The objective was to investigate and classify headaches in 109 consecutive adult patients with epilepsy. A semi-structured interview was performed in those who confirmed such symptoms (65%). Interictal headaches were present in 52%; 20% had interictal migraine. ⋯ Seizures often trigger postictal headaches with migraine features, which often are associated with interictal migraine. Migrainous headaches sometimes proceed into epileptic seizures. The comorbidity of migraine and epilepsy should receive ample clinical attention, as it may influence antiepileptic drug choice, and the headache may need specific treatment.

Coexistence of hemifacial spasm (HFS) and trigeminal neuralgia (TN) is a rare entity known as painful tic convulsif (PTC). Here, we present a case of right-sided HFS after which left TN developed, which is an unusual form of PTC. Both disorders were caused by bilateral vascular compression of the cranial nerves and successfully treated with botulinum toxin and carbamazepine. As PTC is benign in nature and can be treated with botulinum toxin, neuroradiological investigations should be performed for an accurate aetiological diagnosis, particularly in young patients with atypical disease manifestations.

The objective was to retrospectively characterise the efficacy of memantine as preventive therapy in a series of patients with frequent migraine. Patients in a university headache clinic completed a survey regarding their experience with memantine, and medical records were reviewed. All patients who received memantine as preventive therapy for migraine over a 15-month period were mailed surveys and consent forms for record review. ⋯ Side effects were uncommon and generally mild. This limited retrospective case review suggests that memantine may be an effective preventive therapy for patients with frequent migraine. A prospective trial is warranted.

A striking feature of migraine is the difference between the estimated migraine prevalence and the actual number of migraineurs consulting their general practitioners (GPs). We investigated the impact of a sensitisation campaign on migraine in a large cohort of patients, living in a district of Rome. The study involved 10 GPs and a population of about 12 000 people, contacted by mail and posters located in GP clinics. ⋯ This study confirms that a large number of migraine patients never see a doctor for their headache. This awareness campaign is likely to identify the severest cases of undiagnosed migraineurs. However, mailing campaigns do not seem to be so effective in bringing undiagnosed migraine patients into the primary care setting, and more efficient strategies have to be planned.

Meta Analysis
Genetic association study and meta-analysis of the HTR2C Cys23Ser polymorphism and migraine.
The objectives of this study were to determine if the HTR2C Cys23Ser polymorphism is associated with migraine in a case-control study, and to perform a meta-analysis with present and previous available studies. The HTR2C gene is located at the Xq24-q28 chromosomal band. This band was linked to migraine with aura (MA) in two Australian families. ⋯ In the association study we found no significant differences among migraine and MA patients for this polymorphism. In the meta-analysis, under the fixed-effect model, the Ser allele did not confer higher risk for suffering MA (pooled OR=1.1; 99% CI=0.8-1.5, p=0.499). Our study did not confirm the HTR2C Cys23Ser polymorphism as a risk factor for migraine and MA.
