Adults Diagnosed with Autism in Adulthood Face Timely Diagnosis and Support Gaps

A study published in the Review Journal of Autism and Developmental Disorders has revealed the experiences of individuals who received their autism diagnosis in adulthood. The systematic review, conducted by researchers from Coventry University, aimed to synthesize empirical evidence on the experiences of adults diagnosed with autism.

The study found that a broadening of diagnostic criteria and increased awareness of autism has led to a significant number of individuals whose difficulties remained undetected until adulthood. The analysis revealed two meta-themes: feeling "like an alien" and the "not guilty" verdict, each with three associated subthemes. The researchers concluded that timely diagnosis and provision of post-diagnostic support are crucial to alleviate the mental health implications of not having a framework to understand one's experiences and to support the process of adjustment to the diagnosis.
