The vast majority of patients have primary headaches such as migraine,
tension-type headache, and less commonly, cluster headache. However, secondary
headaches account for around 10% of headaches presented in primarycare.
Secondary headache is common in patients with systemic infections and may also
occur in association with head injury, vascular disorders or overuse of various
drugs.
The most common causes of secondary headache are fasting (19%) and nasal/sinus disorders (15%), with only a small minority due to a more sinister condition such as non-vascular intracranial disease (including tumour). [15]
Warning signs of secondary headache include:
Almost all headaches that are encountered in primary care are primary headaches, and it is very rare that they are the result of a more serious condition. [16] Nevertheless, physicians mayhavevery real concerns about the presence of an underlying sinister diseaseinthose patients who present with headache for the first time. The Headache Care for Practising Clinicians guidelines provide a proposed algorithm for the exclusion of sinister headache in primary care. [16] If sinister headache is suspected,a full neurological examination is essential.
