Cluster headache, one of the most painful diseases known to man, is genetically correlated with risk-taking behaviour, ADHD, depression and musculoskeletal pain, and smoking is a causal risk factor, according to an article published in Annals of Neurology.

Patients with cluster headache suffer from various sleep problems, such as insomnia, which also occur in periods when the patient is symptom-free and should be considered during treatment. This is shown by researchers at Karolinska Institutet in a study recently published in The Journal of Headache and Pain.

Each year, the Swedish Brain Foundation supports qualified research on the brain and other nervous systems, as well as diseases, injuries, and disabilities throughout the nervous system. Andrea Carmine Belin runs one of the 44 research projects at Karolinska Institutet that have been awarded this year's research grant from the Swedish Brain Foundation.

Between 13 and 19 March 2023, neuroscientists around the world took the initiative to spread the word about the importance of brain science as part of the "Brain Awareness Week". The Strategic Neuroscience Research Network (StratNeuro) at Karolinska Institutet took the opportunity to initiate a recurring outreach event to spark enthusiasm and raise awareness for neuroscience research, which was also part of the global campaign.

Cluster headache, or Horton’s syndrome, is so painful that it is sometimes referred to as “suicide headache”. Thanks to a donation of SEK 35 million from financier and philanthropist Rune Andersson, research group leader Andrea Carmine Belin will very soon be setting up the world’s first research centre specialising exclusively in cluster headaches.
