A recent study reveals a staggering 90% of autistic adults remain undiagnosed, particularly those over the age of 40. This lack of diagnosis means many individuals face significant challenges in accessing appropriate healthcare and support services. The research highlights that undiagnosed autism often leads to worsening health issues, as these individuals may not receive the tailored treatments and interventions they need. Experts emphasize the importance of improving diagnostic processes for adults to ensure better health outcomes and quality of life. Addressing these gaps in identification and support can help reduce the disparities faced by autistic adults in later life.
