Addictive Screen Use, Not Time, Tied to Teen Suicide Risk

A major new study reveals that teens who develop compulsive patterns of digital use are at higher risk of suicidal thoughts, attempts, and mental health issues. Unlike total screen time, it’s the addictive nature of use—such as distress when not online or using screens to escape—that most strongly predicts poor outcomes.

COVID-19 May Infect Dopamine Neurons

A new study reveals that SARS-CoV-2 can infect dopamine neurons, potentially linking to long COVID symptoms like brain fog and depression. The research shows that these neurons enter a state of senescence, ceasing to function and causing inflammation. This discovery was unexpected, as the study initially aimed to understand how different cell types respond to the virus, but found this unique pathway only in dopamine neurons.

Antiviral Pathway a Potential New Target for Alzheimer’s Treatment

Inhibiting cGAS, an innate immune system enzyme allows neurons to become more resilient to tau fibrils. The new finding may serve in the development of new therapies to help treat Alzheimer's disease and frontotemporal dementia, two neurodegenerative disorders associated with tau build-up in the brain.

Cognitive Decline May Be Triggered by Astrocyte Dysfunction

A new study reveals astrocyte dysfunction may be a driver of cognitive decline and memory loss in those with dementia. This may be caused by a protein build-up in the astrocytes that appears to trigger abnormal antiviral activity that results in memory loss.
