Definition
  1. Adjective:
    • Characterized by the partial or total absence of a brain: This is a medical term describing a severe congenital condition where a fetus or infant is born without major portions of the brain, skull, and scalp.
Usage
  • The word "anencephalous" is a highly specialized medical adjective. It is used almost exclusively in clinical, pathological, or scientific contexts to describe a specific and severe birth defect. It is not used in everyday conversation.
Examples
  • Adjective:
    • The ultrasound revealed an anencephalous fetus.
    • Anencephalous infants rarely survive for long after birth.
    • The study focused on the causes of anencephalous development.
Advanced Usage
  • The term is typically used attributively (before a noun) as in "anencephalous infant" rather than predicatively. Its use is strictly descriptive within a medical framework.
Variants and Related Words
  • Anencephaly (n): The name of the condition or disorder itself.
    • Anencephaly is a fatal neural tube defect.
  • Anencephalic (adj): A more common variant adjective with identical meaning.
    • The report described the specimen as anencephalic.
Synonyms
  • Medical Synonym: Anencephalic (adj). There are no true common-language synonyms for this precise medical term. Descriptive phrases like "lacking a brain" or "born without a brain" convey the general idea but lack clinical specificity.
Antonyms
  • There is no direct single-word antonym. The opposite condition would be described as "neurologically normal" or "with a fully developed brain."
Notes
  • "Anencephalous" is derived from Greek roots: (without) + (brain). It is a formal, technical term.
