West syndrome (WS) is the most common epileptic syndrome in infancy characterised by epileptic spasms, hypsarrhythmia and neurodevelopmental problems. Epileptic spasms remain in many ways a conundrum, and the ideal intervention, as well as how to screen patients to provide optimal care and certainly its genetic cause, remains puzzling. It is important to screen infants for early recognition and intervention to achieve the optimal outcome. We hereby discuss the approach to management of a boy aged 4½ years old with WS and behavioural problems and of parental expressed emotions.

AbstractWe aimed to analyse the ictal electrographic changes on scalp electroencephalography (EEG), focusing on high-voltage slow waves (HVSs) in children with epileptic spasms (ES) and tonic spasms (TS) and then identified factors associated with corpus callosotomy (CC) outcomes. We enrolled 17 patients with ES/TS who underwent CC before 20 years of age. Post-CC Engel’s classification was as follows: I in 7 patients, II in 2, III in 4, and IV in 4. Welch’s t-test was used to analyse the correlation between ictal HVSs and CC outcomes based on the following three symmetrical indices: (1) negative peak delay: interhemispheric delay between negative peaks; (2) amplitude ratio: interhemispheric ratio of amplitude values for the highest positive peaks; and (3) duration ratio: interhemispheric ratio of slow wave duration. Ages at CC ranged from 17–237 months. Four to 15 ictal EEGs were analysed for each patient. The negative peak delay, amplitude ratio and duration ratio ranged from 0–530 ms, 1.00–7.40 and 1.00–2.74, respectively. The negative peak delay, amplitude ratio and duration ratio were significantly higher in the seizure residual group (p = 0.017, <0.001, <0.001, respectively). Symmetry of ictal HVSs may predict favourable outcomes following CC for ES/TS.

The article is devoted to the treatment and prediction of outcomes of West syndrome. The analysis of literary and own data was carried out. Was estimated the effectiveness of treatment and predicted the outcomes of the disease by data of anamnesis, seizures and the possibilities of therapy. The article presents a stepwise scheme for the treatment of West syndrome and evaluates the results of the application of various drugs, including valproic acid, vigabatrin*, levetiracetam, phenobarbital, clonazepam and topiramate. Special attention is paid to the role of hormone therapy, demonstrated its high efficiency. The most significant prognostic criteria for the outcome of this disease are identified. These criteria are based on literature and our own data. Predictors of an adverse outcome of West syndrome include: symptomatic forms of disease (structural, genetic, infectious), impaired neuropsychological development before onset of epileptic spasms, age of spasms onset more than 8 months, the presence of other seizures types in addition to epileptic spasms, the need for polytherapy of antiepileptic drugs. The pathology of pregnancy, the period of adaptation, neonatal seizures, starting therapy and the response to it are not always important in predicting remission.
