I filled out the volunteer questionnaire for the Combined Transcranial and Extracranial Venous Doppler (CTEVD) Evaluation in MS and related Diseases study in Buffalo, NY.
The main goal of the CTEVD study is to investigate the prevalence (frequency) of CCSVI in patients with multiple sclerosis (MS) when compared to healthy controls (HC) and controls with other neurological disorders (OND). Another important aim of the CTEVD study is to investigate the relationship between CCSVI and clinical, magnetic resonance imaging (MRI) and environmental-genetic outcomes in MS patients, HC, and controls with OND.
There are no treatment interventions planned in this study. The study procedures include doppler/ultrasound testing, blood collection, a clinical examination and completion of an Environmental Questionnaire. Interested participants can also have an MRI performed. A subset of these individuals with also have an MRI of the neck veins.
