Effectiveness of methods of differential diagnosis of paroxysmal disorders of consciousness in children

Abstrast. Clinical, electrophysiological and neuroimaging methods used for differential diagnosis of different forms of epileptic and nonepileptic paroxysms in children in the early stages of the disease are considered. 527 patients aged 1 to 18 years were examined. As a result of a comprehensive survey, taking into account the data of video-electroencephalogram monitoring, 317 patients with epilepsy with a significant predominance of symptomatic forms of epilepsy were revealed, of which 166 (42,37%) patients had focal forms, 36 (11,36%) patients - generalized. A significant number of children were found to have conditionally symptomatic focal epilepsy - 94 (29,65%), only 4 (1,26%) patients - with Landau - Kleffner syndrome and a relatively small group - 17 (5,36%) patients with idiopathic epilepsy. Nonepileptic paroxysms were more common in boys in all age groups except for children from 1 to 3 years, but in this group of children the difference in the frequency of different paroxysms is insignificant (0,48%). In the frequency of nonepileptic paroxysms significantly prevailed in boys aged 3 to 6 years (13,33%) and 6 to 9 years (11,43%). In girls, nonepileptic paroxysms were more common at the age of 3 to 6 years (10,48%) and from 1 to 3 years (9,95%). A comprehensive examination allowed to differentiate children with epileptic and nonepileptic paroxysms and to clarify their diagnoses. With a refined diagnosis of nonepileptic paroxysms, 210 patients were found. The results indicate the need for a thorough comprehensive examination of children suffering from paroxysmal disorders of consciousness to avoid erroneous diagnosis.

Role of short-term out patient video electroencephalography in diagnosis of paroxysmal disorders

To distinguish epileptic seizures from non-epileptic paroxysmal events, we often use video electroencephalography (EEG) recording. Long-term video electroencephalography recording for inpatients is of good value, but, it necessitates much resources (financial and manpower). There is some evidence suggesting that short-term video EEG (STVEEG) is useful, but its role in practice has yet to be evaluated. To assess the usefulness of STVEEG in the diagnosis of different paroxysmal disorders and classifying epilepsy if present. Thirty sex patients had STVEEG recordings (for 2h) during a 15 months period. A diagnostic event was recorded in 21 of 36 (58.3%) within the first 2h of monitoring: PNES (n=11), epilepsy (n=5), and other paroxysmal disorders e.g. syncope, hemifacial spasm, movement disorder (n=5). STVEEG is a useful diagnostic technique in diagnosis of different paroxysmal disorders and it can be used as a successful screening test for saving other resources like prolonged inpatient video EEG recording.

Phenomenological assessment of psychogenic paroxysms using parameters of verbal activity

Under the revealing of the phenomenological features of psychogenic paroxysms (panic attacks and pseudoseizures) by the use of parameters of speech, the informativeness of these indicators for diagnosis of paroxysmal disorders was shown. The data obtained allowed psychogenic seizures to be divided into emotional, motor, and ideational levels of speech. The changes recorded by the data of speech rate characteristics indicate the shift of these parameters toward psychomotor excitement in the absence of the factor of “fear” in the structure of paroxysms (pseudoseizures or demonstrative seizures). In the case of seizures with a component of “fear” in the structure of paroxysms in patients with panic attacks, psychomotor inhibition was observed.
