Raynaud disease is characterized by episodic vasospasms of the arteries in the fingers and toes, causing them to turn pale, blue, and then red. Hemophilia is a genetic disorder that impairs blood clotting, an aneurysm is a bulge or weakness in an arterial wall that can rupture, and a cerebrovascular accident (stroke) is caused by a blockage or rupture of a blood vessel in the brain. None of these conditions involve vasospasms in the fingers and toes.
