Objectives: Since neurogenic inflammation and hemoconcentration have a prominent role in the pathophysiology of migraine, evaluation of hemogram parameters and indices showing inflammation can yield important information. In this study, we have investigated blood cell counts and ratios, systemic inflammation index (SII), systemic inflammation response index (SIRI) and red cell index (RCI) in the painless periods between pain attacks in patients with episodic migraine without aura.
Methods: Hemogram data of both 309 patients diagnosed with migraine without aura related to pain-free periods and 199 healthy individuals were retrospectively retrieved from hospital records.
