Persian Depression Checklist Helps Teens With Epilepsy

What was studied

This study evaluated whether the Persian version of the Neurological Disorders Depression Inventory for Epilepsy (NDDI-E) is a valid and reliable tool for screening for depression in adolescents with epilepsy.

Researchers included 100 consecutively recruited adolescents ages 12 to 18 who were diagnosed with epilepsy at one children's hospital. There were 71 females and 29 males. Each participant completed the Persian NDDI-E questionnaire, and trained clinicians also conducted a K-SADS-PL interview, which was used as the reference standard for diagnosing depression.

What they found

The Persian NDDI-E showed good screening performance in this group. It had 81.48% sensitivity and 95.89% specificity for detecting depression. Depression was identified in 25% of adolescents by the NDDI-E and 27% by the K-SADS-PL interview. The questionnaire also showed good internal consistency, with a Cronbach's alpha of 0.82. The study found a significant association between juvenile myoclonic epilepsy and depression, while other seizure types were not associated with depression in this sample.

Limits of the evidence

This was a cross-sectional study, so it cannot show how depression or screening results may change over time. The study included only 100 adolescents from a single hospital, so the results may not apply to all adolescents with epilepsy or to other settings. The abstract does not report details such as confidence intervals, and it notes that larger multicenter studies are needed to confirm the findings.

For families and caregivers

For families, this suggests that a short Persian questionnaire may help clinics screen for depression in teens with epilepsy, especially in busy clinical settings. Still, a screening tool is not the same as a full mental health evaluation, and the findings need confirmation in larger studies.

What to watch next

Larger multicenter studies could help confirm these findings and show how well the questionnaire works in broader groups of adolescents with epilepsy.
