[Contingent negative deviation in children with headaches].

Contingent negative deviation (CND) was studied in 26 children with migraine and in 20--with headache, tension-type, aged 7-14 years. A control group included 16 healthy subjects. The study was conducted during pain-free intervals, with a 3 s interval between the warning stimulus--S1 and the imperative one--S2. Children with migraine had a higher negative wave amplitude than those with headache, tension type, and controls. Patients suffering from headache had a characteristic postimperative negative wave in the postimpulse period. CND may be considered as an additional index of migraine diagnosis in childhood.

[Contingent negative variations in headache in children].

The paper presents a study concerning contingent negative variation (CND) in period between the attacks in 29 children with migraine, in 26 cases with a headache of tension (HAT) and in 16 healthy children. The age of the children examined was 7-14 years. The role of the age factor was shown in dynamics of the behavioral and electrophysiological CND parameters. Differences of electrophysiological CND parameters in children with migraine, in children with HAT and in healthy children of the same age are discussed as well as the results of the complex clinical-neurophysiological estimation of the efficiency of the prophylactic therapy in groups. CND method was considered to be quite perspective for differential diagnosis of primary headache in children.
