Stroke

What is a stroke?

A stroke occurs when a blood vessel in the brain is blocked or bursts. Without blood and the oxygen it carries, part of the brain starts to die. The part of the body controlled by the damaged area of the brain can't work properly.
Brain damage can begin within minutes, so it is important to know the symptoms of stroke and act fast. Quick treatment can help limit damage to the brain and increase the chance of a full recovery.

What are the symptoms?

Symptoms of a stroke happen quickly. A stroke may cause:



Osteoporosis

What is osteoporosis?

Osteoporosis is a disease that affects your bones. It means you have bones that are thin and brittle, with lots of holes inside them like a sponge. This makes them easy to break. Osteoporosis can lead to broken bones (fractures) in the hip, spine, and wrist. These fractures can be disabling and may make it hard for you to live on your own.
See a picture of healthy bone versus bone weakened by osteoporosis.
Osteoporosis affects millions of older adults. It usually strikes after age 60. It’s most common in women, but men can get it too.

Insomnia

What is insomnia?
 
Insomnia is a common sleep problem that can affect your quality of life. People with insomnia have trouble falling asleep or staying asleep. They may wake up during the night or wake up too early the next morning.
Your sleep problems may come and go, or they may be on going.




  • A short-term sleep problem is often linked to short-term stress. This short-term insomnia can last for days to weeks. It often gets better in less than a month.
  • A chronic sleep problem is ongoing. This is called chronic insomnia. It is often a symptom of another health problem, such as depression or chronic pain. Chronic insomnia is less common than short-term sleep problems.

    What causes insomnia?
    There are many things that can cause sleep problems. Insomnia may be caused by:

    Cold sores

    Cold sores, sometimes called fever blisters, are clusters of small blisters on the lip and outer edge of the mouth. Cold sores are caused by the herpes simplex virus.
    Once a person is infected with the herpes simplex virus, cold sores can occur repeatedly. The sores often weep a clear fluid and form scabs after a few days. A cold sore typically lasts 8 to 10 days and is contagious until the blister is completely crusted over.
    Cold sores usually heal on their own. Medications are available for more rapid healing, reducing pain, and reducing the severity of future outbreaks.

    HIV /AIDS

    Human immunodeficiency virus, or HIV, is a virus that attacks the immune system. Without treatment, HIV can lead to AIDS (acquired immunodeficiency syndrome). People with AIDS have a hard time fighting off infections, which can be potentially life-threatening. There's no cure for HIV, but it can take years—10 or more—for AIDS to develop, even without treatment. And with treatment (there are many types of drugs that fight HIV), people with HIV can remain symptom-free for much longer.

    What is HIV? What is AIDS?

    HIV (human immunodeficiency virus) is a virus that attacks the immune system, the body’s natural defense system. Without a strong immune system, the body has trouble fighting off disease. Both the virus and the infection it causes are called HIV.
    White blood cells are an important part of the immune system. HIV invades and destroys certain white blood cells called CD4+ cells. If too many CD4+ cells are destroyed, the body can no longer defend itself against infection.
    The last stage of HIV infection is AIDS (acquired immunodeficiency syndrome). People with AIDS have a low number of CD4+ cells and get infections or cancers that rarely occur in healthy people. These can be deadly.
    But having HIV does not mean you have AIDS. Even without treatment, it takes a long time for HIV to progress to AIDS—usually 10 to 12 years. If HIV is diagnosed before it becomes AIDS, medicines can slow or stop the damage to the immune system. With treatment, many people with HIV are able to live long and active lives.

    Epilepsy

    What is epilepsy?

    Epilepsy is a common condition that causes repeated seizures. The seizures are caused by bursts of electrical activity in the brain that are not normal. Seizures may cause problems with muscle control, movement, speech, vision, or awareness. They usually don't last very long, but they can be scary. The good news is that treatment usually works to control and reduce seizures.
    Epilepsy is not a type of mental illness or intellectual disability. It generally does not affect how well you think or learn. You can't catch epilepsy from someone else (like a cold), and they can't catch it from you.


    What causes epilepsy?


