Cognitive functions in patients with vestibular migraine: Is there any difference from patients with migraine headaches only?
Abstract
BackgroundThe vestibular system contributes significantly to cognitive processes. Our study aims to detect the possible differences in cognitive function between patients with vestibular migraine (VM) and patients with migraine headaches only (MO).MethodsThis was a cross-sectional study. The participants took a number of tests during the same session: Mini Mental State Examination (MMSE), Stroop Test (ST), Digit Span Test (DST), Oktem Verbal Memory Process Test (OVMPT), Verbal and Nonverbal Cancellation Tests, Benton's Judgment Of Line Orientation Test (BJLOT), Rey-Osterrieth Complex Figure Test (ROCFT), Verbal Fluency Test (VFT), and Trail Making Test (TMT), in addition to Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI).ResultsThere were 97 participants (VM = 34, MO = 31, HC = 32), matched for age, sex, and education. Both patient groups had higher BAI scores than controls (p p p > 0.05). In the multivariable analyses, Stroop performance remained significantly worse in patients with VM, while DSFT and DSBT performance remained significantly worse in patients with MO (p p < 0.05).ConclusionIn conclusion, our study showed that attention, working memory, and spatial cognitive functions were affected in patients with VM. However, no overall cognitive differences were identified between patients with VM and patients with MO.
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 97 participants or records.
