Quality of life, fatigue and seizure severity in people living with epilepsy in a selected Nigerian population

Abstract

BackgroundEpilepsy, a chronic seizure disorder, can cause elevated fatigue and reduced quality of life (QOL) of the sufferers. Hence, improving QOL, seizure severity (SS) and fatigue are important areas of therapeutic interventions for people living with epilepsy (PLWE). Therefore, there is need to ascertain the levels and interrelationships among these constructs in PLWE. ObjectiveThis study compared fatigue and QOL of PLWE with those of apparently healthy individuals (AHIs) and also determined the interrelationships between fatigue, QOL and SS in PLWE. MethodThis cross-sectional survey involved 91 PLWE and 101 AHIs consecutively recruited from purposively selected hospitals and hosting communities. The Short-form Health Survey (SF-36) questionnaire, the Fatigue Severity Scale, the Modified Fatigue Impact Scale and the Seizure Severity Questionnaire were used to evaluate QOL, fatigue severity (FS), fatigue impact (FI) and SS respectively. Data was analyzed using frequency count, proportions, mean and standard deviation, range, Chi-square test, Mann-Whitney U test and Spearman-rank order correlation. Alpha level was set at 0.05. ResultsPLWE had significantly lower QOL compared to AHIs (U = 3057.00;p < 0.01). The two groups however experienced similar fatigue severity, but PWE suffered greater fatigue impact (U = 2798.00;p < 0.01). Significant relationships existed among FI, FS, SS and QOL in PLWE (p < 0.01). ConclusionCompared with AHIs, PLWE had poorer QOL, similar FS, and higher FI. QOL of PLWE was negatively associated with SS, FI and FS. Clinical interventions geared towards minimizing seizure, severity and impact of fatigue may improve the QOL of PLWE.
