How does mental retardation affect the child?
Mental retardation affects a child’s development in many respects:
• physical functions, for example the child’s ability to walk and using his hands;
• self-care, for example the ability to feed, bathe and use the toilet independently;
• communication with others by talking and understanding what is being said;
• social functioning, such as playing with other children;
• mental illness ;
• physical disabilities and diseases (the more severe the mental retardation, the greater will be the chance of physical health problems such as seizures and physical disabilities);
• family problems caused by guilt, unhappiness and anger about the child’s mental retardation.
