A new brain imaging study is giving experts insight into how medication used to treat ADHD works in the brain to soften symptoms associated with the neurological disorder. 

Common markers of Alzheimer's disease visualized on PET scans of asymptomatic patients might foreshadow the onset of symptoms in the years following their initial discovery.

The study, which was published in Brain and Behavior, found that individuals who used their smartphone excessively displayed different strengths in the prefrontal and parietal neural network.

Researchers involved in the study suggested that, until now, this sort of growth acceleration in adolescents had only been observed in children who had experienced extreme adversity, such as violence, neglect and family dysfunction. 

The study's authors explained how MRI results can be used to help identify children with ADHD—and how these findings could be used in the AI algorithms of tomorrow. The team will be presenting its findings at RSNA 2022 in Chicago. 

The regions that displayed the most significant differentiations in susceptibility values are known to be associated with neurological conditions such as fatigue, insomnia, anxiety, depression, headaches and other cognitive issues—all common complaints among many COVID long haulers. 

The findings were also found to be associated with the severity of symptoms in individuals with ASD.

Researchers recently presented a new method that considers how already existing lesions grow over time as an indicator of disease progression.
