Attention and executive functions in the early course of pediatric epilepsy.

OBJECTIVE: Our prospective study aimed at exploring attention and executive functions in children with new-onset epilepsy prior to and during the early course of antiepileptic treatment. Sociodemographic and epilepsy-related factors were analyzed as potential predictors both of impaired cognitive functions as well as for changes in cognitive functioning in the early course of illness. METHODS: From a total group of 115 children aged six to 17years without major disabilities, 76 children were assessed longitudinally with a screening tool for attention and executive functions (EpiTrack Junior®). Sociodemographic variables (gender, age at epilepsy onset, need of special education) and epilepsy-related variables (etiology of epilepsy, semiology of seizures, number of seizures) were considered as potential predictors for impaired functions prior to treatment and for deterioration/amelioration in cognitive functions in the early course. RESULTS: Attention and executive functions of children with new-onset epilepsy were significantly more often impaired when compared with a healthy population, but less often when compared with children with chronic epilepsy. The majority of children showed stable cognitive functioning in the early course of treatment. The risk of impaired cognitive functions was significantly heightened when etiology of epilepsy was unknown or not classifiable. The chance for improvement of functioning was lowered by having a genetic epilepsy, or an unknown semiology of seizures. CONCLUSIONS: Children with new-onset epilepsy are at high risk for impaired attention and executive functions even prior to antiepileptic treatment, especially when etiology of their epilepsy remains unclear. The high stability of cognitive functioning in the early course can be used in counseling of families who worry about negative side effects of drug treatment. Finally, a systematic assessment of cognitive functions in children with new-onset epilepsy is necessary to detect subtle deficits in the early course and adjust treatment accordingly.

Clinical spectrum and treatment outcome of 95 children with continuous spikes and waves during sleep (CSWS).

OBJECTIVE: Continuous spikes and waves during sleep (CSWS) is an epileptic encephalopathy characterized by generalised epileptiform activity and neurocognitive dysfunction. Causes and outcome are diverse and treatment is mainly empirical. METHODS: Retrospective descriptive analysis of clinical and EEG data of children with CSWS diagnosed between 1998 and 2018 at the University Hospital Heidelberg. RESULTS: Ninety-five children were included with a median age at diagnosis of 5.4 years. A structural/metabolic aetiology was found in 43.2%, genetic alterations in 17.9%, while it remained unknown in 38.9%. The proportion of patients with genetic aetiology increased from 10.3% (1998-2007) to 22.8% (2008-2018). On average, each patient received 5 different treatments. CSWS was refractory in >70% of cases, steroids and neurosurgery were most effective. No difference was observed between children with CSWS or Near-CSWS (Spike-Wave-Index 40-85%). CONCLUSIONS: Our cohort confirms CSWS as an age-dependent epileptic encephalopathy. Structural brain abnormalities were most frequent, but genetic causes are increasingly identified. More specific criteria for the diagnosis and treatment goals should be elaborated and implemented based on evidence. SIGNIFICANCE: This study is the largest monocentric observational study on treatment effects in children with CSWS, providing data for diagnostic and therapeutic decisions.

Attachment, symptom severity, and depression in medically unexplained musculoskeletal pain and osteoarthritis: a cross-sectional study.

BACKGROUND: Attachment insecurity relates to the onset and course of chronic pain via dysfunctional reactions to pain. However, few studies have investigated the proportion of insecure attachment styles in different pain conditions, and results regarding associations between attachment, pain severity, and disability in chronic pain are inconsistent. This study aims to clarify the relationships between insecure attachment and occurrence or severity of chronic pain with and without clearly defined organic cause. To detect potential differences in the importance of global and romantic attachment representations, we included both concepts in our study. METHODS: 85 patients with medically unexplained musculoskeletal pain (UMP) and 89 patients with joint pain from osteoarthritis (OA) completed self-report measures of global and romantic attachment, pain intensity, physical functioning, and depression. RESULTS: Patients reporting global insecure attachment representations were more likely to suffer from medically unexplained musculoskeletal pain (OR 3.4), compared to securely attached patients. Romantic attachment did not differ between pain conditions. Pain intensity was associated with romantic attachment anxiety, and this relationship was more pronounced in the OA group compared to the UMP group. Both global and romantic attachment anxiety predicted depression, accounting for 15% and 17% of the variance, respectively. Disability was independent from attachment patterns. CONCLUSIONS: Our results indicate that global insecure attachment is associated with the experience of medically unexplained musculoskeletal pain, but not with osteoarthritis. In contrast, insecure attachment patterns seem to be linked to pain intensity and pain-related depression in unexplained musculoskeletal pain and in osteoarthritis. These findings suggest that relationship-informed focused treatment strategies may alleviate pain severity and psychological distress in chronic pain independent of underlying pathology.
