8-year-old Carlos is brought to the clinic by his parents for a routine check-up. His parents report that he struggles with focusing on his schoolwork and often forgets instructions given to him during homework time. They are concerned because Carlos’s classmates seem to be progressing well in school, while Carlos’s performance has been inconsistent. Carlos’s parents believe he might have difficulty focusing because of the noise in their household, where there is often a lot of activity and conversation, especially during homework time.
