Dolan spent Christmas Day 2007 at his home in Foxrock in southeast Dublin with some friends. Later that evening, his illness suddenly worsened, and he was rushed by ambulance to the Mater Hospital. En route to the hospital, Dolan suffered a massive intracerebral haemorrhage, at which he became unconscious, and was connected to life support equipment upon his arrival. At approximately 14:30 hours on St Stephen's Day, surrounded by family and friends, the machines were switched off and Dolan died within 20 minutes, never regaining consciousness. He was pronounced dead at 15:03 hours. He was 68 years old.
