How long can someone with Parkinson's disease live?
Parkinson's disease is a degenerative disease of the nervous system. It has a slow and inconspicuous onset, and it progresses gradually. The disease itself does not affect the patient's lifespan, as it does not impact the functions of heartbeats or breathing. If treated properly, cared for promptly, medications are taken as prescribed by the doctor, and followed up long-term, patients can survive about twenty years without problems. However, if patients adjust their medications on their own, stop taking their medications without consultation, or receive improper care from family members leading to accidental injuries or complications such as lung infections, then their lifespan can be significantly shortened. Once bedridden, life expectancy may rapidly decline. Therefore, with proper treatment and care, patients with Parkinson's disease can survive for about ten to twenty years. If care and treatment are not managed properly, patients may be threatened by fractures or lung infections, potentially reducing their lifespan to about five to ten years.
What to do about urinary incontinence in dementia in the elderly?
Dementia in the elderly is a degenerative neurological disease, and there are currently no particularly effective treatments. In the later stages, it is very common for the elderly to experience urinary incontinence. This is mainly because in the later stages, the autonomic nervous system is affected. Damage to the autonomic nerves leads to dysfunction of the sphincter muscles, resulting in urinary incontinence. Currently, there are no particularly good treatments for urinary incontinence caused by dementia, but some common methods are as follows. First, it is important to kindly remind and encourage the elderly to go to the bathroom frequently, asking every one to two hours whether they feel the need to urinate, which can help avoid urinary incontinence. Second, bathrooms must have conspicuous signs that are prominently placed to help the elderly locate the restrooms easily. Third, when necessary, the elderly can be given diapers to wear to avoid embarrassment from wetting their pants. Also, it's crucial to provide psychological comfort to the elderly and avoid causing them excessive psychological burden. Additionally, other causes must be ruled out. If there is a urinary tract infection or some other urinary system disease causing the incontinence, treatment of the primary disease should be undertaken.
Optic neuritis treated with steroids
Optic neuritis is a demyelinating disease of the central nervous system, primarily including optic neuritis caused by multiple sclerosis, as well as neuromyelitis optica and retrobulbar neuritis, among others. These diseases are caused by abnormal immune responses of the body and are closely related to immune dysfunction. Therefore, optic neuritis is mainly treated with corticosteroids. Corticosteroids can inhibit the body's immune response to achieve the purpose of alleviating the disease. However, the use of steroids should also pay attention to some related risks. For instance, there might be occurrences of osteoporosis and even osteonecrosis of the femoral head, potential disturbances in electrolyte, fat, and sugar metabolism in the body, the possibility of developing centripetal obesity, and the potential for gastric ulcers. Close monitoring is essential, and other immunosuppressants may be added if necessary. (Use of medications should be under the guidance of a doctor.)
Can facial neuritis be cured?
Facial neuritis is a relatively common disease in neurology. It is mainly caused by viral infection or other nonspecific inflammatory reactions, leading to local inflammation of the facial nerve, which results in edema of the facial nerve and clinical manifestations caused by compression within the facial nerve canal. The main symptoms include shallower furrows on the affected side of the forehead, weakness in opening and closing the eyes, drooping and skewing of the mouth corner, drooling, weakness in puffing the cheeks, and air leakage when puffing the cheeks. Most patients with facial neuritis have a good prognosis, as long as the diagnosis is clear and appropriate treatment is administered in a timely manner, such as treatment with corticosteroids and B vitamins. If it is caused by a viral infection, appropriate antiviral treatment is given, and most patients can fully recover in about three months. If the condition is severe at the onset, or if the patient has risk factors such as diabetes, the prognosis is not very good. Overall, most people with facial neuritis recover well.
How long will it take for the migraine to get better?
Migraine is very prevalent among young and middle-aged people, with sufferers usually experiencing unilateral, though sometimes bilateral, pulsating headaches. These may accompany a sensitivity to light and sound, along with significant nausea and vomiting. Typically, migraines resolve within 4-72 hours, meaning recovery generally occurs within three days. If it doesn’t resolve within three days, it’s referred to as a status migrainosus. During an acute migraine episode, it is important to rest, ensure adequate sleep, consume more fruits, and take non-steroidal anti-inflammatory drugs for treatment. Specific pain relievers such as triptans may also be used, and concurrent complications should be addressed. Furthermore, if migraines recur frequently, prophylactic treatment with medications like beta-blockers may be considered. (Please consult a professional physician before taking any medication.)
