Background and Purpose—We explored the association between transcranial Doppler hemodynamic parameters and the risk of stroke in the general population. Methods—At baseline, we assessed mean flow velocity, peak systolic flow velocity, end diastolic flow velocity, and vasomotor reactivity with transcranial Doppler in 2022 Rotterdam Study participants aged 61 years and over in both middle cerebra...

background: an imbalance of the cerebrovascular response during functional activation of the brain has been postulated as a factor in the pathophysiology of migraine. the purpose of this study was to determine the transcranial doppler sonography (tds) diagnostic value for the cerebral flow velocity changes in the interictal phase of classic migraine. methods: this study was carried out on 46 pa...

BACKGROUND The purpose of this study was to identify determinants of coronary artery reactivity among premenopausal female monkeys. Estrogen replacement therapy in postmenopausal females modulates reactivity of atherosclerotic coronary arteries. However, no studies have evaluated the factors that modulate coronary artery reactivity among premenopausal females. METHODS AND RESULTS Twenty-five ...

Abstract Background Multiple sclerosis (MS) is the most common demyelinating disease of central nervous system. Autonomic dysfunction present in a wide range patients (15–80%) that might with abnormalities regulation cardiovascular system, sleep disturbance, urinary symptoms, sexual problems, and temperature problem. Although predominant view an autoimmune inflammatory condition, changes brain ...

Vasomotor rhinitis is the most common form of nonallergic rhinitis, comprising approximately 71% of all nonallergic rhinitis conditions. Although the epidemiology of this subtype of nonallergic rhinitis has not been definitively studied, it is estimated that 14 million Americans suffer from vasomotor rhinitis, with a worldwide prevalence approaching 320 million.
