Causes of Cerebral Infarction
The specific causes of cerebral infarction are mostly seen in older patients with several underlying diseases, such as hypertension, diabetes, and hyperlipidemia. Over time, without well-controlled blood pressure, blood sugar, and blood lipids, arteriosclerosis can easily form within the blood vessels, or atherosclerotic plaques can develop. Once the plaque forms, under certain triggers, the unstable detachment of the vascular plaque can occur. The embolus then moves with the blood flow into the brain and lodges in a narrowed part of the vessel, causing local blood supply areas to experience narrowing or blockage. At this point, a cerebral infarction is likely to form, leading to ischemia, necrosis, and degeneration of the brain tissue supplied by the vessel, resulting in a softening lesion. On a cranial CT scan and MRI, a local low-density shadow can be observed, which is the specific cause of the cerebral infarction.
Symptoms of hydrocephalus in children
For pediatric hydrocephalus, a range of specific symptoms and signs will appear. For instance, children may repeatedly complain of headaches, dizziness, nausea, vomiting, accompanied by a strong sense of vertigo. Through physical examination, it can be found that the head circumference of the child is significantly larger than that of normal children, with the anterior fontanelle full and bulging. Special physical examinations may reveal the presence of a sunset sign or a cracked pot sound. In addition, some children may exhibit certain levels of cognitive dysfunction, lower intellectual development, significantly lagging behind peers, and they might also show instability in walking, swaying back and forth, prone to falling, or even experience urinary and fecal incontinence.
How is hydrocephalus treated?
If hydrocephalus is suspected, it is advised to first visit a local hospital for an emergency cranial CT scan to determine the type and severity of the hydrocephalus. This helps identify the main causes of the condition and whether it is communicating or non-communicating hydrocephalus. Treatment plans should then be based on the patient's symptoms and physical signs. For those with obvious clinical symptoms of obstructive hydrocephalus, surgery is often recommended. Clinically, a ventriculoperitoneal shunt surgery is generally chosen. Through surgical intervention, original symptoms can gradually alleviate or even disappear, and the morphology of the ventricular system can progressively return to normal.
What department should I go to for a cerebral infarction?
When a patient suffers a stroke, it is advised to promptly visit a local hospital and consult a neurologist to assess the condition. Often, when an acute stroke occurs, treatment can be administered through thrombolysis. If the window for thrombolytic therapy is missed, conservative pharmacological treatment is recommended. Clinically, it is generally recommended to treat patients with medications that enhance brain function, promote blood circulation to remove blood stasis, and nourish the nerves. Patients’ vital signs should be closely monitored, and dynamic reassessment through head CT or MRI should be conducted to observe changes in the patient's condition. In cases of extensive stroke, it may be necessary to transfer the patient to neurosurgery for decompressive craniectomy surgery.
Causes of Cerebral Infarction
At present, there is no consensus on the specific causes of cerebral infarction. It is mostly seen in patients with underlying diseases such as hypertension, diabetes, and hyperlipidemia, where there has not been adequate control of the patient's blood pressure, blood sugar, and cholesterol. This can lead to significant increases in blood pressure, blood sugar, and cholesterol. Over time, this might result in the formation of atherosclerotic plaques in the patient’s blood vessels. When these plaques break off and enter the bloodstream, they travel with the blood flow and can lodge in the narrow vessels of the brain. This causes blockage of the blood vessel and leads to ischemia, necrosis, softening, and degeneration of the brain tissue in the affected blood supply area, ultimately causing a cerebral infarction.
Early symptoms of neuroblastoma
For patients with neuroblastoma, the early stages of the disease often manifest as mild headaches, dizziness, nausea, and vomiting. The symptoms are relatively mild and can be significantly alleviated by taking oral pain relief medications. Therefore, the condition often does not receive adequate attention, leading to missed diagnoses. As the tumor size increases, the original symptoms such as headaches and dizziness will significantly worsen. Some patients may even experience optic nerve atrophy, papilledema, reduced visual fields, and vision deficits. When such conditions occur, patients often undergo cranial CT or MRI scans to confirm the presence of neuroblastoma.
What are the symptoms of cerebral hemorrhage?
For patients with cerebral hemorrhage, the symptoms vary clinically due to different amounts of bleeding and instability of the hemorrhage, which affect the surrounding brain tissue to different extents. For patients with minor cerebral hemorrhage, the impact is generally minor, and most patients only exhibit mild symptoms such as headache, dizziness, nausea, and retching. For patients with larger bleeding volumes located in crucial motor and speech functional areas, they often show symptoms such as unilateral limb paralysis and abnormal sensations in the affected limbs, accompanied by significant headaches, dizziness, reduced intellectual levels, cognitive impairments, and even aphasia.
Can pituitary tumors heal on their own?
Under normal circumstances, pituitary tumors generally do not heal spontaneously. Pituitary tumors are benign tumors and although they grow slowly, they tend to continue growing. When they enlarge to a certain extent, they produce a series of symptoms and signs, such as headaches behind the eye sockets, the forehead, and both temporal sides. If the tumor breaks through the sellar diaphragm, it might also affect the optic nerve, leading to decreased vision and visual field defects. Moreover, it can severely erode the pituitary gland, causing symptoms and signs like decreased pituitary function, endocrine hormone disorders, and bringing significant suffering to the patient.
Early manifestations of trigeminal neuralgia
For patients with trigeminal neuralgia, the initial symptoms mainly include sudden onset of intense pain that stops abruptly. The nature of the pain is generally sharp, resembling sharp stabbing or knife-like pain. In most cases, trigger points are easily formed on the face, commonly appearing around the bilateral nostrils and corners of the mouth as fixed trigger points. Touching these trigger points can easily trigger an attack of trigeminal neuralgia, which lasts for a relatively short duration, typically from a few seconds to several seconds. In most cases, attacks are more likely to be triggered when the patient is tired, fatigued, or under mental stress.
Is a pituitary tumor serious?
Pituitary tumors are mostly benign. The tumors grow slowly, but due to their special location adjacent to the pituitary gland, when the size of the pituitary tumor increases to a certain extent, it will inevitably affect the pituitary, impairing its function and leading to pituitary dysfunction. This dysfunction manifests as endocrine hormonal imbalances, resulting in a series of symptoms and signs. Therefore, it is usually recommended to treat pituitary tumors surgically. Clinically, it is generally advised to choose the transnasal transsphenoidal approach for complete resection of the pituitary tumor.
