Craniocervical dystonia is a focal or segmental dystonia in its distribution, classically known as spasmodic torticollis when in its pure cervical presentation. Although craniocervical dystonia has been recognized as a possible cause of headache since the publication of the second version of International Classification of Headache Disorders, there are few studies about this entity. ⋯ Headache attributed to craniocervical dystonia has been poorly studied. There is a need for more studies to evaluate its characteristics and treatment.

Management of chronic migraine (CM) or new daily persistent headache (NDPH) in those who require aggressive outpatient and inpatient treatment is challenging. Ketamine has been suggested as a new treatment for this intractable population. ⋯ Subanesthetic ketamine infusions may be beneficial in individuals with CM or NDPH who have failed other aggressive treatments. Controlled trials may confirm this, and further studies may be useful in elucidating more robust benefit in a less refractory patient population.

We aimed to study the role of attachment style on headache severity and psychological symptoms in migraineurs children/adolescents. Moreover, we investigated the association between attachment style, migraine severity, and psychological symptoms. ⋯ Ambivalent attachment style may be a common vulnerability factor that impacts on pain severity, anxiety, depression, and somatization symptoms in young migraineurs. In particular, the present study provides the first evidence of the role of insecure attachment on the relationship between pain severity and psychological symptoms in migraine children.

There are limited literature data on migraine-like accompanying features (MLF) in patients with cluster headache (CH). These symptoms are frequently reported by patients and may delay CH diagnosis. ⋯ Our study confirms the high proportion of CH patients with MLF, which is reported in literature. The presence of MLF seems to relate to some peculiar demographic and clinical characteristics of CH sufferers. Whether these features influence the response to therapy remains to be determined.

Hemicrania continua (HC) is a primary chronic headache disorder, characterized by a continuous and strictly unilateral headache, with possible cranial autonomic symptoms during episodes of pain exacerbation. The unilateral headache generally responds well to indomethacin; however, continuous indomethacin intake is often not tolerated due to severe adverse effects, like hypertension, gastrointestinal discomfort (especially if combined with aspirin), slightly increased risk of vascular events, and bronchial spasms. Therefore, alternative treatment options are desperately needed. Non-invasive vagus nerve stimulation (nVNS) has been shown to be effective in patients with cluster headache, another trigeminal autonomic cephalalgia (TAC), with cranial parasympathetic autonomic activation during the attacks.
