Patient's question:
My brother's daughter is mentally disabled. Every time she sees me, she comes over and tries to strangle me fiercely. The places she squeezes turn black. I don't understand what will happen to such a child. I also don't understand why there are mentally disabled children?Doctor's answer:
Children with intellectual disabilities are caused by many factors, such as intergenerational inheritance, low intelligence of parents, and consanguineous marriage or parents with chromosomal abnormalities. Parents suffering from certain metabolic diseases, such as phenylketonuria, can pass congenital intellectual defects to their offspring, leading to intellectual disabilities in children. If one parent has low intelligence or both parents have low intelligence, the incidence of intellectual disability in their children can be as high as 77-96%. Wishing the patient a speedy recovery and good health!
