The study found 60 percent of the children no longer had chronic daily headache after one year and 75 percent no longer had the symptoms after two years, said a release of the American Academy of Neurology (AAN).

After eight years, only 12 percent of the 103 children tested still experienced symptoms of chronic daily headache. However, 75 percent of the children had episodic migraine or probable migraine, while 11 percent became headache free after eight years.

'Parents and children should be prepared for the possibility that while chronic daily headache may get better over time, headaches in general may never fully go away, but for most children the headaches are much less frequent when they become young adults,' said Wang.

The study was published in the July online issue of Neurology, the journal of the AAN.
