The ENCEVIS algorithm in the EMU and the factors affecting its performance: Our experience.

The study's purpose was to assess the seizure detection performance of ENCEVIS 1.7, identify factors that may influence algorithm performance, and explore its potential for implementation and application in long-term video EEG monitoring units. The study included video-EEG recordings containing at least one epileptic seizure. Forty-three recordings, encompassing 112 seizures, were included in the analysis. True positive, false negative, and false positive seizure detections were defined. Factors that may influence algorithm performance were studied. ENCEVIS demonstrated an overall sensitivity of 71.2%, significantly higher (75.1%) in focal compared to generalized seizures (62%). Ictal patterns rhythmicity (rhythmic 59.4 %, arrhythmic 41.7 %), seizure duration (<10 sec 6.3 %, >60 sec. 63.9 % (p < 0.05)) and patient age (<18 years 39.5 %, >18 years 58.1 % (P < 0.05)) influenced ENCEVIS sensitivity. The coexistence of extracerebral signal changes did not influence sensitivity. ENCEVIS with 79.1% accuracy annotates at least one seizure in those recordings containing epileptic seizures. ENCEVIS seizure detection performance was reasonable for generalized/focal to bilateral tonic-clonic seizures and seizures with temporal lobe onset. Rhythmic ictal patterns, longer seizure duration, and adult age positively influenced algorithm performance. ENCEVIS can be a valuable tool for identifying recordings containing seizures and can potentially reduce the workload of neurophysiologists.

Knowledge, attitudes, and stigma towards epilepsy in different walks of life: a study in Georgia.

We conducted a survey to assess public awareness of epilepsy and stigma expression in different social groups in Tbilisi, Georgia. Respondents were divided into those from a medical or paramedical background, those with a nonmedical professional background, and a group with unskilled workers or unemployed individuals. One thousand and sixteen people completed a Knowledge, Attitude and Perception questionnaire. Medical and paramedical professionals had a better general knowledge about epilepsy, its possible causes, and its nature, but their views on treatment and attitudes towards epilepsy were the same or worse when compared to the other groups. Of the respondent, 14% would not let their children play with people with epilepsy, and 75% would not allow their children to marry a person with epilepsy. Nearly a third of teachers considered epilepsy a psychiatric disorder. This suggests a high degree of stigma towards epilepsy in Georgia. Increasing awareness is crucial to ameliorate this.

The prevalence and treatment gap of epilepsy in Tbilisi, Georgia.

INTRODUCTION: Data on the prevalence of epilepsy and the extent of its treatment gap are important for planning health care delivery for people with epilepsy. The prevalence of active epilepsy in Georgia prior to the social and political re-organization in the early 1990s was estimated at around 5.7 per 1000. Changes to the social structure of the country may have affected this. There is no previous estimate of the treatment gap. METHODS: A door-to-door survey was carried out using a validated screening questionnaire to determine the prevalence of epilepsy and the extent of the treatment gap amongst a population of about 10,000 people in Tbilisi, the capital of Georgia. The diagnosis of epilepsy amongst those who screened positive was confirmed by a multidisciplinary team. RESULTS: Lifetime prevalence was 11.4/1000. The prevalence of active epilepsy was estimated at 8.8/1000, and 5/1000 had seizures in the previous 12 months. About two thirds of people with active epilepsy had not received appropriate antiepileptic treatment in the month prior to the survey. 89% had focal epilepsy and two thirds had co-morbidity (neurological deficits, behavioral, psychiatric or somatic problems). CONCLUSION: The prevalence of epilepsy was higher than previously estimated and the treatment gap was substantial. Results should inform the planning of epilepsy care delivery in the country.
