Study Links Common Cognitive Supplement L‑Tyrosine to Shorter Lifespan
Researchers analyzing data from over 250,000 UK Biobank participants found that genetically higher L‑tyrosine levels are associated with a reduced lifespan, particularly in men who lived about one year less on average. The Mendelian randomization approach isolated tyrosine’s effect, showing it to be more detrimental than its precursor phenylalanine.
Tetris and PTSD Symptoms: A Medical Perspective on Benefits, Limits, and Escalation
A Bayesian adaptive trial with 99 trauma‑exposed healthcare workers showed that a brief, guided Tetris‑based imagery‑competing task significantly reduced intrusive memories at four weeks and maintained benefits over follow‑up. The authors stress that the intervention targets a specific PTSD symptom rather than curing the disorder, positioning it as a digital adjunct within stepped‑care. They caution against oversimplified messaging like “just play Tetris,” highlighting the need for structured protocols, appropriate support, and clear escalation to evidence‑based trauma therapy. Limitations include a homogenous sample, self‑referral recruitment, and diary‑based outcomes.
