Interhemispheric Attentional Functioning in Classic Migraine Subjects During Paroxysmal and Interparoxysmal Phases

SYNOPSIS To investigate whether recurrent neurological migraine prodromes may cause deterioration of higher brain functions, classic migraine patients with prodromes always on the same side ware submitted versus controls to a lateralized attentional task (Posner's test) at a short time interval from the headache attack (paroxysmal phase) and at a longer interval during the headache‐free period (interparoxysmal phase). The results indicate that classic migraine subjects showed no significant changes of interhemispheric attentional processing and interhemispheric balance. Some other findings which did not regard interhemispheric balance are discussed.
