#124 - Acting Out Dreams

Matt delves into the world of REM Sleep Behavior Disorder (RBD), a condition at the frontiers of sleep science. Normally, the brain dreams while atonia paralyzes the body in a neural magic act that is managed by brainstem nuclei activating inhibitory "brakes" in the spinal cord. When this circuit fails, the motor system remains active, enacting nightmares in real-time. RBD is hazardous - 10% of patients sustain injuries requiring medical intervention or hospitalization. It is a prodromal synucleinopathy where misfolded proteins erode the brain's architecture and 50% of patients develop Parkinson’s or Lewy body dementia within a decade. Matt concludes by noting that new skin biopsy biomarkers like Syn-One now offer hope for early detection.
