Problematic TikTok use correlates with social anxiety and daily cognitive errors

Problematic TikTok use correlates with social anxiety and daily cognitive errors

A new study published in Addictive Behaviors Reports suggests that the anxiety of missing out on social events can fuel addictive behaviors on TikTok, which in turn leads to everyday memory and attention lapses. The researchers found that excessive use of the popular short video app acts as a bridge between underlying social anxieties and a person’s tendency to forget appointments or lose focus during daily tasks. These results highlight how the specific design of modern social media platforms might influence human brain function. Yao Wang, a researcher at the Centre for Cognitive and Brain Sciences at the University of Macau, led the investigation alongside colleagues from Germany and China. The research team set out to understand how particular psychological states push people toward excessive app usage. They wanted to see if these digital habits ultimately spill over into the physical world. The researchers focused heavily on a psychological concept known as the fear of missing out. This concept describes the persistent worry that others are having rewarding experiences without you. This feeling drives a …

Inflammation in a key dopamine hub correlates with depression severity

Inflammation in a key dopamine hub correlates with depression severity

Recent research identifies specific biological alterations in the brain’s reward center that correlate with depression. The study reveals that the physiological signs associated with a history of depression differ remarkably from the signs associated with the severity of current depressive symptoms. These findings appear in the journal Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. Depression is frequently understood as a disorder of mood, but growing evidence suggests it involves significant interactions with the body’s immune system. Biological responses to stress or illness often trigger inflammation. This immune response can affect the brain and disrupt the neural circuitry responsible for motivation and pleasure. The impact of inflammation on these brain networks may lead to anhedonia, which is the inability to feel pleasure and a primary symptom of depression. Central to this reward network is the ventral tegmental area. This small structure resides deep within the midbrain and serves as a primary source of dopamine. Dopamine acts as a chemical messenger that regulates motivation and goal-directed behavior. Disruption in the ventral tegmental area can lead to the lethargy …
