Cranial autonomic symptoms: prevalence, phenotype and laterality in migraine and two potentially new symptoms (original) (raw)
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%...

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...

Objectives. Migraine is a prevalent debilitating neurological disorder manifested by frequent episodes of pounding headache. Cranial autonomic symptoms are frequently reported in patients of trigeminal autonomic cephalgias, but various studies also documented these cranio-autonomic symptoms in migraine patients as well. The primary objective of our study is to evaluate the prevalence of cranio-autonomic symptoms (CAS) amongst the patients suffering from migraines. Material and methods. This study was conducted as a descriptive, cross-sectional survey involving patients attending the neurology clinic at Dow University Hospital. 132 patients met the inclusion criteria (according to ICHDIII) and were assessed for the frequency of cranio-autonomic symptoms. Outcomes. The mean age recorded was 26.37 ± 6.31 years, while the mean duration of diagnosis was 23.54 ± 16.52 months. The frequency of cranio-autonomic symptoms was observed among 55% of the patients suffering from migraines in our ...

Introduction: The presence of cranial autonomic symptoms (CAS) is a hallmark of trigeminal autonomic cephalalgia like cluster headache but their presence in migraine is also not uncommon. Like in trigeminal autonomic cephalalgias, the activation of the trigeminal autonomic reflex pathway is thought to be the possible explanation of the presence of cranial autonomic symptoms in migraine also. Previous studies suggested that around half of the patients of migraine suffer from these symptoms. The aim of our study was to observe the frequency of cranial autonomic symptoms in episodic migraine patients along with their clinical and autonomic characteristics. Methods and Materials: Fifty patients of episodic migraine attending the headache clinic of Dr. RMLIMS, Lucknow and fulfilling the diagnostic criteria of International classification of headache disorder third edition beta were randomly selected and enrolled in the study. The detailed interview regarding presence of cranial autonomic...
