Progeria is a rare genetic disorder that causes children to age rapidly, experiencing problems usually seen in the elderly like heart disease, stiffness of joints, and loss of hair and body fat. It affects around 50 children worldwide. Children with Progeria appear to have the appearance of an elderly person and most die of heart attacks or strokes at an average age of 13 years old. There is no cure for Progeria but treatments can help manage symptoms and delay the effects of aging.
