Transient Ischemic Attack Versus Seizure: Use of Complete Blood Count Parameters for Differential Diagnosis

Introduction: Seizures are an important group of diagnoses in the differential evaluation of Transient Ischemic Attack (TIA) because of their variable and temporary signs and symptoms. Physicians must frequently rule out TIA in asymptomatic patients with normal diagnostic neuroimaging. Aim: The current study aimed to investigate the efficacy of Complete Blood Count (CBC) components in the differential diagnosis of TIA and seizures. Materials and Methods: Our study was a retrospective casecontrol study. Patients admitted to the Emergency Department (ED) and hospitalized with an initial diagnosis of TIA or seizure at the neurology clinic of Erzurum Ataturk University Training Hospital between January 1, 2012, and December 31, 2014, were recruited for the study. Patients with inaccessible or missing data were excluded. Results: We identified 1,459 ED admissions that resulted in neurology clinic hospitalizations of patients with initial diagnoses of TIA (n=911) and seizure (n=420) over a 24-month time period. A total of 128 patients were excluded from the study. Conclusion: We conclude that CBC may have a diagnostic value on TIA and seizure differentiation, but this is limited because of statistical and clinical incompatibility. Elevated White Blood Cells (WBC) values of seizure patients compared with TIA patients’ may help clinicians at the preliminary phase of diagnostic studies. We conclude that age is a remarkable and valuable demographic parameter in addition to physical examination, laboratory and imaging studies.
