    Evaluation of Choroidal Thickness Using Spectral-Domain Optical Coherence Tomography in Patients with Migraine: A Comparative Study
    (2015) Karalezli, Aylin; Celik, Guner; Koktekir, Bengu Ekinci; Kucukerdonmez, Cem; 25633615; GOE-6067-2022; HTO-3612-2023
    Purpose: To assess choroidal thickness in patients with migraine and compare them with healthy controls, using spectral-domain optical coherence tomography (OCT). Methods: In this prospective case-control study, choroidal thicknesses of 20 newly diagnosed migraine patients and 20 age-and sex-matched healthy subjects were measured using a high-speed, high-resolution frequency domain (FD) OCT device (lambda = 840 nm, 26.000 A-scans/s, 5 mu m axial resolution). All patients underwent a complete ophthalmic examination before the measurements. OCT measurements were taken at the same time of day (9: 00 AM), in order to minimize the effects of diurnal variation. Results: There was a statistically significant difference in median choroidal thickness between the migraine patients (277.00 [interquartile range (IQR) 85.75] mu m) and controls (301.00 [IQR 90.50] mu m) (p = 0.012). There were significant differences at all measurement points (p<0.05 for all). Conclusions: The decreased choroidal thickness of patients with migraine might be related to the vascular pathology of the disease. Further studies are needed to evaluate the etiopathologic relationship between choroidal thickness and migraine.

    Topiramate-Induced Changes in Anterior Chamber Angle and Choroidal Thickness
    (2016) Karalezli, Aylin; Koktekir, Bengu Ekinci; Celik, Guner; 26020486; GOE-6067-2022
    Purpose: To investigate the acute effects of topiramate on the anterior chamber angle (ACA) and choroidal thickness in patients with migraine. Methods: This prospective study included 15 eyes of 15 patients with migraine who have been scheduled to start topiramate therapy. All patients underwent complete ophthalmic examination including measurement of the ACA and choroidal thickness using a spectral domain optical coherence tomography device (Optovue Inc.) and refractive status evaluation with an autorefractokeratometer (KR-8100; Topcon) at the baseline and 1 week after starting therapy. The patients were asked to report any pain or discomfort in their eyes during therapy at the follow-up visit. Results: None of the patients experienced pain or discomfort in their eyes. The mean ACA significantly decreased at the first week of the therapy compared with the baseline levels (40.34 +/- 7.06 degrees and 36.89 +/- 6.87 degrees, respectively) (P=0.001). However, the mean choroidal thickness increased from 277.33 +/- 95.60 mu m at the baseline to 323.40 +/- 84.50 mu m at the first week (P=0.01). There was a nonsignificant increase in the mean refractive error (from -0.25 +/- 0.54 diopter [D] at the baseline to -0.38 +/- 0.49 D after 1 week) (P=0.06). Conclusions: Topiramate can acutely decrease the ACA and increase the choroidal thickness. Because these effects may be asymptomatic, patients with migraine who start this therapy should be warned to be closely followed up by an ophthalmologist.

    Evaluation of Carotid Intima-Media Thickness in Children with Migraine: A Marker of Subclinical Atherosclerosis
    (2016) Poyrazoglu, Hatice Gamze; Vurdem, Umit Erkan; Arslan, Alev; Uytun, Salih; https://orcid.org/0000-0003-4444-0027; 27371188; V-1112-2019
    Migraine is a commonly seen neurovascular disorder during childhood. Inflammation induced by the activation of cytokines and neuropeptides is implied in its pathophysiology. There is an association between inflammation and atherosclerosis in patients with migraine. In addition, there is a strong correlation between early atherosclerotic wall lesions and carotid intima-media thickness (CIMT). The study population consisted of 57 migraine patients aged 5-17 years, as well as 47 healthy children who served as the control group. Those migraine patients who were not receiving any medications at the interictal period were compared to healthy controls in terms of their measured lipid levels, thyroid function, vitamin B12 levels, serum iron levels, iron binding capacity, complete blood count, C-reactive protein (CRP) levels, and carotid intima-media thickness (CIMT) scores, which may comprise risk factors for atherosclerosis. When children in the migraine and control groups were compared in terms of those risk factors that are known to be related to vascular changes, no significant differences were found. However, a significant difference was detected in CIMT values (P < 0.05). Atherosclerosis commences in childhood, and there is a long period of time before the onset of ischemic symptoms occurs. In children with migraine, an evaluation of CIMT can be used as a non-invasive imaging modality to detect atherosclerosis, which develops in the context of chronic inflammation. In this way, measures to reduce morbidity and mortality, which may result from cardiovascular diseases, can be implemented.

    (2018) Iyigundogdu, Ilkin; Derle, Eda; Asena, Leyla; Kural, Feride; Kibaroglu, Seda; Ocal, Ruhsen; Akkoyun, Imren; Can, Ufuk; 0000-0001-7860-040X; 0000-0003-2122-1016; 0000-0002-6848-203X; 0000-0002-4226-4034; 0000-0002-3964-268X; 0000-0002-2860-7424; 0000-0001-8689-417X; 28952336; AAJ-2053-2021; AAI-8830-2021; E-5914-2016; AAL-9808-2021; AAJ-2956-2021; V-3553-2017; AAK-7713-2021; AAJ-2999-2021
    Aim To compare the relationship between white matter hyperintensities (WMH) on brain magnetic resonance imaging and retinal nerve fiber layer (RNFL), choroid, and ganglion cell layer (GCL) thicknesses in migraine patients and healthy subjects. We also assessed the role of cerebral hypoperfusion in the formation of these WMH lesions. Methods We enrolled 35 migraine patients without WMH, 37 migraine patients with WMH, and 37 healthy control subjects examined in the Neurology outpatient clinic of our tertiary center from May to December 2015. RFNL, choroid, and GCL thicknesses were measured by optic coherence tomography. Results There were no differences in the RFNL, choroid, or GCL thicknesses between migraine patients with and without WMH (p>0.05). Choroid layer thicknesses were significantly lower in migraine patients compared to control subjects (p<0.05), while there were no differences in RFNL and GCL thicknesses (p>0.05). Conclusions The only cerebral hypoperfusion' theory was insufficient to explain the pathophysiology of WMH lesions in migraine patients. In addition, the thinning of the choroid thicknesses in migraine patients suggests a potential causative role for cerebral hypoperfusion and decreased perfusion pressure of the choroid layer.

