Washington: Young girls who achieve early puberty may also have a greater likelihood of developing migraine headaches, researchers suggest.
"We know that the percentage of girls and boys who have migraine is fairly the same until the menstruation begins. When the period begins with girls, the prevalence is progressing, but our data suggests that it is already occurring before." said Vincent Martin, one of the study's researchers.
About 10 percent of school children suffer from migraine, a study reported in the American Headache Society found. Because adolescence is approaching, the incidence of migraine is rapidly increased in girls, and by the age of 17, about 8 percent of boys and 23 percent of girls have had migraine.
The girls were between the ages of 8 and 20 and the study took place over a 10-year period starting in 2004. The girls who were included in the study at 8-10 years were examined every six months during the study visit up to 12 months. The researchers found out the initial signs of weight (breast development), pubarche (pubic hair growth) and menarche (onset of menstruation).
The girls responded to the headache questionnaire to determine whether they have a migraine headache, migraine or a likely migraine, the latter being defined as meeting all of the diagnostic criteria for migraine, with the exception of one. The average age at which the survey was conducted was 16 years.
Of the respondents, 85 girls (11 per cent) were diagnosed with migraine headache, and 53 (7 per cent) with migraine, and 623 (82 per cent) with migraine.
The researchers found that girls with migraine had an older age (breast development) and the onset of menarche (menstrual periods) than those without migraine.
On average, breast-feeding occurred four months earlier in those with migraine, while menstruation started five months earlier. In the age of pubarche (pubic hair development) there was no difference between migraine and migraine patients.
"There has been a 25% increase in the possibility of having migraine every year before that the girl has either a hair or a twist. This indicates a strong link between early puberty and the development of migraine in adolescents," said Susan Pinney. head of research.
The age of the occurrence of this pain, puberty or menarche did not differ from those with the likely migraine and migraine, Pinney said.
Previous research has shown that migraine often begins with the onset of menstrual cycles during menarche in adolescents. But this study deals with previous levels of puberty, such as thelar and pubarche, explained Martin.
"It may be suggested that migraine may occur before menstruation, it is quite new. At each of these levels, different hormones occur in the girls, while testosterones and androgens are present during the pub, while the hardest one is the first exposure to estrogen Menarhe when a more mature hormone pattern occurs. Our study suggests that the first estrogen exposure could be the starting point for migraine in some adolescents. .
