Migraines: The Genetic Link

Migraines are often thought of as a personal challenge—a condition that turns up unexpectedly, demanding dark rooms and quiet spaces. But for many, migraines often “run in the family.”

Research has long shown a hereditary link to migraines. In fact, about 70% of people with migraines have a first-degree relative (parent, sibling, or child) who also experiences them. This striking statistic underscores the genetic predisposition to migraine, although the exact genes involved are still under investigation.

Migraines are a polygenic condition, meaning multiple genes interact with environmental factors to influence your risk. Rare forms of migraine, such as familial hemiplegic migraine, have well-identified genetic mutations. However, the genetics of more common migraines remain complex and varied.

While sharing a genetic predisposition doesn’t mean you’re doomed to have migraines as severe or frequent as a family member, it’s an important factor in understanding your own risks.

Families affected by migraines often have shared experiences, but it’s important to recognize that everyone’s migraine journey is unique. For some, migraines may strike only a few times a year, while for others, they’re chronic and debilitating. Genetic predisposition determines susceptibility, not the frequency or severity of attacks.

However, shared genetic risk can lead to shared anxieties. Many parents with migraines worry about passing them on to their children. Likewise, children who watch a parent struggle with migraines may develop their own fears about the condition.

Reassuringly, lifestyle and environmental factors have a vital impact on migraines, and there are ways to mitigate the impact of them even within genetically predisposed families.

Encourage open conversations about migraines: Create a safe space for family discussions about migraines. Educate children and other family members about the condition, emphasizing that it’s manageable with the right tools and treatments.

Track and identify triggers: Encourage each family member to keep a migraine diary. Knowing personal triggers, such as stress, sleep disruptions, or certain foods, can help with prevention and control.

Focus on healthy lifestyle habits: Families can benefit from shared wellness goals like consistent meal times, proper hydration, regular sleep schedules, and stress management techniques. These habits can significantly lower migraine frequency.

Seek professional guidance: If migraines are a recurring issue in your family, consult a headache specialist. Genetic predisposition can guide personalized treatment strategies, including both preventive measures and acute care.

Address anxiety about heredity: For parents concerned about passing migraines to their children, it’s important to shift focus from worry to empowerment. Equipping children with knowledge and strategies can help them feel prepared rather than fearful. Normalize the condition by explaining that migraines, though challenging, are a medical issue like any other—one that can be managed with the right support. Encourage children to share their experiences if they develop symptoms and involve them in proactive lifestyle choices.

Migraines are a chronic condition, but they don’t have to control your life or your family’s. As a neurologist, I’ve seen firsthand the difference that education, treatment, and support can make. With a proactive approach, you can turn what feels like an inherited burden into an opportunity for connection, support, and resilience.
