Top 10 Life-Threatening Diseases and Effective Early Prevention Methods

Multiple Sclerosis (MS) is a disease caused by inflammation in the brain or spinal cord, which can damage the brain and spinal components and lead to various symptoms. MS is an autoimmune disease affecting the myelin of the central nervous system. Though the name may sound unfamiliar to many, it is one of the most dangerous diseases today. Severe cases can lead to permanent disability, and there is currently no specific cure for the disease. Patients often experience chronic fatigue, and symptoms worsen with physical activity or hot weather. Urinary or respiratory infections can increase the risk of complications.
Prevention: To prevent MS, it is essential to boost your body’s immunity, treat viral infections thoroughly, exercise regularly, maintain a balanced diet, reduce stress, and ensure personal hygiene...

Parkinson's Disease, also known as shaking palsy, is a neurodegenerative disorder caused by the degeneration of dopamine-producing neurons in the brain. This results in a decline in dopamine levels, which is essential for controlling muscle movements. The disease progresses gradually, making it difficult to detect in its early stages. Initially, symptoms may not be obvious, but as the disease advances, individuals may experience hand tremors, muscle rigidity, stiffness, and slowness of movement, making daily activities challenging. Parkinson's typically begins in individuals over 60, although about 1 in 10 people develop it before 50, and it is very rare for someone to be diagnosed under 30.

In the early stages, common symptoms of Parkinson's disease include fatigue, muscle pain, clumsiness with simple actions such as putting on socks or shoes, small handwriting, constipation, depression, dragging one leg, or decreased arm movement while walking. Sometimes, tremors at rest can be subtle and occur intermittently.

The classic symptoms of Parkinson's disease are:

• Tremors: These often begin in one side of the body and are noticeable in the hands, face, or tongue. Tremors may stop temporarily with movement, but return afterward. They are absent during sleep, and stress can increase tremors. In some cases, tremors may not appear at all.
• Rigidity: Muscle stiffness is one of the most significant symptoms, affecting all muscle groups and making movement difficult. Muscles feel tight and rigid when touched.
• Bradykinesia (slowness of movement): A reduction in spontaneous movements, especially in facial expressions and the arms and legs. The face may appear mask-like, with fewer facial expressions and blinking.

Prevention: It is important to adopt healthy habits early in life to reduce the risk of Parkinson's. Regular physical activity, a balanced diet, and proper work-life balance can help. Additionally, spending time in the sun, drinking green tea, consuming antioxidant-rich fruits like berries, and avoiding environments with pollution and smoke are all helpful for prevention.

Alzheimer's Disease is one of the most common causes of memory loss in older adults. It is characterized by the gradual degeneration of neurons and synapses in the brain's cortex and some subcortical regions. The condition typically worsens over time, severely impacting daily activities, memory, language, and cognitive function. Alzheimer's commonly affects individuals over the age of 65, but early-onset Alzheimer's, though rare, can develop between the ages of 50 and 65, accounting for about 4-5% of cases.

Alzheimer's Disease progresses through distinct stages, with each stage presenting different symptoms. It causes overall brain degeneration that is irreversible. The brain's neurons and surrounding structures gradually become damaged, reducing the ability to coordinate movement, causing sensory disturbances, and ultimately leading to memory loss.

Prevention: To reduce the risk of Alzheimer's, it is essential to maintain a balanced lifestyle, manage stress, avoid excessive stimulants, and engage in activities that promote brain health, such as memory-enhancing supplements and cognitive exercises.

Stroke, also known as a cerebrovascular accident (CVA), occurs when there is a severe disruption or reduction in blood flow to the brain, leading to oxygen deprivation and insufficient nutrients for brain cells. Without immediate intervention, brain cells begin to die within minutes. A stroke requires urgent medical attention; the longer the delay in treatment, the greater the damage to brain cells, which can impair motor skills and cognitive function, and in severe cases, result in death. Survivors of a stroke often suffer from long-term health complications such as partial paralysis, speech loss, emotional disorders, and impaired vision. Stroke patients face significant challenges in daily life and are at risk of sudden collapse, lifelong disability, or even death from further shocks.

Prevention: Regular exercise, avoiding tobacco, alcohol, and other stimulants, along with a healthy diet rich in vegetables, fruits, chicken, and fish, while limiting red meat, are key steps to prevent stroke. Proper management of cardiovascular and endocrine diseases such as hypertension, arrhythmias, and heart valve disorders is also crucial.

Liver failure is a common condition that threatens the lives of many people and requires prompt treatment. Common causes of liver failure include chronic hepatitis B and C infections, alcohol abuse leading to cirrhosis, and fatty liver disease. Nutritional deficiencies can also impair liver function, making the liver vulnerable to failure. If left untreated, liver failure can progress to liver cancer, which is often incurable.

Liver failure can be categorized into two types: acute and chronic. Acute liver failure can develop suddenly without warning signs, and the liver's function can deteriorate within days or weeks. Chronic liver failure, often a consequence of cirrhosis, progresses more slowly, with symptoms sometimes taking months or even years to appear.

Prevention: To prevent liver disease, get vaccinated against hepatitis B, maintain a balanced diet, practice good hygiene, and avoid exposure to individuals infected with hepatitis B or C. Regular health check-ups, including liver function tests every six months, are essential for early detection and prevention.

Systemic lupus erythematosus (SLE) is a type of autoimmune disease, often divided into discoid lupus and systemic lupus. SLE occurs when the immune system mistakenly attacks the body's own tissues and organs, causing inflammation and tissue damage. Though there is no definitive cure for lupus, it can be managed effectively if treatment is started early. Studies show that 90% of lupus patients are women, typically between the ages of 15 and 50, and it affects approximately 50 per 100,000 people.

