It is characterized by both focal and diffuse damage. Physiopathologically, MS is due to circulating autoaggressive lymphocytes that penetrate the blood-brain barrier and attack the myelin layer of axons. This provokes demyelination and axonal damage, demonstrated Prof. Christina Granziera, MD, Basel. Traditionally, three manifestations of relapsing-remitting (RRMS), secondary progressive (SPMS) and primary progressive (PPMS) MS are distinguished ( <span style=\"font-family:franklin gothic demi\">Fig.&nbsp;1)<\/span>. All are associated with different levels of inflammatory activity and clinical progression.<\/p>\n<p>&nbsp;<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\" size-full wp-image-16039\" alt=\"\" src=\"https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/09\/abb1_np2_s24.png\" style=\"height:272px; width:600px\" width=\"1100\" height=\"499\"><\/p>\n<p>&nbsp;<\/p>\n<p>The diagnosis of relapsing-remitting MS is made on the basis of at least two clinically demonstrated relapses and at least two lesions. Lesions must be objectively demonstrated clinically. If only one relapse or lesion can be detected, additional requirements must be met with spatial and\/or temporal dissemination<span style=\"font-family:franklin gothic demi\"> (Tab.&nbsp;1)<\/span>. PPMS is diagnosed when the patient has been in clinical disability progression without relapses for at least one year and at least two of the following factors are met:<\/p>\n<ul>\n<li>A T2 lesion on MRI and at least one periventricular, cortical\/juxtacortical, or infratentorial lesion.<\/li>\n<li>at least two T2 lesions on spinal MRI<\/li>\n<li>intrathecal immunoglobulin synthesis<\/li>\n<\/ul>\n<p>To date, there is no consensus for the diagnosis of SPMS. Different definitional options have been proposed. For example, the presence of continuous deterioration for at least one year, two consecutive sustained disabling events (independent of relapses), or steadily increasing neurologic dysfunction without clear improvement. According to the population-based MS-Base study, a clinical diagnosis of SPMS exists when at least three months of EDSS progression can be demonstrated in the absence of a relapse. In addition, the deterioration must amount to at least one EDSS level if the EDSS was below six before progression and 0.5 EDSS level if it was above six. Also, the EDSS after progression must be at least four with a pyramidal FS score greater than two.<\/p>\n<h2 id=\"\">&nbsp;<\/h2>\n<h2 id=\"-2\"><img decoding=\"async\" class=\"size-full wp-image-16040 lazyload\" alt=\"\" data-src=\"https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/09\/tab1_np2_s26.png\" style=\"--smush-placeholder-width: 1100px; --smush-placeholder-aspect-ratio: 1100\/589;height:321px; width:600px\" width=\"1100\" height=\"589\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\"><\/h2>\n<h2 id=\"-3\">&nbsp;<\/h2>\n<h2 id=\"focus-on-differential-diagnoses\">Focus on differential diagnoses<\/h2>\n<p>When a patient presents with clinical deficits consistent with an MS relapse and the MRI scan demonstrates spatial dissemination, the following differential diagnoses should be considered:<\/p>\n<ul>\n<li>Infections\/inflammations<\/li>\n<li>Neoplasia, NMOSD\/MOGAD<\/li>\n<li>Cerebrovascular diseases<\/li>\n<li>Migraine<\/li>\n<li>Leukodystrophies, mitochondrial diseases<\/li>\n<\/ul>\n<p>However, not only the characteristics of the lesions, but also their localizations can provide clues to possible other diseases. In recent years, several important radiological biomarkers have been developed to aid MS diagnosis. This includes, for example, the central vein. If at least 35% of CV lesions and two CVS lesions have a central vein, the presence of MS can be assumed with high specificity and sensitivity. Another biomarker are so-called paramagnetic rim lesions (PRL). It identifies activated, iron-containing cells and usually indicates chronic inflammatory lesions, the expert said. The differential diagnosis of other inflammatory demyelinating diseases of the CNS is particularly challenging. These include NMOSD, ADEM, MOG, or Bal\u00f3 disease, among others. In addition to clinical features, radiological and fluid biomarkers can also help distinguish MS from other diseases.<\/p>\n<h2 id=\"-4\">&nbsp;<\/h2>\n<h2 id=\"-5\"><img decoding=\"async\" class=\"size-full wp-image-16041 lazyload\" alt=\"\" data-src=\"https:\/\/medizinonline.com\/wp-content\/uploads\/2021\/09\/tab2_np2_s26.png\" style=\"--smush-placeholder-width: 717px; --smush-placeholder-aspect-ratio: 717\/1312;height:732px; width:400px\" width=\"717\" height=\"1312\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\"><\/h2>\n<h2 id=\"-6\">&nbsp;<\/h2>\n<h2 id=\"effective-therapy-management\">Effective therapy management<\/h2>\n<p>Most of the available MS therapies target B and T cells outside the CNS, but other options also act directly in the CNS <span style=\"font-family:franklin gothic demi\">(Table&nbsp;2) <\/span>.
