Definition
Meaning and Definition
A medical condition where multiple scars form on the brain and spinal cord, interrupting nerve signals.
A chronic autoimmune neurological disease characterized by inflammation, demyelination (damage to the protective covering of nerve fibres), and the formation of sclerotic plaques in the central nervous system, leading to a wide range of potential physical, mental, and psychiatric symptoms.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning. 'Multiple sclerosis' (MS) is the overwhelmingly preferred term in both varieties. 'Disseminated sclerosis' is an archaic/technical synonym.
Connotations
In both varieties, 'disseminated sclerosis' sounds formal, dated, and highly clinical. It may be used in historical medical texts or for precise taxonomic distinction in specialist neurology.
Frequency
Extremely low frequency in general language. 'Multiple sclerosis' is at least 100 times more common in both UK and US corpora. 'Disseminated sclerosis' is essentially obsolete in everyday usage.

Usage
Meaning in Context
Business
Not used.
Academic
Used primarily in historical or highly specialised medical/neurological literature to refer specifically to the disseminated (widespread) plaque form of MS.
Everyday
Virtually never used; 'multiple sclerosis' is the universal term.
Technical
The term may appear in differential diagnoses, older medical records, or specific pathological descriptions to emphasise the scattered nature of the lesions.

Common Mistakes When Using “disseminated sclerosis”
- Mispronouncing 'sclerosis' with a hard 'c' (/sklerosis/). The 'sc' is /sk/.
- Confusing it with 'amyotrophic lateral sclerosis' (ALS), a completely different disease.
- Using it in general conversation where 'multiple sclerosis' is expected, causing confusion.
FAQ
Frequently Asked Questions
Yes, they are different names for the same neurological disease. 'Multiple sclerosis' (MS) is the modern and overwhelmingly preferred term.
A doctor today would be very unlikely to use it. It might appear in highly specific academic or historical discussions to refer to the classic 'disseminated in time and space' plaque distribution that defines MS.
It comes from Latin, meaning 'scattered' or 'spread widely'. It refers to the disease's characteristic of causing multiple, separate areas of scarring (sclerosis) in the brain and spinal cord.
No. Both contain '-sclerosis' (hardening), but they affect completely different systems. Arteriosclerosis is hardening of the arteries (blood vessels), while disseminated sclerosis/multiple sclerosis is a disease of the central nervous system.
A medical condition where multiple scars form on the brain and spinal cord, interrupting nerve signals.
Disseminated sclerosis is usually technical / medical in register.
Disseminated sclerosis: in British English it is pronounced /dɪˌsɛm.ɪ.neɪ.tɪd skləˈrəʊ.sɪs/, and in American English it is pronounced /dɪˈsem.ə.neɪ.t̬ɪd skləˈroʊ.sɪs/. Tap the audio buttons above to hear it.

Learning
Memory Aids
Mnemonic
Think of seeds being DISSEMINATED (scattered) across a field, and SCLEROSIS as hard patches. The disease scatters hard patches of scar tissue in the nervous system.
Conceptual Metaphor
DISEASE IS AN INVADER (that disseminates/scatters through the nervous system); NERVES ARE WIRES (that become hardened/sclerotic and lose their insulation).
