The aim of this study was to determine the level of serum NGRN in epilepsy patients presenting at the Emergency Department with complaints of an epileptic seizure, and to thus evaluate the utility of this biomarker in the differentiation of epilepsy and PNES patients from each other.The study included patients aged18 years who had experienced an epileptic seizure or were experiencing an epileptic seizure proven with EEG. All patients with brain disease of structural or infectious cause were excluded from the study (dementia, stroke, intracranial mass, meningitis, encephalitis, Creutzfeldt-Jacobs disease, abscess, etc). Patients were also excluded if they had traumatic brain injury or a severe systemic disease such as sepsis, which was thought to impair brain blood flow. The control group was formed of completely healthy volunteers.Evaluation was made of a total of 49 patients, comprising 19 (38.78%) males and 30 (61.22%) females, and a control group of 53 healthy volunteers comprising 28 (52.83%) males and 25 (47.17%) females. The serum neurogranin value was median 184.16 ng/dl (range: 110.1-1172.98) in the patient group and 97.90 ng/dl (range: 73.71-282. 11) in the control group. The serum neurogranin value was determined to be statistically significantly higher in the patient group than in the control group (p0.005).The differential diagnosis of ES from PNES remains a challenging situation for emergency service physicians. Based on the findings of this study, it can be said that the serum NRGN level is high in patients who have experienced an epileptic seizure. Therefore, this new biomarker can be considered for use in the differential diagnosis of epileptic seizure and PNES. |
