We present a theory according which a headache treatment acts through a specific biological effect (when it exists), a placebo effect linked to both expectancy and repetition of its administration (conditioning), and a non-specific psychological effect. The respective part of these components varies with the treatments and the clinical situations. During antiquity, suggestions and beliefs were the mainstays of headache treatment. ⋯ The announcements of doctors strongly influence the beliefs of patients, and in consequence their pain and anxiety sensibilities; this modulates the amplitude of the placebo and the non-specific psychological effects and is therefore a major determinant of the therapeutic success. Furthermore, any repetitive contact, even through a placebo, may interfere positively with the psychopathological co-morbidity. One has to keep in mind that the non-specific psychological interactions play a major role in the improvement of the majority of the headache sufferers.

Migraine is a predominantly female disorder. Menarche, menstruation, pregnancy, and menopause, and also the use of hormonal contraceptives and hormone replacement treatment may influence migraine occurrence. Migraine usually starts after menarche, occurs more frequently in the days just before or during menstruation, and ameliorates during pregnancy and menopause. ⋯ In fact, migraine with aura represents a risk factor for stroke, cardiac disease, and vascular mortality. Studies have shown that administration of combined oral contraceptives to migraineurs may further increase the risk for ischemic stroke. Consequently, in women suffering from migraine with aura caution should be deserved when prescribing combined oral contraceptives.

We investigated the prevalence of migraine (MIG), tension-type headache (TTH), and chronic headache in a population-based sample in Germany. A total of 18,000 subjects aged between 18 and 65 years were screened from 2003 until 2005 using a validated questionnaire. Overall 9,944 participants (55.2%) responded (mean age 43 ± 13.1 years, 52.7% women). ⋯ It is of note that the number of subjects with chronic headache is small in all age groups. The results of our large, population-based study provide reliable, age- and sex-specific estimates of the prevalence of primary headache disorders in Germany. The prevalence with respect to episodic and chronic primary headache disorders in Germany is comparable to other European countries and the USA.

Migraine attacks are believed to involve activation of the trigeminovascular system and trigeminal-parasympathetic reflex, which is mediated through the sphenopalatine ganglion (SPG). An implantable SPG neurostimulator has been developed to apply on-demand SPG stimulation for the treatment of severe primary headache. The neurostimulator is implanted via an oral incision and placed along the maxilla, with the lead placed at the SPG. ⋯ Preventive and acute medications were used in 64 and 95% of the subjects, respectively, and provided a reported reduction of headache frequency, duration and pain. However, acute medications were frequently associated with headache recurrence and bothersome side effects. Results indicate that a majority of high-frequency, high-disability migraineurs, many of whom achieve pain relief with their current medications, have an interest in participating in a clinical investigation of an implantable SPG neurostimulator for the treatment of migraine headache.

Burning mouth syndrome has been reported as being more common in Parkinson's disease patients than the general population. While the pathophysiology is unclear, decreased dopamine levels and dopamine dysregulation are hypothesized to play a role. ⋯ Our patient had resolution of burning mouth symptoms when carbidopa/levodopa was replaced with a dopamine agonist. Based on our patient's clinical course, in conjunction with earlier studies assessing the relationship between burning mouth syndrome and Parkinson's disease, we discuss a potential role for dopamine in burning mouth syndrome in Parkinson's disease.
