Symptoms of Parkinson's Disease

In 1817, James Parkinson used the words "shaking palsy" to describe the symptoms of the disease that was eventually named after him. The TREMORS of the hands, ARMS, legs, JAW and face that he described are perhaps the most obvious symptoms, but as he noticed, they're NOT the only ones. This motor disorder has THREE other primary symptoms: Slowness of movement, known as bradykinesia, stiffness of the limbs and torso, and diminished balance and coordination. And loss of motor function becomes worse over time as nerve cells that produce the neurotransmitter DOPAMINE, which controls movement, gradually degenerate. This slow erosion of muscle control causes people with Parkinson's to experience SECONDARY symptoms such as difficulty speaking, swallowing or chewing, urinary problems, cognitive issues, sleep disruptions, and depression and anxiety.

To treat atrial fibrillation -- an irregular, rapid heartbeat -- your doctor will prescribe medications and lifestyle changes to REGULATE your heart rate and PREVENT blood clots that could cause a stroke or heart attack. In some cases, medical procedures or surgery are also necessary. To slow your heart rate, beta-blockers and calcium channel blockers are often prescribed. They help dilate blood vessels, which takes pressure off the heart and lowers blood pressure. Digoxin is also prescribed to slow your heart rate. It works by regulating electrical impulses that generate the heartbeat. Antiarrhythmic medications such as POTASSIUM channel blockers and sodium channel blockers are also recommended. Sodium channel blockers reduce the heart's ability to conduct electricity, while potassium channel blockers slow down the electrical signals. They both keep erratic electric impulses from making the heart beat sporadically. These medications are initially effective 30 to 60 percent of the time, but may lose their usefulness. And in some cases they can cause more arrhythmia. To prevent or treat existing blood clots, blood thinners, known as anticoagulants and antiplatelets, are recommended. Aspirin, heparin, warfarin, and dabigatran are the most common ones. It is also important to make lifestyle changes that will protect your heart. For instance, quitting smoking, drinking alcohol in moderation - or not at all - and avoiding caffeine may lower blood pressure and increase blood oxygenation. Also, tell your doctor about your use of all over-the counter medications; certain cough and cold medications can aggravate symptoms, as can caffeine-containing migraine medications. Sometimes, when medications and lifestyle changes don't stabilize your heart rhythm, a medical procedure or surgery may be needed.

Although there are 4 different courses of multiple sclerosis, it BEGINS when the immune system MISTAKENLY attacks MYELIN, a protein that forms a protective sheath that covers the end of neurons --nerve cells that transmit messages to the spinal cord and brain. MS is an autoimmune disease - and no one is sure what it is that makes the body destroy its own essential components. But once it begins, it may trigger what is called relapsing-remitting MS, the MOST common course of the disease. About 85 percent of people are INITIALLY diagnosed with this form of the disease. This type of MS features unpredictable, inflammatory attacks that can last for days or weeks. But it then goes into partial or FULL remission for weeks, months or YEARS, only to RETURN once again at some unpredictable future date. Most people with relapsing-remitting MS will go on to develop SECONDARY progressive MS. During this course the symptoms worsen STEADILY over the years as nerve damage increases and spreads. Disease-modifying therapy with biologics, such as beta 1-a, MAY be able to delay the onset of this course or control symptoms. Only around 10 percent of people are initially diagnosed with PRIMARY-progressive MS. Patients with this course START off with a steady worsening of symptoms and nerve damage. Disability will likely get worse over the years, although it may plateau at some point. There are no episodes of suddenly worsening symptoms - sometimes called exacerbations. Progressive relapsing MS is the LEAST common course. It affects about 5% of people with the disease. This type is characterized by a steady progression of nerve damage right from the beginning - and with occasional exacerbations, when symptoms flare up suddenly. Each flare may be different - some triggering only one symptom, some causing multiple problems. No matter the course of disease, some of the many possible symptoms of MS include blurry or double vision, numbness, tingling, imbalance, dizziness, and walking problems.

