Internet addicts often suffer from additional disorders

Chatting via WhatsApp rather than meeting friends in real life, sharing holiday photos on Facebook rather than showing them in person, playing video games rather than going out. Digital media play an important role in our everyday lives. However, some people spend an excessive amount of time online, and they are unable to break free.

Internet addicts often suffer from concomitant disorders, most frequently from depressive disorders, anxiety disorders and ADHS. PD Dr med. Bert te Wildt studies this phenomenon at the Ruhr-Universität's LWL Clinic for Psychosomatic Medicine and Psychotherapy.

Spectrum of concomitant disorders similar to that in alcohol addicts

The researcher from Bochum has compiled a so-called comorbidity profile of 25 Internet addicts. Each patient presented at least one concomitant disorder. Together with his colleagues, Bert te Wildt examined 25 alcohol addicts for comparison. Their comorbidity profile was quite similar. However, only every other patient in this cohort suffered from a concomitant disorder. "These results highlight the significance of comorbidity for Internet addiction," says te Wildt. He also points out: "This is not a one-way street, the disorders interact." In another study, he found evidence that in a number of patients Internet addiction may be traced back to similar personality structures.

Large numbers presumably undetected

According to estimates, 500,000 Germans in the age bracket from 14 to 64 years suffer from Internet addiction, which most commonly takes the shape of online gaming addiction. The studies conducted by Bert te Wildt's team at the media outpatient clinic in Bochum suggest that many cases remain undetected.

Wearable tech for battlefield, people at risk for heart attacks

Wearable devices can count the steps you take and the calories you burn. But can they help soldiers in the field? Or prevent someone from having a heart attack?

Researchers at Sentient Science and the University at Buffalo say yes.

The sensor and software development company is working with UB engineering professor Albert H. Titus to create wearable technology that fuses real-time medical and physiological data with computer models. The system would then send personalized alerts indicating when the individual's level of stress, fatigue and resilience may put them in danger.

The work is funded by a $150,000 grant from the Office of Naval Research's Small Business Technology Transfer program, which enlists small businesses and research institutions to develop technology with military and commercial applications.

"Whether carrying 100 pounds of gear up a mountain or avoiding makeshift bombs, today's soldiers face incredible physical and mental stress," said Titus, PhD, professor and chair of UB's Department of Biomedical Engineering. "Our wearable system aims to measure how the body reacts to those challenges and combine that information with algorithms designed to help keep soldiers as safe as possible."

The wireless system, which is under development, will feature a series of electrodes that measure heart rate, brain activity and other vital signs. The electrodes may be attached to the skin like a Band-Aid or sewn into clothing that hugs the skin -- researchers are still deciding the best method.

The electrodes will relay information to a sensor (slightly smaller than a dime, attached to the skin like a patch), which will deliver that information to a remote computer network.

"It's like the hospital when you have a bunch of wires and equipment monitoring a patient. We're taking that technology and compressing it into a lightweight, wireless system," said the project's principal investigator Jennifer Haggerty, a research scientist and implementations manager at Sentient. Haggerty is an alumnus of UB.

As the information enters the computer network, it will fuse with Sentient's DigitalClone Live software, which has been validated by NASA and used to test the materials and components in the Hubble telescope, the F-35 fighter jet, wind turbines and other products.

The software includes complex algorithms that consider things like the terrain, weather and other environmental information, as well as the soldier's activity level. It will analyze the data and send personalized health alerts to soldiers and, if necessary, emergency medical facilities in the field. The idea is to improve soldiers' cognitive and physical abilities, making them more resilient and less prone to physical and psychological injuries.

In addition to serving the armed forces, the technology has commercial applications as a health-monitoring device. Sentient is exploring how the sensor can be applied to everyday items such as baseball caps. The individual wearing the cap would receive personalized health alerts regarding their risk of suffering a heart attack and other potential danger.
