An “individual with a disability” is defined by the Americans with Disabilities Act as a person who: • Has a physical or mental impairment that substantially limits a “major life activity,” or • Has a record of such an impairment, or • Is regarded as having such an impairment. As we saw in Chapter 1, intellectual disability is arbitrarily defined in terms of having a low intellectual ability and low level of adaptive skills. Global data suggest that infection is a leading cause of chronic, developmental disability in children. An intellectual disability may be caused by genetic conditions, problems during pregnancy and birth, illness, or environmental factors.

Definition • A significant impairment of cognitive and adaptive functions, with age of onset before 18 years. If the child doesn’t get proper nutrition, he gets physically weak. Intellectual disability DS is the most common genetic cause of intellectual disability, which can be seen in nearly all PwDS [12]. Examples of genetic conditions are Down syndrome, fragile X syndrome, and phenylketonuria (PKU). Some of the most common known causes of intellectual disability include fetal alcohol syndrome; genetic and chromosomal conditions, such as Down syndrome and fragile X syndrome; and certain infections during pregnancy. SYNGAP1 mutations cause intellectual disability and autism. Any error in the coding like addition or deletion due to an infection during pregnancy, exposure to radiation, etc., can lead to intellectual disabilities. 2. 0000035700 00000 n Enhanced excitability during development is associated with premature development of dendritic spines, which may stunt their growth, thereby impairing intellectual potential. Genetic conditions – intellectual disabilities caused by genetics come from abnormal genes. This protein normally represses synaptic excitability during development. From the beginnings of the study of intellectual disability in the earliest part of recorded history to the more advanced efforts in the 21st century, the search for causation has been challenging. New emphasis on environmental factors The International Classification of Functioning, Disability and Health (ICF) (17) advanced the understanding and measurement of disability.

Abnormalities in genes and genetic inheritance can cause intellectual disability in children. Others happen while a baby is being born or soon after birth. Others happen while a baby is being born or soon after birth. Intellectual disability could cause a child to learn and develop more slowly than other children of the same age. Intellectual disability can also be caused by extreme malnutrition, lack of good medical care, or being exposed to poisons like lead or mercury. It is unlikely that all intellectual disability will fit neatly into these three groups − overlapping genetic, environmental and socio-cultural factors are likely to be relevant in many cases. For many children, the cause of their intellectual disability is not known. It could take longer for a child with intellectual disability to learn to speak, walk, dress, or eat without help, and they could have trouble learning in school.

Doctors have found many causes of intellectual disabilities. In children with severe intellectual disability, a biologic cause (most commonly prenatal) can be identified in more than 75% of cases. The most common biologic causes of mild intellectual disability include genetic or chromosomal syndromes with multiple, major, or minor congenital anomalies (velocardiofacial syndrome, Williams syndrome, Noonan syndrome), intrauterine growth restriction, prematurity, perinatal insults, intrauterine exposure to drugs of abuse (including alcohol), and sex chromosomal abnormalities. Some syndromes and health conditions The symptoms of intellectual disability begin during childhood or adolescence.