Patients experience a wide variety of symptoms associated with their migraine headaches, which means that there is no such thing as a "typical" migraine. However, when suffering from migraine headache, people generally are sick to their stomach and often vomit. There are a number of other symptoms that are commonly experienced by migraine sufferers. Migraine headaches typically begin as a dull ache, and progress into a throbbing pain. Typical migraines last roughly 4 to 12 hours, although particularly bad migraines can last as long as a week. When a patient is suffering from a migraine headache, they often are very sensitive to light, sounds, and certain odors; Also, many migraine sufferers have difficulty thinking and feel off balance. If one or more of these symptoms is present, (especially inability to function or nausea) it is likely that the headache sufferer is having a migraine.

Physiologically, an aura is due to changes that take place in the cortex, the outer layer of the brain. When a person begins to develop an aura, it is believed that activity in nerve cells in one part of the cortex become first become excited and then become depressed. With time the change in activity spreads across the cortex, impairing the function of the body parts controlled by these cells.

There are a number of foods that are recognized as headache triggers. One common trigger is alcoholic beverages, especially red wine, which contains tannins. Caffeine withdrawal is also prone to set off headaches, which is why overuse of caffeinated beverages like coffee and soda can trigger a migraine. Also, MSG, a spice found most commonly in Chinese food, can initiate a migraine headache in some patients. Although there is a popular perception that chocolate plays a role in initiating migraine headaches, many experts now believe that chocolate is not actually a migraine trigger. Rather the desire to eat chocolate is a sign of an impending migraine attack. In addition to eating these particular foods, missing a meal can also initiate a headache.

There are actually hundreds of different triggers that patients have reported. Some other frequently reported triggers include intense stress, bright light, cigarette smoke, the scent of perfumes and cleaning products, menstruation, and rapid changes in temperature. It is important to remember that very few of these reported triggers will actually start a headache for any particular person. In fact, most patients have three or fewer triggers, and one very effective way to prevent headaches is to identify these triggers and avoid them.

Sometimes a migraine headache seems to come out of nowhere. But could something actually be setting them off? Although migraine headaches are actually caused by physical changes in the brain, nearly 85% of migraine sufferers report that certain foods or environmental changes can "trigger" a headache. Even though there are a number of commonly recognized triggers, each trigger affects individual patients differently. There are a number of foods that are recognized as headache triggers. One common trigger is alcoholic beverages, especially red wine, which contains tannins. Caffeine withdrawal is also prone to set off headaches, which is why overuse of caffeinated beverages like coffee and soda can trigger a migraine.

Rather the desire to eat chocolate is a sign of an impending migraine attack. In addition to eating these particular foods, missing a meal can also initiate a headache. But food is by no means the only kind of headache trigger. Significant changes in weather, such as an approaching storm front, also commonly precede migraines. There are actually hundreds of different triggers that patients have reported. Some other frequently reported triggers include intense stress, bright light, cigarette smoke, the scent of perfumes and cleaning products, menstruation, and rapid changes in temperature. It is important to remember that very few of these reported triggers will actually start a headache for any particular person. In fact, most patients have three or fewer triggers, and one very effective way to prevent headaches is to identify these triggers and avoid them. If you want to identify what your triggers are, one very useful tool is the headache diary. Frequent headache sufferers should start with a blank notebook, and put the date at the top of each page. Each day you should record the weather, everything you eat, any stressful events, or anything else that seems significant to you, as well as the time, strength, and duration of any headaches. Once you've recorded several headaches, look at the entries you made on those days. Are there items in common? If there are, you may have identified one of your headache triggers. Try to avoid that trigger, and see if that helps reduce your headache frequency. The movies in this series can be viewed in any order. If you wish to watch these clips in their original sequence, then the next clip is, "Stop Your Migraine Before it Stops You: Abortive Medicines," which discusses how certain medications can be used at the onset of headaches to prevent them from developing. The clip recounts the story of how these medications helped a professional football player to remain in the Super Bowl despite getting a migraine during the game.

