This study was aimed at investigating the frequency of the visual phenomenon of palinopsia (visual perseveration) in patients with migraine.We interviewed 63 patients with migraine with aura (MwA), 137 patients with migraine without aura (MwoA) and 226 sex-age-matched healthy control subjects using an ad hoc structured interview/questionnaire. The interview was divided into four classes of variables for statistical testing.Palinopsia occurred in 19/200 patients (9.5%); of them 10/63 had MwA and 9/137 MwoA (14.2% vs 6.6%, chi = 9.7, degrees of freedom = 1, p = 0.002). Patients with palinopsia had a significantly lower migraine attack frequency than those without this visual phenomenon (4.3 ± 0.3 vs 14.4 ± 0.2, z = 7.1, p < 0.0001). No healthy control subjects complained of palinopsia according to the structured interview/questionnaire.Palinopsia is probably under-diagnosed in patients with migraine. Further investigations are needed to assess whether migraineurs are particularly susceptible to the development of recurrent episodes of visual perseveration.
