Which department should I go to for a cerebral embolism?
Patients with cerebral embolism need to visit the department of neurology, as it is considered a critical condition in this field. The onset of the disease is sudden and progresses rapidly. Often, in a very short period of time, the condition escalates to a peak, causing the patient to fall into a coma or suffer from complete paralysis of one side of the body. The most common cause of cerebral embolism, and the most frequent source of emboli, is atrial fibrillation, where clots form on the inner walls of the heart; these clots can detach and, carried by the bloodstream, block cerebral vessels. Another common source of emboli is carotid artery plaques, especially soft plaques which are prone to detachment. Once detached, these plaques form emboli that can obstruct major brain vessels, leading to cerebral embolism. Following cerebral embolism, usually larger blood vessels are blocked, causing abrupt blockages in cerebral circulation, and leading to issues with brain blood supply. Generally, this results in extensive brain ischemia, cerebral edema, and brain tissue necrosis. The condition progresses rapidly and requires prompt medical attention and comprehensive hospital treatment.
What department should I register for facial neuritis?
Patients with facial neuritis should make an appointment with the Department of Neurology and seek treatment there. Facial neuritis is caused by infection with neurotropic viruses, which invade the facial nerve and induce inflammation, manifesting as symptoms such as drooping of the mouth corners and facial paralysis. During the acute phase of treatment, it is necessary to use some neuro-nourishing drugs, and appropriate use of steroids can quickly relieve nerve edema and alleviate symptoms. Antiviral drugs can be used during the acute phase, and treatment can be supplemented with infrared radiation to promote local blood circulation. Additionally, after stabilization, most patients can combine acupuncture and physical therapy for treatment a week later. Usually, massaging the paralyzed facial area can promote blood circulation and help repair damaged nerves.

Can migraines be hereditary?
Migraines are not hereditary and are not considered genetic diseases. The onset of migraines is mainly associated with staying up late, fatigue, and the consumption of certain foods that can trigger migraines, such as foods containing nitrites. This includes pickled vegetables, overnight foods, leftover meals, and leftover vegetables, as these contain nitrites, which can trigger migraine attacks. Other triggers include certain dairy products and red wine. To reduce the frequency of migraine episodes, it is advisable to avoid these foods and not to stay up late. When a migraine attack occurs, temporary relief can be sought through oral painkillers. Regular scheduling and avoiding the aforementioned foods can significantly reduce the number of migraine episodes. Therefore, migraines are not hereditary and do not constitute a genetic disease. (Please use medication under the guidance of a professional physician, and do not self-medicate.)
Subarachnoid hemorrhage drainage surgery
Subarachnoid hemorrhage drainage, also known as cerebrospinal fluid replacement surgery, often occurs due to the rupture of cerebral aneurysms. The blood clots enter the subarachnoid space causing severe headaches, increased intracranial pressure, nausea, vomiting, and other symptoms. It is essential to drain the blood clots as early as possible to achieve effective treatment results. The subarachnoid space is a gap between the pia mater and arachnoid mater, which are two of the three membranes covering the brain and spinal cord—the innermost layer being the pia mater, followed by the arachnoid and the outermost dura mater. Normally, the subarachnoid space contains cerebrospinal fluid that is continuously circulating. Hence, in patients with subarachnoid hemorrhage, performing a lumbar puncture can drain the bloody cerebrospinal fluid. During this procedure, a puncture is made in the lumbar region to drain the bloody cerebrospinal fluid, followed by the injection of an equal volume of saline solution. This facilitates the replacement of the blood clots in the subarachnoid space with saline solution. Conducting this procedure once daily, continuously for three to five days, can significantly alleviate the symptoms of subarachnoid hemorrhage. Essentially, this process is also known as cerebrospinal fluid puncture or cerebrospinal fluid replacement surgery.
The causes of facial neuritis are
Facial neuritis, the most common cause, is due to infection by the optic nerve virus. This virus invades the nerves, especially prone to invade the facial nerve, causing damage, inflammation, and edema of the facial nerve, leading to symptoms of facial paralysis, which are manifested as shallower forehead wrinkles, shallower nasolabial folds, widened palpebral fissures, incomplete eyelid closure, and the mouth corner deviating to the opposite side. In the acute phase of treatment, some drugs that reduce nerve edema can be used, along with drugs that nourish the nerves. After the acute phase, when the condition stabilizes, comprehensive treatments such as acupuncture and physiotherapy can be combined. Additionally, the cause of the disease is greatly related to the decrease in the body's immunity. Patients are more likely to become infected and develop symptoms of facial neuritis when their immunity is lowered due to staying up late, exhaustion, and irregular lifestyles.

