For the study, 24,000 people with headaches in the United States were surveyed about the types of medications they use to treat their headaches. From this sample of people with headache, the researchers selected those who had been diagnosed in 2005 with episodic migraine (fewer than 15 days of headache per month). Their risk of chronic migraine was then calculated based on the types of medications they used in 2005. Among those with episodic migraine in 2005, 209 people had developed chronic migraine in 2006.
The study found people who took drugs containing barbiturates or opioids for only eight days a month were twice as likely to develop chronic migraine a year later as those who didn’t take such drugs. “People who use drugs that contain barbiturates and opioids, if only for a total of seven to eight days a month, appear to significantly increase their risk of migraine progression,” said study author Marcelo Bigal, MD, PhD, with Albert Einstein College of Medicine in Bronx, New York. “Strict limits for these types of drugs should be enforced among people with migraine as a way of preventing their migraines from becoming more frequent and more painful.”
The study found no evidence that the risk of developing chronic migraine increased among people who frequently used triptans, which are commonly prescribed drugs to treat migraine, or non-steroidal antiinflammatory drugs (NSAIDs), such as aspirin, ibuprofen and naproxen.
The study was supported by the National Headache Foundation.
The American Academy of Neurology, an association of more than 21,000 neurologists and neuroscience professionals, is dedicated to improving patient care through education and research. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer’s disease, epilepsy, multiple sclerosis, Parkinson’s disease, and stroke.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
