Background:
The influence of severity of migraine-like symptoms on different levels of executive functions is not well established. In this study, we investigate the impact of severity of migraine-like symptoms on the relationship between core-level executive functions (attention and memory) and fluid intelligence.
Methods:
A cross-sectional study was conducted on university students (n = 427, age = 20.7 + 1.8 years). Participants completed self-report measures of Migraine Screen Questionnaire (MS-Q), single-item visual analogue scales (VASs) each for the subjective accounts of problems in core-level executive functions (attention and memory), and a single-item VAS for problems in fluid intelligence (PFI), and sociodemographics tool. The mediation effect model was used to determine the relationship.
Results:
The study found a correlation between i) attention problems and severity of migraine-like symptoms (b = 0.109, standard error (SE) = 0.026, p < 0.001), ii) severity of migraine-like symptoms and memory problems (b = 0.318, SE = 0.076, p < 0.001), and iii) severity of migraine-like symptoms - PFI (b = 0.243, SE = 0.083, p < 0.003), with an indirect effect of attention problems on memory problems and PFI and no correlation between severity of migraine-like symptoms and PFI.
Conclusions:
Self-reported accounts of problems in core-level executive functions and fluid intelligence are correlated. Severity of migraine-like symptoms may mediate the inter-relationship between some core-level and higher-level executive functions.
