Co-occurrence of major depression or suicide attempt with migraine with aura and risk for unprovoked seizure

SummaryWe hypothesized and found that the co-occurrence of migraine with aura (MA) with major depression (MD) or with suicide attempt (SA) increases the risk for developing unprovoked seizure more than these conditions alone. Number of conditions showed a linear relationship to seizure risk. This may reflect a new condition cluster defined by MA, MD, SA and unprovoked seizures. Identifying the biological underpinnings this cluster may affect clinical diagnosis and treatment.
