A brand new research in Brain and Behavior has unraveled the connection between migraines, bipolar dysfunction, and affected person outcomes. Nicole Sekula and colleagues carried out an 11-year longitudinal research demonstrating that these with bipolar dysfunction and migraines skilled worse signs of melancholy, mania, and a diminished high quality of life on common. In addition, if these people have been additionally prescribed lithium, their signs of mania have been worse than these with migraines not taking lithium.
Approximately 30% of individuals with bipolar dysfunction additionally endure from migraines, in comparison with round 17% of the overall inhabitants. Prior analysis has discovered that these with migraines and bipolar dysfunction are extra weak to extreme melancholy, suicidal ideation, and nervousness problems. In addition, researchers have discovered that these with bipolar dysfunction and migraines relapse extra often in the event that they take lithium for his or her bipolar analysis.
Sekula and colleagues felt extra analysis was mandatory to grasp how this discovering could affect sufferers. If lithium is discovered to extend signs in folks with bipolar dysfunction and migraines, it would require modifications in remedy protocols for individuals who match the factors.
The analysis staff recruited 538 people recognized with bipolar I. Thirty-one p.c of the participant group suffered from migraines; the rest didn’t. From 2005-2016 these individuals stuffed out well being questionnaires each two months and measures of mania and melancholy yearly. The individuals have been divided into 4 comparability teams: these with migraines taking lithium, these with out migraines taking lithium, these with migraines not on lithium, and people with out migraine taking lithium. These 4 teams have been then in contrast utilizing the information collected on melancholy, mania, and high quality of life.
This course of revealed that these with migraine expertise extra melancholy, extra mania, and decrease high quality of life scores than these with out migraine. This was true no matter lithium use or not. Over 11 years, when topics who suffered from migraines have been prescribed lithium, signs of mania have been considerably worse than all different teams within the research.
The analysis staff identifies a couple of limitations to contemplate. First, the information was collected via self-report for migraine historical past and lithium use. Medical data weren’t used to confirm participant claims. Research discovered self-report strategies for continual circumstances to be dependable, however medical data would have ensured the information was not skewed.
Second, blood assessments to find out the quantity of lithium an individual has taken might have been useful data. If blood assessments revealed that individuals weren’t taking their medicine constantly, their information shouldn’t be included. Third when people started experiencing migraines and after they started to take lithium was unknown. These dates might need been useful in understanding if the timing of migraine onset was pertinent to lithium use or poor outcomes.
Undeterred by these limitations, Sekula and colleagues suggest that lithium not be prescribed for these bipolar I sufferers who expertise migraines. They state, “Our findings, along with published observations, suggest that lithium is in fact contraindicated in comorbid bipolar disorder/migraine and other mood stabilizing medications should be considered.”
The research, “Lithium use associated with symptom severity in comorbid bipolar disorder I and migraine“, was authored by Nicole Sekula, Anastasia Yocum, Steven Anderau, Melvin McInnis, and David Marshall.
