Filter by:Concussion is defined as any temporary disturbance in brain function following a blow to the head. It may not involve a loss of consciousness and usually results in a post concussive headache (PCH) immediately after the injury. Between 30 and 50 percent of patients with concussion will develop postconcussive syndrome (PCS) consisting of symptoms such as headache, and a variety of other debilitating symptoms lasting several weeks to months. The objective of this study is to determine if metoclopramide, a drug commonly used in the treatment of migraine headache, will be effective in relieving PCH and in preventing PCS. Eligible patients will have a history of a concussion resulting in headache within the past 24 hours. Patients will rate their pain on a standard scale before and after being treated with one or two intravenous doses of either metoclopramide or saltwater placebo. They will be contacted by telephone 1, 4 and 8 weeks later in order to determine if they have developed the postconcussive syndrome.
Most patients with CPTH present with additional major cognitive, behavioral and somatic problems. Most drugs used currently have a negative influence on cognition. Therefore, treatment strategies addressing both the headache and cognitive disturbances in patients with CPTH are necessary. (CPTH; Chronic Post Traumatic Headache).
The release of the neuropeptide calcitonin gene-related peptide (CGRP) is thought to play a causative role in migraine. Nociceptin immunoreactivity and ORL-1 mRNA have been detected in human trigeminal ganglia where it was co-localized with CGRP. It may play a role in migraine pathogenesis. We are collecting the blood samples of migraineurs for analysis of these neuropeptides.
Angiographies of the supra-aortic vessels by magnetic imaging have become common recently. So it was the purpose of this study to evaluate the imaging potential of different contrast agents. Three contrast agents for magnetic resonance imaging are compared in angiographies of the supra-aortic arteries in a intraindividual study of 10 patients. All applications of these contrast agents are performed with a flow of 2 ml/s. One contrast medium is applicated a second time with a reduced flow of 1 ml/s. The angiographies of the supra-aortic vessels are evaluated by two experienced readers in a consensus reading. The signal/noise- and contrast/noise-ratio of anatomic vessel segments of the carotic and vertebral arteries are measured and compared to each other.
