“Comorbidity” is a strange word, right? Well, at least for me it was. I have to admit it that it was the first scientific word I learned during my internship here at the National Institute on Drug Abuse (NIDA)–my Spanish accent still gives me a hard time pronouncing it. On the first day of my internship, I had to read and get acquainted with the extensive research that NIDA has done and published. Comorbidity was featured in NIDA’s Research Report Series.
So, what’s co-mor-bid-it-y? Here’s what NIDA scientists say: “When two disorders or illnesses occur in the same person, together or one after the other, they are called comorbid.” Having two disorders together can also cause them to interact in ways that make both of them worse.
So what does all of that really mean? It means that sometimes two illnesses go together. For example, people who have depression or other mental illness are often addicted to drugs as well, and vice versa, so that’s why scientists say depression is often “comorbid with” drug abuse.
NIDA scientists aren’t completely sure why people who are depressed are more likely to have a drug abuse problem. But here’s my take on it. Everyone has felt down before. If someone feels really bad, they may turn to drugs to “ease their mind.” Unfortunately, that can lead to a second disease–addiction to drugs–and then they feel even worse than they did before.
That’s what’s really bad about comorbid diseases: they can make each other worse! If someone is depressed, it’s harder to be motivated to quit using drugs. And if someone is using drugs, it can interfere with their treatment for depression.
What other diseases do you think could be comorbid? And why?

Every 9 ½ minutes: that's how often the Centers for Disease Control and Prevention (CDC) estimates that someone in the U.S. gets infected with HIV, the virus that causes AIDS. In the next 10 minutes, someone will get HIV—and it could be your friend or someone in your family.
By the way, do you remember the word for thought in my earlier post? Comorbidity? Well, HIV is one of the many diseases that is "comorbid with" drug use. NIDA's "Learn the Link" campaign is all about how drug use can expose us to infection from HIV. When someone is using drugs, their decisions may not be well considered. They can have poor judgment and do risky things, like having unprotected sex. And that might mean getting infected with HIV.
According to the CDC, by the end of 2007, 3,230 adolescents 13 to 19 years old were reported to be living with AIDS in the United States and dependent areas (like Puerto Rico). And unfortunately, more people are getting infected all the time.
June 27 was National HIV Testing Day. Did you get tested?
