Brain structural abnormalities in migraine patients: an observational study
Background: Migraine is a common neurological disorder, characterized by a complex physiopathology. We analyzed brain structural differences in migraine and the possible pathogenetic mechanism underlying this disease.Methods: We assessed brain structure in migraine patients, 14 with aura (MA) and 14 migraine without aura, (MO) compared with health subjects (HS) by using (VBM) approach.Results: Total cerebral GMV showed a significant difference between MA and HS (p=0.03), and between MO and HS (p=0.003). In addition, there was a significative difference trend between MA and MO (p=0.05) groups. We found three clusters of regions which showed significant GMV reduction in MA compared with MO. MA subjects showed a decrease of GMV in 4 clusters if compared with HS, and MO subjects showed a decrease of GMV in 3 clusters if compared with HS. We observed that MA and MO patients had a significant reduction of GMV in the frontal and temporal lobe and the cerebellum, if compared to HS. The bila...
BackgroundWhilst cranial autonomic symptoms (CAS) are typically associated with the trigeminal autonomic cephalalgias (TAC’s), they have also been reported in migraine. Identification and understanding of these symptoms in migraine is important to ensure timely diagnosis and effective management. MethodsMigraineurs seen within our tertiary headache service between 2014-2018 ( n =340): cohort one, and a separate cohort of headache patients seen between 2014-May 2021 reporting voice change and/or throat swelling as CAS were selected ( n =64); cohort two. We examined, as a service evaluation, our records regarding age, sex, diagnosis, headache and CAS frequency and laterality as acquired from the first consultation, during which a detailed headache history is taken by a trained physician. ResultsCohort 1: Mean age 43 (range 14-94, SD 15). The most common diagnosis was chronic migraine (78%). Median monthly headache frequency was 26 days (IQR 15-75). At least one CAS was reported in 74%...
Cranial autonomic symptoms in episodic and chronic migraine: a cross sectional study in Iran
BMC Neurology, 2021
Background Cranial autonomic symptoms are common in migraine, with eye redness and tearing being the most common ones. Their identification can help to avoid misdiagnosis, predict the disease course, and select the appropriate treatment. Methods This was a cross-sectional study of 904 patients who presented with migraine to a headache referral clinic. The participants filled out a questionnaire about their headache characteristics, as well as the presence of cranial autonomic symptoms. A total of 904 patients, 698 women (77.2%) and 206 men (22.8%), were included in the study, with a mean (SD) age of 38.05 (11.76) years. Results About 70% of subjects with chronic migraine and 56.2% of those with episodic migraine reported one or more cranial autonomic symptoms. The two most commonly reported autonomic symptoms were eye redness (36.06%) and tearing (21.02%). Chronic migraine (43.4% vs. 29.5%), unilateral headache (56.8% vs. 48.7%), and blurred vision (20% vs. 14.7%) were significantly...

Background People with migraine have localised (i.e., cephalic) mechanical sensitivity. There is uncertainty regarding widespread (i.e., extra-cephalic) mechanical sensitivity and variations in mechanical sensitivity throughout the migraine cycle. Therefore, this study aimed (1) to comprehensively assess mechanical sensitivity in both cephalic and extra-cephalic regions during the preictal, ictal, postictal and interictal phases; and (2) to compare these findings with mechanical sensitivity at corresponding time-points and locations in healthy participants. Methods According to sample size calculations, 19 people with migraine and 19 matched healthy volunteers participated in a prospective longitudinal study. Pressure pain thresholds were evaluated in three cephalic regions (temporalis, upper trapezius and C1 paraspinal muscles) and two extra-cephalic regions (extensor carpi radialis and tibialis anterior muscle) with a digital algometer during the four phases of the migraine cycle ...
