What tests are done for a cerebral infarction?
For patients with cerebral infarction, it is recommended to take the patient to a local hospital for timely treatment during the acute phase. A cranial CT scan or MRI should be performed to help assess the current situation. Cranial MRI plays an important auxiliary diagnostic role in identifying the specific location, extent, and severity of the cerebral infarction. It is advised to perform a cranial MRI during the acute phase for a clear diagnosis, and then decide the next step of the treatment plan based on the situation. Within the surgical window, thrombolytic therapy can be applied to achieve dissolution of the clot. If the optimal timing for thrombolysis has been missed, it is recommended that the patient be hospitalized to receive treatment, including intravenous drips, brain-nourishing drugs, nerve nutrition, and medications that invigorate blood circulation and remove blood stasis, to help improve the state of ischemia and hypoxia in the brain tissue.
Glioma Symptoms
For patients with glioma, they often exhibit certain degrees of headache and dizziness, with headaches typically located bilaterally in the frontal or temporal regions. The nature of the pain is relatively sharp, manifesting as intermittent attacks that progressively worsen over time. Long-standing gliomas easily induce a notable increase in intracranial pressure, presenting with severe headaches, nausea, vomiting, and even a decrease in vision or visual field defects. When the glioma is located in the parietal lobe and affects important motor function areas, it can lead to unilateral or bilateral limb weakness, numbness, pain, and possibly even trigger hemiplegia.
Trigeminal neuralgia symptoms display
Trigeminal neuralgia typically manifests as sudden, severe facial pain, most often occurring in areas such as the upper lip, nostril, or corner of the mouth. These areas are prone to forming trigger points, and touching or stimulating these points can provoke an episode of pain. Most often, pain attacks occur when the patient is talking or eating, causing sudden cessation of the activity. The patient may experience unilateral facial muscle spasms, and reactions such as frowning, clenching teeth, opening the mouth wide, covering the eyes, or vigorously rubbing the face with the palm of the hand, leading to rough, thickened skin and eyebrow hair loss.
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.
