| − | The term mental retardation describes a certain range of scores on an IQ (intelligence quotient) test.The degree of impairment from mental retardation varies widely, from profoundly impaired to mild or borderline retardation Mental retardation can result from a number of different conditions genetic,environmental,infections present during birth,chromosomal abnormalities etc.[[File:mr.jpg|right]]

| + | [[Fragile X syndrome]] |
| − | The primary goal of treatment is to develop the person's potential to the fullest. Special education and training may begin as early as infancy. This includes social skills to help the person function as normally as possible.
| |
| − | It is important for a specialist to evaluate the person for other affective disorders and treat those disorders. Behavioral approaches are important for people with mental retardation.

| − | ==='''Down syndrome'''===
| |
| − | It is a set of mental and physical characteristics related to having an extra copy of Chromosome 21.There is extra genetic material causes delays in the way a child develops, both mentally and physically.It affects about 1 in every 800 babies.Women age 35 and older have a significantly higher risk of having a child with the condition. At age 30, for example, a woman has about a 1 in 900 chance of conceiving a child with DS. Those odds increase to about 1 in 350 by age 35. By 40 the risk rises to about 1 in 100.[[File:ds.jpg|right]]

| − | '''Conditions Associated:'''
| |
| − | | |
| − | The kids with this disorder tend to grow at a slower rate and remain smaller than their peers. Low muscle tone may contribute to sucking and feeding problems, as well as constipation and other digestive issues. They may have delays in speech and self-care skills like feeding, dressing, and toilet teaching.
| |
| − | Down syndrome affects kids' ability to learn in different ways, but most have mild to moderate intellectual impairment. They sometimes face host of medical issues that require extra care. For example, almost half of all children born with DS will have a congenital heart defect. Some have problems with hearing and vision.Other medical complications can be thyroid problems, intestinal abnormalities, seizure disorders, respiratory problems, obesity, an increased susceptibility to infection, and a higher risk of childhood leukemia.
| |
| − | | |
| − | '''Management:'''
| |
| − | | |
| − | It is very important to stimulate, encourage, and educate children with Down syndrome from infancy. Programs for young children with special needs are offered in many communities. Early intervention programs, including physical therapy, occupational therapy, and speech therapy can be very helpful.Behavioral training can help people with Down syndrome and their families deal with the frustration, anger, and compulsive behavior that often occur. Parents and caregivers should learn to help a person with Down syndrome deal with frustration. At the same time, it is important to encourage independence.Physical therapy may teach movement skills.

| |
| − | | |
| − | The most common inherited form of mental retardation caused by a defect in a specific part of the Fragile X Mental Retardation -1 gene that causes the body to produce low amounts or none of a certain protein. Without the protein, the brain doesn’t develop normally.
| |
| − | | |
| − | '''Symptoms:'''
| |
| − | | |
| − | Intelligence problems, ranging from learning disabilities to severe mental retardation
| |
| − | | |
| − | Social and emotional problems, such as aggression in boys or shyness in girls
| |
| − | | |
| − | Speech and language problems, especially in boys
| |
| − | | |
| − | '''Treatment:'''
| |
| − | Because a young child's brain is still forming, early intervention gives children the best start possible and the best chance of developing their full potential. Speech and language, behavior, cognitive development, sensory integration, gross motor development, and daily living are areas that often need to be addressed for someone with fragile X syndrome. While many of these areas require physical and behavioral intervention, medication is often an important component of the treatment.

| − | ===Autism Spectrum Disorders===
| |
| − | | |
| − | [[File:Autism.jpg|left]]It is a range of problems that can affect a person's communication skills, social skills, and intelligence. The degree of autism varies from mild to severe.Severely afflicted patients can have a profound intellectual disability. Autism Spectrum Disorders (ASD) can cause severe and pervasive impairment in thinking, feeling, language, and the ability to relate to others. These disorders are usually first diagnosed in early childhood and range from a severe form, called autistic disorder to a much milder form, Asperger syndrome. They also include two rare disorders, Rett syndrome and childhood disintegrative disorder.The cause of autism is unknown.
| |
| − | | |
| − | '''Symptoms:'''
| |
| − | All children with ASD demonstrate deficits in 1) social interaction, 2) verbal and nonverbal communication, and 3) repetitive behaviors or interests.They will often have unusual responses to sensory experiences, such as certain sounds or the way objects look.[[File:Autism1.jpg|right]]

| − | '''Treatment''':
| |
| − | | |
| − | While there is no established cure for autism, there are many treatments. Some help manage symptoms, other teach social and behavioral skills, and still others are intended to cure autism altogether.Persons with autism seem to have a higher mortality rate at younger ages due to seizures or infection.
| |
| − | #They need an educational program that is suitable to a student's developmental level of performance.
| |
| − | #Individuals with autism need to be taught how to communicate and interact with others.
| |
| − | #As individuals with autism also seem to be vulnerable to emotional struggles like anxiety, depression and attention problems, the involvement of mental health professionals should be taken.
| |
| − | #Psychotherapeutic approaches that have been found to help improve functioning in some persons with autism include comprehensive behavioral therapy to address problematic behaviors.
| |
| − | #Social skills training and support help people with autism to interact with others.
| |
| − | #Cognitive behavioral treatment too helps in some cases.
| |
| − | #Some medications have been found to help address some symptoms that may present in autism.

Developmental Disability
Nervous system disabilities
These are birth defects that affect the functioning of the brain, spinal cord, and nervous system, which can impact intelligence and learning. These conditions can also cause problems such as behavioral disorders, speech or language difficulties, convulsions, and movement disorders. Some of the common nervous system disabilities include:
Mental Retardation
Down syndrome
Autism Spectrum Disorders
Fragile X syndrome
Sensory-related disabilities
Sensory-related problems are often a key part of complex birth defect patterns. For instance:
Children with congenital rubella are likely to be deaf, and to develop cataracts of the eyes.
Children with Williams syndrome have trouble seeing spatial relationships between objects around them.
Those with Fragile X syndrome are often very sensitive to loud noises; they may overreact or have outbursts in reaction to such sounds.
Congenital rubella
Metabolic Disorders
This group of functional birth defects affects a person's metabolism, which is the way the body builds up, breaks down, and otherwise processes the materials it needs to function. For example, how your body breaks down sugar to create energy is a metabolic process. Two commonly known metabolic disorders include:
Phenylketonuria(PKU)
Hypothyroidism
Degenerative Disorders
Some infants born with degenerative disorders appear normal at birth, but then lose abilities or functions due to the in condition. In these cases, the defect is usually not detected until an older age, when the child or person starts to show signs of loss of function. Some degenerative disorders are the result of metabolic disorders.
