What is the common cause of preventable mental retardation?
The most common known preventable or environmental cause of intellectual disability is fetal alcohol syndrome, the most common chromosomal cause is Down syndrome, and the most common genetic cause is Fragile X syndrome.
What four risk factors are associated with causes of intellectual disabilities?
Causes of intellectual disability can include:
- Infections (present at birth or occurring after birth)
- Chromosomal abnormalities (such as Down syndrome)
- Environmental.
- Metabolic (such as hyperbilirubinemia, or very high bilirubin levels in babies)
- Nutritional (such as malnutrition)
What are the known causes of intellectual disability?
Genetic/Inherited causes: e.g. Down Syndrome, the most common genetic condition associated with intellectual disability or Fragile X Syndrome, the most common identifiable inherited cause of intellectual disability.
What causes baby retardation?
An accident or mutation in genetic development may also cause retardation. Examples of such accidents are development of an extra chromosome 18 (trisomy 18) and Down syndrome . Down syndrome is caused by an abnormality in the development of chromosome 21. It is the most common genetic cause of mental retardation.
What are the two most common causes of intellectual disability?
The most common causes of intellectual disabilities are:
- Genetic conditions. Sometimes an intellectual disability is caused by abnormal genes inherited from parents, errors when genes combine, or other reasons.
- Complications during pregnancy.
- Problems during birth.
- Diseases or toxic exposure.
Is high functioning autism an intellectual disability?

What are the causes of disabilities?
Poverty and malnutrition. Poverty is one of the biggest causes of disability.
What causes special needs?
It is thought that learning disabilities may be caused by hereditary, teratogenic factors (for instance, alcohol or cocaine use during pregnancy), medical factors (premature birth, diabetes, meningitis of mother or offspring), and/or environmental factors (malnutrition, poor prenatal healthcare).
Why is it important to know about functional mental disorders?
Many people don’t understand that mental disorders are medical conditions, and require diagnosis and treatment just like any physical illness or injury. Learning about functional mental disorders will help erase the stigma associated with these disorders, and will help encourage people to seek medical help early.
What is functional impairment in the DSM?
Functional impairment is used as a criterion which must be fulfilled in order to render a diagnosis. Although never stated directly, the functional criterion in the DSM implies that a mental disorder must be associated with either distress or disability. As such, it helps establish the “threshold for the diagnosis of a disorder” 4.
What do we know about disabilities in mental disorders?
Disability in mental disorders is a well-known fact for many clinicians, policy makers and researchers, as well as caregivers and persons with mental illness. Yet the form, frequency and outcome of disabilities in mental disorders are not well-defined or studied scientifically.
What does impairment of mental functions mean?
To avoid a confusion, it is useful to note that the impairment of mental functions in the ICF generally corresponds to what is known as signs and symptoms of mental disorders (e.g., consciousness, orientation, energy, sleep, attention, memory, emotions). THE DIFFERENT ASPECTS OF FUNCTIONING IN THE DSM
