Complications of subarachnoid hemorrhage
Subarachnoid hemorrhage is a relatively serious condition. Most patients suffer from this due to the rupture of an aneurysm, while others may have arteriovenous malformations. This disease is associated with complications, with common ones including the following. First, there are acute complications of subarachnoid hemorrhage. Patients usually experience severe pain and vomiting again after their condition stabilizes, and the mortality rate significantly increases. The second complication is cerebral vasospasm, which typically peaks between three days and two weeks. Cerebral vasospasm can easily lead to vascular occlusion and the subsequent formation of cerebral thrombosis. The third type includes acute or subacute hydrocephalus. Additionally, seizures and electrolyte disorders may also occur as complications.
Can people with cerebral infarction eat eggs?
For patients with cerebral infarction, it is acceptable to eat egg whites. Egg whites contain abundant amino acids which can enhance the body's resistance and ensure adequate nutrition for the patient. For cerebral infarction, it is advisable to consume fewer egg yolks. Additionally, egg yolks have a relatively high cholesterol content, which is not conducive to controlling blood lipids in patients. Thus, egg whites can be consumed, but egg yolks should be eaten in moderation. Moreover, patients with cerebral infarction should also consume plenty of fresh vegetables and fruits, which are rich in folic acid and can help fight arteriosclerosis. Additionally, it is beneficial to eat foods rich in unsaturated fatty acids, such as some deep-sea fish and olive oil.
What causes migraines?
Migraine is a relatively common disease, and the possible causes of this disease are as follows: First, it may be related to genetics, with about 60% of migraines being familial, which strongly suggests that genes may be significantly related to the onset of migraines; Second, it is also clearly related to certain internal environments and hormone levels. For example, some women experience migraine attacks during menstruation. Additionally, the triggers for attacks also include drinking alcohol, consuming vasodilator drugs, eating chocolate, and consuming food additives containing sodium glutamate. The pathogenesis of this disease is not yet very clear, and it may be related to vascular dysfunction.
Symptoms of encephalitis vomiting
Patients with encephalitis often experience vomiting, and some even have projectile vomiting. This is mainly because patients with encephalitis experience a significant increase in intracranial pressure, which leads to severe vomiting. Additionally, patients may also have noticeable fever, headaches, and can display swelling of the optic disc. In such cases, it is necessary to promptly administer sufficient antiviral medications to the patient, as well as some medications to dehydrate and reduce intracranial pressure. If necessary, corticosteroids can also be used as an adjunct treatment. With aggressive treatment, some patients do recover well. (Please administer medication under the guidance of a professional physician.)
Does brain atrophy cause dizziness?
If it is brain atrophy, generally it does not cause dizziness; patients with mild conditions may not show any clinical symptoms. If it is severe, the main symptoms are those of dementia, such as possible sluggish reactions, memory decline, reduced computational abilities, impaired executive functions, and even psychiatric symptoms. The most common disease clinically observed is Alzheimer's disease. If the patient has cerebellar atrophy, even mild cases might not exhibit any symptoms. Severe cases can experience dizziness, primarily manifesting as feeling drunk, accompanied by unsteady walking, unstable standing, and other signs of ataxia.
What to eat for senile dementia
For patients with dementia, it is recommended to take some cholinesterase inhibitors, which can increase the content of acetylcholine in the brain and have certain effects on improving cognitive functions. Additionally, consuming NMDA receptor antagonists can also help improve cognition. In terms of diet, it is advised that patients eat more foods rich in unsaturated fatty acids, such as fish, shrimp, and olive oil. It's also beneficial to consume plenty of fresh vegetables and fruits, which are rich in vitamin C and can help combat oxidative stress. Drinking more milk and eating foods rich in B vitamins, mainly whole grains, is also recommended. (Medication should be used under the guidance of a doctor.)
What tests are done for pediatric encephalitis?
Some auxiliary examinations are very necessary for pediatric encephalitis, which help in the diagnosis and differential diagnosis of encephalitis. The main tests generally include the following: First, an electroencephalogram (EEG), which is the most commonly used examination. It is safe, non-invasive, and relatively accurate. Children with encephalitis will show light to moderate abnormalities in the EEG. Combined with the patient's history of fever and headache, it has important clinical significance for the diagnosis of encephalitis. The second important examination is cranial magnetic resonance imaging (MRI). If the encephalitis is severe, pathological changes in the cerebrospinal fluid can be seen on MRI. The third very important examination is lumbar puncture. Lumbar puncture can mainly determine the pressure of the cerebrospinal fluid, the color of the cerebrospinal fluid, and analyze the levels of white blood cells, glucose, and chloride in the cerebrospinal fluid. This is crucial for diagnosing encephalitis and excluding other types of encephalitis.
progression of Alzheimer's disease in the elderly
The progression of dementia in the elderly mainly includes the following aspects. The first is the pre-stage of mild cognitive impairment, during which patients show no clinical symptoms. Some may only report slight memory impairment, with a possible slight decline in learning ability and a mild decrease in the capability to learn new things. As the disease progresses to the second stage, the period of mild cognitive impairment occurs, where patients will experience impaired memory, but it is not particularly obvious, and daily life is not affected at all. Then, entering the third stage, some periods of dementia occur, during which patients' memory, executive abilities, computational skills, and judgment are significantly impaired. Patients might even get lost or possibly forget their own names. As the disease further progresses into the later stages of dementia, the elderly may exhibit some psychiatric symptoms. They become delirious, talk to themselves, and may see things that do not exist. Eventually, the elderly may end up bedridden, with complications such as pulmonary infections and bedsores.
How is brainstem hemorrhage treated?
Brainstem hemorrhage is extremely dangerous and must be treated as soon as possible. The treatment plan mainly includes: the patient must rest in bed, avoid emotional stimulation, ensure smooth bowel movements, and must strengthen turning over and patting the back to prevent serious complications such as bedsores and pulmonary infections. In terms of medication, it mainly involves providing drugs that protect brain cells and nourish brain nerves. Additionally, because patients with brainstem hemorrhage have high intracranial pressure, it is necessary to administer dehydrating drugs to reduce intracranial pressure. Moreover, once the patient's vital signs stabilize, treatments such as acupuncture and rehabilitation training are needed to promote the recovery of neural functions. If the patient experiences respiratory failure, it is necessary to promptly use a ventilator for treatment. Furthermore, patients with brainstem hemorrhage who are bedridden for a long period can develop complications such as pulmonary infections and urinary system infections. If these complications occur, timely use of antibiotics is necessary to control the complications.
How to care for cerebral hemorrhage
Cerebral hemorrhage is a very dangerous neurological disease. In addition to conducting related drug treatments to control the condition, prevent the enlargement of the hemorrhage, and prevent the recurrence of cerebral thrombosis, nursing care is also very important. The nursing of cerebral hemorrhage mainly includes the following aspects: First, it is essential to address the patient's mental state and soothe their emotions because large emotional fluctuations can easily lead to an increase in the amount of cerebral hemorrhage. Second, patients should be advised to rest in bed and avoid vigorous activities. Early ambulation can also easily lead to an increase in cerebral hemorrhage. Third, it is important to maintain smooth bowel movements. If the bowel movements are not smooth, or even constipated, excessive straining during defecation can cause an increase in cerebral hemorrhage. Fourth, patients with cerebral hemorrhage often have some associated complications, such as pulmonary infections and acute ulcers, among other diseases. It is crucial for patients to be attentive to turning over, patting the back, suctioning phlegm, and administering antibiotics in a timely manner if necessary. For the prevention of acute gastric mucosal lesions and acute ulcers, patients should eat soft, easily digestible food.
