BACKGROUND: Evidence suggests a prodromal phase in multiple sclerosis (MS) identifiable via healthcare use, including psychiatric symptoms. The association between psychiatric morbidity in this phase and future outcomes remains unclear.
OBJECTIVES: We investigated the association between psychiatric morbidity in the 5-years pre-MS onset and subsequent disability (EDSS) scores.
METHODS: We identified MS patients who visited an MS clinic in British Columbia, Canada (1991-2018) and linked their clinical and population-based health administrative data. Psychiatric morbidity was identified using physician/hospital visits in the 5-years pre-MS onset. Multivariable generalized linear models examined the association between psychiatric morbidity and subsequent EDSS scores. We explored effect modification by sex, age, and MS course and investigated if high psychiatric-related physician visits (>median) or hospitalizations (measures of "psychiatric morbidity burden") were associated with EDSS scores.
RESULTS: Among 2212 MS patients, 481 (21.7%) had psychiatric morbidity in the 5-years pre-MS onset. Follow-up averaged 5.2 (SD: 4.9) years (first-to-last EDSS assessment). Psychiatric morbidity pre-MS onset was associated with higher post-diagnosis EDSS scores (covariate-adjusted[adj) β = 0.17; 95% confidence interval (CI): 0.03-0.30). Associations were more pronounced in males (adjβ = 0.43; 95% CI: 0.04-0.83), <30 years (adjβ = 0.44; 95% CI: 0.15-0.73), relapsing-onset-MS (adjβ = 0.22; 95% CI: 0.08-0.37) and high psychiatric-related physician visit burden (adjβ = 0.23; 95% CI: 0.05-0.41), or hospitalizations (adjβ = 0.48; 95% CI: 0.002-0.96).
CONCLUSIONS: Psychiatric morbidity before MS recognition was associated with increased future disability, particularly in males, younger individuals, relapsing-onset-MS, and high pre-MS onset psychiatric morbidity burden.
