Migraine incidence

Prevalence rates for a variety of different types of pain have been described. The annual incidence of moderate-intensity back pain is 10% to 15% in the adult population with a point prevalence of 15% to 30%.3 Migraine affects more than 25 million Americans, and 90% of Americans report some other types of headaches (e.g., tension or sinus) each year.4 Pain resulting from fibromyalgia affects 4 million Americans.5 Cancer is commonly associated with both acute and chronic pain, and about 70% of those diagnosed with cancer will experience significant pain.6... 

ELETRIPTAN Individualize dose. Single doses of 20 and 40 mg were effective for the acute treatment of migraine in adults, with a greater proportion of patients having a response following a 40 mg dose. Individuals may vary in response to doses of eletriptan tablets. An 80 mg dose, although also effective, was associated with an increased incidence of adverse events. Therefore, the maximum recommended single dose is 40 mg. 

A 0.5% incidence of migraines has been reported among users of oral contraceptives. Migraine headaches may be a warning signal for an oncoming stroke, and immediate discontinuation of oral contraceptive use is recommended. 

Migraine Effective in reducing migraine episodes due to blockade of catecholamine induced vasodilatation in the brain vasculature. Propranolol decreases the incidence and severity of the attack. 

It has become recognized that PFO device closure not only significantly decreases the incidence of paradoxical embolism (47), but can also reduce the incidence of migraine in susceptible patients. Fifty-five percent of patients with aura and 62% of those without aura experienced a reduction of... 

Communities near pulp mills Inhalation Mean annual total reduced sulfur concentrations 2-3 pg/ m 24-b average concentration 0-56 pg/ rtP, maximum 1-h concentration 155 pg/ m1 Daily Reported increased incidence of respiratory system symptoms (irritation, cough) and CNS symptoms (headache and migraine) significant increase only for headache and migraine. Communities exposed to relatively high concentrations of other malodorous sulfur compounds. Partti-Pellinin et al. 1996 (South Karelia Air Pollution Study)... 

Q3 Migraine affects approximately 10% of the population the incidence is higher (double) in women compared to men. The first attack may occur at any time between childhood and early adulthood. Approximately 20% of women in their early forties suffer from migraine.

These are thus measures of incidence. The proportion of a population that will experience at least one seizure or one migraine attack in their lives is a measure of incidence and would likely be expressed as a number per thousand (or per hundred thousand) person-years, whereas the proportion of a population suffering from epilepsy or migraine during the year 2000 is an expression of prevalence. 

Migraine is suffered by about 15% of the population overall, with a female male ratio of incidence of 3 1. Migraine mainly affects younger people 80% of sufferers have their first attack before the age of 30, and incidence is rare after... 

Quinestrol should be administered cautiously to patients with disorders that may be aggravated by fluid and electrolyte accumulation, such as asthma, seizure disorders, migraine, or cardiac, renal, or hepatic dysfunction. Carefully monitor female patients who have breast nodules, fibrocystic breast disease, or a family history of breast cancer. Because of the risk of thromboembohsm, therapy with this drug should be discontinued at least one week before elective surgical procedures associated with an increased incidence of thromboembolism. 

In 40 selected patients, age range 18-64 years, who were randomized in an open study for migraine prophylaxis to topiramate 25, 50, 75 or 100 mg as an evening dose paresthesia was by far the most common adverse reaction (55% of patients) and the incidence was dose related [280. Fatigue, giddiness, diarrhea, nausea, and drowsiness were reported in a few patients, but there was no apparent dose-effect relation.
