Children suffering from mental retardation are slow in everything as compared to other healthy children of the same age. They learn even the simpler things more gradually as sitting, standing, talking, crawling etc. The prime target of this order is as mentioned, children before they reach the age of 18. The symptoms of this disorder that are detrimental in effective diagnosis of the disorder involve: slow oral language growth, falling short of memorizing easily, difficulties in socialization, hindrances in troubleshooting, slow growth of learning different skills from the environment and implementing those skills themselves, and lacking in social substances (Baker & Ainsworth, 2004).
The constraints of learning development makes a child suffer mental retardation, making him grow just two slowly as compared to other children of the same age. Not only children suffering from mental retardation take longer periods to learn but they would also require repetitive learning in order to memorize what they have learnt in that long period. However, children so grow and develop even with this disorder and become potent contributors of the society, it is just the matter of time.
The diagnosis of this disorder is a bit complex as many of the other metal and psychological disorders. Researchers (Zigler & Balla, 1983) have recommended that in order to successfully diagnose any patient with mental retardation, it is necessary to check three different criteria. First criteria or condition is the fact that the child should have an IQ level under 70. The other significant point is the fact that children under diagnosis of mental retardation should lack in at least two sectors of adaptive conducts. This is measurable by an adaptive conduct rating scale, this scale shows efficiency of a child in different areas such as communication,
