient's renal function. In patients with renal insufficiency, the use of mannitol may exacerbate renal damage, so monitoring changes in renal function is essential. (Please use medication under the guidance of a doctor.)

Is a stroke a cerebral infarction?

Stroke includes cerebral infarction. Stroke is divided into ischemic stroke and hemorrhagic stroke. Therefore, ischemic stroke is cerebral infarction, and hemorrhagic stroke is cerebral hemorrhage. Thus, one cannot say it is solely a cerebral infarction; it includes cerebral infarction. If symptoms of stroke appear, such as unclear speech or limb weakness, it might be either hemorrhagic or ischemic stroke. In such cases, it is crucial to seek medical attention immediately. For hemorrhagic stroke, one should visit the neurosurgery department, and for ischemic stroke, the neurology department is appropriate. Initially, a CT scan should be performed to make a clear diagnosis.
