After continuous verification and research by previous scientists, unremitting efforts have finally confirmed that Down syndrome is caused by chromosomal abnormalities in the body. And modern medicine has confirmed that the incidence of this disease is related to the age of the mother during pregnancy. So what are the symptoms of Down syndrome patients?
Firstly, the most obvious symptom of patients with Down syndrome is the difference in appearance, where they have a distinct special face. It is generally manifested as a wider distance between the eyes than the average person, a lower and flatter nasal root, and an upward sloping appearance outside the eyes. The tongue tends to be chubby and often extends out of the mouth, causing excessive drooling.
In addition, their figures are generally short and their head circumference is smaller than that of normal people. In addition to appearing different from ordinary people, they often experience symptoms of drowsiness and feeding difficulties. Their intelligence is relatively low, and this abnormal condition may not be very obvious at birth, but it will become more and more obvious with age.
In addition to the delayed development of daily behaviors and movements, there is also a delay in sexual development. Regarding sexual development, patients with Down syndrome may exhibit different symptoms depending on their gender. If it's a boy, even if they reach puberty, they won't have the ability to have children. But if a girl suffers from Down syndrome, she will have menstruation and be able to conceive after entering puberty.
