The term "DNT" refers to the time from when an acute stroke patient arrives at the hospital to the start of intravenous thrombolytic treatment. Both domestic and international guidelines recommend the DNT to be within 60 minutes—the earlier, the better. This standard was established by the National Health and Family Planning Commission. The time it takes for pre-hospital emergency care and in-hospital medication administration is approximately 60 minutes each. It is only by improving the time from pre-hospital treatment to medication administration within this golden window that we can enhance the patient's survival rate, prognosis, and quality of life, while minimizing disability rates.

Does lacunar infarction belong to ischemic stroke?

Lacunar infarction is a type of ischemic stroke, which can be simply explained as the blockage of small blood vessels. It generally belongs to one of the categories of ischemic strokes, which also include large vessel blockage and cerebral embolism. Lacunar infarction specifically refers to blockages in small blood vessels, and this type of stroke primarily occurs due to these small vessel blockages, and it is known as lacunar infarction.

Main manifestations of pre-stroke warning signs

The precursor of cerebral thrombosis in neurology is called transient ischemic attack (TIA). As the name suggests, this is a transient disease, mainly characterized by symptomatic speech impairment, facial droop, drooling, episodic dizziness, blurred vision, and episodic numbness and weakness of limbs. These symptoms are generally transient, usually lasting from several minutes to a few hours and can be completely relieved. The precursor of cerebral thrombosis is regarded as an emergency in neurology and must be treated promptly. Delayed treatment can possibly progress to cerebral infarction, severely affecting the patient's quality of life and physical health. In considering this disease, one must immediately rush to the hospital for appropriate treatment with antiplatelet drugs, lipid-regulating drugs to stabilize plaques, and treatments such as volume expansion and fluid supplementation.

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.

What is a stroke?

The English term for 脑卒中 is stroke, which generally refers to a group of cerebrovascular diseases. These diseases often onset acutely and mainly consist of two types. The first type is ischemic stroke, which includes diseases like cerebral thrombosis, watershed infarction, cerebral infarction, and cerebral embolism. The second type is hemorrhagic stroke, which primarily includes cerebral hemorrhage and subarachnoid hemorrhage among other bleeding-related disorders. Regardless of the type, the onset of stroke is very sudden, and patients rapidly develop severe neurological deficits. For example, a patient may experience sudden slurred speech, paralysis of one side of the body, or numbness and weakness on one side. There will inevitably be obvious symptoms like dizziness, headache, nausea, vomiting, and stiffness of the neck. If a stroke is suspected, it is crucial to rush to the hospital immediately. Doctors will make an accurate diagnosis and provide appropriate treatment based on the patient's medical history and cranial CT scans.

Principles of Stroke Rehabilitation Treatment

Principles of stroke rehabilitation treatment. First is the issue of timing; it is crucial to choose the appropriate time for rehabilitation intervention. Rehabilitation treatment should start as early as possible when the patient's condition is stable. Secondly, rehabilitation assessment, also known as rehabilitation evaluation, should be performed throughout the treatment process. This allows for comparability before and after treatment, clarifying the treatment results for the patient and determining if there is a need to modify the treatment plan during the process. Thirdly, it is essential to have rehabilitation treatment goals and plans. Based on assessments, short-term and long-term rehabilitation plans must be developed for the patient to achieve certain rehabilitation objectives. Fourth, the principle of gradual progression must be adhered to in rehabilitation treatment. It should not be rushed, and active participation from both the patient and their family members is crucial, incorporating daily life and exercise opportunities. Fifth, rehabilitation treatment primarily involves comprehensive therapy, which includes physical exercise, speech therapy, occupational therapy, physiotherapy, and traditional rehabilitation treatments such as acupuncture and moxibustion, as well as psychological therapy, rehabilitation engineering, and assistive devices. Sixth, conventional pharmacological treatments and necessary surgical interventions are involved. These include essential medications that must be used, and when rehabilitation methods alone cannot restore function, appropriate medical advice from relevant departments should be considered, and surgical treatment may be needed to assist the patient in better recovery.
