Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This a retrospective, blinded trial in which collaborators in Italy will review the doppler findings from the Combined Transcranial and Extracranial Venous Doppler (CTEVD) trial in an attempt to measure reproducibility.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will retrospectively investigate doppler images from the second phase of the CTEVD trial.

1. To determine the prevalence of CCSVI in patients with MS, compared with the prevalence observed in a control population consisting of Other Neurological Diseases (OND) patients and Healthy Controls (HC) by using blinded, controlled centralized ultrasound reading assessment of 5 Venous Haemodynamic (VH) CCSVI CCSVI Doppler UltraSound (CDUS) criteria.
2. To investigate whether prevalence of CCSVI is different between centralized and local CDUS reading of 5 VH CCSVI CDUS criteria.
3. To investigate the prevalence of CCSVI in patients with MS, compared with the prevalence observed in a control population consisting of OND patients and HC, when bidirectional flow in the intracranial veins and sinuses CDUS criterion is not considered as part of VH CCSVI CDUS criteria.
4. To determine whether prevalence of CCSVI in patients with MS, compared with the prevalence observed in a control population consisting of OND patients and HC differs when using CDUS velocity and flow parameters in the Internal Jugular Veins (IJVs) and Vertebral Veins (VVs).
5. To determine the reproducibility of VH criteria by using of centralized and local blinded, controlled CDUS reading assessment.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Multiple Sclerosis

Patients diagnosed with Multiple Sclerosis (MS), identified in the CTEVD trial

No interventions assigned to this group

Clinically Isolated Syndrome

Patients diagnosed with Clinically Isolated Syndrome (CIS), identified in the CTEVD trial.

No interventions assigned to this group

Other Neurological Disorders

ONDs fall into one of four categories: Neurodegenerative, Vascular, Autoimmune, and Neuromuscular; and the following disorders: Acute Disseminated Encephalomyelitis (ADEM); Antiphospholipid Antibody (syndrome; APLA); Atypical, short-lasting neurodegenerative disease; Autoimmune disease not otherwise specified (NOS); Cerebellum Syndrome; Charcot-Marie Tooth Disease; Chiari Malformation; Chronic Fatigue Syndrome; Central Nervous System Vasculitis; Demyelinating Disease; Epilepsy; Headaches; Idiopathic Chronic Neuropathy; Migraines; Mitochondrial Disease; Myelopathy; Neurofibromatosis; Neuropathy; Optic Neuritis; Parasthesia related to Transient Ischemic Attacks (TIA); Parkinson's Disease; Restless legs syndrome; Seizures; Spinal Cerebellum Disease; Spinal Disc Degeneration; Syringomyelia; and Vertigo

No interventions assigned to this group

Healthy Controls
