Autism spectrum disorder and personality disorders: How do clinicians carry out a differential diagnosis?

Clare S Allely et al. Autism. 2023 Aug.

Abstract

It is now recognised that autism spectrum disorder (ASD) and personality disorders (PDs) have a variety of factors in common. However, the exact nature of the relationship between ASD and the PDs remains unclear. The overlapping symptom profiles of ASD and PDs can lead to diagnostic uncertainty - features of ASD and PD can be misattributed and easily lead to misdiagnosis of ASD patients. Since differentiating between ASD and PD is such a complex task, it has been argued that there is a need for additional understanding and markers for facilitating diagnostic procedures. There is an urgent need to explore, first, how clinicians make diagnostic decisions and, second, how to effectively deal with the challenges and difficulties they face when making decisions. Also, where there are clear overlaps, how do clinicians choose how to attribute labels in order to understand the person.
