Cognitive impairment can occur at any age and cannot always be prevented. However, the following measures may be helpful:
A person with cognitive impairment can often live a nearly normal life. He or she can learn ways to deal with disability and take part in many activities. He or she may become so good at this that others may not notice the impairment. Even if the impairment is severe, rehabilitation therapy can help many people learn to function independently.
Cognitive impairments are not contagious and pose no risk to others.
