Headache can be either a late or early symptom of a brain tumour, depending on the location of the tumour. A constant, progressively increasing pain, or a change in the character of headache pain, may alert the physician to this occurrence. Fortunately most people with headache, even persistent or severe headaches, do not have a tumour. In this work we review the literature about prevalence of headache as an isolated/early symptom of brain tumour and report our experience.

Multicenter Study
Does headache represent a clinical marker in early diagnosis of cerebral venous thrombosis? A prospective multicentric study.
The main aim of this study is to look for early clinical markers of cerebral venous thrombosis (CVT). As headache represents the major clinical manifestation at presentation we focused our attention on this symptom. We present the preliminary results of a prospective multicentric study that includes cases diagnosed as CVT in the participating centres. ⋯ The onset of pain was mostly acute-subacute (38.5%-50.0%) and the intensity moderate-severe (37.0%-51.9%). On univariate analysis, we found a positive correlation between CVT, acute headache onset (p=0.001) and severe headache (p=0.004). These preliminary results seem in accordance with our previous findings in the retrospective study, suggesting that CVT is more often associated with acute-onset headache of severe intensity.

The International Classification of Headache Disorders 2nd Edition (ICHD-II), published in 2004, marks an unquestionable progress from the preceding 1988 edition, but the in-depth analysis it offers is not immune from drawbacks and shortcomings. First of all, it is still basically a classification of attacks and not of syndromes. For the migraine group, while the revised classification more accurately characterises migraine with aura, it fails to provide a sufficiently structured description of those forms of migraine without aura that over the years evolve to so-called daily chronic forms. ⋯ The inclusion of short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) in the cluster headache group is bound to generate some perplexity, while the recognition of new daily persistent headache (NDPH) included in the group of other primary headaches as a separate clinical entity appears somewhat premature. Doubts are also raised by the actual existence of triptan-overuse headache, which ICHD-II includes in Group 8 among medication-overuse headaches. Finally, the addition of headache attributed to psychiatric disorder, which is certainly a good option in perspective, is not yet supported by an adequate systematisation.

Headaches may have a wide range of impact on patients' lives. We report the results of Italian studies in which disability and health-related quality of life (HRQOL) in patients with different primary headaches were evaluated. The Short Form 36 (SF-36) was used to assess HRQOL; the Migraine Disability Assessment Score questionnaire (MIDAS) was used to assess disability in patients with migraine without aura or with chronic migraine. ⋯ The mean MIDAS total score was 23.4 in 264 patients with migraine without aura, and 79.2 in 150 patients with chronic migraine. Mean SF-36 scores in migraine without aura (68 subjects), chronic migraine (84) and cluster headache (56) were lower than those from the Italian general population, with significant differences for 3 scales in migraine without aura, for 6 in chronic migraine, and for all scales in cluster headache. Our results confirmed a marked personal and social burden in patients with migraine without aura, and also in the less well-studied forms of primary headaches, cluster headache and chronic migraine.

Patients with subarachnoid haemorrhage (SAH) frequently describe the occurrence of an underestimated or even ignored severe headache in the days or weeks preceding the bleeding. If recognised early, this warning headache might lead to specific investigations and, if indicated, a surgical approach might avoid a dramatic haemorrhagic event. In a recent and exhaustive systematic review, the incidence of a sentinel headache (SH) was evaluated in a range of 10-43% of SAH patients. ⋯ Nevertheless, a warning headache can precede a SAH in unruptured aneurysm even without a minor bleeding. Underestimation or misdiagnosis of SH depends on incorrect evaluation of the headache characteristics (unusual, severe, abrupt, thunderclap), overestimation of cranial CT sensitivity (false negative increasing over the elapsing time), failure to perform lumbar puncture (LP) in patients with negative CT, incorrect evaluation of CSF findings (xanthochromia may be absent in the first 12 h) and failure to differentiate traumatic tap from true SAH. Considering the diagnosis of SH in all cases of a severe, sudden-onset (thunderclap) headache, and performing all the appropriate diagnostic exams, including LP if necessary, could prevent subsequent massive bleeding and its invalidating or fatal consequences.
