The personal and economic impact of headache disorders

Headache disorders are not just a personal burden – they also come with a significant economic cost. Their impact reaches far beyond the individuals affected, placing a strain on society as a whole.

Neurological disorders are on the rise everywhere

The World Health Organization (WHO) ranks headache disorders among the leading causes of disability worldwide, with a profound impact on those affected. In fact, the latest Global Burden of Disease Study found that neurological disorders now represent the largest overall disease burden worldwide. Together, they place a greater burden on global health than cardiovascular diseases, long considered the world’s leading health challenge.

Neurological conditions are not just a problem in Europe or other ‘Western’ countries. The WHO estimates that about one in three people worldwide lives with a neurological disorder. That’s around three billion people in total, far more than previously thought. A worrying trend is apparent, too: the findings suggest that, over the past 31 years, disability, illness, and premature death caused by neurological disorders have increased by 18% worldwide.

Headaches – a global health problem

Of the 37 neurological disorders included in the study, tension-type headache is the most common, affecting around two billion people. Migraine comes next, affecting about one billion. The researchers believe several factors are driving this increase, including population growth, ageing populations, and greater exposure to environmental and lifestyle-related risks.

Germany is no exception

Headache disorders also top the list of healthcare issues in Germany: studies from the Kiel Pain Clinic estimate that around 54 million people are affected. The two most common headache disorders are tension-type headache (38.3%) and migraine (27.5%). Together, they account for about 92% of all headaches. Overall, around 71% of people in Germany experience headaches at some point in their lives. Every day, an estimated 900,000 people have a migraine attack. Around 100,000 of them are unable to work because of their symptoms.

Professor Hartmut Göbel, a neurologist and founder of the Kiel Pain Clinic, points out that both the frequency and the severity of headaches and migraine attacks have increased markedly in recent years. He believes our modern lifestyle may be part of the reason. Today’s world places our nervous system under constant pressure. The demands keep growing, and for many people the strain eventually becomes too much. Even more concerning is that, according to Göbel, although more people need treatment, only around 20% of those affected in Europe actually receive medical care. In other words, only one in five people with a headache disorder sees a doctor. Göbel says that many others turn to unconventional treatments that are not supported by scientific evidence, which may make the problem even worse.

What headaches cost: figures from one hospital

The vast impact of headache disorders on society also comes at a huge economic cost, as numerous studies have shown. A study carried out at a large Swiss university hospital highlights just how expensive headaches can be in a healthcare setting. More than 60% of hospital employees reported having headaches during the research period. Because of sick leave and reduced productivity while at work, each affected employee lost the equivalent of around 10 working days per year. Altogether, the hospital estimated the financial impact at almost €10 million annually – more than 3% of its total personnel costs.

A heavy human and economic toll

Without proper information, an accurate diagnosis, and effective treatment, many people try to manage headaches on their own. Every day, an estimated three million people in Germany take headache medication. Besides increasing the risk of medication-overuse headache (read more in this article), the widespread practice of self-treatment also comes with a hefty price tag. Medication used to treat migraine – both prescription and over-the-counter products – is estimated to cost between €150 million and €500 million every year.

Headaches are also one of the leading causes of short-term sick leave. In Germany alone, migraine-related absences amount to the equivalent of 185,000 full-time employees being off work for an entire year. This is estimated to cost around €3.5 billion annually. On top of that, people who go to work despite having a headache often cannot perform at their usual level, adding another estimated €3 billion in lost productivity.

Overall, headache disorders cost Germany around €27 billion every year. Across the European Union, the annual cost is estimated at about €170 billion. These figures do not include unpaid work – such as looking after children, caring for family members, or running a household – that cannot be done because of headaches. Headache disorders are also linked to a higher risk of other health conditions. For example, people with migraine are up to seven times more likely to develop depression or anxiety disorders. They also have about twice the risk of cardiovascular disease, including heart attacks (read more about headache-related comorbidities in this article)

The invisible burden of headache disorders

Despite being so common, and so disabling, headache disorders are still significantly undertreated. Fewer than 20% of affected people receive medical care, and fewer than one in ten are offered appropriate preventive treatment. As a result, both the personal and economic burden continues to grow. Without proper treatment, headaches often become more frequent over time. This is known as chronification. What may begin as occasional attacks can gradually develop into chronic, ongoing pain. Chronic headaches have a devastating effect on quality of life. Everyday activities become difficult and many affected people become socially isolated as a result.

Because headaches are an invisible condition, they are still often dismissed as a minor inconvenience that people simply have to live with. The pain experienced during repeated, severe migraine attacks is difficult for others to fully understand. The effects on work, family life, leisure time, and society as a whole are also not always visible.

So, what can we do about this silent epidemic? We know far more today about how headache disorders develop, the disease burden, and the economic impacts than we did just a few years ago. Research has also made impressive progress in finding better ways to prevent and treat the various headache types. The challenge now is to put that knowledge into practice. Headache disorders need to become a much higher priority in healthcare.

Prevention and treatment go hand in hand

Access to proper medical care is essential to reducing personal suffering and limiting the wider social and economic impact. We should also use effective, long-term education and awareness initiatives wherever possible to help prevent headaches before they start. We know that some of the burden of headache disorders is a result of the way we live today. That gives us a clear starting point: identifying and reducing the everyday factors that can trigger or worsen headaches. Behavioural approaches to preventing migraine and tension-type headache – and, in turn, medication-overuse headache – have been shown in many studies to reduce both the frequency and the severity of attacks.

The first step is understanding what type of headache a person has. The next is learning which lifestyle changes and preventive strategies are most likely to help in the long term. People who understand their headaches have far more control over them than they realise. Better knowledge, better prevention, and better treatment can reduce not only individual suffering but also the enormous cost that headache disorders place on society.
