This is a condition known as Hutchinson-Gilford Progeria Syndrome. It is a very rare condition that accelerates the aging process in children. The average life span for children with this disorder is 13 years of age.
Laymen have called it the “aging disease,” but the correct medical term is Hutchinson-Gilford Progeria Syndrome. The medical community generally refers to it as progeria. The word Progeria comes from the Greek progeros, meaning 'prematurely old'. Progeria is a rare, progressive, genetic disorder causing children to age rapidly.
