What comes to your mind when you hear the word mental retardation? Many times we said this word without knowing what really is. Mental retardation is a condition, not a disease, also termed as "intellectual disability". People with this condition have an IQ below 70 approximately, have difficulties with dressing, feeding oneself, communicating and other daily life skills. Because mental retardation is a condition and not a disease, there is no cure.
There are about 200 different causes of mental retardation, but one of the most common condition is Down syndrome. This condition is also called Trisomy 21 because is a chromosomal condition caused because of the presence of an extra 21st chromosome. People with Down syndrome are considered to have moderate retardation. The IQ of moderate retardation is from 35 to 29. Some physical characteristics of this condition are flat nose, upwardly slanted eyes, short neck and protruding tongue.
Below is a video that talks about mental retardation, but what I wanted to point is the last part in which says that we need to remember when we say to someone the word retarded because it hurts. These people can have mental retardation, but are as human like us with feelings. We need to be aware to be nice and treat them normal without any kind of fear. I consider them as special humans. What you think about that?
