Stroke
Post-stroke depression
Recent studies have confirmed that in addition to language dysfunction, cognitive impairment, and motor dysfunction, stroke patients also exhibit many signs of depression. According to guidelines published in China in 2016, about 33% of stroke patients experience post-stroke depression, which is a very high proportion. The main symptoms of post-stroke depression include a lack of interest in anything, unwillingness to communicate with others, being quiet and reticent, non-compliance with medication, and non-cooperation with rehabilitation training. Post-stroke depression significantly affects the recovery of patients and their future quality of life. Some patients may even turn to suicide due to depression. Therefore, it is crucial to pay attention to depression after a stroke, as the incidence rate of post-stroke depression is very high, reaching up to 33%. Clinicians must carefully identify it, and family members of patients must be attentive in their care.
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.
Causes of Dysphagia after Stroke
The causes of dysphagia resulting from a stroke are largely related to the location of the stroke. Dysphagia mainly involves the glossopharyngeal and vagus nerves, which are distributed in the medulla oblongata of the brainstem. Therefore, if you have a brainstem stroke, specifically at the medulla oblongata, there is a significant chance of experiencing coughing due to aspiration and dysphagia. If the stroke occurs in a different area, these symptoms are unlikely to appear. A stroke in the cerebral hemisphere, since it has bilateral nerve supply, does not lead to noticeable coughing if only one side is affected. However, if one side is affected this year and the other side next year, similar symptoms of aspiration cough and dysphagia will occur. Therefore, neurologically, the location and specific site of the stroke are crucial, as each location presents different symptoms.
Key Points in the Treatment of Different Recovery Stages of Stroke
Stroke includes ischemic stroke and hemorrhagic stroke, namely cerebral infarction and cerebral hemorrhage. Their treatments are generally opposite. If it is a cerebral infarction, thrombolytic therapy is needed within 4.5 hours of the acute phase. It is necessary to consider whether there are indications and contraindications, and whether the patient and family members agree to undergo thrombolytic therapy. Regardless of whether thrombolytic therapy is administered, it is essential to subsequently check the condition of the cranial vessels to determine if surgical treatment is needed. If surgery is not required, hospitalization for conservative treatment might be necessary. Typically, about 7 to 14 days after the acute phase, rehabilitation treatment may be needed once the patient's condition stabilizes. The duration of rehabilitation treatment usually depends on the patient's recovery progress. Afterwards, it is important to consider the patient's underlying diseases, such as hypertension, diabetes, and other risk factors, to perform secondary prevention, which involves medication and control of risk factors. In the case of cerebral hemorrhage, the treatment during the acute phase depends on the amount and location of the bleeding and whether there are indications for surgery to determine if surgical treatment is necessary. If conservative treatment is chosen, it also involves hospital treatment, followed by possible rehabilitation treatment once stabilized.
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.
What does a stroke cause?
Stroke primarily causes neurological deficits such as limb paralysis in patients. This paralysis is typically hemiplegic, where one side of the body lacks strength, the affected limbs cannot walk, and the upper limbs cannot be lifted. Stroke can also cause numbness in the limbs. Patients may experience reduced pain and temperature sensation on one side of the body, unable to feel pain or temperature. Additionally, stroke can lead to headaches and symptoms such as nausea and vomiting, commonly seen in hemorrhagic strokes, such as cerebral hemorrhage. Furthermore, strokes in specific brain areas like the frontal lobe, temporal lobe, and hippocampus can cause cognitive impairments. Patients become slow to react, have significantly reduced learning and memory capabilities, and their ability to perform daily activities and work is noticeably affected. Strokes can also cause unclear speech, where patients have difficulties in expressing themselves verbally and may even be unable to understand conversations.
Can a stroke be detected through a physical examination?
Patients who have suffered a stroke can definitely be diagnosed if they undergo a head CT scan or MRI during a physical examination. Stroke is classified into hemorrhagic stroke, ischemic stroke, and tumor-induced stroke. A tumor-induced stroke is caused by a tumor, and hemorrhagic stroke includes cerebral hemorrhage and subarachnoid hemorrhage. Ischemic stroke refers to diseases such as cerebral embolism and cerebral infarction. Whether it is a hemorrhagic or ischemic lesion, over time, they tend to form a softening focus. These lesions are difficult to eliminate, and regardless of how many years have passed, these old lesions can still be seen in a head CT scan or MRI. In cases of stroke caused by brain tumors, the changes in size and location of the lesion can also be clearly seen on a head CT scan. Therefore, strokes can be diagnosed during a physical examination of the patients.
What are the types of strokes?
The common types of strokes include hemorrhagic stroke and ischemic stroke. Hemorrhagic strokes commonly involve subarachnoid hemorrhage and intracerebral hemorrhage. Subarachnoid hemorrhage often occurs due to the rupture of cerebral aneurysms, causing blood to enter the subarachnoid space. Intracerebral hemorrhage is commonly caused by hypertension leading to the rupture of cerebral blood vessels and subsequent bleeding into the brain parenchyma. Additionally, there is ischemic stroke, commonly presenting as cerebral infarction and cerebral embolism. Cerebral embolism occurs when a blood clot from another part of the body outside the brain, following the blood circulation, blocks a cerebral vessel. Cerebral infarction happens when cerebral arteriosclerosis narrows down to a certain extent, gradually obstructing and forming cerebral infarction. These are the common types of strokes.
Common clinical manifestations of stroke
Stroke includes ischemic stroke and hemorrhagic stroke, also known as cerebral infarction and cerebral hemorrhage. The clinical manifestations of cerebral infarction depend on the location of the occlusion, and may vary accordingly. Common symptoms include slurred speech and limb weakness. It generally occurs acutely, and may also include memory decline or a series of other symptoms depending on the specific location of the occlusion. If these symptoms occur, it is crucial to seek medical attention immediately, as there is an opportunity for thrombolytic treatment within 4.5 hours. In the case of cerebral hemorrhage, patients may experience symptoms during physical activity, possibly accompanied by severe headaches, as well as symptoms of neurological deficits such as unclear speech, limb weakness, or other symptoms. Seizures may also occur. It is essential to visit the hospital immediately if these symptoms appear. If cerebral hemorrhage is confirmed, the decision for surgical treatment depends on the amount of bleeding.
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.