Systemic lupus erythematosus primarily targets connective tissue, and it can cause severe damage to the heart, joints, skin, lungs, blood vessels, liver, kidneys, and the nervous system. Treatment options include corticosteroids and immune-suppressing medications, but currently, there is no permanent cure for the disease.

Prevention: To boost the immune system, maintain a balanced diet, practice good personal hygiene, and avoid exposure to pollutants and toxins. If symptoms such as fatigue, joint pain, rashes, fever, abdominal pain, headaches, and dizziness arise, consult a doctor immediately for early detection and timely treatment.

Traumatic brain injury (TBI) refers to damage to the skull and internal brain structures caused by impact or trauma to the head. It is a leading cause of death and disability, often resulting in severe long-term effects. TBI is especially dangerous for children and remains a significant concern. The risk of brain injury is common worldwide, particularly in industrialized and developing nations, where increased population density, rapid urbanization, and high-speed transportation contribute to accidents. TBI is a major cause of death, leaving many survivors with permanent disabilities. Among the most concerning cases are brain injuries in children, which pose a substantial challenge for healthcare professionals.

Brain injuries are classified into open and closed types. A closed brain injury occurs when there is damage to the skull but no tear in the meninges, meaning the brain remains sealed off from the outside environment. It may involve skull fractures, brain contusions, swelling, and brain hemorrhage. An open brain injury occurs when there is a tear in the meninges, exposing the brain to external elements, significantly increasing the risk of infection. Other classifications include the type of brain damage and the affected area of the brain.

Prevention: Traumatic brain injury can happen to anyone through accidents such as traffic collisions, household accidents, or workplace injuries. To minimize the risk, it is essential to follow traffic safety laws, adhere to workplace safety regulations, and wear appropriate protective gear such as helmets and safety caps.

HIV is the virus responsible for causing immune deficiency in humans. AIDS represents the final stage of an HIV infection, manifesting through a variety of symptoms. HIV/AIDS is a global epidemic that has claimed millions of lives, and despite extensive research, a cure remains elusive. However, recent breakthroughs have led to the development of ARV (antiretroviral) drugs, which have been proven to extend the lives of HIV-infected individuals. These drugs slow the progression of the virus, offering a ray of hope for patients worldwide, even though they do not cure the disease. ARV medications have become a lifeline for countless individuals living with HIV.

Prevention: HIV/AIDS is transmitted through three primary routes: blood, sexual contact, and from mother to child. To minimize the risk of infection, safe blood transfusions must be ensured, drug abuse and sex work must be addressed, and unprotected sexual activity should be avoided. Additionally, HIV-positive parents should follow strict medical advice if they wish to have children, and mothers who contract HIV during pregnancy should avoid breastfeeding their infants.

According to the International Agency for Research on Cancer (IARC), in 2019, there were 18.08 million new cases of cancer worldwide, with over 9.5 million deaths attributed to the disease. In Vietnam, it is estimated that there were 164,671 new cancer cases, and 114,871 deaths. Common cancers among men include liver cancer (21.5%), lung cancer (18.4%), stomach cancer (12.3%), colorectal cancer (8.4%), and nasopharyngeal cancer (5%). For women, the most common types are breast cancer (20.6%), colorectal cancer (9.6%), lung cancer (9.4%), stomach cancer (8.6%), and liver cancer (7.8%). The age-standardized cancer incidence rate for both genders is 151.4 per 100,000 people, with a mortality rate of 104.4 per 100,000. In Vietnam, approximately 70% of cancer patients are diagnosed at advanced stages (III or IV), even for cancers that could potentially be detected early through screening.

Despite advancements in medical research and ongoing studies to find a cure, there is currently no effective treatment for cancer, which has claimed millions of lives throughout history. Most people discover their illness when it's already at an advanced stage, making treatment much more challenging. Therefore, prevention is better than cure. Everyone should be aware of cancer prevention methods to maintain good health.

Prevention: Regular cancer screenings are essential. Avoid stimulants such as tobacco, alcohol, and other alcoholic beverages. Increase your intake of foods that help prevent cancer, like leafy vegetables, garlic, and tomatoes. Avoid consuming harmful foods like processed meats, moldy food, and canned goods.

Polio (Poliomyelitis) is a viral infection transmitted through the digestive system caused by the Polio virus. It can spread in the form of an outbreak. The disease is identified by symptoms of acute flaccid paralysis. Once the Polio virus enters the body, it travels to the lymph nodes, where some of the virus infiltrates the central nervous system, leading to damage to the anterior horn cells in the spinal cord and the motor neurons in the brain.

Polio is an infectious disease caused by the poliovirus, which spreads through respiratory and digestive routes. Initially, it causes peripheral flaccid paralysis without sensory disturbance. If left untreated, it can develop into an outbreak, especially in crowded places like nurseries and kindergartens. Polio typically peaks at the end of spring and the beginning of summer. It primarily affects children and is highly contagious from person to person.

Prevention: The most effective preventive measure is vaccination. The oral polio vaccine (OPV) is administered to children at 2, 3, and 4 months of age as part of the expanded immunization program. Additionally, the injectable polio vaccine (IPV), which is safer, has been approved by the Ministry of Health for a single dose for children under 1 year, gradually replacing OPV in the national vaccination schedule. Moreover, ensure children consume properly cooked food, drink clean water, and wash their hands thoroughly before meals and after using the restroom.
