Disease-, Age-Related Effects of HIV May Impact Driving Abilities of Middle-Aged and Older Adults

03.04.2014

Nearly half of people living with HIV experience cognitive deficits that may impact instrumental activities of daily living, including driving, according to University of Alabama at Birmingham School of Nursing research published in the March issue of the Journal of the Association of Nurses in AIDS Care.

“As the number of people aging with HIV increases, concerns mount that disease-related cognitive deficits may be compounded by age-related deficits,” said David E. Vance, Ph.D., associate director of the Center for Nursing Research and principal investigator of the research. “Disease-related deficits may be compounded by age-related deficits, which may further compromise everyday functions such as driving.”

UAB School of Nursing researcher David Vance says as the number of people aging with HIV increases, concerns mount that disease-related cognitive deficits may be compounded by age-related deficits.

In a cross-sectional pilot study funded by a pilot grant from the National Institutes of Health-funded UAB Center for AIDS Research, 26 adults age 40 and older were administered demographic, health, psychosocial and driving habit questionnaires, as well as cognitive assessments and driving simulator tests. While the study participants’ viral load — the level of HIV in one’s blood — was unrelated to driving performance, older age was related to poorer driving.

Study results also found that poorer visual speed-of-processing performance, including useful field of view, was related to poorer driving performance, which included average reaction times.

Mixed findings were observed between driving performance and cognitive function on self-reported driving habits of participants.

Previous studies have shown that individuals with HIV, especially as they age, exhibit lower cognitive performance than do uninfected individuals in the domains of speed of processing, psychomotor speed, executive functioning, and learning and memory.

The purpose of this study was to build on this existing research and examine driving simulator performance in an older sample of adults with HIV than in prior studies. The study had three key aims:

Examine relationships between demographic and mental and physical health variables and driving simulator outcomes

Examine relationships between cognitive and everyday functioning measures and driving simulator outcomes

Examine relationships between demographic and mental and physical health variables, and cognitive measures and driving simulator outcomes measures, as well as self-reported driving habits in older adults with HIV

Considering that, by 2015, nearly half of people living with HIV in the United States will be 50 years of age or older, Vance says this is an area that requires further research efforts.

“Driving is perhaps one of the most cognitively complex everyday activities, involving the ability to successfully negotiate one’s environment on the road by making quick decisions and attending and reacting to various stimuli,” Vance said. “The most pronounced and prevalent cognitive deficits in HIV are found in measures of speed and processing — functions essential to safe driving. Previous research shows 29 percent of adults with HIV have indicated a decreased driving ability. That alone means it’s an area that requires further examination.”

The UAB Edward R. Roybal Center for Translational Research in Aging and Mobility provided the infrastructure and facilities for this research. Greer Burkholder, M.D., assistant professor of infectious diseases, supplied information for the research from the UAB School of Medicine’s 1917 Clinic electronic medical database.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
