Serotonin Drop Linked to Memory Decline in Early Alzheimer’s Progression

Researchers discovered a potential link between lower levels of serotonin, the "happiness" chemical, and mild cognitive impairment (MCI), which could advance our understanding of Alzheimer's Disease (AD). Their study indicates that individuals with MCI have significantly reduced serotonin transporter levels, a factor that might contribute to memory problems and potentially AD.

Is Early Convalescent Plasma Treatment A Barrier to Long COVID?

Researchers found that early treatment with plasma from recovered COVID-19 patients reduces the risk of developing post-COVID conditions or "long COVID." The study revealed that patients who received the plasma, rich in SARS-CoV-2 antibodies, had a reduced hospitalization rate and fewer long COVID symptoms compared to those receiving a placebo.

A Fading Sense of Smell: New Predictor of Late-Life Depression?

Researchers identified a correlation between loss of smell and an increased risk of developing late-life depression. The study, spanning eight years and involving more than 2,000 older adults, doesn't establish causality but suggests that an impaired sense of smell might indicate overall health and well-being.

Psychedelics Unlock Learning Windows in the Brain

Researchers discovered a unique property of psychedelic drugs: their ability to reopen "critical periods" in the brain, times when the brain is highly susceptible to environmental learning signals. These periods, usually associated with skills development like language learning, are reopened by psychedelics for different lengths of time.
