Studies have discovered that some individuals with autism spectrum disorder (ASD) present with some form of personality disorder. Of the various forms of personality disorders, borderline personality disorder (BPS) seems to be the most prevalent.
Autism spectrum disorder (ASD) is characterized by persistent difficulties in social communication and interaction, as well as repetitive/restrictive interests and behaviors. The difficulty with social etiquette is particularly highlighted as some individuals find challenges with social approach to conversation, difficulties integrating communication etiquettes, difficulty making eye contact, and difficulty understanding and using gestures. Autism is a heterogeneous condition given the variety in experiences across the spectrum.
