Abstract

fetched live from OpenAlex

OBJECTIVE: To document the long-term evolution of juvenile myoclonic epilepsy (JME) in a population-based cohort. METHODS: All patients developing JME by 16 years of age in Nova Scotia between 1977 and 1985 were contacted in 2006-2008. RESULTS: Twenty-four patients (17 women) had JME, 3.5% of all childhood-onset epilepsy. Age at first seizure was 10.4 +/- 4.3 years. We contacted 23 of 24 (96%) at a mean age of 36 +/- 4.8 years. All were initially treated with antiepileptic drugs (AEDs). At the end of a 25.8 +/- 2.4-year follow-up, 11 (48%) had discontinued treatment: 6 were seizure-free (without AEDs for 5-23 years), 3 had myoclonic seizures only (without AEDs for >18 years), and 2 continued with rare seizures. Convulsive status epilepticus occurred in 8 (36%) and 3 had intractable epilepsy. About 70% reported good satisfaction with their health, work, friendships, and social life (Likert scales). Despite 87% high school graduation, 31% were unemployed. Sixteen live with a partner, 7 alone. Nine received antidepressant medications. Ten women had > or =1 pregnancy and 4 men fathered a child. Eleven pregnancies (80%) were unplanned, outside of a stable relationship. At least 1 major unfavorable social outcome was noted in 76%. CONCLUSIONS: Our sample size is modest but the long follow-up and population-based sampling is unique. All seizure types in juvenile myoclonic epilepsy (JME) resolved in 17% and for 13%, only myoclonus persisted. Therefore, one-third of people with JME have troublesome seizures vanish and antiepileptic drug treatment is no longer needed. Depression, social isolation, unemployment, and social impulsiveness complicate the lives of many patients.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
