Optic neuritis hormonal side effects
Optic neuritis is a demyelinating disease caused by an inflammatory response, a disorder resulting from an immune dysfunction of the body. Thus, corticosteroids play a critical role in its treatment, and are widely used clinically. However, corticosteroids also have some side effects, such as causing osteoporosis, decalcification, and even necrosis of the femoral head, leading to significant obesity in patients due to redistribution of some fats, resulting in conditions like moon face and buffalo hump, and other adverse reactions including acne. Additionally, corticosteroids can have stimulating effects, potentially causing symptoms like insomnia and tachycardia; they also have gastrointestinal side effects, leading to acute ulcers and gastric mucosal lesions.
Can cerebral embolism be treated with thrombolysis?
For patients with cerebral embolism, if the onset is not particularly severe and the area of the embolism is not very large, for example, if the patient's consciousness is still clear, then thrombolysis can still be feasible. It is now also relatively advocated because the risk of cerebral hemorrhage is relatively small in such cases. However, if the area of the cerebral embolism is large, especially if the patient has fallen into a coma or other consciousness disorders, and shows conjugate gaze palsy, then the risk of thrombolysis is very high, and there is a very likely risk of conversion to cerebral hemorrhage. In such cases, thrombolysis is not recommended, and arterial thrombectomy can be performed instead, which can greatly save the patient's life and improve the quality of life. Besides thrombolysis and thrombectomy, anticoagulant therapy should also be administered after the condition stabilizes, as most cases of cerebral embolism are caused by atrial fibrillation, and anticoagulant therapy can prevent future attacks.
What department to see for Parkinson's disease?
Parkinson's disease is a very common degenerative neurological disorder in neurology, so if you go for treatment, you should definitely see a neurologist. Many neurologists have a high level of expertise in Parkinson's disease and have extensive experience in its diagnosis, differential diagnosis, and treatment. Patients with Parkinson's disease generally exhibit significant motor slowness, such as dressing, buttoning, wrapping dumplings, and eating very slowly, and they also walk very slowly. In addition, they may also display obvious resting tremors, muscle rigidity, general fatigue, unstable walking posture, and other clinical manifestations. Moreover, they might experience some constipation, anxiety, depression, and reduced sense of smell among other related clinical symptoms. Therefore, for this disease, visiting a neurologist is sufficient, and you can definitely expect a very satisfactory diagnosis and treatment.
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.
