Structural white matter abnormalities in pain-modulating, regions are present in migraine. Whether they are associated with pain chronification and with cognitive reserve is unclear. ⋯ Long-term chronic migraine patients show abnormalities in anterior white matter tracts, particularly of the right hemisphere, involved in pain modulation emotion, cognition and resilience. Robustness in these areas is associated with a higher cognitive reserve, which in turn might result in a lower tendency to migraine chronification.

Hemicrania continua (HC) is a rare chronic headache disorder, typically accompanied by cranial autonomic features and responding to therapeutic doses of indomethacin. The pathophysiology of hemicrania continua is not fully understood. ⋯ The biology of hemicrania continua may be activated post-craniotomy just as can be seen with other primary headache disorders.

Sleep disorders and primary headaches are both more prevalent among nursing staff than in the general population. However, there have been no reports about the comorbidity of poor sleep and primary headaches among nursing staff. ⋯ Comorbidity of poor sleep and primary headaches among nursing staff is common. Therefore, sleep quality should be carefully evaluated in nurses with primary headaches.

Observational Study
Productivity losses attributable to headache, and their attempted recovery, in a heavy-manufacturing workforce in Turkey: implications for employers and politicians.
Headache disorders cause substantial productivity losses through absenteeism and impaired effectiveness at work (presenteeism). We had previously found these losses to be high in a mostly male, heavy-manufacturing workforce at Ford Otomotiv Sanayi AŞ (FO), in north-western Turkey. Here we aimed to confirm this finding in a year-long study to eliminate any effect of seasonal variation. The question then was how much of this lost productivity could be recovered by the effective provision of headache care. ⋯ The high productivity losses in this young mostly male workforce correlated with but were not wholly explained by headache frequency. A small minority of employees with high-frequency headache contributed highly disproportionately to the productivity losses. These should be the target of interventions aimed at productivity recovery. It is not clear what form such interventions should take: making headache care optimally available is not of itself sufficient.

Chronic migraine is one of the most common diseases in the world and it is often associated with medication overuse that can worsen the headache itself. Thus, it is important to adopt effective therapies to relieve pain and improve patients' quality of life. The PREEMT studies have already demonstrated the effectiveness of OnabotulinumtoxinA in the treatment of chronic migraine. With this in mind, the aim of this real life observation has been to assess the clinical improvements as well as the impact on the quality of life of patients being regularly (every three months) administered this therapy. ⋯ This study outpoints that OnabotulinumtoxinA treatment is an effective treatment to reduce the headache-related disability and improve patients' quality of life when patients are treated regularly every three months and consistently overtime. Therapy discontinuation leads to a general worsening of health-related quality of life. Long term treatment over one year confirms a consistently positive and sustained trend of improvement with a high safety profile.
