Differences in brainstem volume between migraineurs and healthy controls have been demonstrated in previous research, nevertheless, the effect of migraine aura on brainstem volume is still uncertain. The aim of this study was to investigate the brainstem volume in migraineurs and examine the effect of migraine aura on brainstem volume.Our study included 90 female migraine patients without white matter lesions. (29 migraine patients with aura (MwA) and 61 migraine patients without aura (MwoA) and 32 age-matched female healthy controls (HC). Using the FreeSurfer image analysis suite, the volumes of the entire brainstem and its subfields (medulla, pons, and midbrain) were measured and compared between migraine subgroups (MwA vs. MwoA) and the healthy control group. The possible effects of migraine characteristics (i.e., disease duration and migraine attack frequency) on brainstem volume were also investigated.Migraineurs had greater medulla volume (MwoA 3552 ± 459 mm3, MwA 3424 ± 448 mm3) than healthy controls (3236 ± 411 mm3). Statistically, MwA vs. HC p = 0.040, MwoA vs. HC p = 0.002, MwA vs. MwoA p = 0.555. A significant positive correlation was found between disease duration and the volume of medulla in the whole migraine group (r = 0.334, p = 0.001). Neither the whole brainstem nor its subfields were significantly different in volume between migraine subgroups.Brainstem volume changes in migraine are mainly localized to the medulla and not specific to the presence of aura.}, keywords = {morphometry; Magnetic Resonance Imaging; AURA; EPISODIC MIGRAINE; Brainstem volume}, year = {2024}, eissn = {1872-6968} } @article{MTMT:34207248, title = {The volume of the thalamus and hippocampus in a right-handed female episodic migraine group}, url = {https://m2.mtmt.hu/api/publication/34207248}, author = {He, Mingchen and Kis-Jakab, Gréta and Komáromy, Hedvig and Perlaki, Gábor and Orsi, Gergely and Bosnyák, Edit and Rozgonyi, Renáta and John, Flóra and Trauninger, Anita and Eklicsné Lepenye, Katalin and Pfund, Zoltán}, doi = {10.3389/fneur.2023.1254628}, journal-iso = {FRONT NEUR}, journal = {FRONTIERS IN NEUROLOGY}, volume = {14}, unique-id = {34207248}, issn = {1664-2295}, year = {2023}, eissn = {1664-2295} } @{MTMT:33126566, title = {Képalkotó diagnosztika alkalmazása a rehabilitációs ellátásban}, url = {https://m2.mtmt.hu/api/publication/33126566}, author = {Nagy, Judit and Komáromy, Hedvig}, booktitle = {A rehabilitációs és fizikális medicina módszertana}, unique-id = {33126566}, year = {2023}, pages = {209-230} } @article{MTMT:33032134, title = {Age-related decline in circulating IGF-1 associates with impaired neurovascular coupling responses in older adults.}, url = {https://m2.mtmt.hu/api/publication/33032134}, author = {Tóth, Luca and Czigler, András and Hegedüs, Emőke and Komáromy, Hedvig and Amrein, Krisztina and Czeiter, Endre and Yabluchanskiy, Andriy and Koller, Ákos and Orsi, Gergely and Perlaki, Gábor and Schwarcz, Attila and Büki, András and Ungvári, Zoltán István and Tóth, Péter József}, doi = {10.1007/s11357-022-00623-2}, journal-iso = {GEROSCIENCE}, journal = {GEROSCIENCE: OFFICIAL JOURNAL OF THE AMERICAN AGING ASSOCIATION (AGE)}, volume = {44}, unique-id = {33032134}, issn = {2509-2715}, abstract = {Impairment of moment-to-moment adjustment of cerebral blood flow (CBF) to the increased oxygen and energy requirements of active brain regions via neurovascular coupling (NVC) contributes to the genesis of age-related cognitive impairment. Aging is associated with marked deficiency in the vasoprotective hormone insulin-like growth factor-1 (IGF-1). Preclinical studies on animal models of aging suggest that circulating IGF-1 deficiency is causally linked to impairment of NVC responses. The present study was designed to test the hypotheses that decreases in circulating IGF-1 levels in older adults also predict the magnitude of age-related decline of NVC responses. In a single-center cross-sectional study, we enrolled healthy young (n = 31, 11 female, 20 male, mean age: 28.4 + / - 4.2 years) and aged volunteers (n = 32, 18 female, 14 male, mean age: 67.9 + / - 4.1 years). Serum IGF-1 level, basal CBF (phase contrast magnetic resonance imaging (MRI)), and NVC responses during the trail making task (with transcranial Doppler sonography) were assessed. We found that circulating IGF-1 levels were significantly decreased with age and associated with decreased basal CBF. Age-related decline in IGF-1 levels predicted the magnitude of age-related decline in NVC responses. In conclusion, our study provides additional evidence in support of the concept that age-related circulating IGF-1 deficiency contributes to neurovascular aging, impairing CBF and functional hyperemia in older adults.