Research indicates that alexithymia overlaps with autism spectrum disorders (ASD).

Many causes of autism, including environmental and genetic factors, have been recognized or proposed, but understanding of the theory of causation of autism is incomplete. [1] Attempts have been made to incorporate the known genetic and environmental causes into a comprehensive causative framework. [ 2 ]

However, over time, there was increasing evidence that autism was instead a complex and highly heritable disorder whose core aspects have distinct causes which often co-occur. [ 34 ] [ 35 ] [ 36 ] Deletion (1), duplication (2), and inversion (3) are all chromosome abnormalities that have been implicated in autism.
A new study suggests diagnoses have increased at a faster clip among younger adults over the past decade. Autism spectrum disorder spiked 175% among people in the U.S. from 2.3 per 1,000 in 2011 ...
