Premonitory Symptoms in Migraine: Implications for Disease Burden and Cognitive Impairment, with Some Promising Answers

Purpose: This study evaluated the prevalence and impact of premonitory symptoms (PS) in people with migraine, assessing their influence on disability, cognitive function, and quality of life. Methods: In a cross-sectional analysis at Mersin University Hospital, 186 migraine patients were interviewed to identify the presence of PS, using a structured questionnaire that included measures of disability (Migraine Disability Assessment Scale or MIDAS), quality of life (European Health Impact Scale or EUROHIS-8), and cognition (Migraine Attack Related Subjective Cognitive Scale or Mig-SCOG). Statistical analyses included descriptive statistics, the t-test, and the Mann-Whitney U-test, with a significance threshold set at p<0.05. Results: Among participants, 74.7% reported one or more PS, with the most common being neck stiffness (64.7%), photophobia (56.8%), fatigue (52.8%), and phonophobia (50.3%). Patients with PS demonstrated significantly lower quality of life scores (EUROHIS-8, p<0.001) and higher cognitive impairment scores (Mig-SCOG, p<0.001) than those without PS, despite similar levels of migraine disability (MIDAS, p=0.050). Conclusion: The high prevalence of PS in people with migraine and their association with greater cognitive impairment and reduced quality of life indicate that more targeted interventions are necessary in this subgroup. PS may be either a driver of cognitive and quality of life burden or just a marker of it, and disambiguating these possibilities will be a critical area for future research and clinical focus. More optimized and standardized prospective studies are needed to clarify the prevalence of PS.
