Is Parkinson's disease hereditary?
A small portion of Parkinson's disease has a genetic predisposition. According to research statistics, about 5% to 10% of Parkinson’s disease cases are familial, caused by certain gene mutations leading to neurodegeneration. This part of the disease does have a genetic predisposition. However, it does not mean that if the parents have the disease, the child will definitely inherit it; environmental factors are also related. Most cases of Parkinson’s disease do not have a genetic predisposition and are sporadic, possibly related to cerebral ischemia, hypoxia, stress, mitochondrial dysfunction, and long-term exposure to certain toxins. These aspects are definitely not hereditary. Parkinson's disease is a neurodegenerative disorder that can cause symptoms such as bradykinesia, increased muscle tone, and unstable posture. It is important to seek medical treatment promptly.
How to treat myasthenia gravis?
Myasthenia gravis falls under the category of neurological diseases, characterized as an immune disorder of the nervous system, primarily due to the presence of antibodies against acetylcholine receptors. This leads to impaired transmission of nerve impulses to muscles, resulting in various clinical symptoms. The treatment approaches for myasthenia gravis include the following. Firstly, the use of cholinesterase inhibitors is recommended. These medications increase acetylcholine levels and are effective in improving symptoms. Secondly, patients are treated with corticosteroids, typically starting with a low dose and gradually increasing to maintain for a period before reducing the dose again. Adjustments to medication should always be made under the guidance of a neurologist. Third, if the patient has a thymoma, surgical removal is advised.
How to rescue brainstem hemorrhage?
Brainstem hemorrhage is an extremely dangerous disease. Patients typically have a long history of hypertension, and their blood pressure is not particularly well-controlled. The onset of the condition is sudden, and if the bleeding is extensive, it can quickly lead to unconsciousness and even respiratory and cardiac failure, resulting in death. It is crucial to rush the patient to the nearest hospital for emergency treatment to avoid aggravating the brainstem hemorrhage due to bumps during a long transport. Generally, the patient should be kept in a supine position, and if they are still conscious, it is vital to keep their emotions stable. Additionally, it is necessary to ensure the airway remains clear. If respiratory failure occurs, ventilation can be provided. Medications that reduce intracranial pressure can be administered to alleviate brainstem edema. Furthermore, respiratory stimulant drugs can be given to ensure breathing. Overall, the mortality rate for brainstem hemorrhages is exceedingly high, with a lack of particularly effective emergency measures.
Does facial neuritis need treatment?
Facial neuritis, also known as idiopathic facial paralysis, can self-heal in a minority of patients with very mild symptoms without treatment. However, for most patients, it is still recommended to seek treatment promptly as it involves a non-specific inflammatory response. Treatment mainly involves the use of corticosteroids to reduce inflammation and swelling of the facial nerve. Additionally, treatment with B vitamins such as commonly used B1 and vitamin B12 is necessary, as these can nourish the peripheral nerves. Furthermore, patients also need to undergo some physical therapy and rehabilitation training. (Please use medication under the guidance of a professional physician.)
Stroke and Its Treatment
Stroke primarily refers to cerebrovascular disease, characterized by the sudden onset of symptoms that develop within minutes. This rapid development of symptoms is why it is called a stroke. Stroke commonly affects middle-aged and elderly people who often have certain risk factors. For example, high blood pressure, high blood cholesterol, smoking, drinking, obesity, and heart diseases like atrial fibrillation can increase the risk of stroke. For the treatment of stroke, it is crucial to reach the hospital as soon as possible, as earlier treatment leads to better outcomes. Generally, if it is suitable, the patient may receive intravenous thrombolysis. Additionally, treatment may involve anti-atherosclerosis measures, nutritional support for nerves, and rehabilitation training, which is also very important.
Can Parkinson's disease be cured?
Parkinson's disease is a movement disorder, and there are many medications and treatments that can improve the quality of life for patients and alleviate their clinical symptoms. However, from the current medical perspective, it is impossible to achieve a complete cure. Therefore, patients with Parkinson's disease must not be deceived and should seek treatment at accredited hospitals. Currently, treatment for this disease primarily involves pharmacotherapy. There are various medications available, commonly including dopamine receptor agonists, Levodopa-based drugs, as well as some amantadine and anticholinergic drugs. Each drug has its own characteristics and should be chosen based on the patient's condition. Additionally, some patients in the middle or later stages may also undergo deep brain stimulation surgery to improve symptoms. (Please use medication under the guidance of a professional physician and do not medicate blindly.)
Is subarachnoid hemorrhage hereditary?
Subarachnoid hemorrhage occurs due to the rupture of intracranial blood vessels and the subsequent leaking of blood into the subarachnoid space. In most cases, this condition is caused by the rupture of an aneurysm. This disease does not have a significant genetic predisposition, so there is no need for excessive worry. The common causes of this disease are primarily intracranial aneurysms, followed by vascular malformations. It should be noted that arteriosclerosis can also lead to the formation of aneurysms, and long-term smoking can also cause aneurysms. Subarachnoid hemorrhage often begins abruptly, and the patient might be engaged in some physical activity or experiencing fluctuating emotions when suddenly severe headache, nausea, vomiting, and even consciousness disturbances occur. It is essential to treat a subarachnoid hemorrhage as soon as possible.
Subarachnoid hemorrhage sequelae
Subarachnoid hemorrhage is a rather dangerous disease that develops very suddenly, most often caused by the rupture of an intracranial aneurysm. Some patients may not have any sequelae, but some severe cases can result in lasting consequences. Common sequelae include the following aspects: First, hydrocephalus. This condition can lead to adhesions of the meninges and can cause blood to remain in the subarachnoid space and the ventricles, potentially causing fluid accumulation. Second, there may be residual epileptic seizures. If epilepsy is a sequela, long-term oral anti-epileptic drugs are required. Third, some patients may experience cerebral vasospasm, leading to secondary cerebral infarction, which can leave patients with limb paresis and language impairments.
How to care for senile dementia
In the later stages of dementia, patients exhibit a variety of clinical symptoms. For example, they may experience visuospatial dysfunction, primarily manifesting as getting easily lost, even within their own home, unable to find their bedroom. There may also be psychiatric symptoms, such as visual and auditory hallucinations, alongside significant changes in personality and behavior, making nursing care especially important. In caring for dementia patients, it is crucial to prevent the elderly from getting lost by placing a card in their clothing pockets, which should include a phone number and home address to prevent any accidents. Additionally, when elderly individuals are at home alone, it is important to ensure the kitchen door is kept closed to prevent them from entering the kitchen and accidentally turning on the gas stove and forgetting to turn it off, thereby avoiding unnecessary risks. If dementia patients exhibit psychiatric symptoms, it is essential to comfort them, and if necessary, consult a psychiatrist to administer appropriate antipsychotic medications. In the later stages of dementia, patients may become bedridden; at this point, it is important to regularly turn and pat their back to prevent lung infections and provide sufficient nutrition to avoid complications from malnutrition.
How is Parkinson's disease diagnosed?
For the diagnosis of Parkinson's disease, the patient's medical history and symptoms are very important, and physical examinations are also an important reference for diagnosis. The physical examination generally involves checking the patient's muscle tone and looking for signs of bradykinesia. In terms of auxiliary examinations, on one hand, it is necessary to perform ceruloplasmin tests, which primarily aim to exclude hepatolenticular degeneration. Brain MRI scans are also conducted to exclude other causes of secondary Parkinson’s disease, such as normal pressure hydrocephalus and cerebrovascular diseases. Additionally, these patients need to undergo olfactory tests and some PET-CT scans to clarify the diagnosis.
