Vascular headaches The vascular headache occurs when blood vessels in the head enlar

5、ge and press on nerves, causing pain. The most common vascular headache is the migraine(偏头痛 ). One theory about migraine headaches is that they occur when the blood vessels in the head expand and press on the nerves, causing pain. Another theory is that they result from the blood vessels constrictin

6、g and thus blocking blood flow to parts of the brain; this may cause the visual suffering that often accompany or precede a migraine headache.

7、n personality type compulsive, perfectionist, and very success oriented seems to be more likely to be affected with migraine headaches. Causes A number of physical and emotional factors may contribute to migraine headaches. Migraines may be triggered by a sharp reduction in caffeine intake or by all

8、ergies to certain foods. Emotional stress can also cause migraine headaches, as can drinking alcohol, smoking, or an interruption in routine eating and sleeping habits (all of which may be responsible for “weekend“ headaches suffered by some patients). Cyclical, seasonal, or emotional factors may al

9、so be associated with the tendency to develop migraine headaches. A tendency to develop this type of headache may be inherited. Symptoms The predominant symptom of a migraine headache is a sharp pain on one or both sides of the head. Paleness, sweating, and sensitivity to light may accompany the pai

10、n. A warning sensation may indicate an approaching migraine headache. Before the pain begins, some individuals may see flashing lights or “shooting stars“, hear noises, or have an uncomfortable feeling in the arms or legs. Diagnosis Vascular headaches are diagnosed by a careful review of the circums

11、tances surrounding the headaches as well as by a physical examination to rule out any other disorder that might be causing the symptoms. Elimination tests may be done to identify the exact cause of migraines suffered by people who seem to react to certain foods or changes in eating and sleeping habi

12、ts. In an elimination test, all the substances that are suspected of causing the trouble are eliminated and then reintroduced one at a time to identify the specific cause of the migraine headaches. Treatment Treatment of a migraine already in progress usually consists of a drug therapy program chose

13、n from a variety of painkillers, tranquilizers, and special prescribed medications. Prevention Prevention of migraines is possible with several types of medication. Antidepressant drugs and beta-blockers have been shown to prevent migraines in some patients. These drugs work in the body to block wha

14、t are called the beta effects, one of which is expansion of the blood vessels. While it is not yet known exactly how these drugs provide relief research suggests that they act by preventing the initial constriction of blood vessels that causes migraine.

15、ion headache occurs when muscles of the face, neck, or scalp remain tightened for long periods of time. These muscles are then said to be in spasm(痉挛 ). A tension headache is an example of a muscle contraction headache. Causes A muscle contraction headache usually occurs after a specific event that

16、has caused the muscles to tense. The tension is then translated into physical discomfort in the form of a clenched jaw, aching neck, and tightened muscles of the face and head.

A psychological examination may also be conducted to detect any emotional problems that may be contrib

19、uting to the headaches. Treatment Treatment usually begins with eliminating the tension or correcting the physical problem that is causing the headaches. Painkillers, muscle relaxants, and-tranquilizers may occasionally be used to treat muscle contraction headaches. Also, antidepressant drugs may be

20、 effective in preventing the headaches in those individuals who suffer from them regularly. Inflammatory Headaches An inflammatory headache is caused by pressure within the head, due to any of a variety of disorders. Causes Clogged sinuses(窦 ) and sinus infections are probably the chief cause of thi

21、s type of headache. The sinuses are the cavities within the facial bones.

22、ading to headache. Other causes of inflammatory headaches include a brain tumor.

25、ases the amount of blood in the head. Diagnosis This type of headache is diagnosed by determining first whether sinus problems are causing it. If not,the doctor may order an electroencephalogram(EEG), which is a visual record of electrical activity in the brain; X-ray studies; a computed tomographic

26、(CT) scan, which provides a cross-sectional picture of the brain; or a magnetic resonance imaging(MRI) study, which yields images comparable to those obtained with CT but without the use of X-rays. These tests can detect the presence of a tumor, or other abnormality in: the brain that may be respons

27、ible for causing the headache. Treatment Inflammatory headaches are treated according to their causes those triggered by a sinus infection can be treated with painkillers, antibiotics to fight the infection. Headaches resulting from more serious disorders, such as a brain tumor, will almost certainl

28、y require further evaluation and treatment. Prevention Prevention of these headaches is sometimes possible if the cause is as simple as a sinus infection.
