  • worsening headache with fever

  • new-onset neurological deficit
  • new-onset cognitive dysfunction
  • change in personality

  • age under 20 years and a history of malignancy

Do not refer people diagnosed with tension-type headache, migraine, cluster headache or medication overuse headache for neuroimaging solely for reassurance.

Consider using a headache diary to aid the diagnosis of primary headaches

If a headache diary is used, ask the person to record the following for a minimum of 8 weeks:

  • frequency, duration and severity of headaches
  • any associated symptoms
  • all prescribed and over the counter medications taken to relieve headaches
  • possible precipitants
  • if female and of having periods - relationship of headaches to menstruation