    Often doctors do not know what causes epilepsy. Less than half of people with epilepsy know why they have it.
    Sometimes another problem, such as a head injury, brain tumor, brain infection, or stroke, causes epilepsy.

    4 Ways to Outsmart the Flu

    Whether or not you get a flu shot, try these tricks to lower your chances of getting grounded by the flu, as well as to prevent colds and other infections.

    Wash, over and over
    Your hands need attention. Use plain old soap and water, and make sure to rub vigorously for 15 to 20 seconds.

    Avoid crowds
    The flu virus thrives on socializing. Do more shopping online than at the mall, and try to cover your face if someone sneezes near you.

    Keep hydrated
    Membranes in your nose and throat trap viruses and move them back out in the form of mucus. Drink lots of fluids and gargle to keep your membranes in fighting shape, says Neil Schachter, MD, author of The Good Doctor’s Guide to Colds and Flu. But avoid humidifiers; they can spread germs.

    Cold, Flu, and Sinus

    You've got a stuffy nose, a sore throat, and a pounding headache, but how do you know if it's a cold or the flu?

    What Ails You: Cold, Flu, or Something Else?

    What's causing my symptoms?

    With flu season in full swing, it’s important to know what ails you (so you can help stop the spread by staying home). But how do you really know if you have the flu—swine or seasonal—or if it’s just another cold or an allergy? Use our handy sympt-o-meter.

    Back Pain

    If you have back pain or neck pain, you have a lot of company. About 8 in 10 people experience back pain at some point in their lives. Back or neck pain often goes away in time—60% of back pain is gone within a week and 95% within 12 weeks. But if your pain persists for three months or more, it’s considered chronic pain, a tricky-to-treat condition that could be due to injury, overuse, arthritis, or spinal problems.

    Back Pain? 7 Questions to Ask Before Surgery

    Tough decisions

    If you have chronic back trouble, choosing surgery can be fraught with tension.

    Unlike with no-brainer operations—such as an appendix removal—there is not a 100% certainty that surgery will cure the problem that’s causing your back pain.

    Anemia

    Anemia is caused by a lack of red blood cells or hemoglobin, the oxygen-carrying protein found in red blood cells. Anemia is most often due to a deficiency in iron, a key component of hemoglobin. (That’s why it is often treated with iron supplements). Anemia can be triggered by blood loss, a folic acid or vitamin B12 deficiency, sickle cell disease, and a genetic disorder called thalassemia, among other causes. In the U.S., 2% to 5% of women and 1% of men have iron deficiency anemia.


    Iron Deficiency Anemia

    What is iron deficiency anemia?
    Iron deficiency anemia occurs when your body doesn't have enough iron.
    Iron is important because it helps you get enough oxygen throughout your body. Your body uses iron to make hemoglobin. Hemoglobin is a part of your red blood cells. Hemoglobin carries oxygen through your body. If you do not have enough iron, your body makes fewer and smaller red blood cells Click here to see an illustration.. Then your body has less hemoglobin, and you cannot get enough oxygen.

    5 Misleading Myths Vaccines

    Although already introduced since the early 20th century, today vaccination coverage in many places not yet reached 100 percent. In fact, the number of children who received the vaccine decreased. In Indonesia the immunization coverage of only about 60 percent.
    In fact, vaccination has proven to be a cheap and effective way to prevent morbidity and mortality in children due to infectious diseases.
    Here are five myths about the vaccine and misleading facts behind the myth.
    1. Vaccines are not important Until now the disease is successfully ELIMINATED (loss) before smallpox pockmarks (small pox). Other diseases, although the vaccine was discovered decades ago, still exist. For example, polio, chicken pox or whooping cough.


