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.
Is Parkinson's disease hereditary?
A small portion of Parkinson's disease has a genetic predisposition. According to research statistics, about 5% to 10% of Parkinson’s disease cases are familial, caused by certain gene mutations leading to neurodegeneration. This part of the disease does have a genetic predisposition. However, it does not mean that if the parents have the disease, the child will definitely inherit it; environmental factors are also related. Most cases of Parkinson’s disease do not have a genetic predisposition and are sporadic, possibly related to cerebral ischemia, hypoxia, stress, mitochondrial dysfunction, and long-term exposure to certain toxins. These aspects are definitely not hereditary. Parkinson's disease is a neurodegenerative disorder that can cause symptoms such as bradykinesia, increased muscle tone, and unstable posture. It is important to seek medical treatment promptly.
How to treat myasthenia gravis?
Myasthenia gravis falls under the category of neurological diseases, characterized as an immune disorder of the nervous system, primarily due to the presence of antibodies against acetylcholine receptors. This leads to impaired transmission of nerve impulses to muscles, resulting in various clinical symptoms. The treatment approaches for myasthenia gravis include the following. Firstly, the use of cholinesterase inhibitors is recommended. These medications increase acetylcholine levels and are effective in improving symptoms. Secondly, patients are treated with corticosteroids, typically starting with a low dose and gradually increasing to maintain for a period before reducing the dose again. Adjustments to medication should always be made under the guidance of a neurologist. Third, if the patient has a thymoma, surgical removal is advised.
How to rescue brainstem hemorrhage?
Brainstem hemorrhage is an extremely dangerous disease. Patients typically have a long history of hypertension, and their blood pressure is not particularly well-controlled. The onset of the condition is sudden, and if the bleeding is extensive, it can quickly lead to unconsciousness and even respiratory and cardiac failure, resulting in death. It is crucial to rush the patient to the nearest hospital for emergency treatment to avoid aggravating the brainstem hemorrhage due to bumps during a long transport. Generally, the patient should be kept in a supine position, and if they are still conscious, it is vital to keep their emotions stable. Additionally, it is necessary to ensure the airway remains clear. If respiratory failure occurs, ventilation can be provided. Medications that reduce intracranial pressure can be administered to alleviate brainstem edema. Furthermore, respiratory stimulant drugs can be given to ensure breathing. Overall, the mortality rate for brainstem hemorrhages is exceedingly high, with a lack of particularly effective emergency measures.
