Cognitive Changes
Many people with migraine also report cognitive difficulties like “brain fog,” reduced concentration, and memory lapses, especially during an episode (ictal phase). These symptoms can even persist on non-migraine days (the interictal phase) for those with chronic migraine or central sensitisation. While research is still evolving, factors like migraine subtype, co-occurring conditions such as anxiety and depression, and treatment side effects may all contribute to these cognitive effects. (9, 10)
This can affect work, social interactions, and self-esteem. Some treatments can also affect cognitive function, creating a delicate balance between symptom relief and side effects.

Migraine and mental health are closely linked. People with migraine are more likely to experience anxiety, depression, and other mood disorders. This is not a coincidence: the same parts of the brain involved in migraine also play a role in mood regulation. (11)
People with migraine are:
- 2.5 times more likely to experience suicidal thoughts
- 2 to 3 times more likely to live with depression
- 5 times more likely to experience anxiety
- 2.5 to 3 times more likely to have bipolar disorder (12)
These risks are higher for those with chronic migraine.
Beyond mental health, migraine is also frequently comorbid with:
- Sleep disorders, such as insomnia
- Gastrointestinal conditions, like irritable bowel syndrome (IBS) and cyclical vomiting syndrome (CVS)
- Autonomic nervous system disorders, such as dysautonomia
- Cardiovascular conditions, including hypertension, coronary heart disease, and even stroke
These comorbidities can make migraine harder to manage, interacting in ways that can increase the risk of migraine episodes becoming chronic, lower quality of life, and complicate treatment and self-management, further compounding its emotional burden. (13, 14)
Managing multiple chronic conditions alongside migraine can be physically draining and emotionally overwhelming.
Importantly, even people with migraine who don’t have a diagnosed mental health condition can still experience emotional effects. One study found that women with migraine—especially chronic migraine—had more anxiety, trouble sleeping, repetitive negative thinking, and feelings of helplessness, compared to those without migraine. This shows that migraine itself can affect how we feel and think, even when no mental illness is present. (15)
This highlights the need to identify and address comorbidities – especially mental health – and integrating emotional and psychological support as part of care for everyone living with migraine.