}, keywords = {Aging; cognitive decline; VCI; VCID; Vascular cognitive impairment; neurovascular uncoupling}, year = {2022}, eissn = {2509-2723}, pages = {2771-2783}, orcid-numbers = {Czeiter, Endre/0000-0002-9578-6944; Koller, Ákos/0000-0003-3256-8701; Ungvári, Zoltán István/0000-0002-6035-6039} } @article{MTMT:32070948, title = {Krónikus dialízis kapcsán kialakult destruktív cervicalis spondylarthropathia esete}, url = {https://m2.mtmt.hu/api/publication/32070948}, author = {Berta, Balázs and Komáromy, Hedvig and Schwarcz, Attila and Kajtár, Béla and Büki, András and Kuncz, Ádám}, doi = {10.18071/isz.74.0211}, journal-iso = {IDEGGYOGY SZEMLE}, journal = {IDEGGYOGYASZATI SZEMLE / CLINICAL NEUROSCIENCE}, volume = {74}, unique-id = {32070948}, issn = {0019-1442}, abstract = {A case of a 61-year-old male patient suffered chronic renal failure and dialysed for 23 years with destructive cervical spondylarthropathy is presented. The patient presented with sudden onset of cervical pain radiating into his shoulders without neurological deficits. CT and MRI of the cervical and thoracic spine revealed severe destructive changes and compressive fractures of C6 and C7 vertebrae which caused the narrowing of the nerve root canals at these levels. A 360-degree fixation was performed to treat the unstable fracture and the patient's pain (C6 and C7 corpectomy, autolog bone graft replacement of the two vertebral bodies, anterior plate fixation and posterior instrumentation with screws and rods). Postoperatively the patient had no significant pain, no neurological deficit and he was able to manage independent life himself. During the immediate follow-up CT of the neck showed the satisfactory position of the bone graft and the metal implantations. The 6 months follow-up CT revealed the anterior migration of the two screws from the Th1 vertebral body and 2 mm ventral elevation of the caudal end of the plate from the anterior surface of the Th1 vertebral body. The 1-year follow-up could not be performed because the patient died due to cardio-pulmonary insufficiency. This is the second Hungarian report of a chronic dialysis related severe spondylarthropathy which may cause pathologic fractures of the vertebral bodies. The typical radiological and histological findings are discussed. This disease affect patients' quality of life and the conservative treatment alone seems to be ineffective in most cases.

The aim of this study was to investigate migraine patients with or without WMLs to see the effects of these tissue damages on cortical thickness and volume. The role of migraine characteristics (duration of headache, attack frequency, estimated lifetime attack number, aura) was also tested.As study participants, 161 female migraine patients (63 with aura; 52 with WMLs) and 40 age-matched healthy female subjects were enrolled in the study. None of the included migraine patients' headache or aura (where present) was unilaterally side-locked. Patients and controls were all right handed. Except for migraine, patients were free of any medical comorbidity. Cortical reconstruction and segmentation were performed on the 3D T1-weighted images using Freesurfer 5.3 image analysis suite. The automatic cortical parcellation was based on Freesurfer's Desikan-Killiany-Tourville atlas, which has 31 cortical regions per hemisphere. The segmented regions were divided into five lobes (frontal, parietal, temporal, occipital, insula). Since the left and right differences in lobar and insular volumes/thicknesses were not different among our groups, volume and cortical thickness were calculated for corresponding bilateral lobes.There was no significant difference in age between the whole migraine and the control groups. Migraineurs with WMLs (L+ patients) were significantly older than lesion-free (L-) patients (P = 0.0003) and controls (P = 0.018). Disease duration (P = 0.003), the total number of migraine attacks (P = 0.022) and the rate of aura (P = 0.0003) were significantly higher in L+ patients than in L- patients. Cortical thickness and volume measurements of lobes were not statistically different between the three groups (L+, L-, control). Age showed a significant negative association with both thickness and volume in each examined lobe (P < 0.001). Intracranial volume (ICV) showed a significant positive association with all regional volumes (P < 0.001). There were no significant group*age, group*ICV, or age*ICV interactions. None of the migraine characteristics were selected by stepwise linear regression as significant predictors of cortical thickness or volume. Only age (for both thickness and volume) and ICV (for volume) were identified as significant predictors (P < 0.001). When the L + group was divided into two subgroups by median split of total and lobar lesion number and volume, the cortical measures did not show any significant difference between the groups with low vs. high lesion number/volume by stepwise linear regression.In a female migraine group, we found that the WMLs and clinical migraine characteristics have no effect on cortical thickness and volume of bilateral lobes. Lobar cortical thicknesses were equivalent within the range of ±0.1 mm. Only age and ICV proved to be significant predictors; the former for both cortical thickness and volume, while the latter for cortical volume.}, keywords = {AGE; Magnetic Resonance Imaging; Cortical reconstruction and segmentation; Intracranial volume; Lobar cortical thickness and volume; Migraine headache characteristics; Migraine-related intracerebral white matter lesions}, year = {2019}, eissn = {1129-2377}, orcid-numbers = {Nagy, Szilvia Anett/0000-0001-6483-9209} }
