What department should I go to for a cerebral embolism?
Brain embolism is a disease in the field of neurology, and one can consult a department of neurology for it. Patients with brain embolism often have a rapid onset, generally with a history of atrial fibrillation. Some thrombi attached to the heart dislodge into the cerebral arteries, causing brain embolism. Symptoms can rapidly develop, including limb paralysis and speech disorders. If the affected area in the brain is large, it may even lead to consciousness disorders and epileptic seizures. For the treatment of brain embolism, interventional thrombectomy can be performed, but there is a strict limitation on the timing window. It should be noted that patients with brain embolism have a high probability of transforming into cerebral hemorrhage, and caution must be exercised during treatment.
Nursing Care of Thrombolytic Therapy for Stroke
Thrombolytic therapy for stroke is an important tool in the treatment of cerebral thrombosis. If administered within the thrombolytic time window, which is currently within four and a half hours from onset, intravenous thrombolytic treatment can significantly save lives and improve the quality of life for patients. Post-thrombolysis care is also crucial, as there are some complications associated with thrombolytic therapy. It is essential to strictly monitor blood pressure after thrombolysis; typically, blood pressure should be checked every 15 minutes, as high blood pressure can significantly increase the tendency for bleeding. During the care process, it is also important to monitor for signs of bleeding such as nosebleeds, bleeding gums, the appearance of petechiae or ecchymosis on the skin and mucous membranes, and any bleeding in the urinary system. Additionally, changes in the patient’s consciousness and limb mobility should be noted. If the patient experiences worsening paralysis or significant headaches, a cranial CT scan must be promptly revisited. In summary, the nursing care following stroke thrombolytic treatment primarily involves monitoring blood pressure, watching for signs of bleeding, and observing changes in limb mobility and consciousness.
Can stroke paralysis be cured?
For a disease like stroke, if paralysis occurs, a small portion of patients can be completely cured without any sequelae. These patients generally are younger in age, receive timely treatment, and do not have a particularly large area of cerebral infarction. However, for the majority of patients, some degree of sequelae is likely to remain. After a stroke, it is crucial to go to the hospital as quickly as possible. If thrombolytic treatment can be administered during the intravenous thrombolysis time window, it can be very effective, and a few patients may even be completely cured. For most patients, further treatment with antiplatelet therapy and rehabilitation training is needed. Although symptoms can significantly improve, complete recovery is relatively difficult.
What is needed to diagnose Parkinson's disease?
The definitive diagnosis of Parkinson's disease primarily relies on the patient's medical history, clinical manifestations, and a thorough physical examination by a neurologist. If the onset of the disease is very slow, presenting with symptoms such as bradykinesia and tremors, and the neurologist observes heightened muscle tone and slow movements during the examination, a high suspicion of this disease is warranted. Additionally, certain auxiliary tests are necessary, commonly including: First, testing the patient's sense of smell is crucial, as a reduced sense of smell is very important in diagnosing Parkinson's disease. Second, some brain MRI scans are needed mainly to exclude some secondary Parkinson's syndromes. Third, a brain PET-CT scan can be performed to examine the functionality of the striatum. Furthermore, an ultrasound of the substantia nigra in the midbrain can also be conducted, which holds significant value in assisting the diagnosis.
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.
What will happen with brainstem hemorrhage?
Brainstem hemorrhage is a very dangerous disease because the structure of the brainstem is so crucial. It contains the life centers responsible for breathing and heartbeat, as well as sensory and motor nerve fibers passing through it. If the brainstem hemorrhage is severe and the amount of bleeding is large, the patient may experience paralysis of the limbs, swallowing dysfunction, and choking on water, among other symptoms. If the condition worsens, it can lead to coma, persistent high fever, and even death. Patients with minor brainstem hemorrhages may exhibit symptoms such as dizziness, nausea, vomiting, numbness in the limbs, and paralysis. Generally, brainstem hemorrhages are caused by hypertension, which must be well controlled.
Pediatric Encephalitis Examination Items
Encephalitis in children is primarily due to a lowered immune resistance, which leads to infection by certain viruses. These viruses invade the nervous system, causing damage to neurons, resulting in symptoms such as fever, headache, nausea, and vomiting. Generally, the main tests for pediatric encephalitis include hematological tests related to bleeding, primarily involving routine blood tests, C-reactive protein, and erythrocyte sedimentation rate. These indices can reflect the inflammatory conditions inside the patient's body, helping to distinguish between viral and bacterial infections. Another very important auxiliary examination is the electroencephalogram (EEG), where pediatric encephalitis can show mild to moderate abnormalities, which is helpful for accurate diagnosis. The third examination involves performing a lumbar puncture to test the cerebrospinal fluid (CSF) for the levels of white cells, glucose, and chloride, which are crucial for diagnosing encephalitis and differentiating it from other types of encephalitis.
Can brainstem hemorrhage be treated abroad?
Patients with brainstem hemorrhage mostly have a risk factor of long-term hypertension, and they usually have poor blood pressure control. This results in small artery lesions, and under emotional excitement or severe fluctuations in blood pressure, bleeding in the brainstem occurs. Brainstem hemorrhage is quite dangerous; many patients who suffer from a significant amount of bleeding in the brainstem can fall into a coma, and some, even if their lives are saved, might end up with paralysis of the limbs or in a vegetative state. Currently, this is a global challenge, and brainstem hemorrhage is generally not advised to be treated surgically. However, some top experts both domestically and internationally have attempted surgical treatment for brainstem hemorrhage, and a portion of patients may see some effects from it, but generally speaking, most hospitals do not advocate for surgical treatment of brainstem hemorrhage. The treatment protocols for brainstem hemorrhage do not vary significantly between countries; the international treatment plans are quite similar.
What is good to eat for Parkinson's disease?
Patients with Parkinson's disease should pay special attention to their diet. It is recommended that the food eaten by Parkinson's patients mainly includes the following types: First, patients can eat more fresh cabbage, vegetables, celery, and fruits such as apples, oranges, bananas, and tangerines, because these fruits and vegetables help supplement some vitamins. Vitamins have an antioxidant stress effect, which may play a role in preventing the further development of Parkinson's disease. Additionally, these foods can supplement water, promote gastrointestinal motility, and alleviate constipation, which is beneficial for the constipation caused by Parkinson's disease. Second, people with Parkinson's disease can eat more walnuts or black sesame seeds, as well as some other nuts, as these foods also nourish brain cells. Moreover, patients with Parkinson's disease must ensure a balanced diet that includes a variety of grains, such as rice, millet, corn, and sorghum, which are all consumable.
Encephalitis belongs to which department?
Encephalitis is primarily a neurological disorder and is an infectious disease of the central nervous system, mainly diagnosed and treated in neurology. There are many causes of encephalitis, with viral encephalitis being the most common. For example, herpes simplex encephalitis is a typical type seen clinically. Patients may experience fever, even with very high temperatures exceeding 40°C, headaches, nausea, and vomiting. If the condition worsens, seizures, coma, and cognitive impairment may occur. These clinical manifestations require further investigations like electroencephalography, cranial MRI, and lumbar puncture. Additionally, there is a specific type of epidemic, known as Japanese encephalitis, which falls under the category of infectious diseases due to its contagious nature.
