Diagnosis of comorbid migraine without aura in patients with idiopathic/genetic epilepsy based on the gray zone approach to the International Classification of Headache Disorders 3 criteria

BackgroundMigraine without aura (MwoA) is a very frequent and remarkable comorbidity in patients with idiopathic/genetic epilepsy (I/GE). Frequently in clinical practice, diagnosis of MwoA may be challenging despite the guidance of current diagnostic criteria of the International Classification of Headache Disorders 3 (ICHD-3). In this study, we aimed to disclose the diagnostic gaps in the diagnosis of comorbid MwoA, using a zone concept, in patients with I/GEs with headaches who were diagnosed by an experienced headache expert.MethodsIn this multicenter study including 809 consecutive patients with a diagnosis of I/GE with or without headache, 163 patients who were diagnosed by an experienced headache expert as having a comorbid MwoA were reevaluated. Eligible patients were divided into three subgroups, namely, full diagnosis, zone I, and zone II according to their status of fulfilling the ICHD-3 criteria. A Classification and Regression Tree (CART) analysis was performed to bring out the meaningful predictors when evaluating patients with I/GEs for MwoA comorbidity, using the variables that were significant in the univariate analysis.ResultsLonger headache duration (<4 h) followed by throbbing pain, higher visual analog scale (VAS) scores, increase of pain by physical activity, nausea/vomiting, and photophobia and/or phonophobia are the main distinguishing clinical characteristics of comorbid MwoA in patients with I/GE, for being classified in the full diagnosis group. Despite being not a part of the main ICHD-3 criteria, the presence of associated symptoms mainly osmophobia and also vertigo/dizziness had the distinguishing capability of being classified into zone subgroups. The most common epilepsy syndromes fulfilling full diagnosis criteria (n = 62) in the CART analysis were 48.39% Juvenile myoclonic epilepsy followed by 25.81% epilepsy with generalized tonic-clonic seizures alone.ConclusionLonger headache duration, throbbing pain, increase of pain by physical activity, photophobia and/or phonophobia, presence of vertigo/dizziness, osmophobia, and higher VAS scores are the main supportive associated factors when applying the ICHD-3 criteria for the comorbid MwoA diagnosis in patients with I/GEs. Evaluating these characteristics could be helpful to close the diagnostic gaps in everyday clinical practice and fasten the diagnostic process of comorbid MwoA in patients with I/GEs

Evaluation of Visual Evoked Potentials Normative Values: An Electroneurophysiology Laboratory Experience

Aim: To determine and compare gender and age-based normative P100 latency and amplitude values in our laboratory.Materials and Methods: 100 adults (75 female+25 male) were included in the study. VEP pattern was performed to both eyes, separately to each one. P100 latencies and amplitudes were compared between the two eyes in terms of gender and age.Results: The ages of the participants were between 10.18 and 64.47 and the mean age was 39.07 ± 12.57 years. The average of latency determined in females was 107.15 ± 4.56 in the right and 108.12 ± 4.6 in the left, in males was 110.2 ± 4.78 in the right and 111.76 ± 4.47 in the left. Bilateral P100 latencies were detected longer in males. The amplitude values were 9.09 ± 5.05 in females and 7.32 ± 2.48 in males. There was a statistically negative significant correlation between amplitude measurements in the right eyes (r: - 0.337; p 0.05).Conclusion: Amplitude decreased with increasing age in females, but no significant differences were found in latencies. There was not detected differences on latency and amplitude values in males with increasing age. Latencies in male were found to be longer when compared to female. It is thought that determination of community-based laboratory norms is important in evaluating the results and revealing normal values is also valuable

The effect of sleep disorders on quality of life in patients with epilepsy: A multicenter study from Turkey

Objective: We aimed to investigate sleep disorders in patients with epilepsy (PWE) and to investigate the effects of sleep disorders on quality of life. Methods: In our multicenter study conducted in Turkey, 1358 PWE were evaluated. The demographic and clinical data of the patients were recorded. The Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), and Quality of Life in Epilepsy Inventory-10 (QOLIE-10) were administered. Results: The mean age of 1358 patients was 35.92 ± 14.11 (range, 18–89) years. Seven hundred fifty-one (55.30 %) were women. Some 12.7 % of the patients had insomnia (ISI > 14), 9.6 % had excessive daytime sleepiness (ESS > 10), 46.5 % had poor sleep quality (PSQI > 5), and 354 patients (26.1 %) had depressive symptoms (BDI > 16). The mean QOLIE-10 score was 22.82 ± 8.14 (10–48). Resistant epilepsy was evaluated as the parameter with the highest risk affecting quality of life Adjusted odds ratio (AOR = 3.714; 95 % confidence interval (CI): [2.440–5.652] < 0.001)). ISI (AOR = 1.184; 95 % CI: [1.128–1.243]; p < 0.001), ESS (AOR = 1.081; 95 % CI: [1.034–1.130]; p < 0.001), PSQI (AOR = 0.928; 95 % CI: [0.867 – 0.994]; p = 0.034), BDI (AOR = 1.106; 95 % CI: [1.084–1.129]; p < 0.001), epilepsy duration (AOR = 1.023; 95 % CI: [1.004–1.041]; p = 0.014), were determined as factors affecting quality of life. Significance: Sleep disorders are common in PWE and impair their quality of life. Quality of life can be improved by controlling the factors that may cause sleep disorders such as good seizure control, avoiding polypharmacy, and correcting the underlying mood disorders in patients with epilepsy
