Quizplus · Accepted Answer

Spontaneous mutations are the most common cause of intellectual disabilities. These mutations occur randomly and affect the normal function of genes involved in brain development, leading to intellectual disability. In some cases, environmental factors such as infections or exposure to toxins may also cause intellectual disability, but these are relatively less common causes. Inherited genetic mutations (A and B) can also cause intellectual disability, but they are responsible for a smaller percentage of cases. It is important to note that intellectual disability can have a variety of causes, and in many cases, the exact cause may not be known.
