Does subarachnoid hemorrhage require surgery?
Subarachnoid hemorrhage is a rather dangerous disease with very high mortality and disability rates. It mainly manifests as sudden severe headaches, nausea, and vomiting, and complications such as bleeding, cerebral vasospasm, and electrolyte disorders can occur. The most common cause of subarachnoid hemorrhage is due to the rupture of an aneurysm. Therefore, it is generally advocated that patients with subarachnoid hemorrhage undergo surgery as soon as possible. The surgical method mainly involves local anesthesia, and a complete cerebral angiography is performed to check for the presence of an aneurysm. If an aneurysm is present, an interventional embolization can be performed, which causes less trauma and generally has a better prognosis. If there is a large amount of bleeding and the patient's life is in danger, a craniotomy may also be necessary. Thus, patients with subarachnoid hemorrhage need to undergo surgical treatment.
Why does optic neuritis keep recurring?
The recurrence rate of optic neuritis is quite high because this disease is a type of demyelinating disease of the central nervous system, caused by an immune dysfunction in the body. This immune dysfunction produces abnormal antibodies which attack the optic nerve, as well as the brain and spinal cord, leading to a variety of clinical manifestations. Therefore, as long as the patient's immune function is disordered and not corrected, recurrence is very likely to occur. To prevent the recurrence of optic neuritis, the main aspects include: First, regular physical exercise should be done to enhance physical fitness. Second, it is crucial to follow the doctor's advice and take corticosteroids or other immunosuppressants for a long time, which can help suppress the immune dysfunction. Third, dietary habits should also be carefully managed, with an increased intake of fresh vegetables and fruits and avoiding spicy and stimulating foods.
What is good to eat for subarachnoid hemorrhage?
Subarachnoid hemorrhage is most commonly caused by an aneurysm. Once an aneurysm ruptures, it can lead to blood leaking into the subarachnoid space, causing severe headaches, nausea, vomiting, and other clinical symptoms. The onset is very sudden and the headaches can be extremely intense. It is crucial to treat aggressively and clamp the aneurysm as soon as possible. The diet for patients with subarachnoid hemorrhage should include: First, it is essential to take anti-vasospasm medications, as subarachnoid hemorrhage can easily lead to arterial spasms. Calcium channel blockers should be used to prevent arterial spasms to avoid severe complications. Second, consume foods that aid in bowel movements, such as bananas, apples, and oranges. It is vital for patients with subarachnoid hemorrhage to maintain regular bowel movements, and these foods can help. Third, eat high-quality proteins to strengthen the body and prevent complications. This can include fish, lean meats, beef, and drinking milk.
early signs of dementia
Dementia in the elderly, mainly referring to Alzheimer's disease, is primarily characterized by a significant decline in the patient's memory and learning abilities. Of course, there are some prodromal symptoms before the onset of dementia. For example, patients might show no clinical signs of cognitive impairment or only display very slight memory decline. Patients might exhibit mild impairment in memory, a decrease in the ability to learn and retain new information, and mild impairments in other cognitive areas such as attention, executive function, language skills, and visuospatial abilities. However, these impairments are very slight and can go unnoticed by family members. Moreover, these mild impairments do not affect the patient's basic daily life abilities and do not reach the level of dementia. Patients can live independently and manage their routine daily tasks, which are mainly some of the early signs of dementia.
What is checked for encephalitis?
The examination items for encephalitis mainly include, first, some basic hematological tests. These include routine blood tests, liver and kidney function tests, electrolytes, etc., to understand the status of the patient's white blood cells and whether there is any damage to liver and kidney functions. It is also necessary to test for cardiac enzymes, as some viruses can also affect the heart. Second, an EEG is required. Abnormal EEG patterns, such as increased diffuseness, can be observed in encephalitis, which is important for accurate diagnosis. Third, further examinations like lumbar puncture and cerebrospinal fluid tests are needed. The main focus in cerebrospinal fluid is to see if there is an increase in white blood cells and to check if there are any changes in protein and sugar levels in the fluid. This has great reference value for diagnosing whether it is encephalitis and what type of encephalitis it might be. Fourth, a cranial MRI can be performed to clearly identify if there are any organic lesions in the brain.
