Introduction:
Chronic migraine is the most frequent complication of migraine. It is defined by the presence of headache on 15 or more days a month, of which at least eight must meet the criteria of migraine without aura for a minimum of three months. In addition they must not be due to medication abuse or attributable to any other cause.
Development:
The prevalence of chronic migraine ranges between 1-3% of the population and its incidence has been estimated to be 2.5% per year. It produces from four to six times more disability, decreased productivity and disruption of quality of life than episodic migraine. The development of chronic migraine has been associated with both non-modifiable risk factors (being female, low socio-economic status and level of schooling) and modifiable risk factors (anxiety, depression, sleep apnoea/snoring, obesity, consumption of painkillers and caffeine). Patients with chronic migraine suffer from chronic pain, anxiety or depression two to three times more often than those with episodic migraine. Management requires identification and control of the risk factors that predispose patients to develop the condition, detoxification therapy in the event of abuse of analgesics, specific treatment for migraine attacks and preventive treatment. The effectiveness of the preventive drugs topiramate and Onabotulinumtoxin A in this complication of migraine has been proved in large-scale placebo-controlled clinical trials.
Conclusions:
Chronic migraine is a common condition that requires global management aimed at reducing the frequency of the attacks, lowering the associated disability and improving the patients' quality of life.
Insights
Chronic migraine, a frequent complication of migraine, significantly increases disability and impacts quality of life. Effective management involves identifying and controlling risk factors, alongside specific and preventive treatments.
Area of Science:
- Neurology
- Public Health
Background:
- Chronic migraine is a common complication of migraine, characterized by headaches on 15+ days/month.
- It affects 1-3% of the population and causes significant disability compared to episodic migraine.
Purpose of the Study:
- To summarize the epidemiology, risk factors, and management of chronic migraine.
- To highlight the impact of chronic migraine on quality of life and productivity.
Main Methods:
- Review of epidemiological data on chronic migraine prevalence and incidence.
- Identification of modifiable and non-modifiable risk factors associated with chronic migraine development.
- Summary of current management strategies, including risk factor control and pharmacological treatments.
Main Results:
- Chronic migraine is associated with higher rates of disability, decreased productivity, and poorer quality of life.
- Risk factors include female gender, low socioeconomic status, anxiety, depression, obesity, and medication overuse.
- Preventive treatments like topiramate and Onabotulinumtoxin A have demonstrated effectiveness.
Conclusions:
- Chronic migraine is a prevalent condition requiring comprehensive management.
- Management should focus on reducing attack frequency, mitigating disability, and enhancing patient quality of life.
