Introduction
Under normal circumstances, the main causes of Parkinson's disease include aging, genetic factors, long-term exposure to toxic substances, post-traumatic sequelae of brain injuries, and cerebrovascular diseases. If symptoms such as limb tremors or movement retardation occur, it is recommended to seek timely diagnosis and treatment at a reputable hospital. In daily life, it is important to maintain a balanced diet and consume more vegetables and fruits rich in antioxidants.

Under normal circumstances, the main causes of Parkinson's disease include aging, genetic factors, long-term exposure to toxic substances, post-traumatic brain injury sequelae, cerebrovascular diseases, and others. If symptoms such as limb tremors or movement slowness occur, it is recommended to seek timely diagnosis and treatment at a regular hospital. Detailed analysis is as follows:

1. Aging

With aging, dopamine-producing neurons in the brain gradually degenerate and decrease, leading to insufficient dopamine secretion and triggering Parkinson's symptoms. It is important to maintain moderate exercise in daily life, such as walking and Tai Chi, to delay nerve degeneration, and maintain regular作息 (作息 means rest and work patterns) to avoid excessive fatigue.

2. Genetic Factors

Some Parkinson's patients have a familial genetic tendency, and specific gene mutations may increase the risk of developing the disease. Individuals with a family history should pay attention to physical changes earlier, undergo regular neurological examinations, and aim for early detection and early intervention.

3. Long-term Exposure to Toxic Substances

Prolonged exposure to toxic substances such as pesticides and heavy metals can damage the central nervous system, destroy dopamine-producing neurons, and increase the risk of developing Parkinson's disease. Avoid long-term contact with toxic substances and take proper protective measures at work; if exposure has already occurred, regular physical examinations and monitoring of nervous system function are necessary.

4. Post-Traumatic Brain Injury Sequelae

Severe traumatic brain injury may damage dopamine-producing neurons in the brain, affecting dopamine secretion and triggering Parkinson's symptoms. It is important to maintain safety in daily life and avoid head injuries; if brain injury occurs, timely and appropriate treatment is necessary to reduce the occurrence of sequelae.

5. Multiple Cerebral Infarctions

Multiple cerebral infarctions can affect cerebral blood circulation, causing ischemia and hypoxia damage to dopamine-producing neurons, leading to Parkinsonism. Under a doctor's guidance, medications such as aspirin enteric-coated tablets, clopidogrel bisulfate tablets, and atorvastatin calcium tablets can be used to prevent cerebrovascular disease and improve cerebral circulation.

In daily life, it is important to maintain a balanced diet, consuming more vegetables and fruits rich in antioxidants; maintain a positive and optimistic mindset, avoiding long-term mental stress; engage in appropriate mental activities such as reading and playing chess to exercise brain function; and undergo regular medical check-ups to detect and address any physical abnormalities promptly.

In general, patients with anemia can choose to visit the hematology department, gastroenterology department, gynecology department, nephrology department, or endocrinology department based on specific symptoms and possible causes. Additionally, if anemia is accompanied by symptoms such as dizziness, palpitations, and fatigue with unclear etiology, patients may first go to a general practice clinic for initial screening, then be referred to the appropriate specialist according to the test results.

What diseases can cause thrombocytopenia?
In general, diseases that commonly cause thrombocytopenia include immune thrombocytopenia, aplastic anemia, hypersplenism, hyperthyroidism, and systemic lupus erythematosus. If abnormal platelet counts are detected, it is recommended to seek timely medical evaluation at a正规 hospital. In daily life, avoid taking medications that may affect platelets, such as enteric-coated aspirin.

What causes a bitter taste in the mouth?
Bitter taste in the mouth may be caused by factors such as imbalance of the oral environment, emotional and neurological regulation, gastrointestinal motility disorders, abnormal liver and gallbladder metabolism, or medication effects. It is recommended to maintain a daily water intake of more than 1500 ml, consume moderate amounts of hawthorn and dried tangerine peel to aid digestion, and avoid smoking and limit alcohol consumption. If bitter taste persists for over a week or is accompanied by abdominal pain, jaundice, or significant weight loss, you should visit a gastroenterology or dental clinic for further evaluation, including gastroscopy.

Can cholecystitis cause diarrhea?
In general, whether cholecystitis causes diarrhea depends on the stage of the disease and the status of digestive function. Diarrhea may occur during acute episodes or when chronic cholecystitis affects bile secretion and excretion. However, when the condition is stable, bile secretion and excretion are normal, and digestive function is unaffected, diarrhea usually does not occur. It is recommended to seek medical attention promptly for proper evaluation by a physician.

Do all liver cancer patients have hepatitis?
In general, not all liver cancers are associated with hepatitis. Some liver cancer patients have a history of hepatitis, while others do not have any hepatitis-related issues; the specific situation should be determined based on the causes of liver cancer. It is important to maintain liver health in daily life. Individuals with a history of hepatitis should follow medical advice for standardized treatment and undergo regular check-ups of liver function and liver ultrasound. Those without hepatitis should avoid alcohol consumption, control body weight, and refrain from eating moldy food.

Can liver cancer cause cirrhosis?
In general, whether liver cancer causes cirrhosis depends on the specific medical condition. In most cases, liver cancer itself does not directly cause cirrhosis; however, certain types of liver cancer that share common causative factors with cirrhosis or damage liver structure may be associated with cirrhosis. To prevent both liver cancer and cirrhosis, it is important to avoid long-term alcohol consumption, staying up late, and other liver-damaging behaviors in daily life, and to undergo regular liver examinations.
