===Mental retardation===

[[Mental Retardation]]
The term mental retardation describes a certain range of scores on an IQ (intelligence quotient) test. Mental retardation can result from a number of different conditions, including (but not limited to):
 
  
===Down syndrome===
+
[[Down syndrome]]
It is a set of mental and physical characteristics related to having an extra copy of Chromosome 21.
 
  
===Fragile X syndrome===
+
[[Autism Spectrum Disorders]]
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.
 
  
===Autism Spectrum Disorders===
+
[[Fragile X syndrome]]
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.

=='''Sensory-related disabilities'''==
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.
 
  
'''Possible Indicators of Autism Spectrum Disorders'''

Sensory-related problems are often a key part of complex birth defect patterns. For instance:
  
Does not babble, point, or make meaningful gestures by 1 year of age

Children with congenital rubella are likely to be deaf, and to develop cataracts of the eyes.
  
Does not speak one word by 16 months
+
Children with Williams syndrome have trouble seeing spatial relationships between objects around them.
  
Does not combine two words by 2 years
+
Those with [[Fragile X syndrome]] are often very sensitive to loud noises; they may overreact or have outbursts in reaction to such sounds.
  
Does not respond to name

[[Congenital rubella]]
  
Loses language or social skills

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:
 
 
Poor eye contact
 
 
 
Doesn't seem to know how to play with toys
 
 
 
Excessively lines up toys or other objects
 
 
 
Is attached to one particular toy or object
 
 
 
Doesn't smile
 
 
 
At times seems to be hearing impaired

Phenylketonuria (PKU) - a condition in which a problem with a specific enzyme, a protein that speeds up certain chemical reactions, causes mental retardation.
 
Hypothyroidism - a hormonal condition that, if left untreated in an infant, can cause mental retardation.

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.

Degenerative disorders can cause physical, mental, and sensory problems, depending on the specific defect.Rett syndrome is an example of a degenerative birth defect. This disorder, which usually affects girls, is most often caused by a specific genetic abnormality.
