Headaches are often overlooked as a common yet manageable condition, but researchers suggest they may have more serious implications. A groundbreaking study from Aarhus University in Denmark has found a significant link between headache disorders and an increased risk of suicide.
The 25-year-long research, published in JAMA Neurology, sheds light on how various types of headaches—ranging from migraines to tension-type headaches—could contribute to suicidal tendencies. The study's findings emphasise the need for better mental health interventions for those suffering from chronic headaches.

Understanding the study
The study, titled 'Risk of Attempted and Completed Suicide in Persons Diagnosed with Headache,' examined data from 1,19,486 individuals diagnosed with headaches alongside a comparison group of 5,97,430 individuals with no reported headache disorders.
Researchers focused on several headache types, including migraines, tension-type headaches, posttraumatic headaches, and trigeminal autonomic cephalalgia.
One of the study’s key takeaways is that individuals suffering from headaches are at a greater risk of attempting or completing suicide compared to those without headache disorders.
Previous research primarily linked migraines with higher suicide rates. Still, this study expands that connection to a wider range of headache disorders, highlighting the broader mental health risks associated with chronic pain conditions.
What did the study reveal?
The research discovered alarming statistics:
Attempted suicides: 0.78% of individuals diagnosed with headaches attempted suicide, compared to 0.33% in the control group.
Completed suicides: Over 15 years, 0.21% of people diagnosed with headaches died by suicide, versus 0.15% in the control group.
Migraine-specific risks: People with migraines had a ratio of 1.71 for attempted suicide and 1.09 for completed suicide, suggesting a strong connection between migraines and suicidal tendencies.
Additionally, the study found that individuals suffering from headaches were more likely to have coexisting medical and psychiatric conditions, such as cancer, cardiovascular disease, stroke, head injuries, mood disorders, and substance use disorders. These factors likely contribute to the increased suicide risk observed in the study.

A persistent and widespread risk
One notable aspect of the study was that the increased risk of suicide remained consistent across various demographic factors, including sex, age, income, and education levels. This suggests that headache disorders pose a universal risk, regardless of an individual's social or economic background.
Interestingly, while the suicide risk was still present among individuals with mood or substance use disorders, the association was somewhat weaker. This indicates that the relationship between headaches and suicidal tendencies is not solely dependent on existing mental health conditions. Instead, headaches represent an independent risk factor that requires attention.
What can be done?
The findings of this extensive study support the idea that headache disorders should not be treated in isolation. Instead, a comprehensive healthcare approach is needed—one that includes medical and behavioural health assessments. The study’s authors highlight the necessity for patients diagnosed with headaches to receive concurrent mental health evaluations and treatment to reduce their risk of suicide.
In their concluding remarks, the researchers emphasised, "The robust and persistent association with attempted and completed suicide across headache disorders suggests that patients diagnosed with headache may benefit from concurrent behavioural health evaluation and treatment."