    2. The children receive too many vaccines too early and The vaccine is most effective ways to prevent infectious diseases faced by the children of the neighborhood every day.
    "The body of the child continues to face many things that make their immune systems work hard, ranging from bacteria in our own bodies are also bacteria that comes from food, drink and the air," said Paul Offit, director of the Vaccine Education Center Children's Hospital of Philadelphia.
    Experts immunology from the University of California, USA, examined the amount of vaccine that can be responded by a person's body at a time. After considering various types of components in the vaccine, including bacterial proteins, they found that infants and children can safely respond to 100,000 vaccines at one time. Whereas the average a child get 14 kinds of vaccine within two years.
    3. MMR vaccine caused autism This myth began developing in 1998 when Dr.Andrew Wakefield and his team published the findings in the journal The Lancet. They observe the health of 12 children, who 8 of them having a developmental disorder which, according to the children's parents was caused by the MMR vaccine. The study has caused panic around the world and cause the number of children immunized has fallen dramatically.
    And earlier this year the editors of The Lancet officially declare that the research interesting for spreading false information. After lengthy research, experts, including physicians in the WHO said the MMR vaccine is not associated with increased cases of autism in the world.
    Various studies have been conducted and found no link between MMR vaccine with autism. One of the largest and long-term study published in the New England Journal of Medicine in 2002. The study looked at 537,000 health of children and found rates of autism between children who got the vaccine and not turned out the same.
    4. Vaccines are not 100 percent safe This myth may have a point. However, walking was not guarantee we are not 100 percent safe? We could have been dropped or tersenggol motor. In fact it does not make people so afraid to walk on the roadside.
    Most vaccines are given via injection can cause pain, redness and swelling on the skin at the injection. Other side effects were fever and allergic reactions. Even so, the nature of the side effects that individual. Moreover, the risk is greater if the child is not immunized. Vaccine technology became more sophisticated so that the reaction to the vaccine are much less frequent and lighter.
    5. Vaccines prevent disease is not effective Most vaccines currently in circulation are already in the next 50 years, so most parents do not recognize the kinds of diseases can be prevented by immunization.
    For example, before a vaccine is available in 1963, nearly all U.S. children had chicken pox before the age of 15. In that country, this disease each year kills 450 people, mostly children. But after the vaccine was introduced, cases of chickenpox dropped to only 37 in 2004.
    Unfortunately, since 2006, the number of children who had chicken pox increased to 130. According to CDC data, most children are not vaccinated at the request of the patient's own parents.
    The same trend also occurred in Britain where the number of people with chicken pox increased from 56 cases in 1998 to 1324 cases in 2008. The reason is because parents did not want her child vaccines.

    11 Signs of Breast Cancer Risk

    Some people feel the new must check the condition of her breasts when there is an immediate family member affected by breast cancer. Genetic element is allowing a person at risk for breast cancer. However, it was not just that. According to the International Women's Organization, there are other things that make a person at risk for breast cancer. They are:
    1. Have never given birth or not give birth until the age of 30 years. 

    2. During pregnancy, especially during the first pregnancy, ended in abortion. 
    3. Using the contraceptive pill before having a full pregnancy or use contraceptive pills for at least 4 years.

    What is Cancer ?

    Cancer begins when cells in a part of the body start to grow out of control. There are many kinds of cancer, but they all start because of out-of-control growth of abnormal cells.  

    How a normal cell becomes cancer 
    Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person's life, normal cells divide faster to allow the person to grow. After the person becomes an adult, most cells divide only to replace worn-out or dying cells or to repair injuries.
    Because cancer cells continue to grow and divide, they are different from normal cells.

    Understanding the Occurrence of Cancer

    Upon hearing the verdict of cancer, many people seemed to hear the death knell. Cancer is the disease claimed the most superior in age because the abnormal cells that grow out of control can be spread throughout the body and damage the normal cells around them.
    Currently there are at least about 200 types of cancer. However, the characteristics of all cancers are the same, namely the growth and spread of abnormal cells uncontrolled. Why cancer can develop in a person and not on others, it is not yet fully known.
    The researchers speculate, 5-10 percent of cancers may be inherited. That is, the disease is inherited by one generation to the next generation through genes that are not normal. However, in most cases, the cancer develops through a complex series of steps that often include excessive exposure due to carcinogens (cancer causing substances), such as tobacco or the sun.
    Carcinogen believed to cause the formation of free radicals, which can damage the strands of DNA molecules carrying information on how to reproduce.