How to quickly relieve a migraine
Migraines can be quickly alleviated by taking oral painkillers, but this is under the precondition that the diagnosis confirms a migraine attack, rather than some other acute cerebrovascular diseases. If it is an acute cerebrovascular event, taking oral analgesics may mask the symptoms and delay appropriate treatment. Typically, before a migraine attack, there may be premonitory symptoms such as blurred vision or other changes in vision. After these premonitory symptoms appear, headache on one side of the head occurs, and these symptoms may recur. When the symptoms alleviate, they disappear completely. This is a typical migraine attack. Generally, migraines do not pose a major threat to one's health, and symptomatic oral analgesics can quickly relieve the pain. However, it is also necessary to rule out acute cerebrovascular diseases, such as cerebral hemorrhage or subarachnoid hemorrhage, which can also cause headache on one side. If the headache on one side is persistent, a cranial CT scan should be conducted to rule this out. (Please take medications under the guidance of a professional physician.)
How to treat cerebral hemorrhage?
The treatment of cerebral hemorrhage is a comprehensive approach. During the acute phase of cerebral hemorrhage, it is necessary to use some dehydrating and intracranial pressure-lowering drugs to alleviate brain cell edema and prevent the formation of brain herniation, reducing damage to brain cells. Additionally, drugs that eliminate free radicals should be used. During the acute phase, hemostatic drugs can also be used appropriately. Moreover, the most common cause of cerebral hemorrhage is hypertension, so the treatment of cerebral hemorrhage primarily involves stable control of blood pressure, as well as drugs that nourish the nerves, promoting the recovery of damaged brain and nerve cells. Other treatments include the prevention and management of complications such as using anti-infective drugs for concurrent pulmonary infections; for associated gastrointestinal stress ulcers and bleeding, drugs that suppress gastric acid secretion and protect the gastric mucosa along with hemostatic drugs are used, followed by active rehabilitation exercises once the condition is stabilized. Thus, the treatment of cerebral hemorrhage is comprehensive and needs to consider multiple aspects. (Please use medication under the guidance of a professional physician, and do not medicate blindly.)
How to relieve migraines?
Patients with migraines can take oral painkillers to alleviate the pain during an attack. If the patient also experiences nausea, they can take medication to protect the stomach lining and treat nausea and vomiting to relieve symptoms, since migraines do not pose a major threat to one's health. However, it is essential to confirm that the headache is indeed a migraine and not caused by conditions such as cerebral hemorrhage or subarachnoid hemorrhage. Typically, before a migraine attack, there are characteristic prodromal symptoms such as blurred vision or the appearance of wave-like patterns. These symptoms are followed shortly by unilateral or bilateral headaches, which can resolve completely within a few hours even without treatment. These symptoms tend to recur, which are indicative of typical migraines. During an episode, oral painkillers can be taken for relief. To prevent migraines, it is advisable to avoid staying up late, consuming pickled foods, cheese, and red wine as these can trigger migraines. It is recommended to avoid these foods as much as possible. (Medication should be used under the guidance of a doctor.)
Does cervical spondylosis cause dizziness?
Not all cervical spondylosis will cause dizziness. Vertebral artery type cervical spondylosis can cause dizziness due to the hyperostosis of the cervical spine or changes in curvature that compress one of the vertebral arteries. When patients turn their heads to one side, the compressed vertebral artery cannot compensatory increase the blood flow, which does not lead to an increase in blood supply to the brain, resulting in insufficient cerebral blood supply and causing dizziness. A typical manifestation of these patients is that turning the head to one side intensifies the dizziness due to the reasons just mentioned, which is a typical symptom of dizziness caused by vertebral artery type cervical spondylosis. For treatment, drugs that invigorate blood circulation and improve cerebral blood supply are needed, along with cervical physiotherapy treatment. Generally, avoid sitting for too long, don’t use pillows that are too high, and pay attention to protecting your cervical spine. (Please follow professional medical advice for medication usage and do not self-medicate.)
Symptoms of cervical vertigo
Cervical spondylosis dizziness typically occurs in the case of vertebral artery type cervical spondylosis, where the patient experiences episodes or exacerbation of dizziness when turning the head to one side. This is because, in vertebral artery type cervical spondylosis, due to bone hyperplasia or changes in curvature of the cervical spine, one side's vertebral artery is compressed. When the patient turns their head to the other side, the healthy vertebral artery is also compressed. At this time, the vertebral artery compressed by the bone hyperplasia cannot compensatively increase the blood flow, leading to insufficient cerebral blood supply, resulting in symptoms of dizziness or worsening dizziness. This is a typical manifestation of dizziness associated with cervical spondylosis. Treatment includes the use of drugs that invigorate the blood and improve cerebral blood supply, in conjunction with cervical physiotherapy. It is important to protect your cervical spine regularly, and avoid using a pillow that is too high at night. (Please take medication under the guidance of a doctor)
