Preliminary symptoms of cerebral hemorrhage
Cerebral hemorrhage is a severe and sudden onset condition that usually starts without any prodromal symptoms, manifesting as hemiplegia, severe headaches, or even coma. However, some patients may exhibit certain early symptoms, which mainly include: First, headache, which is not particularly severe, is tolerable, but typically affects the forehead and both temporal areas. Second, patients generally have very high, hard-to-control blood pressure. If the blood pressure is extremely high and difficult to manage, the possibility of cerebral hemorrhage should be considered. Third, in the early stages of cerebral hemorrhage, patients may experience symptoms such as dizziness, blurred vision, and general weakness. Overall, the early symptoms of cerebral hemorrhage are not particularly typical. If a patient with high blood pressure becomes hard to manage, experiences slight headaches, dizziness, blurred vision, and some nausea, these may be indicative of the early symptoms of cerebral hemorrhage.
What is a stroke?
The English term for 脑卒中 is stroke, which generally refers to a group of cerebrovascular diseases. These diseases often onset acutely and mainly consist of two types. The first type is ischemic stroke, which includes diseases like cerebral thrombosis, watershed infarction, cerebral infarction, and cerebral embolism. The second type is hemorrhagic stroke, which primarily includes cerebral hemorrhage and subarachnoid hemorrhage among other bleeding-related disorders. Regardless of the type, the onset of stroke is very sudden, and patients rapidly develop severe neurological deficits. For example, a patient may experience sudden slurred speech, paralysis of one side of the body, or numbness and weakness on one side. There will inevitably be obvious symptoms like dizziness, headache, nausea, vomiting, and stiffness of the neck. If a stroke is suspected, it is crucial to rush to the hospital immediately. Doctors will make an accurate diagnosis and provide appropriate treatment based on the patient's medical history and cranial CT scans.
How to treat mild cerebral atrophy?
First, it is essential to eliminate psychological fear. Many people with mild cerebral atrophy show no clinical symptoms, so there is no need to be overly anxious. Second, it is important to control underlying diseases, especially maintaining control of blood pressure, blood sugar, blood lipids, and homocysteine levels. Abnormalities in these indicators can lead to cerebral ischemia, which in turn may exacerbate cerebral atrophy. Third, make an effort to continually learn new knowledge and master new skills to increase the brain's knowledge reserves and prevent the worsening of cerebral atrophy and the decline in intelligence. In addition, regularly exercising to improve cerebral blood circulation also has therapeutic effects.
Do elderly people with brain atrophy experience dizziness?
If a patient exhibits atrophy of the cerebral cortex, elderly individuals generally do not show clinical symptoms of dizziness. The main manifestations are cognitive impairments, such as a decline in memory, computational ability, and judgment, as well as decreased executive functions. Some severe cases may even show personality changes and exhibit mental symptoms. If the patient has significant cerebellar atrophy, it is possible for them to experience dizziness, such as in cases of multiple system atrophy causing cerebellar atrophy, where the elderly may notably suffer from dizziness, which is related to changes in body position, particularly making them prone to dizziness when standing.
What should not be eaten in case of brainstem hemorrhage?
Firstly, patients with brainstem hemorrhage should avoid eating foods that are difficult to digest. This is because these patients can easily develop acute gastric mucosal lesions, leading to decreased gastrointestinal function. If they consume harder foods, it could increase the burden on their digestive function, which is detrimental to recovery. Secondly, patients with brainstem hemorrhage should also avoid cold items, such as drinking cold beverages or eating ice cream, as these can easily cause diarrhea. Thirdly, patients with brainstem hemorrhage should not eat overly salty foods, such as pickles, salted meat, salted fish, and so on. These items can cause an increase in blood pressure, potentially exacerbating the brainstem hemorrhage. Fourthly, avoid overly greasy foods as they can increase blood lipids, which is also unfavorable for the recovery from a brainstem hemorrhage. Fifthly, patients with brainstem hemorrhage should not smoke or drink alcohol, as these have no beneficial effect on their condition and could instead accelerate the progression of the disease.
