Definition
  1. Noun:
    • A rare, fatal, hereditary disorder of lipid metabolism: "Infantile amaurotic idiocy" is a medical term for a severe genetic disease. It is characterized by the abnormal accumulation of lipids (fats) in the cells of the nervous system, particularly the brain. This accumulation leads to progressive neurological damage.
Usage
  • Noun:
    • This term is used specifically in medical and historical contexts to describe this condition.
    • The diagnosis was infantile amaurotic idiocy, a devastating prognosis for the family.
    • Research into infantile amaurotic idiocy has helped advance our understanding of lysosomal storage diseases.
Advanced Usage
  • The term "infantile amaurotic idiocy" is an older, now largely outdated and pejorative name. In modern medical terminology, this condition is more precisely and respectfully referred to as Tay-Sachs disease.
    • The genetic screening program aims to identify carriers of the mutation that causes what was historically called infantile amaurotic idiocy.
Variants and Related Words
  • Tay-Sachs disease (n): The modern, standard term for this condition.
  • GM2 gangliosidosis, Type I (n): The biochemical classification of the disease.
  • Amaurotic (adj): Relating to or characterized by amaurosis (loss of vision without apparent lesion of the eye).
    • The amaurotic symptoms were an early sign of the disorder.
Synonyms
  • Tay-Sachs disease: The primary synonym in contemporary use.
  • B variant GM2 gangliosidosis: A technical synonym.
Notes on Meaning
  • The term historically combined descriptive features of the disease: "infantile" (onset in infancy), "amaurotic" (referring to the blindness that occurs), and "idiocy" (an outdated and offensive term for severe intellectual disability). Its use today is primarily historical or within specific scholarly contexts discussing the evolution of medical nomenclature. Modern usage strongly favors "Tay-Sachs disease."
Noun
  1. a hereditary disorder of lipid metabolism occurring most frequently in individuals of Jewish descent in eastern Europe; accumulation of lipids in nervous tissue results in death in early childhood
