Headache - assessment

This guideline is recommended for the radiological investigation of patients presenting with headache.

CT is generally not indicated in suspected meningitis unless there are clinical signs which predict for abnormal radiological findings, such as: 

• age >60 years
• immunocompromised
• history of CNS disorder
• associated new onset seizures
• mental state changes
• focal neurological deficits.

If CT is required, blood cultures and antibiotics should not be delayed
