Comparative Study[Behavioral dependence on analgesics in medication overuse headache].
Authors conducted a clinical and psychological study in 3 groups of patients: 43 patients with medication overuse headache (MOH), 23 patients with chronic headache without medication overuse and 14 patients with episodic migraine. Along with clinical and neurological examination, the following questionnaires were administered: the McGill questionnaire, the Beck Depression Inventory, the Spielberger-Khanin test, the Toronto alexithymia scale, the Leonhard personality inventory and an inventory based on the Benzodiazepine Dependence Self-Report Questionnaire (BDSRQ). ⋯ It was identified a progressive disease course with a formation of a specific behavioral pattern. Further studies are warranted to understand the reasons for acquiring behavioral dependence on analgetic medications, to improve management and prevent relapses of medication overuse headache.

[Vertebral artery dissection: peculiarities of clinical and magnetic resonance imaging manifestations].
The aim of this study was to analyze clinical and neuroimaging manifestations of vertebral artery (VA) dissection. Twenty seven patients (19 men, 8 women, mean age 34.1±6.1) with the VA dissection were enrolled. All the patients underwent MRA, neck MRI (T1 f-s, T2 f-s) and head MRI. ⋯ Clinical manifestations of VA dissection depend on the IMH localization. The main mechanism of brain ischemia appears to be an arterial embolism by clotted IMH fragments from the secondary intimal tear. It is suggested that in patients with isolated pain, the media may be weaker than in patients with brain ischemia that in turn promotes subadventicial IMH propagation.
