AI Article Synopsis
- The study aimed to assess dynamic visual acuity (DVA) in migraine patients and explore its link to self-motion sensitivity and visually induced migraine symptoms.
- Researchers compared the DVA test results of 20 migraine patients with 20 control subjects during head movements, finding that migraine patients had significantly poorer DVA scores in four tested directions.
- The findings suggest that the abnormal DVA scores in migraine patients are related to their heightened sensitivity to head motion and visual stimuli, shedding light on the underlying mechanisms of migraine-related symptoms.
Article Abstract
Objective: To evaluate computerized dynamic visual acuity (DVA) test findings among patients with migraine and to determine whether self-motion sensitivity and visually induced migraine symptoms that are seen in migraine patients can be explained by DVA results.
Methods: Twenty migraine patients and twenty control subjects were evaluated with DVA test during rapid horizontal (left and right) and vertical (up and down) head movements. The subjects were asked to quickly recognize the direction of the Landolt-C optotype on the monitor while moving their heads. Test began with the largest optotype and progressively decreased in size by 0.1 logMAR until the subject could no answer correctly state the orientation of the optotype. DVA test scores of migraine group and control group were compared.
Results: Patient with migraine had significant DVA loss as compared with control subjects in four positions (left DVA, right DVA, up DVA, down DVA respectively p < 0.001, <0.001 = 0.001 and <0.001).
Conclusion: Migraine patients were found to have abnormal DVA scores mediated vestibular-ocular reflex. These abnormal DVA findings can explain the pathophysiology of head motion hypersensitivity and visual motion sensitivity that encountered by migraine patients.

Patient Factors Influence Minimal Clinically Important Difference for the SNOT-22 in Medically Treated Chronic Rhinosinusitis.
Int Forum Allergy Rhinol

Department of Otolaryngology-Head and Neck Surgery, University of Washington, Seattle, Washington, USA.
Background: The present study explores the effect of sociodemographics and comorbidities on the calculated minimal clinically important difference (MCID) for 22-item Sinonasal Outcome Test (SNOT-22) scores in patients with medically treated chronic rhinosinusitis (CRS). The importance of delineating a threshold to indicate clinically meaningful changes perceived by a patient is well acknowledged, yet the influence of patient-specific factors on MCID has not been fully elucidated.
Methods: Patients with CRS (n = 221) presenting to a tertiary care practice reported their change in disease burden with anchor questions following CRS-directed medical treatment.
Cardiovascular Safety of Anti-CGRP Monoclonal Antibodies in Older Adults or Adults With Disability With Migraine.
JAMA Neurol

Geriatric Research Education and Clinical Center, North Florida/South Georgia Veterans Health System, Gainesville, Florida.
Importance: Monoclonal antibodies (mAbs) targeting calcitonin gene-related peptide (CGRP) or its receptor (anti-CGRP mAbs) offer effective migraine-specific preventive treatment. However, concerns exist about their potential cardiovascular risks due to CGRP blockade.
Objective: To compare the incidence of cardiovascular disease (CVD) between Medicare beneficiaries with migraine who initiated anti-CGRP-mAbs vs onabotulinumtoxinA in the US.

Purpose Of Review: Migraine prevalence in females is up to 3 times higher than in males and females show higher frequency, longer duration, and increased severity of headache attacks, but the reason for that difference is not known. This narrative review presents the main aspects of sex dimorphism in migraine prevalence and discusses the role of sex-related differences in mitochondrial homeostasis in that dimorphism. The gender dimension is also shortly addressed.

Purpose: Benign paroxysmal positional vertigo (BPPV) is a vestibular disorder causing recurrent episodes of vertigo. Despite symptom resolution at discharge, events such as relapses, migraines, neck pain, falls, and persistent postural-perceptual dizziness (PPPD) may occur. This study aims to estimate the incidence, timing, and risk factors for these symptoms.

Background: There is evidence that iron metabolism may play a role in the underlying pathophysiological mechanism of migraine. Studies using (=1/ ) relaxometry, a common MRI-based iron mapping technique, have reported increased values in various brain structures of migraineurs, indicating iron accumulation compared to healthy controls.
Purpose: To investigate whether there are short-term changes in during a migraine attack.
