Nicholas Brendon’s death draws attention to cauda equina syndrome, a rare spinal emergency

Nicholas Brendon, the Buffy the Vampire Slayer star, died at 54 from natural causes after publicly battling cauda equina syndrome—a rare spinal emergency that can cause bladder/bowel loss, numbness, and leg weakness and requires urgent surgery within 24–48 hours to prevent permanent damage. Brendon underwent multiple spinal procedures after a 2021 fall and also faced heart-health issues (including a congenital defect and a prior heart attack) along with past substance use and mental health struggles.
