Most of mild mental retardation from minority groups and social backgrounds and expertise
Down to the general population. Many more remain behind in the minority groups indicate
Significant effects on the environment - cultural and genetic.

Moderate retardation: a retarded one tenth largest group of

Most of that intelligence and social adjustment problems. Mentally retarded children
Often during preschool ages of 2-3 years appears.

Many people with this kind of lag one or multiple organ failure
Are identified., For example, the number of people with the syndrome and the syndrome
Fragile X mental retardation are at an intermediate level. They are about six years

Stressful conditions are required supervision and guidance of 0.1

Severe retardation: a retarded group of around four percent

Profound mental retardation: Mental retardation is less than the number of
Percent of them are backward and their IQ is lower than the 25-30, at least
The ability of sensory functions - to move 0.1 and nursing needs constant support. Few of them somewhat self-care ability and speech, and learn simple social behavior, but the
However, they require constant nursing care.

Local retardation: Floor
Unknown persons suspected to cause retardation of mental retardation
Measurement is different, is considered. These sub-categories if the imagination
A person's IQ is higher than 70 is not used.

Epidemiology
The incidence of retardation
Mind on Statistics vary. Looks digits 1 to 3 percent figure
Be more acceptable. Statistics show that boys lagged about 1/5 for girls back
Are needed.

In the very back
May be retained for a long time before it is known which individual constraints. Lies
Or remain in a certain stage of life due to good adaptation, not an official diagnosis
Did. Highest incidence in school children aged between 10 and 14 is the maximum.
With increasing age, the prevalence of severe or profound mental retardation due to mortality rates, years of Gee
The resulting blend is associated with physical abnormalities is less.

Etiology

A large group of mentally retarded from the start of the union of sperm and ovule are unknown, namely, interruption or disruption of a tug kill himself. Defect in a single gene or a gene pair, the
Loss, or loss of a chromosome was more important factors in severe retardation
Or are deep, though it rarely happens, but if it happens, the effects
Sharp leaves. Effects of another gene in mental retardation, poor performance, or
The lack of enzyme systems and chemical functions of the enzyme., In such a situation the body's inability
The production of the enzymes which metabolize fat, sugar and protein
Is the accumulation of excessive natural metabolic and intellectual development of children

The most obvious effect is manifested in the verbal process. This is considered
The high correlation between early verbal stimulation and intelligence, the intelligence development process, key
Plays. The quality stimulate children and how parents interact with the children's role in
