Discussion of underlying conditions of Headache:

Headache - Hope Through Research: NINDS (Excerpt)

Repeated exposure to nitrite compounds can result in a dull, pounding headache that may be accompanied by a flushed face. Nitrite, which dilates blood vessels, is found in such products as heart medicine and dynamite, but is also used as a chemical to preserve meat. Hot dogs and other processed meats containing sodium nitrite can cause headaches.

Eating foods prepared with monosodium glutamate (MSG) can result in headache. Soy sauce, meat tenderizer, and a variety of packaged foods contain this chemical which is touted as a flavor enhancer.

Headache can also result from exposure to poisons, even common household varieties like insecticides, carbon tetrachloride, and lead. Children who ingest flakes of lead paint may develop headaches. So may anyone who has contact with lead batteries or lead-glazed pottery.

Artists and industrial workers may experience headaches after exposure to materials that contain chemical solvents. These solvents, like benzene, are found in turpentine, spray adhesives, rubber cement, and inks.

Drugs such as amphetamines can cause headaches as a side effect. Another type of drug-related headache occurs during withdrawal from long-term therapy with the antimigraine drug ergotamine tartrate.

Jokes are often made about alcohol hangovers but the headache associated with "the morning after" is no laughing matter. Fortunately, there are several suggested treatments for the pain. The hangover headache may also be reduced by taking honey, which speeds alcohol metabolism, or caffeine, a constrictor of dilated arteries. Caffeine, however, can cause headaches as well as cure them. Heavy coffee drinkers often get headaches when they try to break the caffeine habit.

Headache - Hope Through Research: NINDS (Excerpt)

Like other types of pain, headaches can serve as warning signals of more serious disorders. This is particularly true for headaches caused by traction or inflammation.

Traction headaches can occur if the pain-sensitive parts of the head are pulled, stretched, or displaced, as, for example, when eye muscles are tensed to compensate for eyestrain. Headaches caused by inflammation include those related to meningitis as well as those resulting from diseases of the sinuses, spine, neck, ears, and teeth. Ear and tooth infections and glaucoma can cause headaches. In oral and dental disorders, headache is experienced as pain in the entire head, including the face. These headaches are treated by curing the underlying problem. This may involve surgery, antibiotics, or other drugs.

Characteristics of the various types of more serious traction and inflammatory headaches vary by disorder:

  • Brain tumor. Brain tumors are diagnosed in about 11,000 people every year. As they grow, these tumors sometimes cause headache by pushing on the outer layer of nerve tissue that covers the brain or by pressing against pain-sensitive blood vessel walls. Headache resulting from a brain tumor may be periodic or continuous. Typically, it feels like a strong pressure is being applied to the head. The pain is relieved when the tumor is treated by surgery, radiation, or chemotherapy.
  • Stroke. Headache may accompany several conditions that can lead to stroke, including hypertension or high blood pressure, arteriosclerosis, and heart disease. Headaches are also associated with completed stroke, when brain cells die from lack of sufficient oxygen.

Many stroke-related headaches can be prevented by careful management of the patient's condition through diet, exercise, and medication.

Mild to moderate headaches are associated with transient ischemic attacks (TIA's), sometimes called "mini-strokes,"which result from a temporary lack of blood supply to the brain. The head pain occurs near the clot or lesion that blocks blood flow. The similarity between migraine and symptoms of TIA can cause problems in diagnosis. The rare person under age 40 who suffers a TIA may be misdiagnosed as having migraine; similarly, TIA-prone older patients who suffer migraine may be misdiagnosed as having stroke-related headaches.

  • Spinal tap. About one-fourth of the people who undergo a lumbar puncture or spinal tap develop a headache. Many scientists believe these headaches result from leakage of the cerebrospinal fluid that flows through pain-sensitive membranes around the brain and down to the spinal cord. The fluid, they suggest, drains through the tiny hole created by the spinal tap needle, causing the membranes to rub painfully against the bony skull. Since headache pain occurs only when the patient stands up, the "cure" is to remain lying down until the headache runs its course—anywhere from a few hours to several days.
  • Head trauma. Headaches may develop after a blow to the head, either immediately or months later. There is little relationship between the severity of the trauma and the intensity of headache pain. In most cases, the cause of the headache is not known. Occasionally the cause is ruptured blood vessels which result in an accumulation of blood called a hematoma. This mass of blood can displace brain tissue and cause headaches as well as weakness, confusion, memory loss, and seizures. Hematomas can be drained to produce rapid relief of symptoms.
  • Temporal arteritis. Arteritis, an inflammation of certain arteries in the head, primarily affects people over age 50. Symptoms include throbbing headache, fever, and loss of appetite. Some patients experience blurring or loss of vision. Prompt treatment with corticosteroid drugs helps to relieve symptoms.

Meningitis and encphalitis headaches are caused by infections of meninges-the brain's outer covering-and in encephalitis, inflammation of the brain itself.

  • Trigeminal neuralgia. Trigeminal neuralgia, or tic douloureux, results from a disorder of the trigeminal nerve. This nerve supplies the face, teeth, mouth, and nasal cavity with feeling and also enables the mouth muscles to chew. Symptoms are headache and intense facial pain that comes in short, excruciating jabs set off by the slightest touch to or movement of trigger points in the face or mouth. People with trigeminal neuralgia often fear brushing their teeth or chewing on the side of the mouth that is affected. Many trigeminal neuralgia patients are controlled with drugs, including carbamazepine. Patients who do not respond to drugs may be helped by surgery on the trigeminal nerve.
  • Sinus infection. In a condition called acute sinusitis, a viral or bacterial infection of the upper respiratory tract spreads to the membrane which lines the sinus cavities. When one or more of these cavities are filled with fluid from the inflammation, they become painful. Treatment of acute sinusitis includes antibiotics, analgesics, and decongestants. Chronic sinusitis may be caused by an allergy to such irritants as dust, ragweed, animal hair, and smoke. Research scientists disagree about whether chronic sinusitis triggers headache.

Headache - Hope Through Research: NINDS (Excerpt)

Childhood headache can be a sign of depression. Parents should alert the family pediatrician if a child develops headaches along with other symptoms such as a change in mood or sleep habits. Antidepressant medication and psychotherapy are effective treatments for childhood depression and related headache. (Source: excerpt from Headache - Hope Through Research: NINDS)

About underlying conditions:

With a diagnosis of Headache, it is important to consider whether there is an underlying condition causing Headache. These are other medical conditions that may possibly cause Headache. For general information on this form of misdiagnosis, see Underlying Condition Misdiagnosis or Overview of Misdiagnosis.
