Active clinical trials for "Headache"

This is a research study examining cutaneous allodynia and cluster headaches. Cutaneous allodynia means the feeling of pain or unpleasant sensation when normally non-painful stimuli (e.g. light touch) are applied to the skin. Many studies have been performed looking at the presence of cutaneous allodynia in patients with migraines; however, few studies have examined it in cluster headache patients. There is still much to be learned about the brain and how it functions if the investigators are to understand the underlying causes of cluster headache. It is important to explore cutaneous allodynia in cluster headache as it may help guide physicians with the care of these individuals. Sixty patients will be screened for this study. Thomas Jefferson University is the only center enrolling patients in this research study.

The purpose of this study is to investigate the prevalence, characteristics and classification of headaches in epileptic patients.

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.

The purpose of this study was to investigate cultural adaptation, reliability and validity of the Turkish version of the Headache Impact Questionnaire (HIQ).

The coronavirus SARS-CoV-2 causing COVID-19 was pandemic since 2020. Vaccination is one of the most important measure to control the outbreak. The countries of the world started the vaccination since December, 2020. Taiwan started since March, 21st, 2021. Currently, Taiwanese people receive COVID-19 vaccination by either AZ or Moderna; Pfizer/BNT vaccine may import in the near future. The side effects post vaccination including injection site pain, fatigue, headache, myalgia, chills, arthralgia, fever, and so on. Incidence of side effects more frequent in young people than elders; more frequent in the first dose than second dose in AZ vaccine; more frequent in the second dose in Moderna or Pfizer/BNT vaccine. Taiwan V-watch is a system monitored by CDC for people proactive notification of side effects post COVID-19 vaccination. But it doesn't include the objective cardiovascular parameters, for example, heart rate, arrhythmia, blood pressure, central body temperature (ear temperature) and blood oxygen saturation level. This study aims to monitor the physiologic and psychologic effects, and side effects before and after COVID-19 vaccination in patients at high cardiovascular risk, including hypertension, hyperlipidemia, and type 2 diabetes, and arrhythmia or coronary artery disease. The investigators arrange two weeks of continuous home BP/HR monitoring (7 days pre- and post-vaccination) for evaluation of physiologic effects post vaccination. Due to fever noted in some people post-vaccination, the investigators also measure ear temperature, pulse oximetry, and environmental temperature and humidity, for the reference of BP monitoring. In conclusion, this study may provide important information of cardiovascular response and psychosocial effects after SARS-CoV-2 vaccination for proactive prevention of cardiovascular complications.

Migraine is prevalent in 10-12% of the population. It involves the development of a cranial perivascular neurogenic inflammation. Recent information suggests that migraine might be a risk factor to stroke. The possible mechanisms that might relate migraine and stroke are: 1. Migraineous infarction 2. A primary endothelial disorder. 3. Genetic relation 4. An ongoing inflammatory process. C reactive protein (CRP) is a sensitive marker for an inflammatory process.The data on the relation of migraine to inflammation is limited. The aim of the current study is to assess inflammatory factors as possible markers for migraine.

The occipital nerve stimulation (ONS) is used to treat patients with refractory primary chronic headache but its mechanism of action (MoA) remains unknown. Different hypothesis have been suggested in particular a specific action on cerebral generators involved in different types of primary headaches or a non specific action on pain modulatory network. The aim of this study, using the chronic cluster headache as a model, is to determine the changes in cerebral metabolism induced by ONS to precise its MoA in the treatment of primary chronic headache.

The aim is to establish how headache and migraine can affect muscle hardness and tenderness in migraine patients

Pulsed radiofrequency of the occipital nerves (greater and lesser) for primary headache management.

Study hypotheses: Children with headaches will show significantly higher sensory reactivity, higher anxiety level and lower quality of life that health controls. Among children with headaches, sensory reactivity will significantly correlate with higher anxiety level and lower quality of life. Among children with headaches quality of life will be predicted by sensory reactivity and anxiety level. Study significance: This is one of the first studies to explore the role of sensory reactivity and its relation to the psychological (anxiety) aspects among children and youth with headaches. Moreover, by using an elaborated point of view this study also measures the interaction between these factors and the child's quality of life. Referring to this interaction is critical for the intervention process in the meaning of: (a) helping determine whether pediatric headaches is best conceptualized as a CNS disorder, an emotional disorder, or some hybrid (b) increasing physicians' recognition of headaches pathogenesis and related outcomes, encouraging physicians to refer in the intake and intervention to both children and parents and when needed - to consider mental health services for child/parents. (c) to illuminate the physiological/psychological factors that have the most significant impact on QOL of children with headaches. Methods: Participants: The sample will include 60 children aged 8-18 years. The study group will include 30 children diagnosed with Primary headache - Migraine or TTH. They will be recruited from the pediatric neurological clinic in Bnai-Zion Health Center. The control group will include 30 children from the community with typical development and no history of chronic headaches or another chronic disease, no ADHD or learning disabilities, matched by age, gender and socio-economic status to the study group. Inclusion criteria for the study group: Children with Primary headaches diagnosed as Migraine or TTH between 8-18 years of age. Exclusion criteria for the sample group Evidence of an inflammatory, anatomic, metabolic, or neoplastic process that explains the subject's symptoms.
