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.
Symptoms of cerebral atrophy
Mild cerebral atrophy may not present any clinical symptoms, and many elderly people show some degree of cerebral atrophy during imaging examinations, which should not be overly worrying. If the cerebral atrophy is more pronounced, it mainly manifests as cognitive dysfunction, such as a decline in memory, reduced computational abilities, diminished executive functions, and possibly the inability to perform complex movements, such as being unable to brush one's teeth or dress oneself. In severe cases, individuals may experience personality changes, becoming irritable, easily angered, suspicious, and may even exhibit psychiatric symptoms, primarily hallucinations.
How long does it take to wake up from a brainstem hemorrhage?
Brainstem hemorrhage is a very serious condition. If the amount of bleeding in the brainstem increases, the patient will rapidly become comatose and exhibit symptoms such as paralysis of the limbs, inability to swallow, and inability to speak. Generally, if a patient with brainstem hemorrhage falls into a coma and cranial CT confirms a large amount of bleeding in the brainstem, the chances of the patient waking up are very, very slim. If the amount of brainstem hemorrhage is not particularly large and the patient's level of coma is not very deep, treatment may lead to the patient waking up, which could take about two to four weeks. However, the prognosis for brainstem hemorrhage is generally poor, and if the patient falls into a coma, they are usually unlikely to wake up. The treatment for brainstem hemorrhage mainly involves controlling blood pressure and preventing complications. If respiratory failure occurs, timely treatment with a ventilator is necessary. Overall, brainstem hemorrhage has a poor prognosis and high costs.
What tests are conducted for encephalitis?
First, it is generally necessary to conduct an EEG test. This test is very convenient and non-invasive for patients. If significant slow waves are detected, encephalitis cannot be ruled out. Secondly, an MRI of the brain should be performed. If the viral encephalitis is severe, abnormal signals can be observed in areas such as the frontal lobe, temporal lobe, and hippocampus on the MRI, which are of great diagnostic reference value. Thirdly, lumbar puncture is also very important. It allows for a direct observation of the color of the cerebrospinal fluid, to monitor the pressure of the brain fluid, and to test the cerebrospinal fluid for cell count, protein, sugar, and chloride levels. These tests are very important for the diagnosis and differential diagnosis of encephalitis.
Symptoms of facial neuritis
The clinical symptoms of facial neuritis mainly manifest as peripheral facial paralysis, such as the patient's affected side having shallower forehead wrinkles, or disappearing wrinkles, weakened eyelid closure, and in some severe cases, the inability to close the eyes, which can easily lead to corneal damage. There is also noticeable drooping of the mouth corner, a shallower nasolabial fold, and leaking while drinking. The affected individuals are unable to whistle or puff their cheeks. Some patients may also experience disorders in the secretion of salivary and lacrimal glands, taste disturbances at the anterior part of the tongue, and a few may have herpes zoster in the external auditory canal or periosteum with significant pain. The treatment for facial neuritis generally involves the use of corticosteroids.
Main manifestations of pre-stroke warning signs
The precursor of cerebral thrombosis in neurology is called transient ischemic attack (TIA). As the name suggests, this is a transient disease, mainly characterized by symptomatic speech impairment, facial droop, drooling, episodic dizziness, blurred vision, and episodic numbness and weakness of limbs. These symptoms are generally transient, usually lasting from several minutes to a few hours and can be completely relieved. The precursor of cerebral thrombosis is regarded as an emergency in neurology and must be treated promptly. Delayed treatment can possibly progress to cerebral infarction, severely affecting the patient's quality of life and physical health. In considering this disease, one must immediately rush to the hospital for appropriate treatment with antiplatelet drugs, lipid-regulating drugs to stabilize plaques, and treatments such as volume expansion and fluid supplementation.
What is the full name of dementia?
Senile dementia mainly refers to Alzheimer's disease, a condition with a relatively high incidence rate among the elderly population, and it is the most common neurodegenerative disease. The specific causes and mechanisms of this disease are not particularly clear. Under the influence of various factors, degeneration and death of the temporal lobe, hippocampus, and neurons occur, leading to a series of clinical manifestations. Initially, it mainly manifests as a decline in recent memory function, often forgetting recent events. As the disease progresses, there is a decline in calculating ability and judgment, significant spatial dysfunction, personality changes, and psychiatric symptoms.
How to nourish the body after a brainstem hemorrhage
Brainstem hemorrhage is a very dangerous condition. If the bleeding is substantial, the patient may quickly fall into a coma or even die. If the bleeding is less severe, the prognosis might be relatively better. Patients with brainstem hemorrhage typically experience impaired swallowing functions, showing symptoms like inability to swallow food, difficulty in consuming water, and coughing while drinking. Therefore, it is crucial to supplement nutrition. Primarily, a feeding tube can be inserted for hydration and feeding, with the intake mainly consisting of easily digestible foods such as millet porridge, rice porridge, soybean juice, milk, etc. Additionally, it is important to supplement the patient with fresh vegetables and fruits to ensure an adequate supply of vitamin C. Furthermore, high-quality proteins like lean meat and beef should be provided to ensure adequate protein intake for patients with brainstem hemorrhage.
How many days can a migraine recover?
For most cases of migraines, patients generally recover within three days. If migraine-specific medications are administered, recovery can be faster, with symptoms significantly alleviated within a day. If a migraine persists for more than three days without recovery, it is known as a status migraine, and specific migraine medications need to be used, such as ergot preparations or triptan drugs, which are effective. Some patients with prolonged migraine duration may need sedatives and drugs to reduce intracranial pressure for symptomatic treatment. Patients with migraines must ensure adequate rest, ensure good sleep, and maintain stable emotions. (Medications should be used under the guidance of a doctor.)
Pre-symptoms of brainstem hemorrhage
Brainstem hemorrhage is extremely dangerous, and once a massive hemorrhage occurs, the patient can quickly lose consciousness and generally there are no effective emergency measures available. The patient will quickly die due to the involvement of the centers controlling heartbeat and breathing. The early symptoms of brainstem hemorrhage are not particularly obvious, but a careful medical history may reveal that patients often experience excessive fatigue, stress, emotional agitation, and poor sleep before the hemorrhage. Patients may show early signs such as dizziness, blurred vision, double vision, limb weakness, and slurred speech. If a patient has very high blood pressure and exhibits these early symptoms, especially if there is discomfort in the neck and upper back area, it is crucial to be highly vigilant and seek immediate medical attention. The prognosis for brainstem hemorrhage is very poor, thus it is essential to focus on preventive measures and properly control blood pressure.
