Few vascular dementias are diagnosed in memory clinic consultations. One type, a
rare etiology, Sneddon syndrome, can lead patients to consult for an isolated
memory complaint. We report the cases of two patients, aged 63 and 66 years, who
presented frontocortical cognitive profile and behavior disorders. Seronegative
Sneddon syndrome, complicated with dementia, was diagnosed in each case by
noticing an association between, on MRI, an atrophy and several ischemic
cerebrovascular accident aftermaths, and a livedo racemosa. Management of
vascular risks factors improves the prognosis.
