Magnetic Resonance Imaging to Detect Brain Damage in Patients With Multiple Sclerosis

Completed

Conditions studied: Multiple Sclerosis

In brief

This study will test the ability of magnetic resonance imaging (MRI) to detect damage in different parts of the brain in patients with multiple sclerosis and to see if cognitive problems in patients can be correlated with the presence of lesions or reduction in the size of certain part of the brain. Healthy subjects will also be studied to compare findings in patients with those of normal volunteers. Healthy subjects and patients with multiple sclerosis who are between 18 and 60 years of age may be eligible for this study. Patients must not have severe clinical disability and must have been receiving and responding to Interferon beta for at least 6 months prior to enrollment. Candidates are screened with a medical history, physical examination, MRI and possibly evoked potential testing, which measures the nervous system response to visual, auditory and somatosensory stimulation. Participants have two MRI scans within 1 week (inclusive of the one performed for screening). MRI uses a magnetic field and radio waves to obtain images of body tissues and organs. The scanner is a metal cylinder surrounded by a strong magnetic field. During the MRI, the subject lies on a table that can slide in and out of the cylinder. Participants will be tested with magnet strengths of 1.5 and 3 Tesla; the higher the Tesla, the greater the ability to see brain changes. Each scan may last up to 90 minutes. In addition to the MRI scans, participants undergo cognitive testing that measures memory and thought processes and complete forms that test and quantify fatigue level, stress, anxiety and depression
