How is encephalitis transmitted?
The commonly mentioned encephalitis is mainly caused by viral infections. There are many types of viruses that can cause encephalitis, including the more severe herpes simplex virus, varicella-zoster virus, etc. There are also some enteroviruses, like Coxsackie virus, and some adenoviruses. Typically, the transmission of encephalitis can occur via the fecal-oral route, where some enteroviruses enter the digestive tract through this route, then from the cells of the digestive tract to the bloodstream, and from there to the brain. Additionally, some viruses are transmitted through blood contact. For instance, if a patient has blisters that rupture and release a large amount of virus, and another person's blood comes into contact with these fluids, transmission can occur via blood. Generally, encephalitis is primarily transmitted through fecal-oral routes and bloodborne transmission.
Does cerebellar atrophy cause dizziness?
Patients with cerebellar atrophy may experience dizziness. In clinical practice, multiple system atrophy that leads to cerebellar degeneration and spinal cerebellar ataxia often present with symptoms of dizziness. Generally, dizziness is very common when there is a lesion in the cerebellum. However, some patients may show significant cerebellar atrophy on imaging but actually do not exhibit symptoms of dizziness. Therefore, the condition can vary from person to person. There are many causes of cerebellar atrophy, including some cerebrovascular diseases that can lead to cerebellar atrophy, with symptoms such as dizziness and ataxia. The key to treating cerebellar atrophy is to properly identify and address the underlying cause.
Does encephalitis require hospitalization?
The severity of encephalitis can vary greatly; it is generally caused by viral infection. Among these viruses, Herpes Simplex Virus (HSV) is particularly dangerous. Encephalitis caused by HSV can be very severe, with symptoms including high fever, headache, nausea, vomiting, and other serious manifestations. Some patients may even experience seizures, coma, cognitive decline, and changes in mood and behavior. This type of encephalitis is very severe and definitely requires hospitalization. Typically, hospitalization lasts about 2 to 3 weeks, and proper antiviral treatment is necessary. Additionally, there are other forms of encephalitis caused by different viruses that are relatively milder and may even have a certain degree of self-healing properties. Generally, resting well, drinking plenty of water, and consuming fresh vegetables and fruits can lead to recovery. Therefore, whether hospitalization is necessary for encephalitis depends on the severity of the condition and the assessment of which virus has caused the infection. It cannot be generalized.
What are the symptoms of Parkinson's disease?
Parkinson's disease is a relatively common disease among the elderly, causing significant inconveniences in their daily lives and making it difficult for them to move. Moreover, this disease progressively worsens. Overall, the symptoms of Parkinson's disease primarily include noticeable movement slowness; patients perform tasks very slowly, such as wrapping dumplings or rolling dumpling wrappers, which are done clumsily and slowly. They also dress, turn over in bed, and tie shoelaces very slowly. Additionally, there are evident symptoms such as resting tremors and muscle rigidity. Some people may experience a panicked gait, rushing forward and unable to control their steps. Patients might also experience severe constipation, a reduced sense of smell, and some have sensory abnormalities in their limbs.
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.