According to the American Journal of Physiology, your brain represents just two-percent of your body weight, but demands 20-PERCENT of your resting metabolism! In other words, your mind's your body's biggest energy hog, and you have to feed it well if you want it to perform. The best foods for your thinker are known as antioxidants, which include: Vitamin C, Vitamin E, and beta-carotene, a form of Vitamin A. To see how antioxidants work, understand that, like the rest of the body, the brain ages over time. Free radicals, unstable atoms or molecules that occur in the body, are partly to blame. When free radicals meet with oxygen, the result is rust-like oxidative damage to the brain. The good news is that antioxidants REDUCE that damage, keep the brain agile and help slow the aging process. Blueberries, one of the most powerful antioxidants, also reduces the effects of diseases like Alzheimer's and Parkinson's. Prunes, raisins, blackberries, and pomegranates are ripe with good-for-you antioxidants, too. Meanwhile, spinach, Swiss chard, and arugula are vegetables with excellent antioxidant power. Plus, these leafy greens help the body produce happiness hormones, like serotonin and dopamine. When consuming both fruits and veggies, remember: the darker the color, the higher the antioxidant content! Two other brain-boosting sources of antioxidants are probably already a regular part of your diet. I'm talking about coffee and dark chocolate. Aside from slowing down free radical damage, these substances contain caffeine, which enhances short-term memory. Plus, dark chocolate stimulates endorphins, which help improve mood! Just consume in moderation: one ounce of dark chocolate each day is plenty, and you should stop at two to three cups of java or tea. To further boost your brainpower, consume a healthy portion of omega-3 fatty acids. Omega-3s are a primary building block of healthy brain tissue. Find them in coldwater fish like salmon, mackerel, and sardines, and aim for two to three four-ounce servings every week. A good brain diet is basically a healthy body diet. It's easy, natural and tasty, so go ahead and nourish your noggin!

Several areas of the brain are associated with memory. The hippocampus, a librarian of sorts, integrates new information into short-term memory and maintains long-term memories within the cerebral cortex. The amygdala processes memories of emotion. Experts say it takes approximately eight seconds of focused concentration to route information through the hippocampus into the correct memory center. Exercising your brain helps stimulate new pathways among brain cells. Word games and puzzles are good, but challenging yourself with new activities is even better. Learn to play chess, the piano-or read a book about something you know nothing about. The more you challenge your brain to do things new and differently, the better. Take a different route home from work. If you're right-handed, brush your teeth or write with your left hand and vice versa. Physical activity is just as important. It increases blood flow throughout your body-and your brain. 30 minutes of aerobic activity a day, or an equivalent amount of brisk walking, gardening or doing housework, is key. Being active socially is a great way to combine physical and mental challenges, such as golfing, dancing or meeting for a Tai Chi class. Another memory-boosting tip is called "chunking," which involves partitioning large amounts of information into easily digestible bites. For instance, you can remember phone numbers in groups of 3, 3, and 4, or think of your grocery list according to sections of the store. Certain foods may boost your brainpower, too. A recent study looked at wild blueberry juice and found it improved the learning and memory of older adults and feeding your brain with antioxidant-rich vegetables, dark-skinned fruits, cold-water fish and nuts also helped.

People have believed that we use only 10% of our brains for more than 100 years. Unfortunately, all that means is that people have been wrong for MORE than 100 years. This is probably one of the most oft-repeated factoids about the brain, in part because it's been endlessly publicized in the media. Here's the thing, though; it's NOT true. Brain scans show that the vast majority of the brain does NOT lie fallow. For any given activity, like eating, walking, kissing, or reading naughty novels, you use a few specific parts of your brain. So where did the myth come from? Many sources point to an American psychologist from the early1900s, named William James, who said: "the average person rarely achieves but a small portion of his or her potential. "Many sources point to an American psychologist from the early1900s, named William James, who said: "the average person rarely achieves but a small portion of his or her potential." Over the course of a whole day, however, just about ALL of the brain is used at one time or another. You are, in fact, using 100% of your brain.
