Migraine With Aura – How To Monitor Migraine Auras

Migraine With Aura – How To Monitor Migraine Auras.
Flashing lights, wavy lines, tingling — for many people who have migraine headaches, these and other sensations, known as an aura, signal that a migraine is about to occur. But while auras can be unnerving, seeing them is like hearing a fire alarm; it’s telling you to take medication right away and possibly stop the migraine before it begins.

Aura: What You Might See

The aura that precedes a migraine can take different forms. You might see:
  • Wavy or jagged lines in a zig-zag pattern.
  • Flashing lights and colors.
  • Blind spots or partial loss of vision.
  • Distortions of the size, shape, and location of fixed objects.
  • Your face might feel numb.
  • Your speech could get slurred.
  • You might feel like you’re about to fall.
  • You feel like pins and needles are moving slowly down your arm.

Migraine Aura: Is it Dangerous?

Some researchers don’t think so. Scientists who have looked at brain images of people experiencing an aura think aura is an electrical phenomenon involving nerves in the brain. Whether one person with migraine has auras and another doesn’t will depend on which patient has the more sensitive nerve cells.
When particularly sensitive nerve cells are repeatedly stimulated by flashing lights, for example, that stimulation builds up over time. So when the nerve cells suddenly begin firing off, they trigger activity that leads to those visual and other disturbances.

Migraine Aura and Risk of Stroke

Migraine aura signs are similar to symptoms that people who have had a transient ischemic attack, or a mini-stroke, feel. A TIA occurs when your blood vessels are temporarily blocked, usually causing no lasting damage.
“This is very disturbing, and many people think they are having a stroke,” says Seymour Diamond, executive chairman of the National Headache Foundation, and director of the Diamond Headache Clinic and the inpatient headache unit at Saint Joseph Hospital in Chicago. The way you tell the difference, Dr. Diamond says, is that with an aura, the feeling will travel down the arm. If the person is having a stroke, the sensation would affect the whole arm, at once.
Research suggests that there may, in fact, be a connection between migraine aura and stroke, especially in women over age 45. And the link between stroke and migraines with visual auras is even stronger in women who smoked and used oral contraceptives.
What’s the connection between stroke and aura? One theory suggests that the aura slows blood flow and increases blood-clotting factors, leading to the potential for blocked blood vessels. While stroke during the actual aura is extremely rare, the blood vessels that become inflamed during the aura can remain that way for some time after the aura passes, creating a greater risk for arterial damage and hardening.
People with visual auras who suffer mild, infrequent attacks are at minimal risk, while those who have suffered severe, lengthy attacks for several years, smoke, or use oral contraceptives are at greatest risk. However, the number of people with visual aura who suffer stroke is still relatively low, and more research is needed before a more definite answer is found about the connection between strokes and auras.

Monitoring Migraine Auras

Some doctors will closely monitor their patients with visual aura who have a long history of severe, lengthy attacks, because of their risk of stroke. K. Michael Welch, MD, president of the Rosalind Franklin University of Medicine and Science in Chicago, says he will prescribe a daily baby aspirin for a patient with severe visual migraine aura — not to ward off migraines, but to reduce the stroke risk.
If you have migraines with aura, don’t be surprised if the aura comes and goes; don’t even be surprised if they appear and a headache doesn’t follow.
What you should pay attention to: An older person who’s never had a migraine and who starts having migraine aura-like symptoms. Make sure that person sees his or her doctor to rule out problems such as TIA and other brain conditions.

What Is Continuous Spike-Wave in Slow Wave Sleep Syndrome? (A RARE EPILEPSY)

Image via Wikipedia Continuous spike-wave in slow wave sleep syndrome (CSWS) is a rare epilepsy syndrome in which children lose a wide range of developmental abilities, including language, motor skills, memory, and visuospatial skills. This syndrome occurs in school-aged children. Development prior to onset of CSWS may be normal, but children with CSWS often have some pre-existing learning difficulties. In many children there is no known cause of epilepsy, although some children are found to have abnormal brain formation or have a prior history of brain infection. We still do not understand how these structural changes result in the continuous EEG discharge.

Many, but not all, children with CSWS also have seizures. There can be many different seizure types, including absence, generalized tonic-clonic, and focal seizures. The seizures can be difficult to treat. Even in those who already had learning difficulties, there is a clear loss of skills across multiple deve…

Vitamin B12: The Most Important Nutrient You Need

Image via Wikipedia
Image by icethim via Flickr If you aren’t getting enough vitamin B12, it is indeed very important – and you may very well not be thinking about it. One reason you aren’t thinking about it is that we tend to fall in (and out!) of love with one nutrient at a time (such as vitamin C, beta carotene, lycopene and so on), and vitamin B12 isn’t the nutrient du jour. But the other reason you may not be thinking about it is … because you can’t. A deficiency of vitamin B12 can limit your ability to think clearly about anything! (More on that momentarily.)
Like all vitamins, B12 is an organic compound, made from carbons (as opposed to minerals, which are inorganic), and essential for our normal metabolic function and health. Also, like most vitamins, B12 plays a wide variety of roles in our metabolism. The short list of important effects B12 has on your health includes these: Vitamin B12 is essential for the manufacture of red blood cells; a deficiency leads to a cha…

Aloe Vera - diabetes, asthma, epilepsy, burns, sunburns, psoriasis and osteoarthritis

Introduction This fact sheet provides basic information about aloe vera—common names, uses, potential side effects, and resources for more information. Aloe vera's use can be traced back 6,000 years to early Egypt, where the plant was depicted on stone carvings. Known as the "plant of immortality," aloe was presented as a burial gift to deceased pharaohs.
What Aloe Vera Is Used ForTraditionally, aloe was used topically to heal wounds and for various skin conditions, and orally as a laxative.Today, in addition to traditional uses, people take aloe orally to treat a variety of conditions, including diabetes, asthma, epilepsy, and osteoarthritis. People use aloe topically for osteoarthritis, burns, sunburns, and psoriasis.Aloe vera gel can be found in hundreds of skin products, including lotions and sunblocks.The Food and Drug Administration (FDA) has approved aloe vera as a natural food flavoring.
