They seem to have totally missed testing migraine with aura, that data point should have been included by the senior researcher.

No association between migraine frequency, white matter lesions and silent brain infarctions: A study in a series of women with chronic migraine
Meilán A, Larrosa D, Ramón C
European Journal of Neurology|May 21, 2020
Since
silent infarctions (SIs) and hyperintense white matter lesions (WMLs)
are related to the frequency of migraine, researchers analyzed their
prevalence and anatomical distribution in chronic migraine (CM)
patients. In total, 96 women with CM [mean age 43 (range 16–65) years]
and 29 women with episodic migraine (EM) [mean age 36 (range
16–58) years] had 1.5‐T MRI following the CAMERA protocol. In 59 (61.5%)
women with CM and 17 (58.6%) women with EM, white matter lesions were
found. Compared with the anticipated prevalence at this age, this
investigation demonstrates that the prevalence of WMLs in CM and EM
has been increased, in most cases small, deep and frontal.
The results, however, do not support a combination of WMLs or SIs with a higher frequency of attacks but with the presence of vascular risk factors and mainly age > 45 years.
