Comorbidities are two or more diseases existing at the same time in the body. They are common for people with COPD because organ systems work differently when they do not receive enough oxygen. When a resulting condition occurs, it can be considered comorbidity.
ADHD occurs in 3% to 5% of the US population.1 The risk for comorbidity is high, and the presence of comorbid disorders warrants special consideration in the treatment of patients with ADHD. Comorbidity rates in adults are equal to or higher than those in children, although very few studies have examined these patterns over time in adults.