incidence of senile dementia
Dementia in the elderly has a very noticeable high incidence trend worldwide and in China, with many people over the age of 65 suffering from this disease. Statistics show that in Western countries, the incidence of dementia in the elderly might be around 3%-8%. In China, the incidence among the elderly over 65 may also be around 5%. Therefore, the number of elderly people suffering from this disease is very large, and thus it is essential to pay attention to this disease. This disease is mainly caused by the death of nerve cells due to many reasons. Currently, there is no effective cure for this disease, but there are some drugs that can alleviate the symptoms. These drugs mainly include cholinesterase inhibitors, which can increase the content of acetylcholine in the brain, improving the level of cognitive function in patients. Additionally, symptomatic treatment should be noted to prevent lung infections, malnutrition, and other complications in the elderly.
Care measures for dementia in the elderly
Dementia in the elderly is the most common neurodegenerative disease in neurology, mainly referring to the irreversible death of neuronal cells caused by various reasons, which poses a significant clinical hazard and lacks effective treatment methods. Therefore, nursing measures become very important. The main nursing measures include, First, ensuring the patient's nutrition. In the later stages, elderly patients may have no regular diet and cannot take care of themselves. Therefore, ensuring sufficient energy intake and enough protein intake is very important. Malnutrition can easily lead to various complications, leading to the patient's death. Second, it's important to equip elderly people with commonly used contact numbers and addresses in their pockets to prevent them from getting lost and creating dangerous situations. Third, when elderly people are at home, it is crucial to keep the kitchen door closed to prevent them from turning on the gas and forgetting to turn it off. Fourth, patients with dementia are prone to lung infections after becoming bedridden. If bedridden, it is important to frequently turn them over and pat their back to prevent the onset of lung infections.
After-effects of encephalitis
Some more serious types of encephalitis may leave sequelae. For example, common ones like herpes simplex viral encephalitis and epidemic encephalitis B. A minority of patients may suffer from certain degrees of sequelae, which typically include the following aspects. Firstly, some patients may experience secondary epileptic seizures, which present with loss of consciousness, limb convulsions, incontinence, and frothing at the mouth. These symptoms might require long-term oral medication for epilepsy. Secondly, another consequence of encephalitis is cognitive impairment in patients, characterized by significant reductions in computational ability, memory, and executive function. Additionally, some forms of encephalitis might leave patients with psychiatric symptoms, such as speaking incoherently.
What does a stroke cause?
Stroke primarily causes neurological deficits such as limb paralysis in patients. This paralysis is typically hemiplegic, where one side of the body lacks strength, the affected limbs cannot walk, and the upper limbs cannot be lifted. Stroke can also cause numbness in the limbs. Patients may experience reduced pain and temperature sensation on one side of the body, unable to feel pain or temperature. Additionally, stroke can lead to headaches and symptoms such as nausea and vomiting, commonly seen in hemorrhagic strokes, such as cerebral hemorrhage. Furthermore, strokes in specific brain areas like the frontal lobe, temporal lobe, and hippocampus can cause cognitive impairments. Patients become slow to react, have significantly reduced learning and memory capabilities, and their ability to perform daily activities and work is noticeably affected. Strokes can also cause unclear speech, where patients have difficulties in expressing themselves verbally and may even be unable to understand conversations.
Treatment of Cerebral Infarction
As society ages, the incidence of cerebral infarction is also increasingly higher, making rational treatment extremely important. Generally, the treatments for cerebral infarction include the following methods: The first point is intravenous thrombolysis, which is a very important treatment plan. If patients can reach the hospital within the thrombolysis time window and are assessed by a neurologist as having no contraindications, they can undergo intravenous thrombolysis treatment, from which many patients benefit. Second, with the advancement of medicine, some patients can also undergo interventional surgery for arterial thrombectomy. Third, the treatment for most patients mainly involves the use of antiplatelet drugs and statins. Additionally, medications that clear free radicals and protect brain cells are provided, along with scientifically-based rehabilitation training.
