Abstract

Alexithymia is a personality construct characterized by altered emotional awareness which has been gaining diagnostic prevalence in a range of neuropsychiatric disorders, with notably high rates of overlap with autism spectrum disorder (ASD). However, the nature of its role in ASD symptomatology remains elusive. Here, we distill research at the intersection of alexithymia and ASD. After a brief synopsis of the studies that plaid a pioneering role in the identification of the overlapping fields between alexithymia and ASD, we comb the literature for evidence of its overlap with ASD in terms of prevalence, etiology, and behaviors. Through a formalized framework of the process of emotional interpretation and expression, we explore evidence for where and how deficits arise in this complex network of events. We portray how these relate to the dynamic interplay between alexithymic and autistic traits and find emerging evidence that alexithymia is both a cause and consequence of autistic behaviors. We end with a strategic proposal for future research and interventions to dampen the impacts of alexithymia in ASD.

  • It is now generally thought that ALX commonly co-occurs with ASD due to shared underlying genetic and neurobiological factors rather than constituting a consequence of (or cause for) core characteristics of autism.

    “It is now generally thought that ALX commonly co-occurs with ASD due to shared underlying genetic and neurobiological factors rather than constituting a consequence of (or cause for) core characteristics of autism (see Bird & Cook, 2013; Poquérusse et al., 2018).”

    The Introduction acknowledges that alexithymia commonly co-occurs with ASD, and the section on diagnostic and etiological overlap reports possible shared genetic and neurobiological factors. But the Introduction explicitly presents evidence that alexithymia may be both a cause and a consequence of ASD symptoms, while “The Intersection Between Alexithymia and ASD” says their precise relationship remains unresolved. This contradicts the claim that shared factors are generally thought to explain the co-occurrence *rather than* either causal direction. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
