disseminated multiple sclerosis
Noun: A chronic, progressive neurological disorder characterized by the widespread loss of the myelin sheath—the protective covering—around nerve fibers in the central nervous system (brain and spinal cord). This damage disrupts the normal transmission of nerve signals.
Disseminated multiple sclerosis is the formal medical term for the most common form of multiple sclerosis (MS). It describes the condition where lesions (areas of demyelination) are "disseminated" or scattered in multiple locations within the central nervous system and occur at multiple times. * The diagnosis of disseminated multiple sclerosis was confirmed by MRI scans showing lesions in both the brain and spinal cord. * Research into disseminated multiple sclerosis focuses on understanding what triggers the immune system to attack the myelin sheath.
- The term is often used in historical or very specific clinical contexts. In modern clinical practice, this condition is more commonly referred to simply as multiple sclerosis (MS) or more specifically as relapsing-remitting MS (RRMS) during its most common initial phase.
- Multiple sclerosis (MS): The general, more commonly used term for the disease.
- Relapsing-remitting multiple sclerosis (RRMS): The most common disease course, characterized by clearly defined attacks of new or increasing symptoms (relapses) followed by periods of partial or complete recovery (remissions).
- Demyelinating disease: A broader category of disorders that involve damage to the myelin sheath, of which MS is one type.
- Multiple sclerosis (MS)
- Disseminated sclerosis (an older, synonymous term)
- To be diagnosed with MS: The standard phrasing for receiving a formal identification of the condition.
- She was diagnosed with multiple sclerosis last year.
- MS flare-up / relapse / exacerbation: Terms used to describe a period where new symptoms appear or existing symptoms worsen.
- He is managing an MS flare-up with corticosteroid treatment.
