Abstract
The utility of the differences between cluster headache (CH) and paroxysmal hemicrania (PH) is limited by the considerable overlap of their clinical characteristics. We compared 54 patients with CH and eight patients with PH in terms of demographic features, characteristics of headache attacks, associated autonomic features, temporal forms of disorders, and response to verapamil. According to our results, clinical features that distinguished CH and PH patients were: maximal pain localization, ocular in CH patients and extra-ocular in PH group; mean attack duration was longer and mean attack frequency was lower in CH patients in comparison with PH patients. Conjuctival injection was the only autonomic sign seen more frequently in CH patients. There were more CH patients with episodic and more PH patients with unremitting form of the disorder in examined groups. Although statistical analysis pointed out a significant difference between these clinical features, there was no clinical characteristic that exclusively belonged to one of these headache entities. Demographic characteristics (age, gender, social background), the other headache attack features (nocturnal attacks, interattack tenderness), the other autonomic signs, as well as the response to verapamil did not differ significantly between two groups.

Abstract
We present a prospective study of 240 patients with medication overuse headache (MOH) treated with drug withdrawal and prophylactic medications. At 1-year follow-up, 137 (57.1%) patients were without chronic headache and without medication overuse, eight (3.3%) patients did not improve after withdrawal and 95 (39.6%) relapsed developing recurrent overuse. Age at time of MOH diagnosis, regular use of benzodiazepines, frequency and Migraine Disability Assessment (MIDAS) score of chronic headache, age at onset of primary headache, frequency and MIDAS score of primary headache, ergotamine compound overuse and daily drug intake were significantly different between successfully and unsuccessfully treated patients. Multivariate analysis determined the frequency of primary headache disorder, ergotamine overuse and disability of chronic headache estimated by MIDAS as independent predictors of treatment efficacy at 1-year follow-up.

Do interictal microembolic signals play a role in higher cortical dysfunction during migraine aura? Cephalalgia 2015; 36:561-7. [DOI: 10.1177/0333102415607191] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2015] [Accepted: 07/09/2015] [Indexed: 01/03/2023]
Abstract
Introduction The aim of this study was to evaluate the prevalence and clinical impact of interictal microembolic signals (MES) in patients suffering from migraine with higher cortical dysfunction (HCD), such as language and memory impairment, during an aura. Patients and methods This study was carried out on 34 migraineurs with language and memory impairment during aura (HCD group), 31 migraineurs with only visual or visual and somatosensory symptoms during aura (Control group I), and 34 healthy controls (Control group II). We used a Doppler instrument to detect microemboli. Demographic data, disease features and the detection of MES between these groups, as well as the predictors of HCD during the aura, were analyzed. Results The duration of aura was longer and the frequency of aura was higher among patients with language and memory impairment during aura compared to Control group I. MES was detected in 29.4% patients from the HCD group, which was significantly higher compared to 3.2% in Control group I and 5.9% in Control group II. Regarding the absence or presence of MES, demographic and aura features were not different in the HCD subgroups. A longer duration of aura, the presence of somatosensory symptoms during the aura and the presence of interictal MES were independent predictors of HCD during the aura. Conclusion The present findings indicate that HCD and MES are related in patients with migraine with aura. Further research is needed to better understand the exact pathophysiological mechanism.
