Objective:
Increased prevalence of white matter hyperintensities (WMH) is reported in migraine patients; however, the pathophysiology and the progression of these lesions are not definitely clear. Mean platelet volume (MPV) and platelet distribution width (PDW) are easily obtained markers for platelet activity. The aim of this study is to evaluate the relationship between the presence of WMH and MPV and PDW in patients with migraine in order to determine the role of platelet activity in the pathophysiology of WMH.
Methods:
Patients who were admitted to the neurology outpatient clinics of Baskent University Hospital from January 2011 to December 2015 with migraine and between 18 and 55 years of age were evaluated retrospectively. The blood samples were taken and total blood count parameters including MPV and PDW were analyzed. Brain magnetic resonance images were evaluated.
Results:
Totally, 218 patients were evaluated in this study. Forty-eight (22.0%) patients had WMH in the brain magnetic resonance imaging. In patients with WMH, the median of age was higher than the patients without WMH and the difference was statistically significant (P < 0.05). There was no statistically significant difference between MPV, PDW values, and the presence of WMH.
Conclusions:
There are multiple theories suggested for the mechanism of WMH, but the major cause and pathophysiology are still undetermined. Our data suggested that increased platelet activity is insufficient by itself to explain the pathophysiology of WMH in migraine patients and to improve the knowledge on this issue further large longitudinal studies should be performed.
Insights
Platelet activity markers, mean platelet volume (MPV) and platelet distribution width (PDW), do not appear to explain white matter hyperintensities (WMH) in migraine patients. Further research is needed to understand WMH pathophysiology in migraine.
Area of Science:
- Neurology
- Hematology
Background:
- White matter hyperintensities (WMH) are increasingly observed in migraine patients, but their underlying causes and progression remain unclear.
- Platelet indices like mean platelet volume (MPV) and platelet distribution width (PDW) are indicators of platelet activation and may offer insights into WMH pathophysiology.
Purpose of the Study:
- To investigate the association between white matter hyperintensities (WMH) and platelet activity markers (MPV and PDW) in migraine patients.
- To explore the potential role of platelet activity in the development of WMH within the migraine population.
Main Methods:
- Retrospective analysis of 218 migraine patients (aged 18-55) treated at neurology outpatient clinics.
- Evaluation of brain magnetic resonance imaging (MRI) for the presence of WMH.
- Analysis of blood count parameters, including MPV and PDW.
Main Results:
- Forty-eight patients (22.0%) exhibited WMH on brain MRI.
- Patients with WMH were significantly older than those without WMH (P < 0.05).
- No statistically significant difference was found in MPV or PDW values between patients with and without WMH.
Conclusions:
- The study suggests that increased platelet activity alone is insufficient to account for the pathophysiology of WMH in migraine.
- Larger, longitudinal studies are recommended to further elucidate the mechanisms behind WMH in migraine patients.

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
