Encephalitis MRI manifestations
Encephalitis, commonly referred to, is generally viral encephalitis. Herpes simplex viral encephalitis, a type of viral encephalitis, typically shows distinct manifestations in brain MRI scans. For instance, the patient's MRI may reveal high T2 signals in several areas of the cerebral cortex, particularly in the frontal and temporal lobes, and the hippocampus. If there are subsequent hemorrhagic changes, high signals will also appear on T1-weighted images. Additionally, the MRI of encephalitis may display diffusion-weighted imaging with unusually bright signals, and these signals do not follow a vascular distribution, which strongly suggests encephalitis. Patients with encephalitis generally exhibit significant symptoms such as fever, headache, nausea, and vomiting. In severe cases, they may also experience limb paralysis, psychiatric symptoms, and complications like epilepsy.
What are the symptoms of migraines?
Migraine has a relatively high incidence among many young people, and it is a type of vascular pain, with the following clinical symptoms during the pain episodes. Firstly, the pain usually occurs on one side of the head, but it is important to note that it can also be bilateral. Do not assume it is not a migraine just because the patient experiences pain on both sides of the head. Secondly, the nature of the pain is throbbing headache, and the patient will have a clear sensation of pulsating blood vessels. Thirdly, the patient will experience photophobia, phonophobia, unwillingness to move, and routine activities can exacerbate the headache. In addition, the patient may also exhibit clinical symptoms such as nausea and vomiting, as well as visual abnormalities, such as seeing unusual flashes of light, and may be accompanied by restlessness.
Is there no cure for brainstem bleeding?
Brainstem hemorrhage is one of the most dangerous types of cerebral hemorrhage. Many patients with extensive brainstem hemorrhages quickly fall into a coma because the brainstem is the central hub of human life. It sends fibers that control the heart and breathing, hence, a brainstem hemorrhage affects both heartbeat and respiration. Patients with significant brainstem hemorrhage generally end in death, and surgery does not effectively relieve the hemorrhage. Furthermore, the risks of surgery are very high, and currently, surgery is not recommended. Once a patient with brainstem hemorrhage falls into a coma, their vital signs become unstable, presenting a grave danger. There are no particularly effective emergency measures; treatment is mostly symptomatic, such as the use of ventilators for respiratory difficulties. In cases of infection, treatment predominantly involves the administration of antibiotics to control the infection. Additionally, treatments may include brain protection measures, dehydration to reduce intracranial pressure, and protection of the gastric mucosa. Overall, the outlook after a coma due to brainstem hemorrhage is very poor, with no particularly effective treatment methods available.
Can people with Parkinson's disease drink alcohol?
It is advised that patients with Parkinson's disease should not drink alcohol, as alcohol can damage neurons. The pathogenesis of Parkinson's disease is due to the death of dopaminergic neurons in the substantia nigra, and long-term alcohol consumption can significantly damage neurons. Additionally, patients with Parkinson's disease often take anti-Parkinson's medications long-term. These medications can cause orthostatic hypotension, leading to dizziness in patients. Alcohol itself can also cause orthostatic hypotension, which may exacerbate the adverse effects of the medication and bring negative consequences to the patient. Therefore, drinking alcohol is not recommended. Moreover, drinking alcohol can also increase the risk of falls for patients with Parkinson's disease.
Symptoms of cerebral hemorrhage vomiting
Many patients with cerebral hemorrhage experience nausea and vomiting. This is primarily because the cerebral hemorrhage can significantly increase intracranial pressure. Elevated intracranial pressure can cause nausea, vomiting, and also lead to papilledema. The general treatment for vomiting symptoms caused by cerebral hemorrhage is as follows: First, patients should maintain stable rest and keep a calm mood without large emotional fluctuations. Second, patients can be administered intravenous dehydration drugs to reduce intracranial pressure, which can also alleviate symptoms of vomiting. Third, patients should be fed soft, easily digestible food. Fourth, antiemetic drugs can be injected intramuscularly for symptomatic treatment. (Please use medicines under the guidance of a professional physician and do not self-medicate.)
What is a stroke screening?
Screening for stroke primarily targets high-risk groups, conducting relevant examinations to identify individuals at high risk of stroke and provide timely preventive treatment to prevent the formation of cerebral thrombosis. For example, stroke screening requires thorough checks of blood sugar, blood lipids, and homocysteine levels. It is also necessary to measure the patient's blood pressure and assess the condition of the patient’s blood vessels. This includes carrying out ultrasound scans of the bilateral common carotid, internal carotid, and vertebral arteries, as well as transcranial Doppler or cranial MRA examinations. If a patient exhibits significant cerebral arteriosclerosis with arterial narrowing, they are considered part of a high-risk group and must undergo appropriate interventional treatments.
Does facial neuritis cause the tongue to be crooked?
Patients with facial neuritis should not exhibit a crooked tongue, as the tongue is governed by the hypoglossal nerve, which is not directly related to facial neuritis. If a patient does have a deviated tongue when sticking it out, it’s crucial to consult a neurologist, undergo a cranial MRI to rule out any new cerebral infarction. Patients with facial neuritis mainly exhibit symptoms of peripheral facial palsy, such as deviation of the mouth, drooping of the mouth corners, drooling, and inability to blow cheeks or whistle. They may also experience a reduction or disappearance of forehead wrinkles, and may find it difficult to open or close their eyes. Prompt intervention and treatment are necessary.
Where to treat migraine?
Migraine is a common disease in neurology, so if a patient suffers from migraines, they definitely should seek treatment in neurology. Neurologists have extensive clinical experience in the diagnosis, differential diagnosis, and treatment of migraines. This is a very classic type of vascular headache, which is significantly related to disorders in vascular constriction and dilation functions. Some studies also suggest that it may be related to trigeminal vascular complex lesions. In this regard, the main treatment for patients involves the use of non-steroidal anti-inflammatory painkillers for symptomatic treatment. If the headache is severe, ergot preparations or triptans may be administered for treatment. (Please use medicine under the guidance of a professional physician.)
Myasthenia gravis should see which department?
Myasthenia gravis is a common disease in neurology, so when visiting the hospital, it is definitely necessary to see a neurologist. Neurologists have certain experience in diagnosing and treating this disease. This disease is classified as a neuromuscular junction disorder, mainly caused by the production of antibodies against acetylcholine receptors in the body. This leads to the nerve impulses not being effectively transmitted to the muscles, resulting in clinical manifestations. Patients' symptoms include improvement in the morning and worsening in the evening, fluctuating symptoms, and may present with drooping eyelids, double vision, general weakness, and some patients may also experience difficulty swallowing and speech disorders.
Can people with myasthenia gravis smoke?
Patients with myasthenia gravis are advised not to smoke. It is best to avoid smoking because myasthenia gravis is a disease caused by an autoimmune disorder, and smoking can further damage the body's immune function, leading to an exacerbation of the disease. Additionally, patients with myasthenia gravis may experience disturbances in respiratory function, leading to insufficient breathing and are highly susceptible to complications like lung infections. They are particularly at risk of respiratory infections, which can trigger a myasthenia gravis crisis, and in severe cases, can endanger the patient's life. It is well known that smoking has a very negative impact on the lungs and respiratory tract, easily damaging bronchial cells and inducing bronchial infections. Therefore, smoking-induced infections can cause acute exacerbation in patients with myasthenia gravis, and in severe cases, even threaten the patient's life safety.
