Migraine and olfactory stimuli.

Migraine patients often report intolerance to odours. Migraineurs report odours may trigger attacks, that they experience osmophobia during attacks, and olfactory hypersensitivity between attacks. In this paper we discuss olfactory mechanisms in migraine.

Lateralization in cluster headache: a Nordic multicenter study.

A slight predominance of cluster pain on the right side has been reported in several studies. The aim of this large retrospective Nordic multicenter study was to estimate the prevalence of right- and left-sided pain in cluster headache (CH) patients with side-locked pain, the prevalence of side shifts in episodic and chronic CH patients, and the occurrence of cranial autonomic symptoms related to pain side. Among 383 cluster patients, 55 (14%) had experienced pain side shift.

Diminished nocturnal lipolysis in cluster headache: a sign of central sympathetic dysregulation?

Background: It is unclear whether the autonomic symptoms during cluster headache (CH) attacks are of central or peripheral origin. A metabolic change such as altered lipolysis would reflect a central autonomic dysfunction.

Objective: To study nocturnal lipolysis in CH patients and healthy control subjects.
