give and example of an severe intellectual disability

Severe intellectual disability, often characterized by significant limitations in cognitive functioning and adaptive behavior, can be exemplified by conditions such as Down syndrome or profound developmental delays. For instance, an individual with severe intellectual disability may have an IQ typically below 35, which impacts their ability to perform daily living skills, communicate effectively, and engage socially. Such an individual might require substantial support in areas like personal care, decision-making, and education. They might struggle with basic communication, understanding safety measures, or participating in community activities without assistance. A specific case could involve a child with severe intellectual disability who is unable to speak and requires help with daily tasks like feeding themselves or dressing, highlighting the profound impact of such a condition on daily life.
