Patient's question:
Half-open mouth, round and flat face, small eyes, low nose bridge, tongue often sticking out, short feet - does this definitely mean congenital hypotonia?Doctor's answer:
Down syndrome, also known as congenital idiocy, is the most common birth defect caused by chromosomal abnormalities in children. As the name suggests, this condition is an intellectual disability with a specific phenotype caused by congenital factors. Infants with this condition already have a distinct facial appearance at birth and often exhibit lethargy and feeding difficulties. As they grow older, their intellectual disability becomes more apparent, with delayed motor and sexual development.Their distinctive facial features include: a small, round head; wide-set eyes; small palpebral fissures; upward slanting outer corners of the eyes; epicanthal folds; a flat nasal bridge; small ears; a narrow hard palate; and a tongue that often protrudes from the mouth, with excessive drooling.
Intellectual disability: This is the most prominent and severe symptom, with an IQ typically ranging from 25 to 50, and abstract thinking abilities being most severely affected.
Therefore, the situation you described has a high possibility of being congenital idiocy, but it cannot be diagnosed solely based on symptoms, so a definitive diagnosis cannot be made. The only definitive method for confirmation is peripheral blood cell chromosome analysis.
