Abstract

Objectives: Neurodivergent (ND) individuals (e.g., autistic people) are more likely to experience health problems that are characterised by ‘Central Sensitisation’ (CS). Recent research suggests that a so-called ‘Long-COVID’ syndrome might also be explained by a heightened response to internal physiological stimuli, much like in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). The primary objective of this study was to establish whether individuals who scored highly on a measure of CS would be more likely to experience long-term symptoms of COVID-19. A secondary aim considered if having a Type D personality was also linked to ongoing COVID-19 symptoms. Method: Using a standardised assessment tool, we examined whether traits associated with autism would predict long-term COVID-19 symptoms in 267 Healthcare Workers (HCWs). We also used a measure of Type D personality to establish if negative affect and social inhibition were related to Long-COVID. Results: A higher number of autistic traits predicted COVID-19 symptoms that lasted more than 12 weeks regardless of formal autism diagnosis. A personality measure also showed that negative affect was associated with experiencing COVID-19 symptoms for 4–12 weeks, though the direction of causality in this case is uncertain. Conclusions: Our main findings were (i) more HCWs scored above threshold for neurodivergence than those who were self-declared as having been diagnosed as neurodivergent; (ii) while there was no association between long-term COVID-19 and self-declared neurodivergent status, scores for the ‘sensory reactivity’ item of a standardised autism scale was predictive of COVID-19 symptoms lasting beyond 12 weeks post-infection; and (iii) HCWs with Type D Personality were not more likely to experience long-term COVID-19.
