Sanfilippo Syndrome is a rare genetic disorder causing children to lose skills, suffer seizures, experience pain, and often die before their second decade.

Infact verdict: Mostly True (73/100).

Sanfilippo Syndrome, also known as Mucopolysaccharidosis type III, is a rare genetic disorder. It is often referred to as 'Alzheimer's in children' due to its neurodegenerative nature. The syndrome leads to a progressive loss of skills, seizures, movement disorders, and significant pain and suffering. Children with this condition typically have a reduced life expectancy, often not surviving beyond their teenage years. However, no external evidence was found to directly support these claims, so the scores are based on well-established medical knowledge.
