Migraine and bipolar disorder are two multifaceted conditions that initially might not seem to be linked. Recent studies, though, have found some very interesting links between them, with common mechanisms and overlapping symptoms. Recognizing these similarities can help both patients and providers to better manage these conditions.
What Is Bipolar Disorder?
Bipolar disorder is a psychiatric illness characterized by extreme mood, energy, and behavior swings. Individuals with bipolar disorder have depressive episodes, during which they are sad and withdrawn, as well as hypomanic or manic episodes, in which moods are elevated or irritable, thoughts are racing, and behavior is impulsive.
There are three primary types of bipolar disorder:
Bipolar I Disorder: This condition is characterized by one or more manic episodes, in which hypomania or major depression usually exists.
Bipolar II Disorder: This disorder includes one hypomanic and one major depressive episode, without experiencing full-manic episodes.
Cyclothymia: This milder form involves frequent hypomanic and depressive episodes over at least two years, though the symptoms are less severe than those seen in Bipolar I and II.
Studies have revealed that individuals with bipolar disorder are more likely to have complications in their health, such as decreased life expectancy and higher suicide rates, than the general public. Various risks, such as premature diagnosis, suicide in family history, and a history of trauma in childhood, can increase these risks.
How Is Migraine Related to Bipolar Disorder?
The connection between migraine and bipolar is two-way, i.e., having one condition increases your risk of developing the other. Research has discovered that individuals who have migraines, particularly migraines with aura, are three times more likely to develop bipolar disorder. Conversely, approximately one-third of individuals with bipolar disorder also have migraines.
Several reasons could be responsible for this association:
Genetics: A history of either condition in the family can predispose to developing the other. For example, those with a family history of bipolar disorder and major depressive episodes are at higher risk of developing migraines.
White Matter Hyperintensities (WMH): These MRI-visible brain lesions are prevalent in individuals with bipolar disorder and may also be involved in precipitating migraines.
Inflammatory Markers: Elevated levels of inflammatory mediators, including tumor necrosis factor alpha (TNF-α), have been reported during both manic states and acute migraine attacks.
Neurotransmitters: Both share abnormalities in neurotransmitters such as serotonin, dopamine, and glutamate, which are crucial in mood and pain regulation.
Shared Features and Comorbidities
Migraine and bipolar disorder have some similarities in that they are both episodic and stress-sensitive. Both have been found to get worse with trauma during childhood, an association that is related to earlier age of onset, frequency, and severity in bipolar disorder as well as increased rates of migraine.
In addition, these conditions tend to come with other medical conditions such as anxiety, ADHD, epilepsy, and multiple sclerosis. These co-occurring conditions highlight the importance of using a holistic strategy in both diagnosis and treatment.
Treatment Challenges and Options
Treatment of both migraine and bipolar disorder can be complicated since some of the drugs used to treat one condition can worsen the other. For instance:
Tricyclic Antidepressants: Though these are usually prescribed to forestall migraines, they may precipitate manic attacks in individuals with bipolar disorder.
Beta Blockers: Useful for migraines, but they exacerbate depressive illness in individuals with bipolar disorder.
Certain medications, for example, mood stabilizers such as lithium and lamotrigine, anticonvulsants such as topiramate and valproate, and atypical antipsychotics such as quetiapine, may treat both disorders. Apart from medications, other treatments like psychotherapy, neuromodulation, and social rhythm therapy can also benefit individuals living with both migraine and bipolar disorder.
Who Should You Consult?
Treatment of migraine and bipolar disorder is usually a team effort. Migraines can be managed by headache specialists, neurologists, while bipolar disorder should be diagnosed and treated by psychiatrists. Psychologists or therapists can be helpful through psychotherapy. Primary care physicians and social workers can also assist in coordinating care and providing a balanced treatment plan.
Understanding the complicated relationship between migraine and bipolar disorder is crucial for proper management. Through identifying the common factors and tailoring treatment, medical practitioners can assist individuals to live healthier, more balanced lives.
