Opioid abuse linked to mood and anxiety disorders

14.12.2011
New study provides support for a bi-directional pathway between non-medical prescription opioid use and opioid-use disorder due to non-medical use and several mood anxiety disorders

Individuals suffering from mood and anxiety disorders such as bipolar, panic disorder and major depressive disorder may be more likely to abuse opioids, according to a new study led by researchers from the Johns Hopkins Bloomberg School of Public Health. They found that mood and anxiety disorders are highly associated with non-medical prescription opioid use. The results are featured in a recent issue of the Journal of Psychological Medicine.

Prescription opioids such as oxycontin are a common and effective treatment for chronic and acute pain. Non-medical use of prescription opioids has increased dramatically and, according to the Substance Abuse and Mental Health Services Administration, prescription opioids are the second most frequently used illegal drug in the U.S. after marijuana. Prescription opioids are highly addictive and prolonged use can produce neurological changes and physiological dependence. For the study, researchers examined the association between individuals with mood and anxiety disorders with non-medical prescription opioid use and opioid disorder.

"Lifetime non-medical prescription opioid use was associated with the incidence of any mood disorder, major depressive disorder, bipolar disorder and all anxiety disorders. Non-medical opioid-use disorder due to non-medical prescription opioid use was associated with any mood disorder, any anxiety disorder, as well as with several incident mood disorders and anxiety disorders," said Silvia Martins, MD, PhD, lead author of the study and an associate scientist with the Bloomberg School's Department of Mental Health. "However, there is also evidence that the association works the other way too. Increased risk of incident opioid disorder due to non-medical use occurred among study participants with baseline mood disorders, major depressive disorder, dysthymia and panic disorder, reinforcing our finding that participants with mood disorders might use opioids non-medically to alleviate their mood symptoms. Early identification and treatment of mood and anxiety disorders might reduce the risk for self-medication with prescription opioids and the risk of future development of an opioid-use disorder."

Using data from the National Epidemiologic Study on Alcohol and Related Conditions (NESARC), a longitudinal face-to-face survey of individuals aged 18 years and older between 2001 to 2002 and 2004 to 2005, researchers assessed participants for a history of psychiatric disorders. Non-medical use of prescription opioids was defined to participants as using a prescription opioid without a prescription or in greater amounts more often or longer than prescribed or for a reason other than a doctor's instruction to use them. Logistic regression was used to determine whether lifetime non-medical prescription opioid use and opioid disorders due to this use predicted incident mood and anxiety disorders and the reverse. Researchers believe these findings provide support for a bi-directional pathway between non-medical prescription opioid use and opioid-use disorder due to non-medical use and several mood and anxiety disorders.

"With the current increased use of non-medical prescription drugs, especially among adolescents, the association with future psychopathology is of great concern. Using opioids, or even withdrawal from opioids, might precipitate anxiety disorders, suggesting that there is a subgroup of people who are vulnerable to future development of anxiety disorders," said Carla Storr, ScD, author of the study and an adjunct professor with the Bloomberg School's Department of Mental Health. Individuals using prescription opioids need to be closely monitored not only for the possibility of engaging in non-medical use, but also for the development of co-morbid psychiatric disorders.

"Additional studies are needed to examine the relationship between non-medical prescription opioid use and prescription opioid-use disorder with mood and anxiety disorders since they could co-occur due to shared genetic or environmental risk factors," Martins adds.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
