Diagnosis and management of depression and psychosis in children and adolescents with epilepsy

Assessment of the Frequency of Depressive Symptoms in Epileptic Children (Single Center Study)

Background

Epilepsy, the most common neurological disorder in children, may present with many psychiatric comorbidities, the most common of which is depression.

Aim of the Work

We evaluated the frequency of depressive symptoms in epileptic children, with regard to the possible association between depression and their demographic data or seizure-related variables.

Patients and Methods

This cohort study was conducted on 80 children (6-13 years old) diagnosed as idiopathic epilepsy and were regularly recruiting the pediatric neurology clinic at Minya University Children Hospital. The Structured Birleson Depression Scale Questionnaire was used for assessment of presence of depressive symptoms, and Quality Of Life in Epilepsy (QOLIE-31) score was used to assess quality of life in those patients.

Results

Depressive symptoms were found in 37.5% of enrolled patients. There were statistically significant differences between the patients with depressive symptoms and the other group regarding age (p=0.001), residence (p=0.006) and past history of mood disorders (p=0.03). Sleep disturbance was the highest predictor of depression in cases with depressive symptoms, detected in 90% of cases, followed by appetite disturbance in 86.6% of cases, while delusions and hallucinations were the lowest, detected in only 10% of cases. Both duration of epilepsy and frequency of seizures were significantly higher in cases with depressive symptoms than the other group (p=0.001) for both. QOLIE score was significantly lower in cases with depressive symptoms than the other group (p= 0.01 for all).

Conclusion

Depressive symptoms are common in epileptic children, and it is often challenging and underestimated. It should be screened during the management of such children. Early diagnosis and more comprehensive package of care for depression in epileptic children will enable them to have a better quality of life.

Cognitive control deficits in pediatric frontal lobe epilepsy

Executive dysfunction and behavioral problems are common in children with epilepsy. Inhibition and shifting, both aspects of cognitive control, seem related to behavior problems and are thought to be driven mainly by the frontal lobes. We investigated if inhibition and shifting deficits are present in children with frontal lobe epilepsy (FLE). Secondly, we studied the relationship between these deficits and behavior problems. Thirty-one children were administered the Stroop Color Word Test and a digital version of the Wisconsin Card Sorting Test (WCST). Parents completed the Behavioral Rating Inventory for Executive Function (BRIEF) and the Achenbach scale (Child Behavior Checklist (CBCL)). About 20% of the children displayed significant low results on the Stroop Effect. About 60% showed shifting problems on the WCST. Parents reported cognitive control and behavioral deficits in about a third of the children. Also, behavioral problems and deficits in inhibition and shifting in daily life (BRIEF) seem to be related. There were no correlations between questionnaires and the Stroop and the WCST. Only in the group of children with many perseverative errors there were especially high correlations between Inhibit of the BRIEF.

Monitoring And Managing Depression In Adolescents With Epilepsy: Current Perspectives

Epilepsy is associated with a significantly increased risk of developing depressive disorder during adolescence. On the other hand, depression is highly detected in adolescents with epilepsy. These findings highlight the importance of early identification and proper management of comorbid depression in adolescent age. The prevalence of depressive disorders in adolescents with epilepsy ranges between 8 and 35% and is higher than the general population of the same age. The relationship between epilepsy and depression is complex and potentially bidirectional, thereby suggesting a common underlying pathophysiology. Furthermore, failure to detect and treat depressive disorder mostly in adolescence could lead to several negative implications such as an increased risk of suicidal ideation or behavior and poor quality of life. A number of methods are available to detect depressive disorder, such as psychiatric or psychological assessments, structured or semi-structured interviews, and self-report screening tools. Thus, physicians should be able to regularly screen depressive symptoms in youths with epilepsy. Recently, the NDDI-E-.Y inventory has been developed from the adult NDDI-E, and has been validated in many countries. NDDI-E-Y has showed reliable validity, being a brief screening tool (12 items) that can be easily included in routine epilepsy care. The first step to be considered for the management of depressive disorder in adolescents with epilepsy is to consider potential reversible causes of anxiety and depression (i.e., a new AEDs; seizure control). Secondly, great attention has to be given to the education of the child/adolescent and his/her family, trying to improve knowledge about epilepsy as well as to decrease parental stress and improving the child's sense of competence. Pharmacological treatment should also be considered in adolescents diagnosed with depression.

