What is the age of the oldest person with Rett syndrome?

As of my last update in October 2023, the oldest known person with Rett syndrome was reported to be in her 70s. Rett syndrome is a rare neurodevelopmental disorder that primarily affects females and typically leads to a range of physical and cognitive impairments. Due to the nature of the condition and advancements in medical care, individuals with Rett syndrome are living longer than in previous decades. However, specific records may vary, so checking the latest sources for updated information is advisable.
