    • Alzheimer disease - Animation

    Imagine waking up this morning, and not being able to remember your own name, or recognize your spouse? While Alzheimer disease is a more gradual process, over time it can destroy memory to the point where people can't even remember the simplest and most important details of their lives. Let's talk more about Alzheimer disease. Alzheimer disease is a type of dementia, a loss of brain function that makes it harder and harder to think and speak. To understand what causes Alzheimer, we need to look inside the brain. In a normal brain, nerves send messages to one another. In people with Alzheimer disease, abnormal proteins clump in the brain, damaging nerve cells so they can no longer send the messages needed to think clearly. So, why do some people get Alzheimer, and others do not?Getting older itself doesn't cause Alzheimer disease. It's not a part of the normal aging process. Alzheimer does seem to run in families, though. So if you have a close relative, like a sister or parent, with Alzheimer, you may be more likely to get the disease. Usually when Alzheimer disease starts, people have trouble remembering simple things, like their phone number, or where they put their car keys. But, as the disease progresses, memory loss gets worse. People with Alzheimer find it hard to have conversations or complete simple tasks, like getting dressed. They can also become angry or depressed. Those in the later stages of the disease can no longer care for themselves. They lose the ability to recognize even close family members. To diagnose Alzheimer disease, doctors prescribe tests of mental ability. They also prescribe medical tests to rule out diseases that can make it harder to think clearly, such as a brain tumor or stroke. As far as treatments for Alzheimer disease, right now, there isn't a cure. A few drugs can slow memory loss and control depression and aggressiveness from the disease. Despite what you may have read, there isn't any proof that vitamins or other supplements can prevent or treat Alzheimer. However, eating a low-fat diet that's high in vitamin E and C, and rich in omega-3 fatty acids may keep your brain healthier. Alzheimer disease is different in each person. Some people decline quickly and die within just a few years, while others can live for two decades with the disease. If you have a family member with Alzheimer, talk to your doctor about ways to protect your own memory. And, call right away if you have any significant memory loss. Though it may be normal forgetfulness that comes with getting older, the sooner you get it checked out, the earlier you can start treatment if you need it.

  • Copper urine test

    Copper urine test

    The copper urine test is performed by collecting urine at specific times for a 24-hour period. The urine is tested for the amount of copper present. The copper urine test is used to determine the presence of Wilson disease, a sometimes fatal condition in which the buildup of excess copper damages the liver, and eventually the kidneys, eyes, and brain.

  • Lyme disease

    Lyme disease

    Lyme disease is an acute inflammatory disease characterized by skin changes, joint inflammation and symptoms similar to the flu that is caused by the bacterium Borrelia burgdorferi. Lyme disease is transmitted by the bite of a deer tick. Symptoms sometimes improve in 3 to 4 weeks, but secondary or tertiary disease may develop if initial infection is not treated.

    Tertiary lyme disease

    Tertiary Lyme disease is a late, persistent inflammatory disease characterized by skin changes, neurological and musculoskeletal symptoms caused by the bacterium Borrelia burgdorferi transmitted by the bite of a tick. Tertiary Lyme disease is indicated by chronic arthritis.

    Legionnaire disease was first described in 1976 after an outbreak of fatal pneumonia at a Legionnaires convention. The newly described organism which caused the disease was named Legionella pneumophila, shown in this picture. (Image courtesy of the Centers for Disease Control and Prevention. )

    Crohn disease - affected areas

    The inflammation of Crohn disease is nearly always found in the ileocecal region. The ileocecal region consists of the last few inches of the small intestine (the ileum), which moves digesting food to the beginning portion of the large intestine (the cecum). However, Crohn disease can occur anywhere along the digestive tract.

  • Substantia nigra and Parkinson disease

    Substantia nigra and Parkinson disease

    Parkinson disease is a slowly progressive disorder that affects movement, muscle control, and balance. Part of the disease process develops as cells are destroyed in certain parts of the brain stem, particularly the crescent-shaped cell mass known as the substantia nigra. Nerve cells in the substantia nigra send out fibers to tissue located in both sides of the brain. There the cells release essential neurotransmitters that help control movement and coordination.

    Crohn disease - X-ray

    This lower abdominal x-ray shows narrowing (stenosis) of the end of the small intestine (ileum), caused by Crohn disease. Crohn disease typically affects the small intestine, whereas ulcerative colitis typically affects the large intestine. A solution containing a dye (barium), was swallowed by the patient. When it passed into the small intestines, this x-ray was taken (lower GI series).

    Cat scratch disease

    Cat scratch disease is an infectious illness associated with cat scratches, bites, or exposure to cat saliva, causing chronic swelling of the lymph nodes. Cat scratch disease is possibly the most common cause of chronic lymph node swelling in children.

  • Creutzfeldt-Jakob disease

    Creutzfeldt-Jakob disease

    Creutzfeldt-Jakob disease is an organic brain syndrome caused by a protein-like particle called a prion. Loss of brain function resembles Alzheimer's disease, but is very rapid in progression. Complete dementia usually occurs by the sixth month, death follows quickly. There is no known cure.

  • Inflammatory bowel disease

    Inflammatory bowel disease

    Crohn disease, also called regional enteritis, is a chronic inflammation of the intestines which is usually confined to the terminal portion of the small intestine, the ileum. Ulcerative colitis is a similar inflammation of the colon, or large intestine. These and other IBDs (inflammatory bowel disease) have been linked with an increased risk of colorectal cancer.
