Chronic subdural hematoma is an accumulation of intracranial hemorrhage between the dura mater and the arachnoid, and the hematoma liquefies and compresses the surrounding brain tissue, resulting in headache, dizziness, and vomiting three weeks after traumatic brain injury. It occurs mostly in the elderly and children, accounting for about 10% of intracranial hematomas, and is the most common neurosurgical disease in the world. According to the literature, its lethality rate is about 5-16%, and it is a disease that should not be ignored, so it is necessary for everyone to understand this disease. What exactly are the symptoms of chronic subdural hematoma? Most patients have a history of minor traumatic brain injury, especially the elderly when the frontal or occipital force, prone to subdural hemorrhage, and for patients with a previous history of coronary heart disease, cerebral infarction and long-term oral aspirin, clopidogrel, more likely to occur, so such patients occur traumatic brain injury should pay more attention to, to improve the head CT examination in a timely manner to the hospital, and regular re-examination. The symptoms of chronic subdural hematoma mainly include headache, dizziness, weakness, mental decline, hemiparesis, and rarely epilepsy or stroke-like seizures. Dementia and mental abnormalities are common in elderly people, and are easily confused with brain tumors and hydrocephalus; pediatric patients often have symptoms such as drowsiness, enlarged head, prominent fontanelle, and convulsions, which are similar to hydrocephalus symptoms. Because many patients with chronic subdural hematoma require surgery, which has certain risks, people surely want to know if there is a drug to treat this disease. After years of research by neurosurgeons, it was found that atorvastatin calcium tablets are more effective for chronic subdural hematoma, so there is a drug available for chronic subdural hematoma. However, we should not just believe in the therapeutic effect of drugs. For patients with more severe symptoms and a larger amount of hematoma with midline shift, surgical treatment is still recommended. Therefore, the kind of treatment needed for patients with chronic subdural hematoma must be decided only after examination and evaluation by a neurosurgeon, and one cannot miss the treatment time by taking oral medication on one’s own.
