Brief Summary

The pathophysiological mechanisms that underlie primary headache disorders, such as migraine and cluster headache (CH), are complex and not yet fully clarified. While there is today little doubt that activation of the trigeminovascular system (TGVS) is responsible for the headache pain, the primary mechanisms, probably centrally mediated, leading to its activation and the generation of pain are still largely obscure. The trigeminal system is supposed to play a central role not only in migraine but also in cluster headache pathology. In vitro studies have demonstrated the expression of BDNF in trigeminal ganglion neurons. BDNF release is induced by trigeminal stimulation and nociceptive inputs. BDNF is a member of the neurotrophin family and has been recognized as an important modulator of nociceptive pathways. Interestingly, BDNF is co-expressed with CGRP in trigeminal ganglion neurons. CGRP is one of the key molecules in migraine and cluster headache pathogenesis. BDNF is an important marker of neuronal plasticity. It has also been associated with pain processing. Increased BDNF levels are observed in chronic pain syndromes. In order to understand the role of BDNF associated with other factors such as gender on headache attacks we aimed to determine whether migraine and cluster headache is correlated with brain derived neurotrophic factor (BDNF) level, gender and age.

Outcome Measures

Primary Outcomes (1)

  • Gender differences and features of the clinical course of primary headaches

    Increasing of BDNF during headache attacks in women were more than men

    2 years

Study Arms (3)

Migraine

In migraineurs, venous blood samples will be collected twice: outside and during migraine attacks prior to pain medication. Analysis of BDNF performed using enzyme-linked immunosorbent assay technique.

Diagnostic Test: analysis BDNF

Tension type of headache

In patients with tension-type headache (outside attack) and healthy controls, one single blood sample will take. Analysis of BDNF performed using enzyme-linked immunosorbent assay technique.

Diagnostic Test: analysis BDNF

Cluster headache

In cluster headache patients serum samples will be collected in and outside cluster bout. Analysis of BDNF performed using enzyme-linked immunosorbent assay technique.

Diagnostic Test: analysis BDNF
