Variability of alternating hemiplegia in children

Thе article describes two clinical cases of alternating hemiplegia (AH) in children of the same age group, but with different severity of clinical manifestations. The first patient, along with hemiplegic and epileptic seizures, demonstrates speech, behavioral and intellectual disorders, as well as motor disorders. The second patient, despite the presence of fairly frequent hemiplegic attacks, has no motor and intellectual disorders. The exact causes of such clinical variability are not yet known, which makes it difficult to predict the course in patients with AH.
