Legendary DJ Casey Kasem will live out his final days this week surrounded by his children ... who have made the decision to withhold medication, food and fluids.
The judge in Casey's conservatorship case just reversed a ruling which required doctors to keep him alive with nourishment and meds.
The 82-year-old is currently in a Washington hospice facility.
Casey's kids tell TMZ ... their dad's health directive document states, "If the extension of my life would result in mere biological existence, devoid of cognitive function, with no reasonable hope for normal functioning, then I do not desire any form of life-sustaining procedures, including nutrition and hydration."
Casey's wife Jean was in court and furious over the judge's decision, storming out and screaming that the kids will have Casey's blood on their hands.
