Multiple sclerosis diagnosis can only be made when there is proof of lesions disseminated in time and in space. Therefore, when damage in the CNS is big enough to be seen. It would be desirable to make it faster. The ideal diagnosis schema would be able to determine for any given subject, if he will develop MS, at any point in his life, and when.
MRI findings that are consistent with multiple sclerosis have been observed in healthy people who underwent MRI scanning, and 50% go on to develop symptomatic MS, sometimes with a primary progressive course. [2] [3] This condition was first characterized in 2009. [4]
Abundant extracellular myelin in the meninges of patients with multiple sclerosis has been found [118] Brain tissues with MRI-hidden problems are usually named Normal Appearing. Exploring the normal-appearing corpus callosum has been found a possible primary hypoperfusion, [119] according with other findings in this same direction.
Dawson's Fingers appearing on an MRI scan. Multiple sclerosis and other demyelinating diseases of the central nervous system (CNS) produce lesions (demyelinated areas in the CNS) and glial scars or scleroses. They present different shapes and histological findings according to the underlying condition that produces them.
Multiple sclerosis (MS) is an autoimmune disease resulting in damage to the insulating covers of nerve cells in the brain and spinal cord. [3] As a demyelinating disease, MS disrupts the nervous system's ability to transmit signals, resulting in a range of signs and symptoms, including physical, mental, and sometimes psychiatric problems.
The McDonald criteria maintained a scheme for diagnosing MS based solely on clinical grounds but also proposed for the first time that when clinical evidence is lacking, magnetic resonance imaging (MRI) findings can serve as surrogates for dissemination in space (DIS) and/or time (DIT) to diagnose MS. [5] The criteria try to prove the existence ...
Main symptoms of multiple sclerosis Symptoms and findings in multiple sclerosis. Multiple sclerosis can cause a variety of symptoms varying significantly in severity and progression among individuals: changes in sensation (hypoesthesia), muscle weakness, abnormal muscle spasms, or difficulty moving; difficulties with coordination and balance; problems in speech or swallowing (), visual ...
Currently the best predictor for clinical multiple sclerosis is the number of T2 lesions visualized by MRI during the CIS, but it has been proposed to complement it with MRI measures of BBB permeability [97] It is normal to evaluate diagnostic criteria against the "time to conversion to definite".
