Migraine, suicidal ideation, and suicide attempts.

Area of Science:

• Neurology
• Psychiatry
• Epidemiology

Background:

• Migraine is a common neurological disorder.
• Major depression is a leading cause of disability worldwide.
• The relationship between migraine subtypes and suicidal behaviors requires further clarification.

Purpose of the Study:

• To investigate the association between migraine with aura and migraine without aura and the risk of suicide attempts and suicidal ideation.
• To examine the impact of coexisting major depression on these risks.

Main Methods:

• Retrospective cohort study design.
• Analysis of suicide attempt and ideation rates across four groups: migraine with aura alone, migraine with aura and depression, migraine without aura alone, and migraine without aura and depression.
• Comparison with a control group without migraine or major depression.

Main Results:

• Migraine with aura, both alone and with coexisting major depression, was significantly associated with higher rates of suicide attempts and suicidal ideation compared to controls.
• The combination of migraine with aura and major depression showed a higher risk than the sum of their individual risks.
• Migraine without aura was not associated with an increased risk of suicide attempts or suicidal ideation.

Conclusions:

• Migraine with aura is a significant risk factor for suicidal behaviors.
• The presence of aura, rather than migraine itself, appears to be the critical factor in this association.
• Clinical attention to suicidal risk is warranted in patients with migraine with aura, particularly those with coexisting major depression.
