The article reports that higher ADHD symptom levels are linked to problematic social media use and problematic gaming, but this association is not explained by core cognitive deficits such as inhibitory control, reward sensitivity, or temporal processing. The findings suggest that cognitive deficits alone do not account for digital media problems, indicating potentially distinct underlying mechanisms for social media use and gaming.

The topic is of interest to psychology because it examines how neuropsychological factors relate to behavioral addictions and highlights the complexity of ADHD traits beyond cognitive deficits in understanding digital media behaviors.

Even with modern HIV drugs, HIV+ individuals have heightened neuroinflammation and cognitive deficits. Smokers with HIV had less neuroinflammation and better cognitive control. Obviously, smoking is harmful so they suggest we look into nicotine-related treatments.

Cigarette smoking is associated with reduced neuroinflammation and better cognitive control in people living with HIV - Neuropsychopharmacology

People living with HIV (HIV+) are roughly twice as likely to smoke cigarettes (Smok+) as the general population. With the advent of effective antiretroviral therapies, it is increasingly important to understand the effects of chronic HIV infection and cigarette smoking on brain function and cognition since HIV+ individuals have heightened neuroinflammation and cognitive deficits even with such therapies. Based on prior studies demonstrating that smoking reduces a marker for neuroinflammation in HIV- individuals, we hypothesized that HIV+/Smok+ individuals would have less neuroinflammation and better cognitive control than HIV+/Smok- individuals. Fifty-nine participants (HIV-/Smok- [n = 16], HIV-/Smok+ [n=14], HIV+/Smok- [n = 18], and HIV+/Smok+ [n = 11]) underwent baseline eligibility tests, positron emission tomography (PET) scanning to determine levels of a marker for neuroinflammation, and assessment of cognitive control with the reverse-translated 5-choice continuous performance test (5C-CPT), with smokers having smoked to satiety prior to testing. For the PET data, a significant effect of smoking status on whole brain (WB) standardized uptake value (SUV) was found between HIV+/Smok+ and HIV+/Smok- participants (due to 18.8% lower WB SUV in the HIV+/Smok+ group). HIV+/Smok- participants exhibited a mean 13.5% higher WB SUV than HIV-/Smok- participants. For the 5C-CPT, HIV+/Smok+ participants performed significantly better than HIV+/Smok- participants (d prime), and HIV+/Smok- participants performed worse than HIV-/Smok- participants. Thus, HIV+/Smok+ individuals demonstrated lower levels of the neuroinflammation marker and better cognitive control than HIV+/Smok- individuals. Given that HIV+ individuals whose HIV is well-controlled can still have chronic neurocognitive complications, study results suggest possible paths for future research into nicotine-related treatments to prevent such complications.

Air pollution and #braindamage: what the science says https://www.nature.com/articles/d41586-025-00053-y “Study after study has shown that higher levels of #airpollution are correlated with increased risks of #dementia, as well as higher rates of #depression, #anxiety and #psychosis. Researchers have also found links to neurodevelopmental conditions, such as #autism, and #cognitivedeficits in children”

Air pollution and brain damage: what the science says

Epidemiological studies have linked dirty air to dementia and other brain disorders. Now researchers are trying to determine how pollutants do their damage, and how much harm they cause.
