Level of Acceptance of Illness and Its Association with Quality of Life among Patients with Epilepsy in North Shewa, Ethiopia. Behav Neurol 2022; 2022:1142215. [PMID: 36134035 PMCID: PMC9484932 DOI: 10.1155/2022/1142215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 06/22/2022] [Accepted: 08/24/2022] [Indexed: 11/22/2022] Open
Abstract
Acceptance of illness is regarded as an indicator of functioning and predictor of quality of life. However, quality of life of patients with epilepsy in sub-Saharan countries worsen because of low medication adherence, increased morbidity and mortality, and the stigmatization associated with the disease. This research is aimed at assessing the level of acceptance of illness of patients with epilepsy and associated quality of life in North-East Ethiopia. Methods. A cross-sectional study was conducted from January to June 2021 at the Debre Berhan Referral Hospital, North-East Ethiopia. A total of 78 patients with epilepsy aged more than 18 years were randomly selected and assessed using Quality of Life in Epilepsy Inventory 31 and acceptance of illness scale. In addition, authors owned questionnaire were used to evaluate the sociodemographic and clinical characteristics of the patients. P value < 0.05 at 95% confidence level was considered to be statistically significant in all the analysis. Result. The study participants' age varied between 18 and 67 years with the mean age of 28.9 years. Phenobarbital was the most used (73.9%) antiepileptic drug, and 68.7% (n = 66) of the patients seizure was controlled. 72.9% (n = 70) of the patients had medium acceptance of illness (scored 20-30), while 17.7% (n = 17) had low illness acceptance level (scored 8-19), and 9.4% (n = 9) had high acceptance of illness (scored 31-40). The mean of overall acceptance of illness among epileptic patients was 21.04 ± 7.21. The overall score of QOLIE-31 was 79.14 ± 25.46, and the highest mean score was for cognitive (83.5 ± 27.1), while the lowest mean score was that of medication effect (72.7 ± 28.7). Five of the seven QOLIE-31 components correlated significantly with level of acceptance of illness. Cognitive domain (r = 0.498, p < 0.001) demonstrated the highest correlation followed by overall quality of life (r = 0.489, p < 0.001), seizure worry (r = 0.433, p < 0.001), energy/fatigue (r = 0.342, p < 0.001), and emotional well-being (r = 0.278, p < 0.001). Conclusion. Patients with epilepsy in the study area had medium acceptance of illness, and nearly half of them had mean and more than the mean quality of life. The patients' acceptance of illness was significantly associated with overall quality of life, seizure worry, emotional well-being, and cognitive domain of the patients.

Abstract
BACKGROUND The onset of epileptic seizures is influenced by weather, which is multifactorial. It is unknown which specific weather factors affect the occurrence of seizures. OBJECTIVES We studied the correlation between the onset of epileptic seizures and multiple weather parameters based on a population-based registry profile. METHODS We determined the number of patients who visited emergency services in Taiwan diagnosed as having epilepsy. Then we used a linear regression model to analyze the monthly average number of patients who received emergency treatment for epilepsy in relation to temperature, barometric pressure, accumulated precipitation, relative humidity, and hours of sunshine. The Poisson regression model was used to analyze multiple meteorological factors in relation to the number of daily emergency visits because of epilepsy. A receiver operating characteristic curve was used to determine the cutoff temperature for the occurrence of seizures. RESULTS Temperature appeared to be the robust factor for the onset of epilepsy. For every 1 °C decrease in temperature, there was a relative risk increase of 1.016 in the number of emergency visits as a result of epilepsy. Temperature lower than 18 °C had the best predictive value for seizure. Barometric pressure, accumulated precipitation, relative humidity, and the number of hours of sunshine were not related to the occurrence of seizures. SIGNIFICANCE Our results suggest that temperature is the only influential meteorological factor that affects seizure occurrence.

Abstract
Sudden and unexpected death in epilepsy (SUDEP) is the most common type of death among patients with epilepsy. Here, we address the importance of the experimental models in search of the mechanisms underlying SUDEP. Most studies have investigated the cardiovascular responses in animal models of epilepsy. However, there are few proposed SUDEP models in literature. Hypoventilation, apnea, respiratory distress, pulmonary hypertension, autonomic dysregulation and arrhythmia are common findings in epilepsy models. Impairments on adenosinergic and serotonergic systems, brainstem spreading depolarization, seizure-activation of neural substrates related to cardiorespiratory control, altered autonomic control, and mutations on sodium and potassium channels are hypothesis suggested. Overall, current research highlights the evident multifactorial nature of SUDEP, which involves acute and chronic aspects ranging from systemic to molecular alterations. Thus, we are convinced that elucidation and prevention of SUDEP can be achieved only through the interaction between basic and clinical science.

Abstract
Sudden unexpected death in epilepsy (SUDEP) is defined as sudden, unexpected, witnessed or unwitnessed, non-traumatic, and non-drowning death in a patient with epilepsy. Sudden unexpected death in epilepsy is probably the most common cause of epilepsy-related deaths. Many predisposing and initiating factors may coexist and contribute to SUDEP, but the mechanisms are poorly understood. Cardiac and respiratory deregulation seems to have a major role in SUDEP. Here, we review several advances in understanding the mechanisms involved in SUDEP.

Abstract
Epilepsy is one of the most common serious neurological conditions worldwide, and sudden unexpected death in epilepsy (SUDEP) is the main cause of epilepsy-related death. Although the exact pathophysiological causes of SUDEP are still unknown, potential risk factors include young age of epilepsy onset, duration of epilepsy, frequently recurrent seizures, winter temperatures and cardiac abnormalities such as arrhythmias during and between seizures. Unfortunately available pharmacological treatment for epilepsy remains limited in seizure control and consequently in SUDEP control, so alternative treatment should be considered in patients with refractory epilepsy. This article will revisit the possible related causes and preventative actions for SUDEP.
