What is a stroke?
Stroke primarily refers to cerebrovascular disease. Acute onset of stroke usually presents with focal neurological deficits, mainly divided into ischemic and hemorrhagic strokes. Ischemic stroke, primarily referring to cerebral infarction, occurs due to an interruption in the blood supply to the brain, causing vessel occlusion and resulting in various clinical syndromes. Clinically, it presents rapidly with symptoms such as limb paralysis, slurred speech, and facial drooping. The pathogenesis of ischemic stroke is caused by central arteriosclerosis of large vessels. Additionally, stroke also includes cerebral embolism, mainly referring to atrial fibrillation-induced emboli from wall-attached thrombi, and other foreign bodies causing embolic blockage, leading to necrosis of brain tissue. Stroke also encompasses hemorrhagic stroke, with a typical condition being cerebral hemorrhage, which is due to long-term hypertension causing hyaline degeneration of the small arterial walls, eventually leading to necrosis and rupture with bleeding, resulting in neurological deficits.
What to do about migraines?
Migraine prevalence is relatively high, and for those experiencing migraines, the following treatments are recommended: First, it is essential to maintain a calm emotional state and avoid excessive stress. Secondly, medication can be used for treatment. Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used and are effective for many patients. However, if there is no relief after taking these, or if the pain is very severe, medications specifically for treating migraines such as ergot derivatives and triptans may be prescribed. Third, if the migraine is accompanied by nausea and vomiting, antiemetic drugs can be used. Additionally, if the patient with migraine also experiences significant restlessness or anxiety, an appropriate amount of sedative medication can be applied. (Please use medication under the guidance of a doctor.)
Can Parkinson's disease be cured?
Firstly, it must be noted that Parkinson's disease is a neurodegenerative disease which currently cannot be cured. Although Parkinson's disease cannot be cured, there are many methods available to slow the progression of the disease and improve the quality of life for patients. Patients must take medication regularly under the guidance of a doctor. The treatment methods for Parkinson's disease mainly include: First, patients should strengthen their functional training and engage in as much physical activity and exercise as possible, which can help in treating the disease. Second, regular medication is necessary, mainly referring to drugs used for treating Parkinson's disease. These include dopamine receptor agonists, anticholinergic drugs, and Levodopa preparations, all of which can have good effects, but these medications also have certain side effects and require regular follow-up visits at outpatient clinics. (Specific medications should be taken under the guidance of a physician.)
How to alleviate senile dementia?
Dementia brings a heavy burden to both the patient and their family, severely affecting the quality of life. Fundamentally, there is no particularly effective treatment for this disease. To achieve relief, the following measures are recommended: Firstly, it is generally necessary for the patient to take medication for treatment. Commonly used medications include cholinesterase inhibitors, which can increase the content of acetylcholine in the brain and can to some extent delay the progression of the disease. In addition, one can also take some NMDA receptor antagonists to improve dementia. Secondly, encourage the elderly to learn more and read more, which can increase knowledge reserves and delay progression. Thirdly, it is essential to encourage the elderly to go out and interact with others, and of course, precautions should be taken to prevent them from getting lost. In addition, they should engage in appropriate aerobic exercise. (Specific medication use should be conducted under the guidance of a doctor)
Six Common Manifestations of Stroke
Firstly, patients may experience language impairment, primarily characterized by unclear speech or sensory aphasia, where they cannot understand others' conversations. Secondly, motor dysfunction is also a very common symptom, typically presenting as hemiplegia on one side of the body. Thirdly, sensory dysfunction can occur, manifested as numbness in one side of the body, an inability to feel pain, and an inability to sense temperature. Fourthly, there may be signs of ataxia, such as unstable walking or standing. Fifthly, there may be difficulties in swallowing, coughing while drinking water, and articulation disorders. Lastly, cognitive dysfunction can also occur, characterized by slow responsiveness and similar symptoms.
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.
What is the cause of swollen feet after a stroke?
Patients with cerebral infarction presenting with swollen feet and lower limb edema should be aware of the following reasons. The first scenario is due to reduced activity in the limbs on the paralyzed side, which results in weaker muscle contraction. Consequently, a large amount of blood accumulates in the lower limb veins, causing poor circulation and naturally leading to swollen feet. Therefore, it is crucial for patients to begin early rehabilitation training, engage in muscle massage, and perform passive joint exercises, among other activities. The second scenario that requires close attention is the formation of venous thrombosis in the lower limbs on the paralyzed side after a cerebral infarction. This condition can easily lead to venous thrombosis, which significantly contributes to foot swelling. Furthermore, it increases the risk of pulmonary embolism. It is important to complete routine coagulation tests and d-dimer examinations, as well as comprehensive lower limb venous Doppler ultrasound assessments.
Late-stage symptoms of senile dementia
Elderly dementia generally refers to Alzheimer's disease. This disease begins slowly and progressively worsens, with symptoms becoming increasingly severe. In the later stages of dementia, symptoms are numerous, mainly reflected in the following aspects: First, patients may exhibit significant personality changes. For example, a person who was originally gentle may become irritable and prone to aggressive behaviors such as hitting or yelling at others, and may even experience incontinence. Second, a patient's overall cognitive functions completely collapse, with a comprehensive decline in memory, as well as significant impairments in computational abilities, judgment, and comprehension. There are also problems with time orientation, with patients unable to distinguish between day and night. Additionally, patients may experience severe malnutrition, develop bedsores, and suffer from serious complications such as pulmonary infections and urinary tract infections.
Does myasthenia gravis require hospitalization?
Myasthenia Gravis is a type of neuroimmune disease within the field of neurology which fundamentally stems from issues with the patient's own immune function. Whether hospitalization is necessary depends critically on the severity of the disease. If Myasthenia Gravis manifests only as ocular symptoms, such as ptosis and double vision, hospitalization is generally not necessary. It is important to take certain medications, primarily cholinesterase inhibitors and corticosteroids, but regular outpatient follow-ups are essential. However, if Myasthenia Gravis is generalized, with noticeable whole-body weakness, particularly if accompanied by swallowing difficulties and coughing while drinking, hospitalization is required. If a myasthenic crisis occurs, presenting with respiratory muscle weakness and breathing difficulties, hospitalization is certainly needed, and admission to the ICU might be necessary.
Does brainstem hemorrhage easily recur?
The main cause of brainstem hemorrhage is hypertension, which can lead to hyalinization in the arteries that supply the brainstem, and even the formation of small aneurysms. Under the impact of blood flow, these are prone to rupture, leading to hemorrhage in the brainstem. This is the primary mechanism of onset for brainstem hemorrhage. If the brainstem hemorrhage is caused by hypertension, maintaining good control of blood pressure and keeping it below the ideal level of 140-90 mmHg can prevent frequent recurrence, so there is no need for excessive worry, but it is crucial to monitor blood pressure regularly. Additionally, brainstem hemorrhages can also be caused by other reasons, such as cavernous hemangiomas or arteriovenous malformations. If brainstem hemorrhage is caused by these diseases, and the abnormal vessels are not surgically removed, recurrence is likely. Removing these abnormal vessels can greatly reduce the likelihood of recurrent brainstem hemorrhages.