Is tremor Parkinson's disease?
Tremor and Parkinson's disease are two completely different concepts. Tremor is not necessarily Parkinson's disease, and Parkinson's disease does not necessarily involve tremor. Tremor is just a clinical symptom that can appear in many diseases. In addition to Parkinson's disease, there are also some essential tremors which are genetic. Patients usually experience tremors in their hands when maintaining certain postures, and may also have head tremors. This is a relatively benign disease with a generally good prognosis. Additionally, patients with hyperthyroidism may also experience limb tremors, but this is not Parkinson's disease. Moreover, many patients with Parkinson's disease experience bradykinesia and rigidity, and might not necessarily have limb tremors. Therefore, these two concepts are different; tremor is not necessarily Parkinson's disease.
Does cerebellar atrophy cause confusion?
Cerebellar atrophy primarily affects the coordination functions of patients, leading to symptoms such as unstable walking and unsteady handling of objects with the hands. This condition does not have a significant connection with human consciousness, and does not affect the reticular structure of the brainstem or the cerebral cortex. Therefore, patients with cerebellar atrophy do not experience confusion or cognitive impairments. If a patient with cerebellar atrophy does exhibit confusion, it is important to consider other possible causes, such as electrolyte disturbances due to poor food intake or concurrent diseases, such as cerebral cortex thrombosis, hemorrhage, or brainstem infarction. It is necessary to conduct additional laboratory tests and cranial magnetic resonance imaging to confirm these conditions.
Is migraine easy to treat?
Migraine, a type of disorder that frequently occurs, causes substantial pain, with patients experiencing severe headaches, nausea, vomiting, and other symptoms. Generally, migraines are manageable and not particularly difficult to treat, although they are prone to recurrence. Treatment primarily consists of pharmacotherapy, including non-steroidal anti-inflammatory drugs for pain relief, as well as specific medications such as triptans and ergot derivatives, all of which are highly effective. Some patients might also benefit from using benzodiazepines, which serve as sedatives and hypnotics, providing favorable outcomes. If migraines frequently disrupt life, preventive medications may be used to decrease their occurrence, including calcium channel blockers and antiepileptics, which are quite effective. (Note: The answer is for reference only. Take medications under the guidance of a professional physician, and do not self-medicate.)
Which department should I go to for a cerebral embolism?
For most hospitals, registration for cerebral embolism requires a visit to the Department of Neurology, which is the most specialized department for treating cerebral embolism. Cerebral embolism generally has corresponding causes, with the most common being heart diseases. For example, conditions such as old myocardial infarction or atrial fibrillation can easily form mural thrombi. These thrombi can detach, enter the cranial arteries through circulation, and cause cerebral embolism, leading to severe clinical consequences. The onset of the disease is very aggressive, quickly reaching a peak and resulting in limb paralysis or even consciousness disorders, requiring emergency treatment. If it is within the thrombolytic time window, intravenous thrombolytic therapy can be administered after assessment. However, one must be cautious of the risk of hemorrhagic transformation during thrombolysis for cerebral embolism. If within a certain timeframe, arterial thrombectomy can also be performed, and many in the Department of Neurology are capable of conducting such surgeries.
sequelae of meningitis
Firstly, it may cause meningitis adhesions leading to hydrocephalus. Once hydrocephalus occurs, it may leave cognitive impairments as sequela, such as slow response, memory decline, and reduced executive functions. Secondly, tuberculous meningitis might also damage cranial nerves, resulting in symptoms such as diplopia, difficulty swallowing with choking on water, and dysarthria. If it affects the facial nerve, peripheral facial paralysis and other sequelae might occur. Thirdly, it could also lead to arteritis. The occurrence of arteritis can cause arterial occlusion, leading to the formation of cerebral infarction.