Are children affected by epileptic neuropsychiatric comorbidities?

Childhood-onset epilepsy is associated with psychiatric and cognitive difficulties and with poor social outcomes in adulthood. Some antiepileptic drugs adversely affect behavior in susceptible children with easy-to-control or refractory epilepsies, contributing to a high risk of psychological and psychiatric disturbance. Studies had demonstrated that patients with benign rolandic epilepsy and absence epilepsy had more aggressive behavior, depression, and anxiety disorders than control children. Psychiatric comorbidities are strongly associated with a poor long-term health-related quality of life in childhood-onset epilepsy, which suggests that comprehensive epilepsy care must include screening and long-term treatment for these conditions, even if seizures remit.

Epilepsy in children with intellectual disability in Bosnia and Herzegovina: effects of sex, level and etiology of intellectual disability

The purpose of this study was to examine the occurrence of epilepsy in children with intellectual disability. An additional goal was to determine if there were statistical differences in the occurrence of epilepsy related to the sex, level and etiology of intellectual disability of children. The sample consisted of 167 children with intellectual disability attending two special education schools in Sarajevo, Bosnia and Herzegovina. The method for data collection was the examination of the children's medical records. A chi-square test was performed to determine if there were any significant differences in the occurrence of epilepsy among different categories of children with intellectual disability. Additionally, Phi coefficient and Cramer V coefficient were calculated to determine the strength of association. The occurrence of epilepsy in children with intellectual disability is high and certain etiological categories are associated with an even higher risk of epilepsy. The study confirmed a high occurrence of epilepsy in children with intellectual disability. Some psycho-educational implications of epilepsy were discussed and in the future there should be better cooperation between medical and educational institutions in treating the bio-psycho-social issues of a child with epilepsy.

Alternative approaches to conventional antiepileptic drugs in the management of paediatric epilepsy

Over the last two decades, there has been a rapid expansion in the number and types of available antiepileptic drugs (AEDs), but there is increasing concern amongst parents and carers about their unwanted side effects. Seizure control is achieved in approximately 75% of children treated with conventional AEDs, but non-conventional (or non-standard) medical treatments, surgical procedures, dietary approaches, and other non-pharmacological treatment approaches may have a role to play in those with intractable seizures or AED toxicity. Many of the approaches are largely common sense and are already incorporated into our current practice, including, for example, avoidance techniques and lifestyle advice, while others require further investigation or appear to be impractical in children.

Determinants of outcome in childhood epilepsy

Possible outcomes with regard to seizures include remission (i.e. no seizures without drug treatment), conditional remission (i.e. no seizures under treatment) and treatment resistance. Several factors have been identified which are associated with favourable or unfavourable outcomes. These include syndrome diagnosis (benign vs severe epilepsy syndromes), seizure types (kind and number), severity of epilepsy, response to treatment (immediate vs delayed, monotherapy vs combinations), and concomitant neurological and psychiatric disorders. However, the quality of disease management by caretakers also has an important influence on the outcome. To determine full remission in patients who are seizure-free with treatment, antiepileptic drugs need to be tapered; generally speaking, this seems to be less risky in children than in adults. However, even if remission without treatment has been reached, an elevated risk of seizures may persist compared with that of the general population. The outcome of epilepsy should not be considered with respect to seizures alone, but should also include more global aspects of performance and quality of life. These may depend on the causes of epilepsy as much as, or more than, on the seizure disorder itself, but may also be related to treatment.
