Down Syndrome: An Intellectual and Developmental Disability

When completing the special child course, I used the "educational special child" textbook. This textbook covers a variety of special situations, but I chose to study further down syndrome. It is one of the most common and easily identifiable abnormalities, based on the high prevalence of Down's syndrome, about 733 births ("Down syndrome"), although this may be an exception, I will encounter more. My educational history is more.

It is important to remember that people with Down's syndrome and other intellectual and developmental disorders are important targets for the American eugenics movement - this is important for Hitler's under the Aktion-T 4 program in 1939 It affected the first mass murder. Through this program, Hitler killed an estimated 200,000 people with mental retardation and developmental disability. Many of them are Down Syndrome. It is important to remember that until 1984, American physicians refused to provide life support for people with Down Syndrome like cardiac related surgery. Even today, some people with Down syndrome die from 30 years old or 40 years old because doctors refused to undergo cardiac surgery during infancy.

There are various kinds of developmental disorders. Among many developmental disorders are mental retardation, Down's syndrome, cerebral palsy, autism spectrum disorder, ADHD, hearing and vision disorders, and learning disabilities. We explore many kinds of developmental disorders. Mental retardation is often referred to as mental retardation, but this term is no longer used because it is aggressive (Leahy, Fuzy & Grafe, 2013). To be mentally retarded means that the person's cognitive ability is lower than the average person's age. Mentally handicapped persons may range from mild to severe mental retardation (CDC, 2015 d).

Mental retardation is further subdivided into intellectual disorders of the syndrome where mental deficits associated with other medical and behavioral signs and symptoms as well as nonsyndromic mental retardation in which mental retardation occurs without other abnormalities There is. Down syndrome and fragile X syndrome are examples of symptomatic mental retardation. Mental retardation affects approximately 2 to 3% of the general population. 75% to 90% of the affected population suffers from mild intellectual disability. Nonsyndromic or idiopathic cases account for 30 to 50% of cases. Approximately one quarter of cases are caused by hereditary diseases, and about 5% of cases are inherited from one parent. As of 2013, cases of unknown cause affected about 95 million people
