Characteristics and treatment of midlife-onset epilepsy: A 24-year single-center, retrospective study
Objective
This study aimed to analyze the clinical characteristics, etiology, and treatment of midlife-onset epilepsy in a real-world setting at a single center in China.
Methods
The clinical data of patients who attended the epilepsy clinic of the Department of Neurology, First Medical Center of Chinese PLA General Hospital from February 1999 to March 2023 were retrospectively analyzed. The clinical characteristics, etiology, and risk factors for midlife-onset epilepsy over the past 24 years were analyzed.
Results
Of the 969 patients with onset at 45–64 years of age, 914 were diagnosed with epilepsy with at least two unprovoked seizures 24 h apart. Of those, 99.7% (911) were of focal origin. The median duration from the initial seizure to follow-up treatment was 2 months (interquartile range [IQR]: 1.0–6.0 months). Before commencing treatment, 30.2% (207/683) of patients experienced more than two seizures. A structural etiology was found in 66.3% (606/914) of patients. Cerebrovascular disease (CVD) and traumatic brain injury (TBI) accounted for 19.9% (182/914) and 16.6% (152/914) of the cases, respectively. Logistic regression analysis showed that patients with abnormal imaging (odds ratio [OR] 2.04; 95% confidence interval [CI] 1.25–3.32; p = .004), focal seizures (OR 2.98; 95%CI 1.82–4.87; p < .001), and seizure clusters (OR 2.40; 95%CI 1.21–4.73; p = .01) had poor drug responses. Treatment outcomes were generally better in patients with epilepsy after CVD (OR .49; 95%CI .28–.85; p = .01). Treatment initiation after two seizures (OR .70; 95%CI .42–1.15; p = .16) or 6 months after the first seizure (OR 1.17; 95%CI .66–2.09; p = .58) did not result in poor drug effectiveness.
Significance
Midlife-onset epilepsy is typically of focal etiology, with CVD being the most common cause, and tends to respond well to medication. The median duration from the initial seizure to follow-up treatment was 2 months. Over 30% of patients experienced more than two seizures before commencing treatment, but this did not affect subsequent outcomes.
期刊介绍：
Epileptic Disorders is the leading forum where all experts and medical studentswho wish to improve their understanding of epilepsy and related disorders can share practical experiences surrounding diagnosis and care, natural history, and management of seizures.
Epileptic Disorders is the official E-journal of the International League Against Epilepsy for educational communication. As the journal celebrates its 20th anniversary, it will now be available only as an online version. Its mission is to create educational links between epileptologists and other health professionals in clinical practice and scientists or physicians in research-based institutions. This change is accompanied by an increase in the number of issues per year, from 4 to 6, to ensure regular diffusion of recently published material (high quality Review and Seminar in Epileptology papers; Original Research articles or Case reports of educational value; MultiMedia Teaching Material), to serve the global medical community that cares for those affected by epilepsy.
