Complications

Children with progeria usually develop severe hardening of the arteries (atherosclerosis). This is a condition in which the walls of the arteries — blood vessels that carry nutrients and oxygen from the heart to the rest of the body — stiffen and thicken, often restricting blood flow.

Most children with progeria die of complications related to atherosclerosis, including:

• Problems with blood vessels that supply the heart (cardiovascular problems), resulting in heart attack and congestive heart failure
• Problems with blood vessels that supply the brain (cerebrovascular problems), resulting in stroke

Other health problems frequently associated with aging — such as arthritis, cataracts and increased cancer risk — typically do not develop as part of the course of progeria.
