Patient's question:
Male, 28 years old, mental state not very good recently, don't know what's going on. Please ask: What are the symptoms of Down syndrome?Doctor's answer:
Children with Down syndrome typically exhibit distinctive facial features, such as wide-set eyes, a protruding tongue that often sticks out of the mouth, a smaller head circumference than normal, short stature, and overly bent joints. Male children will remain infertile during puberty, while female children will have menstruation and may be able to conceive. Their immune systems are weakened, and the risk of leukemia is 10-30 times higher than in others. If they live to adulthood, they may experience symptoms of Alzheimer's disease after the age of 30.
