Clinical utility of reliable digit span in assessing effort in children and adolescents with epilepsy.

The assessment of effort is an important aspect of a comprehensive neuropsychological evaluation, as this can significantly impact data interpretation. While recent work has validated the appropriateness of adult-derived cutoffs for standalone effort measures in younger populations, little research has focused on embedded effort measures in children. The present study includes 54 clinically referred children and adolescents (32 males/22 females; aged 6-17) with a confirmed diagnosis of epilepsy.

The intracarotid amobarbital procedure: when is it worth repeating?

Purpose: Despite the reported diagnostic value of the intracarotid amobarbital procedure (IAP) or "Wada test" for determining hemispheric lateralization and memory functioning, it has never undergone formal reliability testing because a prospective test-retest study design is neither feasible nor ethical. However, some patients require repeat testing for clinical purposes, a circumstance that allows for exploration of issues related to reliability. The current investigation sought to: (1) evaluate the frequency of and reasons for repeated IAPs and (2) describe the test-retest reliability of repeated IAPs in a large tertiary epilepsy center.