What is good to eat for myasthenia gravis?
Myasthenia gravis is an autoimmune disease of the nervous system that primarily affects the neuromuscular junction, leading to muscle weakness and post-exertional fatigue. Some patients may also experience clinical symptoms such as ptosis and diplopia. The main treatments include corticosteroids and immunosuppressants. Patients with myasthenia gravis should pay attention to their diet: First, consume plenty of fresh vegetables and fruits, which are rich in vitamins that can provide sufficient immunity to prevent certain complications. Second, eat foods high in B vitamins, such as animal liver, lean meat, and whole grains, which are beneficial for patients. Third, patients should also consume high-quality proteins, which provide ample nutrition and increase resistance, including items such as milk, beef, and fish.
MRI manifestations of brain atrophy
Patients with cerebral atrophy display clear signs on cranial Magnetic Resonance Imaging (MRI). The manifestations on MRI primarily include notably widened cerebral sulci, obvious atrophy of the cerebral lobes, and enlarged ventricles, which are typical presentations of cerebral atrophy. Cerebral atrophy can be categorized into atrophy of the cerebrum, cerebellum, and brainstem, each showing different characteristics on MRI, which requires careful differentiation. There are many causes of cerebral atrophy, such as degenerative diseases like Alzheimer's disease, which leads to cerebral atrophy. Cerebral thrombosis and poor cerebral vascular conditions can also cause cerebral atrophy due to insufficient blood supply to the brain. Additionally, drug toxicity and chronic alcoholism can lead to cerebral atrophy, which also needs to be differentiated carefully.
Alzheimer's disease is also called dementia.
Alzheimer's disease, also known as dementia in the elderly, was first identified abroad and thus named after the discoverer, Alzheimer. It is one of the most common neurodegenerative diseases in neurology, with a very high incidence among people over 65 in China and worldwide. The disease mainly affects patients' cognitive functions. Initially, patients do not meet the criteria for dementia and primarily exhibit a decline in memory. As the disease progresses, the decline in memory worsens, and patients begin to forget both recent and past events. Additionally, they may experience impairments in visuospatial abilities, judgment, comprehension, and learning capabilities. In the later stages, psychiatric symptoms and personality changes may appear, such as visual hallucinations, shouting, and gesturing wildly, among various other clinical manifestations.
Can cerebellar atrophy be cured?
Cerebellar atrophy is difficult to cure. There are many causes of cerebellar atrophy, such as degenerative diseases of the nervous system. For example, olivopontocerebellar atrophy, which is caused by a disease with an unknown pathogenesis leading to the death of cerebellar cells and resulting in atrophy, currently lacks effective treatment methods and is incurable. Some cases are due to hereditary diseases, such as spinocerebellar ataxia, where patients also suffer from cerebellar atrophy, making it very difficult to cure. In addition, some patients who have been chronically drinking alcohol can also develop cerebellar atrophy due to alcohol poisoning. Although clinical symptoms can be significantly improved by discontinuing alcohol use and administering large amounts of vitamin B1 and B12, the atrophy in the cerebellum cannot be reversed as seen on imaging studies.
How to alleviate myasthenia gravis?
Myasthenia gravis is a disease of the department of neurology and its incidence is not low, it is also relatively common clinically. The treatment of myasthenia gravis mainly includes the following points: First, if patients with myasthenia gravis also have a thymoma, it is recommended to surgically remove the thymoma as soon as possible, which can significantly alleviate the symptoms of myasthenia gravis and reduce the amount of medication needed. Second, provide patients with some medication, mainly some drugs that suppress the immune response, including some corticosteroids. The use of corticosteroids is relatively complex, and must be gradually increased or decreased under the advice of a doctor. Do not stop taking them on your own. There are also some drugs that are cholinesterase inhibitors, which can increase the content of acetylcholine in the synaptic gap, alleviating the patient's symptoms. In addition, research has confirmed that some new immunosuppressive agents can also be used in the treatment of myasthenia gravis. In summary, the treatment of myasthenia gravis is a comprehensive subject and must be tailored according to the patient's condition.
