Extremely Rare / ObsoleteTechnical / Medical / Archaic
Definition
Meaning
A pathological term for a softening or degenerative change in brain tissue.
Specifically refers to a morbid softening or disintegration of brain substance, often due to disease processes like ischemia, infection, or trauma. It is not a common medical diagnosis but a descriptive pathological finding.
Linguistics
Semantic Notes
This term is primarily encountered in older medical literature (19th to early 20th century) and is now largely superseded by more precise diagnostic terms like encephalomalacia, ischemic necrosis, or liquefactive necrosis of the brain. It is not used in contemporary clinical practice or neurology.
Dialectal Variation
British vs American Usage
Differences

Connotations
Archaic, technical, and descriptive of a pathological state. It carries no modern clinical connotation.
Frequency
Effectively zero frequency in modern usage in both dialects. Likely unknown even to most general medical practitioners.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'энцефалоз' – a non-standard pseudo-translation. The established Russian medical term for this concept is 'энцефаломаляция' (encephalomalacia). 'Энцефалоз' may lead to misunderstandings or be perceived as a neologism.
Common Mistakes
- Using it as a modern diagnosis. Confusing it with encephalitis (inflammation) or encephalopathy (general brain dysfunction). Attempting to use it in contemporary writing.

It is not recommended. You should use contemporary, precise terms like 'encephalomalacia', 'ischemic necrosis', or 'liquefactive necrosis' depending on the specific context.
Encephalitis refers to inflammation of the brain (usually due to infection or autoimmunity). Encephalosis (obsolete) refers to a softening or degenerative change in brain tissue, which could be a result of inflammation, among other causes.
Historical and comprehensive dictionaries document the full history of a language, including words that have fallen out of active use. This aids scholars in reading older texts and understanding the evolution of terminology.
