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.

The difference between stroke and cerebral infarction

Stroke is divided into hemorrhagic stroke and ischemic stroke. Hemorrhagic stroke involves cerebral hemorrhage, while ischemic stroke involves cerebral infarction. Therefore, the difference is that stroke includes cerebral infarction, which is a type of ischemic stroke. In such cases, it is crucial to seek prompt hospital treatment and examine for risk factors related to cerebrovascular disease. Under the guidance of a doctor, the condition should be stabilized since the acute phase of a cerebral infarction might be unstable and could worsen. Thus, after stabilizing the condition, long-term oral medication will also be necessary to prevent future strokes.

Stroke Rehabilitation Treatment Plan

In the rehabilitation treatment of stroke patients, we first need to conduct a comprehensive rehabilitation assessment, evaluating the patient's current primary clinical symptoms, nutritional status, and rehabilitation functional impairments. Based on the results of the assessment, we determine the patient's main functional impairments, targeting a series of functional impairments such as mobility, hand function, as well as speech and swallowing disorders. We adopt a series of therapeutic interventions including exercise therapy, occupational therapy, physical therapy, swallowing therapy, speech therapy, psychological therapy, rehabilitation engineering, and rehabilitation nursing. Generally speaking, through evaluation, we develop a personalized rehabilitation treatment plan for the patient, comprehensively promoting the patient's overall recovery, improving the patient’s ability to live independently, and helping them return to their families, society, and work positions as soon as possible.

What are the symptoms of a stroke?

Symptoms of stroke vary greatly, and it is crucial to judge based on the circumstances. The symptoms are mainly divided into two major categories: hemorrhagic stroke and ischemic stroke. The most common symptoms of hemorrhagic stroke are severe headaches, projectile vomiting, and the gradual onset of consciousness disorders. Some people might also experience limb numbness, weakness, speech impediments, and other conditions. The most common symptoms of ischemic stroke include dizziness, limb numbness, and speech impediments; sometimes, these symptoms alternate, so it is essential to pay attention to clinical observations and focus on differential diagnosis. There are also other types of symptoms, such as cognitive decline, urinary and fecal incontinence, unstable gait, swallowing difficulties, and coughing while swallowing. Therefore, it is imperative to visit a hospital in a timely manner for testing to clearly understand the specific changes in the patient's condition at that time, thus better facilitating the patient’s recovery.

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.

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.)
