Down Syndrome: An Intellectual and Developmental Disability

Down Syndrome: Intelligence and Developmental Disorders When studying the specialty of children's textbooks for special education, I chose to study further Down Syndrome. This is one of the most common and easily identifiable abnormalities, based on the prevalence of Down's syndrome, this is an exception Down's syndrome is a genetic disease that may lead to intelligence and development is. People with Obstacle Down Syndrome have a common intention with extra chromosomes; instead of 46, they have 47 chromosomes.

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

The severity of Down's syndrome varies from person to person, leading to lifelong mental retardation and stunning. It is the most common cause of childhood genetic chromosomal abnormalities and learning disorders. It often also causes other medical abnormalities including heart and gastrointestinal diseases. When abnormal cell division involving chromosome 21 occurs, these cell division abnormalities in Down's syndrome result in additional partial or complete chromosomes 21 This additional genetic material leads to Down Syndrome characteristics and developmental problems . Any of the three genetic variants can cause Down's syndrome.
