What is a common characteristic of Down syndrome?

A common characteristic of Down syndrome is intellectual disabilities. Individuals with Down syndrome often experience varying degrees of cognitive impairment, which can affect their learning abilities and overall intellectual functioning. This condition stems from the presence of an extra copy of chromosome 21, leading to developmental delays and challenges in areas such as reasoning, problem-solving, and adaptive skills.

In addition to intellectual disabilities, individuals with Down syndrome may face other health challenges, but intellectual disability is one of the most defining traits of this genetic condition. It is important to recognize that the level of intellectual disability can vary widely among those with Down syndrome, ranging from mild to moderate or severe.

The other options listed do not represent common characteristics of Down syndrome in the same way, as they are not universally experienced by individuals with the condition. While some may encounter health issues like visual impairments, they are not as ubiquitous as cognitive challenges associated with intellectual disabilities.
