No one wants to have or suffer from any disability including intellectual disability. Everyone wants to live a normal life being physically and mentally healthy. However, there are some who were even born to have a physical or mental disability. Anyone who suffers from intellectual disability have a problem in learning, reasoning, and also problem solving. There are different types of intellectual disabilities. Those who suffer from one of these types have difficulty in communicating with others, even in learning and also in retaining information.
If a person have an IQ which is below 70 and is experiencing difficulty in socializing with other people or in his own safety, it could mean that he has an intellectual disability. The different types of intellectual disability includes Fragile X syndrome (FXS), Down Syndrome, developmental delay, Prader-Willi syndrome (PWS), and fetal alcohol spectrum disorder (FASD). These types of intellectual disability can be a cause of some environmental factors and other causes. It can be the result of problems during pregnancy such as viral or bacterial infections.
Other possible factors include complications during birth, exposure to toxins, malnutrition, trauma, and other possible causes. There are also four levels of this type of disability. These levels fall under the category of lifespan development disorders. Those who suffer from these disorders need to regularly consult a psychologist though they seem to have no intellectual problem at all. Mild intellectual disability, moderate intellectual disability, severe intellectual disability, and profound intellectual disability are the four levels of intellectual disability.
