Health-related quality of life in adolescents with psychogenic nonepileptic seizures.

The aim of this study was to evaluate the health-related quality of life (HRQoL) in adolescents with psychogenic nonepileptic seizures (PNESs) and to identify factors affecting the quality of life in these patients. Thirty-four adolescents with PNESs were compared to 30 adolescents without any psychiatric disorder. The Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present and Lifetime Version (K-SADS-PL) was applied to determine comorbid psychiatric disorders in the study group and to rule out any psychiatric disorder in the control group. The Pediatric Quality-of-Life Inventory (PedsQL) was used to assess the HRQoL. Physical HRQoL and psychosocial HRQoL, including emotional and school functioning, were found to be significantly lower in adolescents with PNESs. In the group with PNESs, the physical HRQoL and total HRQoL of adolescents with somatoform disorders other than PNESs and the emotional functioning of adolescents with major depressive disorder were worse than those of the adolescents without these comorbid psychiatric disorders. Seizure frequency and the duration of symptoms were not correlated with HRQoL scores. Treatment strategies in adolescents with PNESs should regard comorbid unexplained somatic symptoms and psychiatric disorders in addition to the reduction or cessation of seizures.