    Objective: Attention deficit and hyperactivity disorder (ADHD) is a neuro-developmental disorder related to internalizing and externalizing disorders as well as somatic complaints and disorders. This study was conducted to evaluate the prevalence of headache subtypes, epilepsy, atopic disorders, motion sickness and recurrent abdominal pain among children and adolescents with ADHD and their parents. Methods: In a multi-center, cross-sectional, familial association study using case-control design, treatment na ve children and adolescents between 6 and 18 years of age diagnosed with ADHD according to the DSM-5 criteria as well as age- and gender matched healthy controls and their parents were evaluated by a neurologist and analyzed accordingly. Results: 117 children and adolescents with ADHD and 111 controls were included. Headache disorder diagnosis was common for both patients and healthy controls (59.0% vs. 37.8%), with a significantly elevated rate in the ADHD group (p = 0.002). Migraine was found in 26.0% of ADHD patients and 9.9% of healthy controls. Tension headache was found in 32.4% of ADHD patients and 27.9% of healthy controls. Headache diagnosis was also found to be significantly more common in mothers of children with ADHD than control group mothers (90.5% vs. 36.6%, p < 0.001). Conclusion: Headache diagnoses and specifically migraines were significantly more common among children with ADHD and their mothers, while recurrent abdominal pain was elevated in both parents and ADHD patients. Migraine is an important part of ADHD comorbidity, not only for children but also for mothers. Motion sickness may be reduced among families of ADHD probands.

    Early Maladaptive Schemas Differing According To Sex May Contribute To Migraine Among The Youth
    (2022) Aksu, Gullen Guller; Kayar, Ozan; Tufan, Ali Evren; Kultulk, Meryem Ozlem; Sucu, Damla Hazal; Tasdelen, Bahar; Toros, Fevziye; Olzge, Aynur; 35459526
    Objective: Despite many diverse findings from studies about the comorbidity of psychiatric disorders and migraine, there are still unknown points. Schemas, which are the basic structures of cognition, are understudied. This study examined the effects of sex on early maladaptive schemas (EMSs) and the clinical characteristics of migraine in adolescents with migraine.Methods: The sample comprised 171 adolescents (67.3% females, n = 115) aged 12-18 years. The clinical characteristics of migraine (duration, severity, frequency of headaches, etc.), accompanying symptoms (nausea, vomiting, photophobia, etc.) and EMSs were evaluated depending on sex. Psychopathology and abuse history were analyzed as covariates in this study.Results: The mean age was 15.4 +/- 1.9 among the females and 15.2 +/- 2.0 among the males (p = 0.65). There was no difference in terms of migraine characteristics, and except for dizziness and pain relief by massage, all other symptoms were similar between the sexes. Female adolescent migraineurs significantly elevated scores for EMS of emotional deprivation, abandonment/instability, defectiveness/shame (disconnection/rejection domain), dependence/incompetence, vulnerability to harm/illness, failure (in impaired autonomy/performance domain) and negativity/pessimism (in hypervigilance/inhibition domain). On the other hand, male migraineurs had significantly elevated scores only in insufficient self-control/self-discipline (in impaired limits domain). Type of migraine and current psychopathology had no significant effect on the EMS domains, while sexual abuse history significantly affected some EMS.Conclusion: Our study highlights the importance of screening for EMSs among adolescent patients with migraine. Schema therapy and similar therapeutic interventions may be used in the management of migraine in adolescents. Gender may also be important (c) 2022 Published by Elsevier B.V. on behalf of The Japanese Society of Child Neurology.

    Retinal vascular density evaluation of migraine patients with and without aura and association with white matter hyperintensities
    (2019) Ulusoy, Mahmut Oguz; Horosanli, Bahriye; Kal, Ali; 30762208
    Underlying pathophysiological mechanism of migraine is not all clear; however, recent reports suggested that neurovascular system is involved. We aimed to evaluate the retinal vessel densities of migraine patients with and without aura and the associations with white matter hyperintensities (WMH), using optical coherence tomography angiography (OCTA). We recruited 28 migraine with aura (MWA) patients, 26 migraine without aura (MWO) and age and sex-matched 34 healthy controls in our study. All participants were evaluated with optical coherence tomography (OCT) and OCTA for optic nerve parameters and retinal vessel densities with RTVue XR AVANTI. On macular OCTA, superficial and deeper retinal foveal vessel density (VD) were significantly lesser in MWA and MWO than controls. On optic nerve OCTA, whole optic disc, peripapillary, superior hemisphere, superior layer and temporal layer VD were significantly lesser in MWA and MWO. In group of MWA with the WMH, deeper foveal VD and superior hemisphere VD, average RNFL, superior hemisphere and superior layer were significantly lesser and also foveal avascular zone was significantly larger than the group of without WMH. Alterations of VD in patients with migraine are showed in our study. In addition, in group of MWA these alterations have associations with WMH. Supporting these findings with further reports can be useful to understand the pathophysiology of this disease.
