How does poor sleep in midlife impact brain health years later?

A study links poor sleep quality with accelerated neurodegenerative changes, suggesting that persistent sleep disturbances may expedite brain atrophy, warranting early therapeutic interventions to support cognitive health. Concurrently, data from JAMA Network Open Psychiatry reveal that social media use has complex effects on youth mental health, with excessive screen time and cyberbullying increasing risks for depression and suicide, while positive aspects like social connection may offer protective benefits. Finally, an implantable device, the Naloximeter, shows promise in mitigating opioid overdose fatalities by autonomously detecting respiratory depression and delivering naloxone, providing an advanced intervention for high-risk populations where immediate bystander response may be unavailable.
